Hatch v1.6.0

Hatch v1.6.0 brings improvements to build environments, better handling of dynamic metadata, and support for tools like Visual Studio Code.

Build environments

Originally, the environment interface method for providing builder sub-environments was intended to be used in conjunction with some cleanup logic in order to provide a fresh setup every time. However, this is unnecessary in practice because build dependencies rarely change.

Without caching, repeat build environment use is slow which affects the following scenarios:

Now a new environment interface method build_environment_exists is used by Hatch to determine whether or not it has already been created, for implementations that have a caching mechanism.

The virtual environment type now uses this method to cache build environments.

Project metadata

Dynamically defined metadata is now supported everywhere, thanks to the new caching of virtual build environments.

A project metadata command is introduced that displays the fully resolved metadata. The output format is JSON unless a field is specified as an argument.

For example, if you checkout a project that is built by Hatch, like FastAPI, and run:

hatch project metadata readme
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}

For example, if you checkout a project that is built by Hatch, like FastAPI, and run:
 
hatch project metadata readme
 
 
only the readme text will be displayed. If the content is in Markdown, then Rich will render it directly in your terminal:
 
FastAPI readme
 
Virtual environment location
 
The virtual environment type now uses a flat layout for storage in the configured virtual environment directory if the directory resides somewhere within the project root or if it is set to a .virtualenvs directory within the user's home directory.
 
For example, if you define the following Hatch configuration:
 
 
 
 
[dirs.env]
 virtual = ".hatch"
 
 
 
 
 
and the following matrix:
 
 
 
 
[[tool.hatch.envs.test.matrix]]
@@ -21,6 +21,6 @@
 ├── test.py3.9
 ├── test.py3.10
 └── test.py3.11
-
 
This flat structure is required for detection of virtual environments by tools like Visual Studio Code and PyCharm.
 
Additionally, the virtual environment type now supports a path option to specify an explicit path that all inherited environments will share, such as the common .venv.
 
Migration script improvements
 
The script used to migrate existing projects from setuptools has been improved to handle more edge cases that were encountered in the wild and now no longer modifies the formatting of existing pyproject.toml configuration.
 
Hatchling
 
Hatch now depends on Hatchling v1.11.0, which was also just released.
 
Environment version source
 
A new env version source is available that allows for the project version to be defined by an environment variable.
 
Relaxed version bumping
 
The standard version scheme now supports a validate-bump option that when set to false will forego the check when updating the version that the desired version is higher than the current version.
 
This use case comes from Project Jupyter:
 
 
A common pattern we use in Jupyter is to bump to a .dev0 minor version bump after making a release. If we have a bug fix that needs to go out in the interim, we'd rather not be forced to create a branch every time.

Hatch v1.8.0

Hatch v1.8.0 brings Python distribution management, static analysis and formatting backed by Ruff, and binaries for every platform.

Installation made easy

One thing that has been a perpetual problem for Hatch and other Python applications is that Python itself is a dependency. You, and more importantly your users, need to in some way get Python before your software can even be used. The recommended way to go about that is platform-dependent and even differs based on your target audience. I viewed this as a central UX problem for Hatch and so severe that I took a bit of a hiatus to solve it.

Luckily, I have to my satisfaction solved this problem in the form of PyApp. It is a runtime installer for Python projects written in Rust. Apps are distributed as standalone executables as users have come to expect and bootstrapping occurs upon the first invocation. Here is an example of what you would see the first time you run a binary from this release:

Installation example

Now that we have binaries, creating installers for different platforms becomes trivial. Starting with this release not only are binaries available for every platform but also we have installers for Windows and macOS. The installer for macOS is signed using a certificate from the same account used to sign the official distributions from https://www.python.org, so users will not get any security pop-ups. Shout out to @ewdurbin for their extreme generosity in setting up multiple certificates in their free time!

These installers and binaries are now the recommended way to install and update Hatch. These binaries have built-in management so you can update to the latest version by running hatch self update.

Windows signing

In future we will sign the installers for Windows but I did not have time to look into how that works. macOS signing took way longer than I anticipated 😅

Python management

For a long time I and other users have desired that Hatch gain the ability to manage Python distributions. In my mind this was always blocked on a better installation experience because there was sort of a chicken-or-egg problem where you want a Python manager but you first need Python. No longer is that the case!

The new python command group allows for easy installation of various distributions to arbitrary locations which are then added to your PATH by default. Hatch supports CPython and PyPy distributions:

Available Python distributions

Virtual environment Python resolution

The virtual environment type is now far more intelligent when resolving the parent distribution to use and guarantees that, when no specific version is requested, the resolved distribution will always be compatible with the project.

Additionally, when a requested version cannot be found on PATH it will automatically be downloaded and managed internally.

Static analysis

There is a new fmt command, backed entirely by Ruff, that checks and fixes your code for formatting and linting issues.

Starting with this release, Hatch maintains default settings that are guaranteed to be up-to-date and represent best practices for programming in modern Python. The idea is to provide defaults that are so broadly applicable that the majority of users will maintain little if any of their own overrides.

The default behavior is internal management of settings to provide an OOTB experience that works. It is recommended however that you persist the default config file in version control so that other tools like IDEs can utilize your full configuration.

Since Ruff is now provided as a built-in feature, new project templates no longer have such configuration and are much less verbose.

Build improvements

Building projects that do not use Hatchling as a backend is now supported and such builds are managed with the standard build tool.

The bridge between Hatch and the Hatchling CLI has been removed. Previously, the builder would send serialized messages to Hatch that would contain the desired content and style for each line of output. This was done in an effort to allow builder and build hook plugins to output pretty messages without actually requiring a dependency like Rich. A problem that arises with this is that builders that invoke subprocesses will not display ANSI codes as one might expect and will lose out on the interactive experience of such invocations, like the built-in binary builder plugin calling cargo build. So now everything is simpler at the expense of no colored output without manual logic, or adding a dependency if you're a third-party plugin.

Faster environment usage

Spawning a shell or running commands within environments always first checks that your project's dependencies are satisfied and if not synchronizes the environment with what is defined. Previously, this had the potential to be quite slow for projects that have many dependencies.

Now the set of dependency definitions is hashed and no check is performed if the hash is the same as before, significantly speeding up environment usage in most cases.

Hatchling

Hatch now depends on Hatchling v1.19.0, which was also just released.

Better defaults

Hatchling is all about providing the best possible defaults, even at the expense of backward compatibility. In this release, there are two breaking changes that provide a much better user experience and were in fact requested by users.

  • Both the force-include option and the force_include_editable wheel build data setting now raise errors if source paths do not exist.
  • The wheel build target now raises an error when no file inclusion options have been defined and none of its heuristics to determine what to ship are satisfied.

Binary build target

A new binary build target is now stable that allows for the building of standalone binaries for projects. This is what Hatch itself uses for its binaries.

Meta

Why Hatch?

A new page has been introduced that discusses the value proposition of Hatch and Hatchling in comparison to alternatives. Currently, it only addresses a few features but in future this page will become more comprehensive.

Future

Upcoming features include a test command, commands to manage dependencies, and workspaces functionality similar to Cargo that will make managing monorepos far easier.

Next year there will be two large efforts that you should expect to see:

  1. A significant amount of my free time (and some at work) will be devoted to introducing lock file functionality in Hatch and trying to get whatever that happens to be standardized.

    I met with @brettcannon about his thoughts post-PEP 665 and about mousebender. I also met with the prefix.dev team about rip and was fortunate enough to be shown a demo before its official announcement.

    At the moment, the two options I see are to either go all in and contribute to mousebender or rely on the Prefix folks and use rip. The latter has the benefit of potentially supporting Conda as a side effect with the downside of being quite new with the spec firmly out of our control. The former has the benefit of being able to easily gain institutional support from the Python packaging team and each of our employers with the downside being a significant amount of work needing to be done.

  2. When @henryiii is able to get some free time away from teaching I plan to work with him once again and push very hard for the Python build ecosystem to adopt the extensionlib approach.

    I am of the opinion that the Python community has not fully completed the expressed outcome of PEP 517 in that build backends are still (for the most part) reliant on setuptools for building non-Python code bases.

    Basically, there are components that interact with compilers to produce extension modules and components that pack files into an archive which we call a build backend. These are two distinct pieces of functionality and my view is that there should be an API that allows backends to consume extension module builders to find out where things got created and where they should be shipped inside archives.

    In this hypothetical future any build backend would be able to trigger the building of extension modules based on user configuration.

Hatch v1.9.0

Hatch v1.9.0 brings improvements to static analysis and important bug fixes.

Static analysis

The default version of Ruff has been increased to v0.1.8. This release brings formatting capabilities to docstrings and Hatch enables this by default with line length set to 80. This length was chosen as the default because it plays nicely with the rendering of the most popular themes for Python documentation, such as Material for MkDocs and Furo.

Additionally, it is now possible for projects to pin to specific versions of Ruff for upgrading at a later time:

[tool.hatch.envs.hatch-static-analysis]
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}      
 
  
   
 
 
 
  
 
 
  
 
 
 
 
 
 
  
 
 
 
    
Hatch v1.9.0
 
Hatch v1.9.0 brings improvements to static analysis and important bug fixes.
  
Static analysis
 
The default version of Ruff has been increased to v0.1.8. This release brings formatting capabilities to docstrings and Hatch enables this by default with line length set to 80. This length was chosen as the default because it plays nicely with the rendering of the most popular themes for Python documentation, such as Material for MkDocs and Furo.
 
Additionally, it is now possible for projects to pin to specific versions of Ruff for upgrading at a later time:
 
 
 
 
[tool.hatch.envs.hatch-static-analysis]
 dependencies = ["ruff==X.Y.Z"]
 
 
 
 
[envs.hatch-static-analysis]
 dependencies = ["ruff==X.Y.Z"]

Hatch v1.10.0
 
Hatch v1.10.0 brings a test command, support for UV, and a Python script runner.
  
Test command
 
The new test command allows you to easily run tests for your project on multiple versions of Python. The default behavior follows best practices, using pytest with select plugins for test execution and coverage.py for code coverage measurement.
 
The command is designed to be both simple to use while also satisfying the needs of most projects. For example, the following shows Hatch running tests for Jinja in all environments in the default matrix:
 
 
Testing Jinja example
 
 
Here is us testing Rich, with a bit of configuration:
 
 
Testing Rich example
 
 
See the tutorial for a detailed walk-through and the config reference for options.
 
UV
 
The package installer UV, brought to you by the same folks behind Ruff, is now supported. In any environment, you can set the installer option to uv to use UV in place of virtualenv & pip for virtual environment creation and dependency management, respectively. This often results in a significant performance benefit.
 
For example, if you wanted to enable this functionality for the default environment, you could set the following:
 
 
 
 
[tool.hatch.envs.default]
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}

The amount of displayed output is controlled solely by the -v/--verbose (environment variable HATCH_VERBOSE) and -q/--quiet (environment variable HATCH_QUIET) root options.
 
The levels are documented here.
 
Project awareness
 
No matter the mode, Hatch will always change to the project's root directory for entering or running commands in environments.
 
Tab completion
 
Completion is achieved by saving a script and then executing it as a part of your shell's startup sequence.
 
Afterward, you'll need to start a new shell in order for the changes to take effect.

Context formatting
 
 
You can populate configuration with the values of certain supported fields using the syntax of Python's format strings. Each field interprets the modifier part after the colon differently, if at all.
 
Global fields
 
Any configuration that declares support for context formatting will always support these fields.
 
Paths
 
  
 Field Description 
   
 root The root project directory 
 
 home The user's home directory 
  
 
All paths support the following modifiers:
 
  
 Modifier Description 
   
 uri The normalized absolute URI path prefixed by file: 
 
 real The path with all symbolic links resolved 
 
 parent The parent of the preceding path 
  
 
 
Tip
 
The parent modifier can be chained and may be combined with either the uri or real modifier, with the latter placed at the end. For example:
 
 
 
 
[tool.hatch.envs.test]
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}

Dependency configuration
 
 
Project dependencies are defined with PEP 508 strings using optional PEP 440 version specifiers.
 
Version specifiers
 
A version specifier consists of a series of version clauses, separated by commas. For example:

 matrix Its modifier selects the value of that matrix variable. If the environment is not part of a matrix or was not generated with the variable, you must specify a default value as an additional modifier e.g. {matrix:version:v1.0.0}. 
 
 verbosity The integer verbosity value of Hatch. A flag modifier is supported that will render the value as a CLI flag e.g. -2 becomes -qq, 1 becomes -v, and 0 becomes an empty string. An additional flag integer modifier may be used to adjust the verbosity level. For example, if you wanted to make a command quiet by default, you could use {verbosity:flag:-1} within the command.

The storage location for environments is completely configurable.
 
Unless an environment is explicitly selected on the command line, the default environment will be used. The type of this environment defaults to virtual.
 
 
Info
 
Environments prefixed by hatch- are used for special purposes e.g. testing.
 
 
Inheritance
 
All environments inherit from the environment defined by its template option, which defaults to default.

 macOS ~/Library/Application Support/hatch 
 
 Windows %USERPROFILE%\AppData\Local\hatch 
 
 Unix $XDG_CONFIG_HOME/hatch (the XDG_CONFIG_HOME environment variable default is ~/.config) 
  
 
You can select a custom path to the file using the --config root option or by setting the HATCH_CONFIG environment variable.
 
The file can be managed by the config command group.

Build environment configuration
 
 
You can fully alter the behavior of the environment used by the build command.
 
Dependencies
 
Build environments will always have what is required by the build system, targets, and hooks.
 
You can define dependencies that your builds may require in the environment as well:
 
 
 
 
[tool.hatch.envs.hatch-build]
+dependencies = [
+  "cython",
+]
+
 
 
 
[envs.hatch-build]
+dependencies = [
+  "cython",
+]
+
 
 
 
 
 
caution
 
It's recommended to only use the standard mechanisms to define build dependencies for better compatibility with other tools.
 
 
Environment variables
 
You can define environment variables that will be set during builds:
 
 
 
 
[tool.hatch.envs.hatch-build.env-vars]
+SOURCE_DATE_EPOCH = "1580601600"
+
 
 
 
[envs.hatch-build.env-vars]
+SOURCE_DATE_EPOCH = "1580601600"
+
 
 
 
 
Installer
 
By default, UV is enabled. You may disable that behavior as follows:
 
 
 
 
[tool.hatch.envs.hatch-build]
+installer = "pip"
+
 
 
 
[envs.hatch-build]
+installer = "pip"

Environments
 
 
Environments are designed to allow for isolated workspaces for testing, building documentation, or anything else projects need.
 
Unless an environment is chosen explicitly, Hatch will use the default environment.
 
 
Tip
 
For a more comprehensive walk-through, see the Basic usage tutorial.
 
 
Creation
 
You can create environments by using the env create command. Let's enter the directory of the project we created in the setup phase:

How to configure custom dynamic metadata
 
 
If you have project metadata that is not appropriate for static entry into pyproject.toml you will need to provide a custom metadata hook to apply such data during builds.
 
 
Alternatives
 
Dynamic metadata is a way to have a single source of truth that will be available at build time and at run time. Another way to achieve that is to enter the build data statically and then look up the same information dynamically in the program or package, using importlib.metadata.
 
If the version field is the only metadata of concern, Hatchling provides a few built-in ways such as the regex version source and also third-party plugins. The approach here will also work, but is more complex.
 
 
Update project metadata
 
Change the [project] section of pyproject.toml:
 
     
  1. Define the dynamic field as an array of all the fields you will set dynamically e.g. dynamic = ["version", "license", "authors", "maintainers"]
    2.  
  2. If any of those fields have static definitions in pyproject.toml, delete those definitions. It is verboten to define a field statically and dynamically.
    3.  
 
Add a section to trigger loading of dynamic metadata plugins: [tool.hatch.metadata.hooks.custom]. Use exactly that name, regardless of the name of the class you will use or its PLUGIN_NAME. There doesn't need to be anything in the section.
 
If your plugin requires additional third-party packages to do its work, add them to the requires array in the [build-system] section of pyproject.toml.
 
Implement hook
 
The dynamic lookup must happen in a custom plugin that you write. The default expectation is that it is in a hatch_build.py file at the root of the project. Subclass MetadataHookInterface and implement update(); for example, here's plugin that reads metadata from a JSON file:
 
 
 
 
import json
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}

How to configure dependency resolution
 
 
Most Hatch environment types, like the default virtual, simply use pip to install dependencies. Therefore, you can use the standard environment variables that influence pip's behavior.
 
Here's an example of setting up the default environment to look at 2 private indices (using context formatting for authentication) before finally falling back to PyPI:
 
 
 
 
[tool.hatch.envs.default.env-vars]

How to select the installer
 
 
Enabling UV
 
The virtual environment type by default uses virtualenv for virtual environment creation and pip to install dependencies. You can speed up environment creation and dependency resolution by using UV instead of both of those tools.
 
 
caveat
 
UV is under active development and may not work for all dependencies.
 
 
To do so, set the installer option to uv. For example, if you wanted to enable this functionality for the default environment, you could set the following:
 
 
 
 
[tool.hatch.envs.default]
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}

How to use Hatch environments from Visual Studio Code
 
 
Visual Studio Code announced support for Hatch environment discovery in vscode-python's 2024.4 release.
 
For it to work, you should install Hatch globally. If you used the GUI installers on Windows or macOS, or your system package manager on e.g. Arch Linux or Fedora, this should be taken care of.
 
 Setting up PATH 
If you installed Hatch with pipx rather than system-wide, you might need to add $HOME/.local/bin to your PATH environment variable for your graphical session, not just your terminal. Check like this:
 
$ pgrep bin/code  # or some other graphical application
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}

How to authenticate for index publishing
 
 
The username is derived from the following sources, in order of precedence:
 
     
  1. The --user / -u cli option.
    2.  
  2. The HATCH_INDEX_USER environment variable.
    3.  
  3. The repos tables.
    4.  
  4. The ~/.pypirc file.
    5.  
  5. The input to an interactive prompt.
    6.  
 
As a fallback the value __token__ is applied.
 
The password is looked up in these:
 
     
  1. The ~/.pypirc file if the username was provided by it.
    2.  
  2. The --auth / -a cli option.
    3.  
  3. The HATCH_INDEX_AUTH environment variable.
    4.  
  4. The repos tables.
    5.  
  5. A variety of OS-level credentials services backed by keyring.
    6.  
  6. The input to an interactive prompt.
    7.  
 
If interactively provided credentials were used, the username will be stored in Hatch's cache and the password stored in the available keyring backed credentials stores.
 
For automated releasing to PyPI, it is recommended to use "Trusted Publishing" with OIDC (e.g. PyPA's pypi-publish GitHub Action) or per-project API tokens.

The username is derived from the following sources, in order of precedence:
 
     
  1. The --user / -u cli option.
    2.  
  2. The HATCH_INDEX_USER environment variable.
    3.  
  3. The repos tables.
    4.  
  4. The ~/.pypirc file.
    5.  
  5. The input to an interactive prompt.
    6.  
 
As a fallback the value __token__ is applied.
 
The password is looked up in these:
 
     
  1. The ~/.pypirc file if the username was provided by it.
    2.  
  2. The --auth / -a cli option.
    3.  
  3. The HATCH_INDEX_AUTH environment variable.
    4.  
  4. The repos tables.
    5.  
  5. A variety of OS-level credentials services backed by keyring.
    6.  
  6. The input to an interactive prompt.
    7.  
 
If interactively provided credentials were used, the username will be stored in Hatch's cache and the password stored in the available keyring backed credentials stores.
 
For automated releasing to PyPI, it is recommended to use "Trusted Publishing" with OIDC (e.g. PyPA's pypi-publish GitHub Action) or per-project API tokens.

How to configure repositories for index publishing
 
 
You can select the repository with which to upload using the -r/--repo option or by setting the HATCH_INDEX_REPO environment variable.
 
Rather than specifying the full URL of a repository, you can use a named repository from a publish.index.repos table defined in Hatch's config file:
 
 
 
 
[publish.index.repos.private]
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}

The following repository names are reserved by Hatch and cannot be overridden:
 
  
 Name Repository 
   
 main https://upload.pypi.org/legacy/ 
 
 test https://test.pypi.org/legacy/

How to use custom Python distributions
 
 
The built-in Python management capabilities offer full support for using custom distributions.
 
Configuration
 
Configuring custom Python distributions is done entirely through three environment variables that must all be defined, for each desired distribution. In the following sections, the placeholder <NAME> is the uppercased version of the distribution name with periods replaced by underscores e.g. pypy3.10 would become PYPY3_10.
 
Source
 
The HATCH_PYTHON_CUSTOM_SOURCE_<NAME> variable is the URL to the distribution's archive. The value must end with the archive's real file extension, which is used to determine the extraction method.
 
The following extensions are supported:
 
  
 Extensions Description 
   
 
  • .tar.bz2
  • .bz2
 A tar file with bzip2 compression 
 
 
  • .tar.gz
  • .tgz
 A tar file with gzip compression 
 
 
  • .tar.zst
  • .tar.zstd
 A tar file with Zstandard compression 
 
 
  • .zip
 A ZIP file with DEFLATE compression 
  
 
Python path
 
The HATCH_PYTHON_CUSTOM_PATH_<NAME> variable is the path to the Python interpreter within the archive. This path is relative to the root of the archive and must be a Unix-style path, even on Windows.
 
Version
 
The HATCH_PYTHON_CUSTOM_VERSION_<NAME> variable is the version of the distribution. This value is used to determine whether updates are required and is displayed in the output of the python show command.

How to run Python scripts
 
 
The run command supports executing Python scripts with inline metadata, such that a dedicated environment is automatically created with the required dependencies and with the correct version of Python.
 
A script metadata block is a comment block that starts with # /// script and ends with # ///. Every line between those two lines must be a comment line that starts with # and contains a TOML document when the comment characters are removed.
 
The top-level fields are:
 
     
  • dependencies: A list of strings that specifies the runtime dependencies of the script. Each entry must be a valid dependency specifier.
    •  
  • requires-python: A string that specifies the Python version(s) with which the script is compatible. The value of this field must be a valid version specifier.
    •  
 
The following is an example of Python script with a valid metadata block:
 
 
 
 
# /// script
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}

Customize static analysis behavior
 
 
You can fully alter the static analysis performed by the fmt command by modifying the reserved environment named hatch-static-analysis. For example, you could define the following if you wanted to replace the default behavior with a mix of Black, isort and basic flake8:
 
 
 
 
[tool.hatch.envs.hatch-static-analysis]

    FAQ
     
     
    Interoperability
     
    Q: What is the risk of lock-in?
     
    A: Not much! Other than the plugin system, everything uses Python's established standards by default. Project metadata is based entirely on the standard, the build system is compatible with PEP 517/PEP 660, versioning uses the scheme specified by PEP 440, dependencies are defined with PEP 508 strings, and environments use virtualenv.
     
    Q: Must one use all features?
     
    A: No, all features are optional! You can use just the build system, publish wheels and source distributions that were built by other tools, only use the environment management, etc.
     
    Libraries vs applications
     
    Q: Are workflows for both libraries and applications supported?
     
    A: Yes, mostly! Applications can utilize environment management just like libraries, and plugins can be used to build projects in arbitrary formats or publish artifacts to arbitrary destinations.
     
    The only caveat is that currently there is no support for re-creating an environment given a set of dependencies in a reproducible manner. Although a standard lock file format may be far off since PEP 665 was rejected, resolving capabilities are coming to pip. When that is stabilized, Hatch will add locking functionality and dedicated documentation for managing applications.

    Plugins
     
     
    Hatch utilizes pluggy for its plugin functionality.
     
    Overview
     
    All plugins provide registration hooks that return one or more classes that inherit from a particular type interface.
     
    Each registration hook must be decorated by Hatch's hook marker. For example, if you wanted to create a new kind of environment you could do:
     
     
     
     
    from hatchling.plugin import hookimpl

    Build hook plugins
     
     
    A build hook provides code that will be executed at various stages of the build process. See the documentation for build hook configuration.
     
    Known third-party
      
    Overview
     
    Build hooks run for every selected version of build targets.
     
    The initialization stage occurs immediately before each build and the finalization stage occurs immediately after. Each stage has the opportunity to view or modify build data.
     
    Build data
     
    Build data is a simple mapping whose contents can influence the behavior of builds. Which fields exist and are recognized depends on each build target.
     
    The following fields are always present and recognized by the build system itself:
     
      
     Field Type Description 
           
     artifacts list[str] This is a list of extra artifact patterns and should generally only be appended to 
     
     force_include dict[str, str] This is a mapping of extra forced inclusion paths, with this mapping taking precedence in case of conflicts 
     
     build_hooks tuple[str, ...] This is an immutable sequence of the names of the configured build hooks and matches the order in which they run 
          
     
     
    Attention
     
    While user-facing TOML options are hyphenated, build data fields should be named with underscores to allow plugins to use them as valid Python identifiers.
     
     
    Notes
     
    In some cases it may be necessary to use force_include rather than artifacts. For example, say that you want to install a lib.so directly at the root of site-packages and a project defines a package src/foo. If you create src/lib.so, there will never be a match because the directory traversal starts at src/foo rather than src. In that case you must do either:
     
    build_data['force_include']['src/lib.so'] = 'src/lib.so'

    While user-facing TOML options are hyphenated, build data fields should be named with underscores to allow plugins to use them as valid Python identifiers.
     
     
    Notes
     
    In some cases it may be necessary to use force_include rather than artifacts. For example, say that you want to install a lib.so directly at the root of site-packages and a project defines a package src/foo. If you create src/lib.so, there will never be a match because the directory traversal starts at src/foo rather than src. In that case you must do either:
     
    build_data['force_include']['src/lib.so'] = 'src/lib.so'
 
     
    or
     
    build_data['force_include']['/absolute/path/to/src/lib.so'] = 'src/lib.so'

    Build behavior
     
    If any scripts are defined then each one will be built (limited by the scripts option). Otherwise, a single executable will be built based on the project name assuming there is an equivalently named module with a __main__.py file.
     
    Every executable will be built inside an app directory in the output directory.
     
    If the CARGO environment variable is set then that path will be used as the executable for performing builds.
     
    If the CARGO_BUILD_TARGET environment variable is set then its value will be appended to the file name stems.
     
    If the PYAPP_REPO environment variable is set then a local build will be performed inside that directory rather than installing from crates.io. Note that this is required if the CARGO environment variable refers to cross.

Builds are configured using the tool.hatch.build table. Every target is defined by a section within tool.hatch.build.targets, for example:
  pyproject.toml hatch.toml 
[tool.hatch.build.targets.sdist]\nexclude = [\n  \"/.github\",\n  \"/docs\",\n]\n\n[tool.hatch.build.targets.wheel]\npackages = [\"src/foo\"]\n

"},{"location":"build/#building","title":"Building","text":"
Invoking the build command without any arguments will build the sdist and wheel targets:
 
$ hatch build\n[sdist]\ndist/hatch_demo-1rc0.tar.gz\n\n[wheel]\ndist/hatch_demo-1rc0-py3-none-any.whl\n
 
To only build specific targets, use the -t/--target option:
 
$ hatch build -t wheel\n[wheel]\ndist/hatch_demo-1rc0-py3-none-any.whl\n
 
If the target supports multiple versions, you can specify the exact versions to build by appending a colon followed by the desired versions separated by commas:
 
$ hatch -v build -t wheel:standard\n[wheel]\nBuilding `wheel` version `standard`\ndist/hatch_demo-1rc0-py3-none-any.whl\n
"},{"location":"build/#packaging-ecosystem","title":"Packaging ecosystem","text":"
Hatch complies with modern Python packaging specs and therefore your projects can be used by other tools with Hatch serving as just the build backend.
 
So you could use tox as an alternative to Hatch's environment management, or cibuildwheel to distribute packages for every platform, and they both will transparently use Hatch without any extra modification.
"},{"location":"environment/","title":"Environments","text":"
Environments are designed to allow for isolated workspaces for testing, building documentation, or anything else projects need.
 
Unless an environment is chosen explicitly, Hatch will use the default environment.
 
Tip
 
For a more comprehensive walk-through, see the Basic usage tutorial.
"},{"location":"environment/#creation","title":"Creation","text":"
You can create environments by using the env create command. Let's enter the directory of the project we created in the setup phase:
 
$ hatch env create\nCreating environment: default\nInstalling project in development mode\nSyncing dependencies\n
 
Tip
 
You never need to manually create environments as spawning a shell or running commands within one will automatically trigger creation.
"},{"location":"environment/#entering-environments","title":"Entering environments","text":"
You can spawn a shell within an environment by using the shell command.
 
$ hatch shell\n(hatch-demo) $\n
 
Now confirm the project has been installed:
 
(hatch-demo) $ pip show hatch-demo\nName: hatch-demo\nVersion: 0.0.1\n...\n
 
Finally, see where your environment's Python is located:
 
(hatch-demo) $ python -c \"import sys;print(sys.executable)\"\n...\n
 
You can type exit to leave the environment.
"},{"location":"environment/#command-execution","title":"Command execution","text":"
The run command allows you to execute commands in an environment as if you had already entered it. For example, running the following command will output the same path as before:
 
hatch run python -c \"import sys;print(sys.executable)\"\n
 
Tip
 
Be sure to check out how to define scripts for your project.
"},{"location":"environment/#dependencies","title":"Dependencies","text":"
Hatch ensures that environments are always compatible with the currently defined project dependencies (if installed and in dev mode) and environment dependencies.
 
To add cowsay as a dependency, open pyproject.toml and add it to the dependencies array:
  pyproject.toml 
[project]\n...\ndependencies = [\n  \"cowsay\"\n]\n
 
This dependency will be installed the next time you spawn a shell or run a command. For example:
 
$ hatch run cowsay -t \"Hello, world!\"\nSyncing dependencies\n  _____________\n| Hello, world! |\n  =============\n             \\\n              \\\n                ^__^\n                (oo)\\_______\n                (__)\\       )\\/\\\n                    ||----w |\n                    ||     ||\n
 
Note
 
The Syncing dependencies status will display temporarily when Hatch updates environments in response to any dependency changes that you make.
"},{"location":"environment/#selection","title":"Selection","text":"
You can select which environment to enter or run commands in by using the -e/--env root option or by setting the HATCH_ENV environment variable.
 
The run command allows for more explicit selection by prepending <ENV_NAME>: to commands. For example, if you had the following configuration:
  pyproject.toml hatch.toml 
[tool.hatch.envs.docs]\ndependencies = [\n  \"mkdocs\"\n]\n[tool.hatch.envs.docs.scripts]\nbuild = \"mkdocs build --clean --strict\"\nserve = \"mkdocs serve --dev-addr localhost:8000\"\n
 
[envs.docs]\ndependencies = [\n  \"mkdocs\"\n]\n[envs.docs.scripts]\nbuild = \"mkdocs build --clean --strict\"\nserve = \"mkdocs serve --dev-addr localhost:8000\"\n
 
you could then serve your documentation by running:
 
hatch run docs:serve\n
 
Tip
 
If you've already entered an environment, commands will target it by default.
"},{"location":"environment/#matrix","title":"Matrix","text":"
Every environment can define its own set of matrices:
  pyproject.toml hatch.toml 
[tool.hatch.envs.test]\ndependencies = [\n  \"pytest\"\n]\n\n[[tool.hatch.envs.test.matrix]]\npython = [\"3.10\", \"3.11\"]\nversion = [\"42\", \"3.14\"]\n\n[[tool.hatch.envs.test.matrix]]\npython = [\"3.11\", \"3.12\"]\nversion = [\"9000\"]\nfeature = [\"foo\", \"bar\"]\n
 
[envs.test]\ndependencies = [\n  \"pytest\"\n]\n\n[[envs.test.matrix]]\npython = [\"3.10\", \"3.11\"]\nversion = [\"42\", \"3.14\"]\n\n[[envs.test.matrix]]\npython = [\"3.11\", \"3.12\"]\nversion = [\"9000\"]\nfeature = [\"foo\", \"bar\"]\n

When the version is not statically set, configuration is defined in the tool.hatch.version table. The source option determines the source to use for retrieving and updating the version. The regex source is used by default.
 
The regex source requires an option path that represents a relative path to a file containing the project's version:
  pyproject.toml hatch.toml 
[tool.hatch.version]\npath = \"src/hatch_demo/__about__.py\"\n
 
[version]\npath = \"src/hatch_demo/__about__.py\"\n
 
The default pattern looks for a variable named __version__ or VERSION that is set to a string containing the version, optionally prefixed with the lowercase letter v.
 
If this doesn't reflect how you store the version, you can define a different regular expression using the pattern option:
  pyproject.toml hatch.toml 
[tool.hatch.version]\npath = \"pkg/__init__.py\"\npattern = \"BUILD = 'b(?P<version>[^']+)'\"\n
 
[version]\npath = \"pkg/__init__.py\"\npattern = \"BUILD = 'b(?P<version>[^']+)'\"\n

You can update the version like so:
 
$ hatch version \"0.1.0\"\nOld: 0.0.1\nNew: 0.1.0\n
 
The scheme option determines the scheme to use for parsing both the existing and new versions. The standard scheme is used by default, which is based on PEP 440.
 
Rather than setting the version explicitly, you can select the name of a segment used to increment the version:
 
$ hatch version minor\nOld: 0.1.0\nNew: 0.2.0\n
 
You can chain multiple segment updates with a comma. For example, if you wanted to release a preview of your project's first major version, you could do:

The high level value proposition of Hatch is that if one adopts all functionality then many other tools become unnecessary since there is support for everything one might require. Further, if one chooses to use only specific features then there are still benefits compared to alternatives.
"},{"location":"why/#build-backend","title":"Build backend","text":"
Hatchling, the build backend sister project, has many benefits compared to setuptools. Here we only compare setuptools as that is the one most people are familiar with.
 
     
  • Better defaults: The default behavior for setuptools is often not desirable for the average user.
       
    • For source distributions, setuptools has a custom enumeration of files that get included and excluded by default. Hatchling takes the defaults from your version control system such as Git's .gitignore file.
      •  
    • For wheels, setuptools attempts to find every directory that looks like a Python package. This is often undesirable as you might ship files to the end-user unintentionally such as test or tooling directories. Hatchling defaults to very specific inclusion based on the project name and errors if no heuristic is satisfied.
      •  
     
    •  
  • Ease of configurability: Hatchling was designed based on a history of significant challenges when configuring setuptools.
       
    • Hatchling uses the same glob pattern syntax as Git itself for every option which is what most users are familiar with. On the other hand, setuptools uses shell-style glob patterns for source distributions while wheels use a mix of shell-style globs and Python package syntax.
      •  
    • Configuring what gets included in source distributions requires a separate MANIFEST.in file. The custom syntax and directives must be learned and it is difficult knowing which options in the main files like setup.py influence the behavior and under what conditions. For Hatchling, everything gets configured in a single file under dedicated sections for specific targets like [tool.hatch.build.targets.wheel].
      •  
    • By default, non-Python files are excluded from wheels. Including such files requires usually verbose rules for every nested package directory. Hatchling makes no such distinction between file types and acts more like a general build system one might already be familiar with.
      •  
     
    •  
  • Editable installations: The default behavior of Hatchling allows for proper static analysis by external tools such as IDEs. With setuptools, you must provide additional configuration which means that by default, for example, you would not get autocompletion in Visual Studio Code. This is marked as a legacy feature and may in fact be removed in future versions of setuptools.
    •  
  • Reproducibility: Hatchling builds reproducible wheels and source distributions by default. setuptools does not support this for source distributions and there is no guarantee that wheels are reproducible.
    •  
  • Extensibility: Although it is possible to extend setuptools, the API is quite low level. Hatchling has the concept of plugins that are separated into discrete types and only expose what is necessary, leading to an easier developer experience.
    •  
 
Why not?:
 
If building extension modules is required then it is recommended that you continue using setuptools, or even other backends that specialize in interfacing with compilers.
"},{"location":"why/#environment-management","title":"Environment management","text":"
Here we compare to both tox and nox. At a high level, there are a few common advantages:
 
     
  • Python management: Hatch is able to automatically download Python distributions on the fly when specific versions that environments request cannot be found. The alternatives will raise an error, with the option to ignore unknown distributions.
    •  
  •  
    Philosophy: In the alternatives, environments are for the most part treated as executable units where a dependency set is associated with an action. If you are familiar with container ecosystems, this would be like defining a CMD at the end of a Dockerfile but without the ability to change the action at runtime. This involves significant wasted disk space usually because one often requires slight modifications to the actions and therefore will define entirely different environments inherited from a base config just to perform different logic. Additionally, this can be confusing to users not just configuration-wise but also for execution of the different environments.
     
    In Hatch, environments are treated as isolated areas where you can execute arbitrary commands at runtime. For example, you can define a single test environment with named scripts that runs unit vs non-unit tests, each command being potentially very long but named however you wish so you get to control the interface. Since environments are treated as places where work is performed, you can also spawn a shell into any which will execute a subprocess that automatically drops into your shell of choice. Your shell will be configured appropriately like python on PATH being updated and the prompt being changed to reflect the chosen environment.
     
    •  
  •  
    Configuration:
     
       
    • tox only supports INI configuration and if one desires putting that in the standard pyproject.toml file then it must be a multi-line string containing the INI config which would preclude syntax highlighting. Hatch allows for TOML-based config just like most other tools in the Python ecosystem.
      •  
    • nox config is defined in Python which often leads to increased verbosity and makes it challenging to onboard folks compared to a standardized format with known behaviors.
      •  
     
    •  
  • Extensibility:
       
    • tox allows for extending most aspects of its functionality however the API is so low-level and attached to internals that creating plugins may be challenging. For example, here is a tox plugin that was migrated to an equivalent Hatch environment collector plugin.
      •  
    • nox is configured with Python so for the local project you can do whatever you want, however there is no concept of third-party plugins per se. To achieve that, you must usually use a package that wraps nox and use that package's imports instead (example).
      •  
     
    •  
 
Why not?:
 
If you are using nox and you wish to migrate, and for some reason you notify sessions, then migration wouldn't be a straight translation but rather you might have to redesign that conditional step.
"},{"location":"why/#python-management","title":"Python management","text":"
Here we compare Python management to that of pyenv.
 
     
  • Cross-platform: Hatch allows for the same experience no matter the system whereas pyenv does not support Windows so you must use an entirely different project that tries to emulate the functionality.
    •  
  • No build dependencies: Hatch guarantees that every available distribution is prebuilt whereas the alternative requires one to maintain a precise build environment which differs by platform and potentially Python version. Another benefit to this is extremely fast installations since the distributions are simply downloaded and unpacked.
    •  
  • Optimized by default: The CPython distributions are built with profile guided optimization and link-time optimization, resulting in a 10-30% performance improvement depending on the workload. These distributions have seen wide adoption throughout the industry and are even used by the build system Bazel.
    •  
  • Simplicity: Hatch treats Python installations as just another directory that one would add to PATH. It can do this for you or you can manage PATH yourself, even allowing for custom install locations. On the other hand, pyenv operates by adding shims which then act as wrappers around the actual underlying binaries. This has many unfortunate side effects:
       
    • It is incumbent upon the user to manage which specific Python comes first via the CLI, switch when necessary, and/or have a mental model of which versions are exposed globally and locally per-project. This can become confusing quite quickly. When working with Hatch, your global Python installations are only important insofar as they are on PATH somewhere since environments do not use them directly but rather create virtual environments from them, always using a version that is compatible with your project.
      •  
    • Configuration is required for each shell to properly set up pyenv on start, leading to inconsistencies when running processes that do not spawn a shell.
      •  
    • Debugging issues with Python search paths can be extremely difficult, especially for users of software. If you or users have ever ran into an issue where code was being executed that you did not anticipate, the issue is almost always pyenv influencing the python on PATH.
      •  
     
    •  
 
Why not?:
 
Currently, Hatch does not allow for the installation of specific patch release versions but rather only uses minor release granularity that tracks the latest patch release. If specific patch releases are important to you then it is best to use an alternative installation mechanism.

The package installer UV, brought to you by the same folks behind Ruff, is now supported. In any environment, you can set the installer option to uv to use UV in place of virtualenv & pip for virtual environment creation and dependency management, respectively. This often results in a significant performance benefit.
 
For example, if you wanted to enable this functionality for the default environment, you could set the following:
  pyproject.toml hatch.toml 
[tool.hatch.envs.default]\ninstaller = \"uv\"\n
 
[envs.default]\ninstaller = \"uv\"\n
 
Semi-internal environments like those used for testing and static analysis have this enabled by default.

Hatch v1.6.0 brings improvements to build environments, better handling of dynamic metadata, and support for tools like Visual Studio Code.
"},{"location":"blog/2022/10/08/hatch-v160/#build-environments","title":"Build environments","text":"
Originally, the environment interface method for providing builder sub-environments was intended to be used in conjunction with some cleanup logic in order to provide a fresh setup every time. However, this is unnecessary in practice because build dependencies rarely change.
 
Without caching, repeat build environment use is slow which affects the following scenarios:
 
     
  • the build command
    •  
  • commands that read project metadata, like dep hash, if any fields are set dynamically
    •  
 
Now a new environment interface method build_environment_exists is used by Hatch to determine whether or not it has already been created, for implementations that have a caching mechanism.
 
The virtual environment type now uses this method to cache build environments.
"},{"location":"blog/2022/10/08/hatch-v160/#project-metadata","title":"Project metadata","text":"
Dynamically defined metadata is now supported everywhere, thanks to the new caching of virtual build environments.
 
A project metadata command is introduced that displays the fully resolved metadata. The output format is JSON unless a field is specified as an argument.
 
For example, if you checkout a project that is built by Hatch, like FastAPI, and run:
 
hatch project metadata readme\n
 
only the readme text will be displayed. If the content is in Markdown, then Rich will render it directly in your terminal:
 
"},{"location":"blog/2022/10/08/hatch-v160/#virtual-environment-location","title":"Virtual environment location","text":"
The virtual environment type now uses a flat layout for storage in the configured virtual environment directory if the directory resides somewhere within the project root or if it is set to a .virtualenvs directory within the user's home directory.
 
For example, if you define the following Hatch configuration:
  config.toml 
[dirs.env]\nvirtual = \".hatch\"\n
 
and the following matrix:
  pyproject.toml hatch.toml 
[[tool.hatch.envs.test.matrix]]\npython = [\"3.7\", \"3.8\", \"3.9\", \"3.10\", \"3.11\"]\n
 
[[envs.test.matrix]]\npython = [\"3.7\", \"3.8\", \"3.9\", \"3.10\", \"3.11\"]\n
 
then locating environments with the following command:
 
hatch env find test\n
 
will show that the general directory structure is:
 
.hatch\n\u251c\u2500\u2500 test.py3.7\n\u251c\u2500\u2500 test.py3.8\n\u251c\u2500\u2500 test.py3.9\n\u251c\u2500\u2500 test.py3.10\n\u2514\u2500\u2500 test.py3.11\n
 
This flat structure is required for detection of virtual environments by tools like Visual Studio Code and PyCharm.
 
Additionally, the virtual environment type now supports a path option to specify an explicit path that all inherited environments will share, such as the common .venv.

"},{"location":"blog/2023/12/11/hatch-v180/#installation-made-easy","title":"Installation made easy","text":"
One thing that has been a perpetual problem for Hatch and other Python applications is that Python itself is a dependency. You, and more importantly your users, need to in some way get Python before your software can even be used. The recommended way to go about that is platform-dependent and even differs based on your target audience. I viewed this as a central UX problem for Hatch and so severe that I took a bit of a hiatus to solve it.
 
Luckily, I have to my satisfaction solved this problem in the form of PyApp. It is a runtime installer for Python projects written in Rust. Apps are distributed as standalone executables as users have come to expect and bootstrapping occurs upon the first invocation. Here is an example of what you would see the first time you run a binary from this release:
 
 
Now that we have binaries, creating installers for different platforms becomes trivial. Starting with this release not only are binaries available for every platform but also we have installers for Windows and macOS. The installer for macOS is signed using a certificate from the same account used to sign the official distributions from https://www.python.org, so users will not get any security pop-ups. Shout out to @ewdurbin for their extreme generosity in setting up multiple certificates in their free time!
 
These installers and binaries are now the recommended way to install and update Hatch. These binaries have built-in management so you can update to the latest version by running hatch self update.
 
Windows signing
 
In future we will sign the installers for Windows but I did not have time to look into how that works. macOS signing took way longer than I anticipated 
"},{"location":"blog/2023/12/11/hatch-v180/#python-management","title":"Python management","text":"
For a long time I and other users have desired that Hatch gain the ability to manage Python distributions. In my mind this was always blocked on a better installation experience because there was sort of a chicken-or-egg problem where you want a Python manager but you first need Python. No longer is that the case!
 
The new python command group allows for easy installation of various distributions to arbitrary locations which are then added to your PATH by default. Hatch supports CPython and PyPy distributions:
 
"},{"location":"blog/2023/12/11/hatch-v180/#virtual-environment-python-resolution","title":"Virtual environment Python resolution","text":"
The virtual environment type is now far more intelligent when resolving the parent distribution to use and guarantees that, when no specific version is requested, the resolved distribution will always be compatible with the project.
 
Additionally, when a requested version cannot be found on PATH it will automatically be downloaded and managed internally.
"},{"location":"blog/2023/12/11/hatch-v180/#static-analysis","title":"Static analysis","text":"
There is a new fmt command, backed entirely by Ruff, that checks and fixes your code for formatting and linting issues.
 
Starting with this release, Hatch maintains default settings that are guaranteed to be up-to-date and represent best practices for programming in modern Python. The idea is to provide defaults that are so broadly applicable that the majority of users will maintain little if any of their own overrides.
 
The default behavior is internal management of settings to provide an OOTB experience that works. It is recommended however that you persist the default config file in version control so that other tools like IDEs can utilize your full configuration.
 
Since Ruff is now provided as a built-in feature, new project templates no longer have such configuration and are much less verbose.

Building projects that do not use Hatchling as a backend is now supported and such builds are managed with the standard build tool.
 
The bridge between Hatch and the Hatchling CLI has been removed. Previously, the builder would send serialized messages to Hatch that would contain the desired content and style for each line of output. This was done in an effort to allow builder and build hook plugins to output pretty messages without actually requiring a dependency like Rich. A problem that arises with this is that builders that invoke subprocesses will not display ANSI codes as one might expect and will lose out on the interactive experience of such invocations, like the built-in binary builder plugin calling cargo build. So now everything is simpler at the expense of no colored output without manual logic, or adding a dependency if you're a third-party plugin.

Spawning a shell or running commands within environments always first checks that your project's dependencies are satisfied and if not synchronizes the environment with what is defined. Previously, this had the potential to be quite slow for projects that have many dependencies.

  1.  
    A significant amount of my free time (and some at work) will be devoted to introducing lock file functionality in Hatch and trying to get whatever that happens to be standardized.
     
    I met with @brettcannon about his thoughts post-PEP 665 and about mousebender. I also met with the prefix.dev team about rip and was fortunate enough to be shown a demo before its official announcement.
     
    At the moment, the two options I see are to either go all in and contribute to mousebender or rely on the Prefix folks and use rip. The latter has the benefit of potentially supporting Conda as a side effect with the downside of being quite new with the spec firmly out of our control. The former has the benefit of being able to easily gain institutional support from the Python packaging team and each of our employers with the downside being a significant amount of work needing to be done.
     
    2.  
  2.  
    When @henryiii is able to get some free time away from teaching I plan to work with him once again and push very hard for the Python build ecosystem to adopt the extensionlib approach.
     
    I am of the opinion that the Python community has not fully completed the expressed outcome of PEP 517 in that build backends are still (for the most part) reliant on setuptools for building non-Python code bases.
     
    Basically, there are components that interact with compilers to produce extension modules and components that pack files into an archive which we call a build backend. These are two distinct pieces of functionality and my view is that there should be an API that allows backends to consume extension module builders to find out where things got created and where they should be shipped inside archives.
     
    In this hypothetical future any build backend would be able to trigger the building of extension modules based on user configuration.

    [tool.ruff.format]\npreview = true\nquote-style = \"single\"\n\n[tool.ruff.lint]\npreview = true\nextend-select = [\"C901\"]\n\n[tool.ruff.lint.extend-per-file-ignores]\n\"docs/.hooks/*\" = [\"INP001\", \"T201\"]\n\n[tool.ruff.lint.isort]\nknown-first-party = [\"foo\", \"bar\"]\n
     
    [format]\npreview = true\nquote-style = \"single\"\n\n[lint]\npreview = true\nextend-select = [\"C901\"]\n\n[lint.extend-per-file-ignores]\n\"docs/.hooks/*\" = [\"INP001\", \"T201\"]\n\n[lint.isort]\nknown-first-party = [\"foo\", \"bar\"]\n
     
    Note
     
    When not persisting config, there is no need to explicitly extend the defaults as Hatch automatically handles that.
    "},{"location":"config/internal/static-analysis/#persistent-config","title":"Persistent config","text":"
    If you want to store the default configuration in the project, set an explicit path like so:
      pyproject.toml hatch.toml 
    [tool.hatch.envs.hatch-static-analysis]\nconfig-path = \"ruff_defaults.toml\"\n
     
    [envs.hatch-static-analysis]\nconfig-path = \"ruff_defaults.toml\"\n
     
    Then instruct Ruff to consider your configuration as an extension of the default file:
      pyproject.toml ruff.toml 
    [tool.ruff]\nextend = \"ruff_defaults.toml\"\n
     
    extend = \"ruff_defaults.toml\"\n
     
    Anytime you wish to update the defaults (such as when upgrading Hatch), you must run the fmt command once with the --sync flag e.g.:
     
    hatch fmt --check --sync\n
     
    Tip
     
    This is the recommended approach since it allows other tools like IDEs to use the default configuration.
    "},{"location":"config/internal/static-analysis/#no-config","title":"No config","text":"
    If you don't want Hatch to use any of its default configuration and rely entirely on yours, set the path to anything and then simply don't extend in your Ruff config:
      pyproject.toml hatch.toml 
    [tool.hatch.envs.hatch-static-analysis]\nconfig-path = \"none\"\n
     
    [envs.hatch-static-analysis]\nconfig-path = \"none\"\n

    You can fully alter the behavior of the environment used by the fmt command. See the how-to for a detailed example.

    Pin the particular version of Ruff by explicitly defining the environment dependencies:
      pyproject.toml hatch.toml 
    [tool.hatch.envs.hatch-static-analysis]\ndependencies = [\"ruff==X.Y.Z\"]\n
     
    [envs.hatch-static-analysis]\ndependencies = [\"ruff==X.Y.Z\"]\n
    "},{"location":"config/internal/static-analysis/#scripts","title":"Scripts","text":"
    If you want to change the default commands that are executed, you can override the scripts. The following four scripts must be defined:
      pyproject.toml hatch.toml 
    [tool.hatch.envs.hatch-static-analysis.scripts]\nformat-check = \"...\"\nformat-fix = \"...\"\nlint-check = \"...\"\nlint-fix = \"...\"\n
     
    [envs.hatch-static-analysis.scripts]\nformat-check = \"...\"\nformat-fix = \"...\"\nlint-check = \"...\"\nlint-fix = \"...\"\n
     
    The format-* scripts correspond to the --formatter/-f flag while the lint-* scripts correspond to the --linter/-l flag. The *-fix scripts run by default while the *-check scripts correspond to the --check flag.

    If you have project metadata that is not appropriate for static entry into pyproject.toml you will need to provide a custom metadata hook to apply such data during builds.
     
    Alternatives
     
    Dynamic metadata is a way to have a single source of truth that will be available at build time and at run time. Another way to achieve that is to enter the build data statically and then look up the same information dynamically in the program or package, using importlib.metadata.
     
    If the version field is the only metadata of concern, Hatchling provides a few built-in ways such as the regex version source and also third-party plugins. The approach here will also work, but is more complex.
    "},{"location":"how-to/config/dynamic-metadata/#update-project-metadata","title":"Update project metadata","text":"
    Change the [project] section of pyproject.toml:
     
       
    1. Define the dynamic field as an array of all the fields you will set dynamically e.g. dynamic = [\"version\", \"license\", \"authors\", \"maintainers\"]
      2.  
    2. If any of those fields have static definitions in pyproject.toml, delete those definitions. It is verboten to define a field statically and dynamically.
      3.  
     
    Add a section to trigger loading of dynamic metadata plugins: [tool.hatch.metadata.hooks.custom]. Use exactly that name, regardless of the name of the class you will use or its PLUGIN_NAME. There doesn't need to be anything in the section.
     
    If your plugin requires additional third-party packages to do its work, add them to the requires array in the [build-system] section of pyproject.toml.

    The dynamic lookup must happen in a custom plugin that you write. The default expectation is that it is in a hatch_build.py file at the root of the project. Subclass MetadataHookInterface and implement update(); for example, here's plugin that reads metadata from a JSON file:
      hatch_build.py 
    import json\nimport os\n\nfrom hatchling.metadata.plugin.interface import MetadataHookInterface\n\n\nclass JSONMetaDataHook(MetadataHookInterface):\n    def update(self, metadata):\n        src_file = os.path.join(self.root, \"gnumeric\", \".constants.json\")\n        with open(src_file) as src:\n            constants = json.load(src)\n            metadata[\"version\"] = constants[\"__version__\"]\n            metadata[\"license\"] = constants[\"__license__\"]\n            metadata[\"authors\"] = [\n                {\"name\": constants[\"__author__\"], \"email\": constants[\"__author_email__\"]},\n            ]\n

    2. Do your operations inside the update method.

    The virtual environment type by default uses virtualenv for virtual environment creation and pip to install dependencies. You can speed up environment creation and dependency resolution by using UV instead of both of those tools.
     
    caveat
     
    UV is under active development and may not work for all dependencies.
     
    To do so, set the installer option to uv. For example, if you wanted to enable this functionality for the default environment, you could set the following:
      pyproject.toml hatch.toml 
    [tool.hatch.envs.default]\ninstaller = \"uv\"\n
     
    [envs.default]\ninstaller = \"uv\"\n

    If you have scripts or commands that call pip, it may be useful to alias the uv pip command to pip so that you can use the same commands for both methods of configuration and retain your muscle memory. The following is an example of a matrix that conditionally enables UV and sets the alias:
      pyproject.toml hatch.toml 
    [[tool.hatch.envs.example.matrix]]\ntool = [\"uv\", \"pip\"]\n\n[tool.hatch.envs.example.overrides]\nmatrix.tool.installer = { value = \"{matrix:tool}\" }\nmatrix.tool.scripts = [\n  { key = \"pip\", value = \"{env:HATCH_UV} pip {args}\", if = [\"uv\"] },\n]\n

    Another common use case is to expose UV to all test environments. In this case, you often wouldn't want to modify the scripts mapping directly but rather add an extra script:

     Setting up PATH 
    If you installed Hatch with pipx rather than system-wide, you might need to add $HOME/.local/bin to your PATH environment variable for your graphical session, not just your terminal. Check like this:

    The issue with this is that after the first test session, the project will be forever cached by pip based on the file path. Therefore, subsequent tests runs will never use updated code.
     
    To invalidate the cache, copy your code to a new path for every test session:
     
    import shutil\nfrom pathlib import Path\nfrom tempfile import TemporaryDirectory\n\nimport pytest\n\n\n@pytest.fixture(scope='session')\ndef plugin_dir():\n    with TemporaryDirectory() as d:\n        directory = Path(d, 'plugin')\n        shutil.copytree(\n            Path.cwd(), directory, ignore=shutil.ignore_patterns('.git')\n        )\n\n        yield directory.resolve()\n\n\n@pytest.fixture\ndef new_project(tmp_path, plugin_dir):\n    project_dir = tmp_path / 'my-app'\n    project_dir.mkdir()\n\n    project_file = project_dir / 'pyproject.toml'\n    project_file.write_text(\n        f\"\"\"\\\n[build-system]\nrequires = [\"hatchling\", \"hatch-plugin-name @ {plugin_dir.as_uri()}\"]\nbuild-backend = \"hatchling.build\"\n\n[project]\nname = \"my-app\"\nversion = \"0.1.0\"\n\"\"\",\n        encoding='utf-8',\n    )\n    ...\n

    The top-level fields are:
     
       
    • dependencies: A list of strings that specifies the runtime dependencies of the script. Each entry must be a valid dependency specifier.
      •  
    • requires-python: A string that specifies the Python version(s) with which the script is compatible. The value of this field must be a valid version specifier.
      •  
     
    The following is an example of Python script with a valid metadata block:
      script.py 
    # /// script\n# requires-python = \">=3.11\"\n# dependencies = [\n#   \"httpx\",\n#   \"rich\",\n# ]\n# ///\n\nimport httpx\nfrom rich.pretty import pprint\n\nresp = httpx.get(\"https://peps.python.org/api/peps.json\")\ndata = resp.json()\npprint([(k, v[\"title\"]) for k, v in data.items()][:10])\n
     
    Run it directly:
     
    $ hatch run /path/to/script.py\nCreating environment: SyB4bPbL\nChecking dependencies\nSyncing dependencies\n[\n\u2502   ('1', 'PEP Purpose and Guidelines'),\n\u2502   ('2', 'Procedure for Adding New Modules'),\n\u2502   ('3', 'Guidelines for Handling Bug Reports'),\n\u2502   ('4', 'Deprecation of Standard Modules'),\n\u2502   ('5', 'Guidelines for Language Evolution'),\n\u2502   ('6', 'Bug Fix Releases'),\n\u2502   ('7', 'Style Guide for C Code'),\n\u2502   ('8', 'Style Guide for Python Code'),\n\u2502   ('9', 'Sample Plaintext PEP Template'),\n\u2502   ('10', 'Voting Guidelines')\n]\n

    You may use the [tool.hatch] table directly to control the script's environment. For example, if you wanted to disable UV (which is enabled by default for scripts), you could add the following:

    You can fully alter the static analysis performed by the fmt command by modifying the reserved environment named hatch-static-analysis. For example, you could define the following if you wanted to replace the default behavior with a mix of Black, isort and basic flake8:
      pyproject.toml hatch.toml 
    [tool.hatch.envs.hatch-static-analysis]\ndependencies = [\"black\", \"flake8\", \"isort\"]\n\n[tool.hatch.envs.hatch-static-analysis.scripts]\nformat-check = [\n  \"black --check --diff {args:.}\",\n  \"isort --check-only --diff {args:.}\",\n]\nformat-fix = [\n  \"isort {args:.}\",\n  \"black {args:.}\",\n]\nlint-check = \"flake8 {args:.}\"\nlint-fix = \"lint-check\"\n
     
    [envs.hatch-static-analysis]\ndependencies = [\"black\", \"flake8\", \"isort\"]\n\n[envs.hatch-static-analysis.scripts]\nformat-check = [\n  \"black --check --diff {args:.}\",\n  \"isort --check-only --diff {args:.}\",\n]\nformat-fix = [\n  \"isort {args:.}\",\n  \"black {args:.}\",\n]\nlint-check = \"flake8 {args:.}\"\nlint-fix = \"lint-check\"\n
     
    The format-* scripts correspond to the --formatter/-f flag while the lint-* scripts correspond to the --linter/-l flag. The *-fix scripts run by default while the *-check scripts correspond to the --check flag. Based on this example, the following shows how the various scripts influence behavior:

    Q: What is the risk of lock-in?
     
    A: Not much! Other than the plugin system, everything uses Python's established standards by default. Project metadata is based entirely on the standard, the build system is compatible with PEP 517/PEP 660, versioning uses the scheme specified by PEP 440, dependencies are defined with PEP 508 strings, and environments use virtualenv.
     
    Q: Must one use all features?
     
    A: No, all features are optional! You can use just the build system, publish wheels and source distributions that were built by other tools, only use the environment management, etc.
    "},{"location":"meta/faq/#libraries-vs-applications","title":"Libraries vs applications","text":"
    Q: Are workflows for both libraries and applications supported?
     
    A: Yes, mostly! Applications can utilize environment management just like libraries, and plugins can be used to build projects in arbitrary formats or publish artifacts to arbitrary destinations.
     
    The only caveat is that currently there is no support for re-creating an environment given a set of dependencies in a reproducible manner. Although a standard lock file format may be far off since PEP 665 was rejected, resolving capabilities are coming to pip. When that is stabilized, Hatch will add locking functionality and dedicated documentation for managing applications.

    All plugins provide registration hooks that return one or more classes that inherit from a particular type interface.

    Build hooks run for every selected version of build targets.
     
    The initialization stage occurs immediately before each build and the finalization stage occurs immediately after. Each stage has the opportunity to view or modify build data.
    "},{"location":"plugins/build-hook/reference/#build-data","title":"Build data","text":"
    Build data is a simple mapping whose contents can influence the behavior of builds. Which fields exist and are recognized depends on each build target.
     
    The following fields are always present and recognized by the build system itself:
     Field Type Description artifacts list[str] This is a list of extra artifact patterns and should generally only be appended to force_include dict[str, str] This is a mapping of extra forced inclusion paths, with this mapping taking precedence in case of conflicts build_hooks tuple[str, ...] This is an immutable sequence of the names of the configured build hooks and matches the order in which they run 
    Attention
     
    While user-facing TOML options are hyphenated, build data fields should be named with underscores to allow plugins to use them as valid Python identifiers.
    "},{"location":"plugins/build-hook/reference/#notes","title":"Notes","text":"
    In some cases it may be necessary to use force_include rather than artifacts. For example, say that you want to install a lib.so directly at the root of site-packages and a project defines a package src/foo. If you create src/lib.so, there will never be a match because the directory traversal starts at src/foo rather than src. In that case you must do either:
     
    build_data['force_include']['src/lib.so'] = 'src/lib.so'\n
     
    or
     
    build_data['force_include']['/absolute/path/to/src/lib.so'] = 'src/lib.so'\n

    Virtual environments necessarily require a parent installation of Python. The following rules determine how the parent is resolved.
     
    The Python choice is determined by the python option followed by the HATCH_PYTHON environment variable. If the choice is via the environment variable, then resolution stops and that path is used unconditionally.
     
    The resolvers will be based on the python-sources option and all resolved interpreters will ensure compatibility with the project's defined Python support.
     
    If a Python version has been chosen then each resolver will try to find an interpreter that satisfies that version.
     
    If no version has been chosen, then each resolver will try to find a version that matches the version of Python that Hatch is currently running on. If not found then each resolver will try to find the highest compatible version.
     
    Note
     
    Some external Python paths are considered unstable and are ignored during resolution. For example, if Hatch is installed via Homebrew then sys.executable will be ignored because the interpreter could change or be removed at any time.

    When resolution finds a match using an internally managed distribution and an update is available, the latest distribution will automatically be downloaded before environment creation.

    If you need to set linker environment variables like those starting with DYLD_ or LD_, any executable secured by System Integrity Protection that is invoked when running commands will not see those environment variable modifications as macOS strips those.
     
    Hatch interprets such commands as shell commands but deliberately ignores such paths to protected shells. This workaround suffices for the majority of use cases but there are 2 situations in which it may not:
     
       
    1. There are no unprotected sh, bash, zsh, nor fish executables found along PATH.
      2.  
    2. The desired executable is a project's script, and the location of environments contains spaces or is longer than 1241 characters. In this case pip and other installers will create such an entry point with a shebang pointing to /bin/sh (which is protected) to avoid shebang limitations. Rather than changing the location, you could invoke the script as e.g. python -m pytest (if the project supports that method of invocation by shipping a __main__.py).
      3.  
     
       
    1.  
      The shebang length limit is usually 127 but 3 characters surround the executable path: #!<EXE_PATH>\\n \u21a9

    If no environment options are selected, the test command will only run tests in the first defined environment that either already exists or is compatible. Additionally, the checking order will prioritize environments that define a version of Python that matches the interpreter that Hatch is running on.
     
    For example, if you overrode the default matrix as follows:
      pyproject.toml hatch.toml 
    [[tool.hatch.envs.hatch-test.matrix]]\npython = [\"3.12\", \"3.11\"]\n\n[[tool.hatch.envs.hatch-test.matrix]]\npython = [\"3.11\"]\nfeature = [\"foo\", \"bar\"]\n

    Since selecting the version of Python is a common use case, you can use the --python/-py option as a shorthand. For example, the previous commands could have been written as:

    Hatch complies with modern Python packaging specs and therefore your projects can be used by other tools with Hatch serving as just the build backend.
     
    So you could use tox as an alternative to Hatch's environment management, or cibuildwheel to distribute packages for every platform, and they both will transparently use Hatch without any extra modification.
    "},{"location":"environment/","title":"Environments","text":"
    Environments are designed to allow for isolated workspaces for testing, building documentation, or anything else projects need.
     
    Unless an environment is chosen explicitly, Hatch will use the default environment.
     
    Tip
     
    For a more comprehensive walk-through, see the Basic usage tutorial.

    Tip
     
    You never need to manually create environments as spawning a shell or running commands within one will automatically trigger creation.

    You can spawn a shell within an environment by using the shell command.

    Now confirm the project has been installed:
     
    (hatch-demo) $ pip show hatch-demo\nName: hatch-demo\nVersion: 0.0.1\n...\n
     
    Finally, see where your environment's Python is located:
     
    (hatch-demo) $ python -c \"import sys;print(sys.executable)\"\n...\n
     
    You can type exit to leave the environment.

    Tip
     
    Be sure to check out how to define scripts for your project.
    "},{"location":"environment/#dependencies","title":"Dependencies","text":"
    Hatch ensures that environments are always compatible with the currently defined project dependencies (if installed and in dev mode) and environment dependencies.
     
    To add cowsay as a dependency, open pyproject.toml and add it to the dependencies array:
      pyproject.toml 
    [project]\n...\ndependencies = [\n  \"cowsay\"\n]\n
     
    This dependency will be installed the next time you spawn a shell or run a command. For example:
     
    $ hatch run cowsay -t \"Hello, world!\"\nSyncing dependencies\n  _____________\n| Hello, world! |\n  =============\n             \\\n              \\\n                ^__^\n                (oo)\\_______\n                (__)\\       )\\/\\\n                    ||----w |\n                    ||     ||\n

    The Syncing dependencies status will display temporarily when Hatch updates environments in response to any dependency changes that you make.
    "},{"location":"environment/#selection","title":"Selection","text":"
    You can select which environment to enter or run commands in by using the -e/--env root option or by setting the HATCH_ENV environment variable.
     
    The run command allows for more explicit selection by prepending <ENV_NAME>: to commands. For example, if you had the following configuration:
      pyproject.toml hatch.toml 
    [tool.hatch.envs.docs]\ndependencies = [\n  \"mkdocs\"\n]\n[tool.hatch.envs.docs.scripts]\nbuild = \"mkdocs build --clean --strict\"\nserve = \"mkdocs serve --dev-addr localhost:8000\"\n

    you could then serve your documentation by running:
     
    hatch run docs:serve\n
     
    Tip
     
    If you've already entered an environment, commands will target it by default.

    Hatchling, the build backend sister project, has many benefits compared to setuptools. Here we only compare setuptools as that is the one most people are familiar with.
     
       
    • Better defaults: The default behavior for setuptools is often not desirable for the average user.
         
      • For source distributions, setuptools has a custom enumeration of files that get included and excluded by default. Hatchling takes the defaults from your version control system such as Git's .gitignore file.
        •  
      • For wheels, setuptools attempts to find every directory that looks like a Python package. This is often undesirable as you might ship files to the end-user unintentionally such as test or tooling directories. Hatchling defaults to very specific inclusion based on the project name and errors if no heuristic is satisfied.
        •  
       
      •  
    • Ease of configurability: Hatchling was designed based on a history of significant challenges when configuring setuptools.
         
      • Hatchling uses the same glob pattern syntax as Git itself for every option which is what most users are familiar with. On the other hand, setuptools uses shell-style glob patterns for source distributions while wheels use a mix of shell-style globs and Python package syntax.
        •  
      • Configuring what gets included in source distributions requires a separate MANIFEST.in file. The custom syntax and directives must be learned and it is difficult knowing which options in the main files like setup.py influence the behavior and under what conditions. For Hatchling, everything gets configured in a single file under dedicated sections for specific targets like [tool.hatch.build.targets.wheel].
        •  
      • By default, non-Python files are excluded from wheels. Including such files requires usually verbose rules for every nested package directory. Hatchling makes no such distinction between file types and acts more like a general build system one might already be familiar with.
        •  
       
      •  
    • Editable installations: The default behavior of Hatchling allows for proper static analysis by external tools such as IDEs. With setuptools, you must provide additional configuration which means that by default, for example, you would not get autocompletion in Visual Studio Code. This is marked as a legacy feature and may in fact be removed in future versions of setuptools.
      •  
    • Reproducibility: Hatchling builds reproducible wheels and source distributions by default. setuptools does not support this for source distributions and there is no guarantee that wheels are reproducible.
      •  
    • Extensibility: Although it is possible to extend setuptools, the API is quite low level. Hatchling has the concept of plugins that are separated into discrete types and only expose what is necessary, leading to an easier developer experience.
      •  
     
    Why not?:
     
    If building extension modules is required then it is recommended that you continue using setuptools, or even other backends that specialize in interfacing with compilers.
    "},{"location":"why/#environment-management","title":"Environment management","text":"
    Here we compare to both tox and nox. At a high level, there are a few common advantages:
     
       
    • Python management: Hatch is able to automatically download Python distributions on the fly when specific versions that environments request cannot be found. The alternatives will raise an error, with the option to ignore unknown distributions.
      •  
    •  
      Philosophy: In the alternatives, environments are for the most part treated as executable units where a dependency set is associated with an action. If you are familiar with container ecosystems, this would be like defining a CMD at the end of a Dockerfile but without the ability to change the action at runtime. This involves significant wasted disk space usually because one often requires slight modifications to the actions and therefore will define entirely different environments inherited from a base config just to perform different logic. Additionally, this can be confusing to users not just configuration-wise but also for execution of the different environments.
       
      In Hatch, environments are treated as isolated areas where you can execute arbitrary commands at runtime. For example, you can define a single test environment with named scripts that runs unit vs non-unit tests, each command being potentially very long but named however you wish so you get to control the interface. Since environments are treated as places where work is performed, you can also spawn a shell into any which will execute a subprocess that automatically drops into your shell of choice. Your shell will be configured appropriately like python on PATH being updated and the prompt being changed to reflect the chosen environment.
       
      •  
    •  
      Configuration:
       
         
      • tox only supports INI configuration and if one desires putting that in the standard pyproject.toml file then it must be a multi-line string containing the INI config which would preclude syntax highlighting. Hatch allows for TOML-based config just like most other tools in the Python ecosystem.
        •  
      • nox config is defined in Python which often leads to increased verbosity and makes it challenging to onboard folks compared to a standardized format with known behaviors.
        •  
       
      •  
    • Extensibility:
         
      • tox allows for extending most aspects of its functionality however the API is so low-level and attached to internals that creating plugins may be challenging. For example, here is a tox plugin that was migrated to an equivalent Hatch environment collector plugin.
        •  
      • nox is configured with Python so for the local project you can do whatever you want, however there is no concept of third-party plugins per se. To achieve that, you must usually use a package that wraps nox and use that package's imports instead (example).
        •  
       
      •  
     
    Why not?:
     
    If you are using nox and you wish to migrate, and for some reason you notify sessions, then migration wouldn't be a straight translation but rather you might have to redesign that conditional step.
    "},{"location":"why/#python-management","title":"Python management","text":"
    Here we compare Python management to that of pyenv.
     
       
    • Cross-platform: Hatch allows for the same experience no matter the system whereas pyenv does not support Windows so you must use an entirely different project that tries to emulate the functionality.
      •  
    • No build dependencies: Hatch guarantees that every available distribution is prebuilt whereas the alternative requires one to maintain a precise build environment which differs by platform and potentially Python version. Another benefit to this is extremely fast installations since the distributions are simply downloaded and unpacked.
      •  
    • Optimized by default: The CPython distributions are built with profile guided optimization and link-time optimization, resulting in a 10-30% performance improvement depending on the workload. These distributions have seen wide adoption throughout the industry and are even used by the build system Bazel.
      •  
    • Simplicity: Hatch treats Python installations as just another directory that one would add to PATH. It can do this for you or you can manage PATH yourself, even allowing for custom install locations. On the other hand, pyenv operates by adding shims which then act as wrappers around the actual underlying binaries. This has many unfortunate side effects:
         
      • It is incumbent upon the user to manage which specific Python comes first via the CLI, switch when necessary, and/or have a mental model of which versions are exposed globally and locally per-project. This can become confusing quite quickly. When working with Hatch, your global Python installations are only important insofar as they are on PATH somewhere since environments do not use them directly but rather create virtual environments from them, always using a version that is compatible with your project.
        •  
      • Configuration is required for each shell to properly set up pyenv on start, leading to inconsistencies when running processes that do not spawn a shell.
        •  
      • Debugging issues with Python search paths can be extremely difficult, especially for users of software. If you or users have ever ran into an issue where code was being executed that you did not anticipate, the issue is almost always pyenv influencing the python on PATH.
        •  
       
      •  
     
    Why not?:
     
    Currently, Hatch does not allow for the installation of specific patch release versions but rather only uses minor release granularity that tracks the latest patch release. If specific patch releases are important to you then it is best to use an alternative installation mechanism.

    Originally, the environment interface method for providing builder sub-environments was intended to be used in conjunction with some cleanup logic in order to provide a fresh setup every time. However, this is unnecessary in practice because build dependencies rarely change.
     
    Without caching, repeat build environment use is slow which affects the following scenarios:
     
       
    • the build command
      •  
    • commands that read project metadata, like dep hash, if any fields are set dynamically
      •  
     
    Now a new environment interface method build_environment_exists is used by Hatch to determine whether or not it has already been created, for implementations that have a caching mechanism.
     
    The virtual environment type now uses this method to cache build environments.
    "},{"location":"blog/2022/10/08/hatch-v160/#project-metadata","title":"Project metadata","text":"
    Dynamically defined metadata is now supported everywhere, thanks to the new caching of virtual build environments.
     
    A project metadata command is introduced that displays the fully resolved metadata. The output format is JSON unless a field is specified as an argument.
     
    For example, if you checkout a project that is built by Hatch, like FastAPI, and run:
     
    hatch project metadata readme\n
     
    only the readme text will be displayed. If the content is in Markdown, then Rich will render it directly in your terminal:
     
    "},{"location":"blog/2022/10/08/hatch-v160/#virtual-environment-location","title":"Virtual environment location","text":"
    The virtual environment type now uses a flat layout for storage in the configured virtual environment directory if the directory resides somewhere within the project root or if it is set to a .virtualenvs directory within the user's home directory.
     
    For example, if you define the following Hatch configuration:
      config.toml 
    [dirs.env]\nvirtual = \".hatch\"\n
     
    and the following matrix:
      pyproject.toml hatch.toml 
    [[tool.hatch.envs.test.matrix]]\npython = [\"3.7\", \"3.8\", \"3.9\", \"3.10\", \"3.11\"]\n
     
    [[envs.test.matrix]]\npython = [\"3.7\", \"3.8\", \"3.9\", \"3.10\", \"3.11\"]\n
     
    then locating environments with the following command:
     
    hatch env find test\n
     
    will show that the general directory structure is:
     
    .hatch\n\u251c\u2500\u2500 test.py3.7\n\u251c\u2500\u2500 test.py3.8\n\u251c\u2500\u2500 test.py3.9\n\u251c\u2500\u2500 test.py3.10\n\u2514\u2500\u2500 test.py3.11\n
     
    This flat structure is required for detection of virtual environments by tools like Visual Studio Code and PyCharm.

    One thing that has been a perpetual problem for Hatch and other Python applications is that Python itself is a dependency. You, and more importantly your users, need to in some way get Python before your software can even be used. The recommended way to go about that is platform-dependent and even differs based on your target audience. I viewed this as a central UX problem for Hatch and so severe that I took a bit of a hiatus to solve it.
     
    Luckily, I have to my satisfaction solved this problem in the form of PyApp. It is a runtime installer for Python projects written in Rust. Apps are distributed as standalone executables as users have come to expect and bootstrapping occurs upon the first invocation. Here is an example of what you would see the first time you run a binary from this release:
     
     
    Now that we have binaries, creating installers for different platforms becomes trivial. Starting with this release not only are binaries available for every platform but also we have installers for Windows and macOS. The installer for macOS is signed using a certificate from the same account used to sign the official distributions from https://www.python.org, so users will not get any security pop-ups. Shout out to @ewdurbin for their extreme generosity in setting up multiple certificates in their free time!
     
    These installers and binaries are now the recommended way to install and update Hatch. These binaries have built-in management so you can update to the latest version by running hatch self update.
     
    Windows signing
     
    In future we will sign the installers for Windows but I did not have time to look into how that works. macOS signing took way longer than I anticipated

    For a long time I and other users have desired that Hatch gain the ability to manage Python distributions. In my mind this was always blocked on a better installation experience because there was sort of a chicken-or-egg problem where you want a Python manager but you first need Python. No longer is that the case!
     
    The new python command group allows for easy installation of various distributions to arbitrary locations which are then added to your PATH by default. Hatch supports CPython and PyPy distributions:

    There is a new fmt command, backed entirely by Ruff, that checks and fixes your code for formatting and linting issues.
     
    Starting with this release, Hatch maintains default settings that are guaranteed to be up-to-date and represent best practices for programming in modern Python. The idea is to provide defaults that are so broadly applicable that the majority of users will maintain little if any of their own overrides.
     
    The default behavior is internal management of settings to provide an OOTB experience that works. It is recommended however that you persist the default config file in version control so that other tools like IDEs can utilize your full configuration.
     
    Since Ruff is now provided as a built-in feature, new project templates no longer have such configuration and are much less verbose.

    Building projects that do not use Hatchling as a backend is now supported and such builds are managed with the standard build tool.
     
    The bridge between Hatch and the Hatchling CLI has been removed. Previously, the builder would send serialized messages to Hatch that would contain the desired content and style for each line of output. This was done in an effort to allow builder and build hook plugins to output pretty messages without actually requiring a dependency like Rich. A problem that arises with this is that builders that invoke subprocesses will not display ANSI codes as one might expect and will lose out on the interactive experience of such invocations, like the built-in binary builder plugin calling cargo build. So now everything is simpler at the expense of no colored output without manual logic, or adding a dependency if you're a third-party plugin.

    1.  
      A significant amount of my free time (and some at work) will be devoted to introducing lock file functionality in Hatch and trying to get whatever that happens to be standardized.
       
      I met with @brettcannon about his thoughts post-PEP 665 and about mousebender. I also met with the prefix.dev team about rip and was fortunate enough to be shown a demo before its official announcement.
       
      At the moment, the two options I see are to either go all in and contribute to mousebender or rely on the Prefix folks and use rip. The latter has the benefit of potentially supporting Conda as a side effect with the downside of being quite new with the spec firmly out of our control. The former has the benefit of being able to easily gain institutional support from the Python packaging team and each of our employers with the downside being a significant amount of work needing to be done.
       
      2.  
    2.  
      When @henryiii is able to get some free time away from teaching I plan to work with him once again and push very hard for the Python build ecosystem to adopt the extensionlib approach.
       
      I am of the opinion that the Python community has not fully completed the expressed outcome of PEP 517 in that build backends are still (for the most part) reliant on setuptools for building non-Python code bases.
       
      Basically, there are components that interact with compilers to produce extension modules and components that pack files into an archive which we call a build backend. These are two distinct pieces of functionality and my view is that there should be an API that allows backends to consume extension module builders to find out where things got created and where they should be shipped inside archives.
       
      In this hypothetical future any build backend would be able to trigger the building of extension modules based on user configuration.

    The default version of Ruff has been increased to v0.1.8. This release brings formatting capabilities to docstrings and Hatch enables this by default with line length set to 80. This length was chosen as the default because it plays nicely with the rendering of the most popular themes for Python documentation, such as Material for MkDocs and Furo.
     
    Additionally, it is now possible for projects to pin to specific versions of Ruff for upgrading at a later time:

      [tool.hatch.build.targets.sdist]\nignore-vcs = true\n
       
      [build.targets.sdist]\nignore-vcs = true\n

      You can set the include and exclude options to select exactly which files will be shipped in each build, with exclude taking precedence. Every entry represents a Git-style glob pattern.
       
      For example, the following configuration:
        pyproject.toml hatch.toml 
      [tool.hatch.build.targets.sdist]\ninclude = [\n  \"pkg/*.py\",\n  \"/tests\",\n]\nexclude = [\n  \"*.json\",\n  \"pkg/_compat.py\",\n]\n

      "},{"location":"config/build/#artifacts","title":"Artifacts","text":"
      If you want to include files that are ignored by your VCS, such as those that might be created by build hooks, you can use the artifacts option. This option is semantically equivalent to include.
       
      Note that artifacts are not affected by the exclude option. Artifacts can be excluded by using more explicit paths or by using the ! negation operator. When using the ! operator, the negated pattern(s) must come after the more generic ones.

      You can use the only-include option to prevent directory traversal starting at the project root and only select specific relative paths to directories or files. Using this option ignores any defined include patterns.

      [tool.hatch.build.targets.sdist]\nonly-include = [\"pkg\", \"tests/unit\"]\n

      "},{"location":"config/build/#packages","title":"Packages","text":"
      The packages option is semantically equivalent to only-include (which takes precedence) except that the shipped path will be collapsed to only include the final component.
       
      So for example, if you want to ship a package foo that is stored in a directory src you would do:
        pyproject.toml hatch.toml 
      [tool.hatch.build.targets.wheel]\npackages = [\"src/foo\"]\n
       
      [build.targets.wheel]\npackages = [\"src/foo\"]\n

      The force-include option allows you to select specific files or directories from anywhere on the file system that should be included and map them to the desired relative distribution path.
       
      For example, if there was a directory alongside the project root named artifacts containing a file named lib.so and a file named lib.h in your home directory, you could ship both files in a pkg directory with the following configuration:
        pyproject.toml hatch.toml 
      [tool.hatch.build.targets.wheel.force-include]\n\"../artifacts\" = \"pkg\"\n\"~/lib.h\" = \"pkg/lib.h\"\n

      • Files must be mapped exactly to their desired paths, not to directories.

      If no file selection options are provided, then what gets included is determined by each build target.
      "},{"location":"config/build/#excluding-files-outside-packages","title":"Excluding files outside packages","text":"
      If you want to exclude non-artifact files that do not reside within a Python package, set only-packages to true:
        pyproject.toml hatch.toml 
      [tool.hatch.build.targets.wheel]\nonly-packages = true\n
       
      [build.targets.wheel]\nonly-packages = true\n
      "},{"location":"config/build/#rewriting-paths","title":"Rewriting paths","text":"
      You can rewrite relative paths to directories with the sources option. For example, the following configuration:
        pyproject.toml hatch.toml 
      [tool.hatch.build.targets.wheel.sources]\n\"src/foo\" = \"bar\"\n
       
      [build.targets.wheel.sources]\n\"src/foo\" = \"bar\"\n
       
      would distribute the file src/foo/file.ext as bar/file.ext.
       
      If you want to remove path prefixes entirely, rather than setting each to an empty string, you can define sources as an array:
        pyproject.toml hatch.toml 
      [tool.hatch.build.targets.wheel]\nsources = [\"src\"]\n
       
      [build.targets.wheel]\nsources = [\"src\"]\n
       
      If you want to add a prefix to paths, you can use an empty string. For example, the following configuration:
        pyproject.toml hatch.toml 
      [tool.hatch.build.targets.wheel.sources]\n\"\" = \"foo\"\n
       
      [build.targets.wheel.sources]\n\"\" = \"foo\"\n
       
      would distribute the file bar/file.ext as foo/bar/file.ext.

      If you want to change the default commands that are executed, you can override the scripts. The following four scripts must be defined:

      If you have project metadata that is not appropriate for static entry into pyproject.toml you will need to provide a custom metadata hook to apply such data during builds.
       
      Alternatives
       
      Dynamic metadata is a way to have a single source of truth that will be available at build time and at run time. Another way to achieve that is to enter the build data statically and then look up the same information dynamically in the program or package, using importlib.metadata.
       
      If the version field is the only metadata of concern, Hatchling provides a few built-in ways such as the regex version source and also third-party plugins. The approach here will also work, but is more complex.
      "},{"location":"how-to/config/dynamic-metadata/#update-project-metadata","title":"Update project metadata","text":"
      Change the [project] section of pyproject.toml:
       
         
      1. Define the dynamic field as an array of all the fields you will set dynamically e.g. dynamic = [\"version\", \"license\", \"authors\", \"maintainers\"]
        2.  
      2. If any of those fields have static definitions in pyproject.toml, delete those definitions. It is verboten to define a field statically and dynamically.
        3.  
       
      Add a section to trigger loading of dynamic metadata plugins: [tool.hatch.metadata.hooks.custom]. Use exactly that name, regardless of the name of the class you will use or its PLUGIN_NAME. There doesn't need to be anything in the section.
       
      If your plugin requires additional third-party packages to do its work, add them to the requires array in the [build-system] section of pyproject.toml.
      "},{"location":"how-to/config/dynamic-metadata/#implement-hook","title":"Implement hook","text":"
      The dynamic lookup must happen in a custom plugin that you write. The default expectation is that it is in a hatch_build.py file at the root of the project. Subclass MetadataHookInterface and implement update(); for example, here's plugin that reads metadata from a JSON file:
        hatch_build.py 
      import json\nimport os\n\nfrom hatchling.metadata.plugin.interface import MetadataHookInterface\n\n\nclass JSONMetaDataHook(MetadataHookInterface):\n    def update(self, metadata):\n        src_file = os.path.join(self.root, \"gnumeric\", \".constants.json\")\n        with open(src_file) as src:\n            constants = json.load(src)\n            metadata[\"version\"] = constants[\"__version__\"]\n            metadata[\"license\"] = constants[\"__license__\"]\n            metadata[\"authors\"] = [\n                {\"name\": constants[\"__author__\"], \"email\": constants[\"__author_email__\"]},\n            ]\n

      5. Use dict for TOML tables e.g. authors.

      The virtual environment type by default uses virtualenv for virtual environment creation and pip to install dependencies. You can speed up environment creation and dependency resolution by using UV instead of both of those tools.
       
      caveat
       
      UV is under active development and may not work for all dependencies.
       
      To do so, set the installer option to uv. For example, if you wanted to enable this functionality for the default environment, you could set the following:
        pyproject.toml hatch.toml 
      [tool.hatch.envs.default]\ninstaller = \"uv\"\n
       
      [envs.default]\ninstaller = \"uv\"\n

      All environments that enable UV will have the path to UV available as the HATCH_UV environment variable.
      "},{"location":"how-to/environment/select-installer/#configuring-the-version","title":"Configuring the version","text":"
      The UV that is shared by all environments uses a specific version range that is known to work with Hatch. If you want to use a different version, you can override the dependencies for the internal hatch-uv environment:

      If you want to manage UV yourself, you can expose it to Hatch by setting the HATCH_ENV_TYPE_VIRTUAL_UV_PATH environment variable which should be the absolute path to a UV binary for Hatch to use instead. This implicitly enables UV.

      If you have scripts or commands that call pip, it may be useful to alias the uv pip command to pip so that you can use the same commands for both methods of configuration and retain your muscle memory. The following is an example of a matrix that conditionally enables UV and sets the alias:
        pyproject.toml hatch.toml 
      [[tool.hatch.envs.example.matrix]]\ntool = [\"uv\", \"pip\"]\n\n[tool.hatch.envs.example.overrides]\nmatrix.tool.installer = { value = \"{matrix:tool}\" }\nmatrix.tool.scripts = [\n  { key = \"pip\", value = \"{env:HATCH_UV} pip {args}\", if = [\"uv\"] },\n]\n

      Another common use case is to expose UV to all test environments. In this case, you often wouldn't want to modify the scripts mapping directly but rather add an extra script:
        pyproject.toml hatch.toml 
      [tool.hatch.envs.hatch-test.extra-scripts]\npip = \"{env:HATCH_UV} pip {args}\"\n

       Setting up PATH 
      If you installed Hatch with pipx rather than system-wide, you might need to add $HOME/.local/bin to your PATH environment variable for your graphical session, not just your terminal. Check like this:

      For testing Hatchling plugins, you'll usually want to generate a project to execute builds as a real user would. For example, as a minimal pytest fixture:
       
      from pathlib import Path\n\nimport pytest\n\n\n@pytest.fixture\ndef new_project(tmp_path):\n    project_dir = tmp_path / 'my-app'\n    project_dir.mkdir()\n\n    project_file = project_dir / 'pyproject.toml'\n    project_file.write_text(\n        f\"\"\"\\\n[build-system]\nrequires = [\"hatchling\", \"hatch-plugin-name @ {Path.cwd().as_uri()}\"]\nbuild-backend = \"hatchling.build\"\n\n[project]\nname = \"my-app\"\nversion = \"0.1.0\"\n\"\"\",\n        encoding='utf-8',\n    )\n    ...\n
       
      The issue with this is that after the first test session, the project will be forever cached by pip based on the file path. Therefore, subsequent tests runs will never use updated code.
       
      To invalidate the cache, copy your code to a new path for every test session:
       
      import shutil\nfrom pathlib import Path\nfrom tempfile import TemporaryDirectory\n\nimport pytest\n\n\n@pytest.fixture(scope='session')\ndef plugin_dir():\n    with TemporaryDirectory() as d:\n        directory = Path(d, 'plugin')\n        shutil.copytree(\n            Path.cwd(), directory, ignore=shutil.ignore_patterns('.git')\n        )\n\n        yield directory.resolve()\n\n\n@pytest.fixture\ndef new_project(tmp_path, plugin_dir):\n    project_dir = tmp_path / 'my-app'\n    project_dir.mkdir()\n\n    project_file = project_dir / 'pyproject.toml'\n    project_file.write_text(\n        f\"\"\"\\\n[build-system]\nrequires = [\"hatchling\", \"hatch-plugin-name @ {plugin_dir.as_uri()}\"]\nbuild-backend = \"hatchling.build\"\n\n[project]\nname = \"my-app\"\nversion = \"0.1.0\"\n\"\"\",\n        encoding='utf-8',\n    )\n    ...\n

      This example chooses to ignore copying .git for performance reasons. You may want to ignore more patterns, or copy only specific paths like this plugin does.

      The run command supports executing Python scripts with inline metadata, such that a dedicated environment is automatically created with the required dependencies and with the correct version of Python.
       
      A script metadata block is a comment block that starts with # /// script and ends with # ///. Every line between those two lines must be a comment line that starts with # and contains a TOML document when the comment characters are removed.
       
      The top-level fields are:
       
         
      • dependencies: A list of strings that specifies the runtime dependencies of the script. Each entry must be a valid dependency specifier.

      Q: What is the risk of lock-in?
       
      A: Not much! Other than the plugin system, everything uses Python's established standards by default. Project metadata is based entirely on the standard, the build system is compatible with PEP 517/PEP 660, versioning uses the scheme specified by PEP 440, dependencies are defined with PEP 508 strings, and environments use virtualenv.
       
      Q: Must one use all features?
       
      A: No, all features are optional! You can use just the build system, publish wheels and source distributions that were built by other tools, only use the environment management, etc.
      "},{"location":"meta/faq/#libraries-vs-applications","title":"Libraries vs applications","text":"
      Q: Are workflows for both libraries and applications supported?
       
      A: Yes, mostly! Applications can utilize environment management just like libraries, and plugins can be used to build projects in arbitrary formats or publish artifacts to arbitrary destinations.
       
      The only caveat is that currently there is no support for re-creating an environment given a set of dependencies in a reproducible manner. Although a standard lock file format may be far off since PEP 665 was rejected, resolving capabilities are coming to pip. When that is stabilized, Hatch will add locking functionality and dedicated documentation for managing applications.

      Virtual environments necessarily require a parent installation of Python. The following rules determine how the parent is resolved.
       
      The Python choice is determined by the python option followed by the HATCH_PYTHON environment variable. If the choice is via the environment variable, then resolution stops and that path is used unconditionally.
       
      The resolvers will be based on the python-sources option and all resolved interpreters will ensure compatibility with the project's defined Python support.
       
      If a Python version has been chosen then each resolver will try to find an interpreter that satisfies that version.
       
      If no version has been chosen, then each resolver will try to find a version that matches the version of Python that Hatch is currently running on. If not found then each resolver will try to find the highest compatible version.
       
      Note
       
      Some external Python paths are considered unstable and are ignored during resolution. For example, if Hatch is installed via Homebrew then sys.executable will be ignored because the interpreter could change or be removed at any time.

      If you need to set linker environment variables like those starting with DYLD_ or LD_, any executable secured by System Integrity Protection that is invoked when running commands will not see those environment variable modifications as macOS strips those.
       
      Hatch interprets such commands as shell commands but deliberately ignores such paths to protected shells. This workaround suffices for the majority of use cases but there are 2 situations in which it may not:
       
         
      1. There are no unprotected sh, bash, zsh, nor fish executables found along PATH.
        2.  
      2. The desired executable is a project's script, and the location of environments contains spaces or is longer than 1241 characters. In this case pip and other installers will create such an entry point with a shebang pointing to /bin/sh (which is protected) to avoid shebang limitations. Rather than changing the location, you could invoke the script as e.g. python -m pytest (if the project supports that method of invocation by shipping a __main__.py).

      would be translated roughly to:

      If no environment options are selected, the test command will only run tests in the first defined environment that either already exists or is compatible. Additionally, the checking order will prioritize environments that define a version of Python that matches the interpreter that Hatch is running on.
       
      For example, if you overrode the default matrix as follows:
        pyproject.toml hatch.toml 
      [[tool.hatch.envs.hatch-test.matrix]]\npython = [\"3.12\", \"3.11\"]\n\n[[tool.hatch.envs.hatch-test.matrix]]\npython = [\"3.11\"]\nfeature = [\"foo\", \"bar\"]\n

      the expanded environments would normally be:
       
      hatch-test.py3.12\nhatch-test.py3.11\nhatch-test.py3.11-foo\nhatch-test.py3.11-bar\n
       
      If you install Hatch on Python 3.11, the checking order would be:
       
      hatch-test.py3.11\nhatch-test.py3.11-foo\nhatch-test.py3.11-bar\nhatch-test.py3.12\n
       
      Note
       
      If you installed Hatch with an official installer or are using one of the standalone binaries, the version of Python that Hatch runs on is out of your control. If you are relying on the single environment resolution behavior, consider explicitly selecting environments based on the Python version instead.
      "},{"location":"tutorials/testing/overview/#all-environments","title":"All environments","text":"
      You can run tests in all compatible environments by using the --all flag. For example, say you defined the matrix and overrides as follows:

      You can select subsets of environments by using the --include/-i and --exclude/-x options. These options may be used to include or exclude certain matrix variables, optionally followed by specific comma-separated values, and may be selected multiple times.
       
      For example, say you defined the matrix as follows:
        pyproject.toml hatch.toml 
      [[tool.hatch.envs.hatch-test.matrix]]\npython = [\"3.12\", \"3.11\"]\nfeature = [\"foo\", \"bar\", \"baz\"]\n

      If you wanted to run tests in all environments that have Python 3.12 and either the foo or bar feature, you could use the following command invocation:
       
      hatch test -i python=3.12 -i feature=foo,bar\n
       
      Alternatively, we could exclude the baz feature to achieve the same result:
       
      hatch test -i python=3.12 -x feature=baz\n
       
      Tip
       
      Since selecting the version of Python is a common use case, you can use the --python/-py option as a shorthand. For example, the previous commands could have been written as:
       
      hatch test -py 3.12 -i feature=foo,bar\nhatch test -py 3.12 -x feature=baz\n

      Managing environments
       
       
      Hatch environments are isolated workspaces that can be used for project tasks including running tests, building documentation and running code formatters and linters.
       
      The default environment
       
      When you start using Hatch, you can create the default environment. To do this use the env create command:
       
      hatch env create
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}      
       
        
         
       
       
       
       
       
       
        
       
       
       
       
       
        
       
       
       
       
          
      Managing environments
       
       
      Hatch environments are isolated workspaces that can be used for project tasks including running tests, building documentation and running code formatters and linters.
       
      The default environment
       
      When you start using Hatch, you can create the default environment. To do this use the env create command:
       
      hatch env create
 
       
      This will not only create will the default environment for you to work in but will also install your project in dev mode in this default environment.
       
       
      Tip
       
      You never need to manually create environments as spawning a shell or running commands within one will automatically trigger creation.
       
       
      Using the default environment
       
      Hatch will always use the default environment if an environment is not chosen explicitly when running a command.
       
      For instance, the following shows how to get version information for the Python in use.
       
      $ hatch run python -V
 Python 3.12.1
 
       
      Configure the default environment
       
      You can customize the tools that are installed into the default environment by adding a table called tool.hatch.envs.default to your pyproject.toml file. Below is an example of adding the dependencies pydantic and numpy to the default environment.

      Managing Python distributions
       
       
      The python command group provides a set of commands to manage Python distributions that may be used by other tools.
       
       
      Note
       
      When using environments, manual management is not necessary since by default Hatch will automatically download and manage Python distributions internally when a requested version cannot be found.
       
       
      Location
       
      There are two ways to control where Python distributions are installed. Both methods make it so that each installed distribution is placed in a subdirectory of the configured location named after the distribution.
       
         
      1. The globally configured default directory for Python installations.
        2.  
      2. The -d/--dir option of every python subcommand, which takes precedence over the default directory.
        3.  
       
      Installation
       
      To install a Python distribution, use the python install command. For example:
       
      hatch python install 3.12
+    body[data-md-color-scheme="slate"] .gslide-desc { color: var(--md-default-fg-color);}      
       
        
         
       
       
       
       
       
       
        
       
       
       
       
       
        
       
       
       
       
          
      Managing Python distributions
       
       
      The python command group provides a set of commands to manage Python distributions that may be used by other tools.
       
       
      Note
       
      When using environments, manual management is not necessary since by default Hatch will automatically download and manage Python distributions internally when a requested version cannot be found.
       
       
      Location
       
      There are two ways to control where Python distributions are installed. Both methods make it so that each installed distribution is placed in a subdirectory of the configured location named after the distribution.
       
         
      1. The globally configured default directory for Python installations.
        2.  
      2. The -d/--dir option of every python subcommand, which takes precedence over the default directory.
        3.  
       
      Installation
       
      To install a Python distribution, use the python install command. For example:
       
      hatch python install 3.12
 
       
      This will:
       
         
      1. Download the 3.12 Python distribution
        2.  
      2. Unpack it into a directory named 3.12 within the configured default directory for Python installations
        3.  
      3. Add the installation to the user PATH
        4.  
       
      Now its python executable can be used by you or other tools.
       
       
      Note
       
      For PATH changes to take effect in the current shell, you will need to restart it.
       
       
      Multiple
       
      You can install multiple Python distributions at once by providing multiple distribution names. For example:
       
      hatch python install 3.12 3.11 pypy3.10
 
       
      If you would like to install all available Python distributions that are compatible with your system, use all as the distribution name:
       
      hatch python install all
 
       
       
      Tip
       
      The commands for updating and removing also support this functionality.
       
       
      Private
       
      By default, installing Python distributions will add them to the user PATH. To disable this behavior, use the --private flag like so:
       
      hatch python install 3.12 --private

      Why Hatch?
       
       
      The high level value proposition of Hatch is that if one adopts all functionality then many other tools become unnecessary since there is support for everything one might require. Further, if one chooses to use only specific features then there are still benefits compared to alternatives.
       
      Build backend
       
      Hatchling, the build backend sister project, has many benefits compared to setuptools. Here we only compare setuptools as that is the one most people are familiar with.
       
         
      • Better defaults: The default behavior for setuptools is often not desirable for the average user.
           
        • For source distributions, setuptools has a custom enumeration of files that get included and excluded by default. Hatchling takes the defaults from your version control system such as Git's .gitignore file.
          •  
        • For wheels, setuptools attempts to find every directory that looks like a Python package. This is often undesirable as you might ship files to the end-user unintentionally such as test or tooling directories. Hatchling defaults to very specific inclusion based on the project name and errors if no heuristic is satisfied.
          •  
         
        •  
      • Ease of configurability: Hatchling was designed based on a history of significant challenges when configuring setuptools.
           
        • Hatchling uses the same glob pattern syntax as Git itself for every option which is what most users are familiar with. On the other hand, setuptools uses shell-style glob patterns for source distributions while wheels use a mix of shell-style globs and Python package syntax.
          •  
        • Configuring what gets included in source distributions requires a separate MANIFEST.in file. The custom syntax and directives must be learned and it is difficult knowing which options in the main files like setup.py influence the behavior and under what conditions. For Hatchling, everything gets configured in a single file under dedicated sections for specific targets like [tool.hatch.build.targets.wheel].
          •  
        • By default, non-Python files are excluded from wheels. Including such files requires usually verbose rules for every nested package directory. Hatchling makes no such distinction between file types and acts more like a general build system one might already be familiar with.
          •  
         
        •  
      • Editable installations: The default behavior of Hatchling allows for proper static analysis by external tools such as IDEs. With setuptools, you must provide additional configuration which means that by default, for example, you would not get autocompletion in Visual Studio Code. This is marked as a legacy feature and may in fact be removed in future versions of setuptools.
        •  
      • Reproducibility: Hatchling builds reproducible wheels and source distributions by default. setuptools does not support this for source distributions and there is no guarantee that wheels are reproducible.
        •  
      • Extensibility: Although it is possible to extend setuptools, the API is quite low level. Hatchling has the concept of plugins that are separated into discrete types and only expose what is necessary, leading to an easier developer experience.
        •  
       
      Why not?:
       
      If building extension modules is required then it is recommended that you continue using setuptools, or even other backends that specialize in interfacing with compilers.
       
      Environment management
       
      Here we compare to both tox and nox. At a high level, there are a few common advantages:
       
         
      • Python management: Hatch is able to automatically download Python distributions on the fly when specific versions that environments request cannot be found. The alternatives will raise an error, with the option to ignore unknown distributions.
        •  
      •  
        Philosophy: In the alternatives, environments are for the most part treated as executable units where a dependency set is associated with an action. If you are familiar with container ecosystems, this would be like defining a CMD at the end of a Dockerfile but without the ability to change the action at runtime. This involves significant wasted disk space usually because one often requires slight modifications to the actions and therefore will define entirely different environments inherited from a base config just to perform different logic. Additionally, this can be confusing to users not just configuration-wise but also for execution of the different environments.
         
        In Hatch, environments are treated as isolated areas where you can execute arbitrary commands at runtime. For example, you can define a single test environment with named scripts that runs unit vs non-unit tests, each command being potentially very long but named however you wish so you get to control the interface. Since environments are treated as places where work is performed, you can also spawn a shell into any which will execute a subprocess that automatically drops into your shell of choice. Your shell will be configured appropriately like python on PATH being updated and the prompt being changed to reflect the chosen environment.
         
        •  
      •  
        Configuration:
         
           
        • tox only supports INI configuration and if one desires putting that in the standard pyproject.toml file then it must be a multi-line string containing the INI config which would preclude syntax highlighting. Hatch allows for TOML-based config just like most other tools in the Python ecosystem.
          •  
        • nox config is defined in Python which often leads to increased verbosity and makes it challenging to onboard folks compared to a standardized format with known behaviors.
          •  
         
        •  
      • Extensibility:
           
        • tox allows for extending most aspects of its functionality however the API is so low-level and attached to internals that creating plugins may be challenging. For example, here is a tox plugin that was migrated to an equivalent Hatch environment collector plugin.
          •  
        • nox is configured with Python so for the local project you can do whatever you want, however there is no concept of third-party plugins per se. To achieve that, you must usually use a package that wraps nox and use that package's imports instead (example).
          •  
         
        •  
       
      Why not?:
       
      If you are using nox and you wish to migrate, and for some reason you notify sessions, then migration wouldn't be a straight translation but rather you might have to redesign that conditional step.
       
      Python management
       
      Here we compare Python management to that of pyenv.
       
         
      • Cross-platform: Hatch allows for the same experience no matter the system whereas pyenv does not support Windows so you must use an entirely different project that tries to emulate the functionality.
        •  
      • No build dependencies: Hatch guarantees that every available distribution is prebuilt whereas the alternative requires one to maintain a precise build environment which differs by platform and potentially Python version. Another benefit to this is extremely fast installations since the distributions are simply downloaded and unpacked.
        •  
      • Optimized by default: The CPython distributions are built with profile guided optimization and link-time optimization, resulting in a 10-30% performance improvement depending on the workload. These distributions have seen wide adoption throughout the industry and are even used by the build system Bazel.
        •  
      • Simplicity: Hatch treats Python installations as just another directory that one would add to PATH. It can do this for you or you can manage PATH yourself, even allowing for custom install locations. On the other hand, pyenv operates by adding shims which then act as wrappers around the actual underlying binaries. This has many unfortunate side effects:
           
        • It is incumbent upon the user to manage which specific Python comes first via the CLI, switch when necessary, and/or have a mental model of which versions are exposed globally and locally per-project. This can become confusing quite quickly. When working with Hatch, your global Python installations are only important insofar as they are on PATH somewhere since environments do not use them directly but rather create virtual environments from them, always using a version that is compatible with your project.
          •  
        • Configuration is required for each shell to properly set up pyenv on start, leading to inconsistencies when running processes that do not spawn a shell.
          •  
        • Debugging issues with Python search paths can be extremely difficult, especially for users of software. If you or users have ever ran into an issue where code was being executed that you did not anticipate, the issue is almost always pyenv influencing the python on PATH.
          •  
         
        •  
       
      Why not?:
       
      Currently, Hatch does not allow for the installation of specific patch release versions but rather only uses minor release granularity that tracks the latest patch release. If specific patch releases are important to you then it is best to use an alternative installation mechanism.

        • tox allows for extending most aspects of its functionality however the API is so low-level and attached to internals that creating plugins may be challenging. For example, here is a tox plugin that was migrated to an equivalent Hatch environment collector plugin.
          •  
        • nox is configured with Python so for the local project you can do whatever you want, however there is no concept of third-party plugins per se. To achieve that, you must usually use a package that wraps nox and use that package's imports instead (example).

      Why not?:
       
      If you are using nox and you wish to migrate, and for some reason you notify sessions, then migration wouldn't be a straight translation but rather you might have to redesign that conditional step.
       
      Python management
       
      Here we compare Python management to that of pyenv.
       
         
      • Cross-platform: Hatch allows for the same experience no matter the system whereas pyenv does not support Windows so you must use an entirely different project that tries to emulate the functionality.
        •  
      • No build dependencies: Hatch guarantees that every available distribution is prebuilt whereas the alternative requires one to maintain a precise build environment which differs by platform and potentially Python version. Another benefit to this is extremely fast installations since the distributions are simply downloaded and unpacked.
        •  
      • Optimized by default: The CPython distributions are built with profile guided optimization and link-time optimization, resulting in a 10-30% performance improvement depending on the workload. These distributions have seen wide adoption throughout the industry and are even used by the build system Bazel.
        •  
      • Simplicity: Hatch treats Python installations as just another directory that one would add to PATH. It can do this for you or you can manage PATH yourself, even allowing for custom install locations. On the other hand, pyenv operates by adding shims which then act as wrappers around the actual underlying binaries. This has many unfortunate side effects:
           
        • It is incumbent upon the user to manage which specific Python comes first via the CLI, switch when necessary, and/or have a mental model of which versions are exposed globally and locally per-project. This can become confusing quite quickly. When working with Hatch, your global Python installations are only important insofar as they are on PATH somewhere since environments do not use them directly but rather create virtual environments from them, always using a version that is compatible with your project.
          •  
        • Configuration is required for each shell to properly set up pyenv on start, leading to inconsistencies when running processes that do not spawn a shell.
          •  
        • Debugging issues with Python search paths can be extremely difficult, especially for users of software. If you or users have ever ran into an issue where code was being executed that you did not anticipate, the issue is almost always pyenv influencing the python on PATH.
          •  
         
        •  
       
      Why not?:
       
      Currently, Hatch does not allow for the installation of specific patch release versions but rather only uses minor release granularity that tracks the latest patch release. If specific patch releases are important to you then it is best to use an alternative installation mechanism.
