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

Using the env show command would then display:

The last step of the setup process is to define any dependencies that you'd like your project to begin with.

"},{"location":"intro/#configuration","title":"Configuration","text":"

All project-specific configuration recognized by Hatch can be defined in either the pyproject.toml file, or a file named hatch.toml where options are not contained within the tool.hatch table:

option = \"...\"\n\n[table1]\noption = \"...\"\n\n[table2]\noption = \"...\"\n

Top level keys in the latter file take precedence when defined in both.

Tip

If you want to make your file more compact, you can use dotted keys, turning the above example into:

pyproject.toml hatch.toml

"},{"location":"version/","title":"Versioning","text":""},{"location":"version/#configuration","title":"Configuration","text":"

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

The pattern must have a named group called version that represents the version.

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:

$ hatch version major,rc\nOld: 0.2.0\nNew: 1.0.0rc0\n

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.

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:

Why not?:

"},{"location":"why/#python-management","title":"Python management","text":"

Here we compare Python management to that of pyenv.

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.

Hatch v1.10.0 brings a test command, support for UV, and a Python script runner.

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:

Here is us testing Rich, with a bit of configuration:

"},{"location":"blog/2024/05/02/hatch-v1100/#uv","title":"UV","text":"

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.

See the how-to guide for more information about switching the installer.

"},{"location":"blog/2024/05/02/hatch-v1100/#python-script-runner","title":"Python script runner","text":"

The run command now supports executing Python scripts with inline metadata as standardized by PEP 723.

As an example, consider the following script:

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

If you run the script for the first time as follows:

hatch run script.py\n

Hatch will create a dedicated environment for that script using a version of Python greater than or equal to 3.11 with dependencies httpx and rich.

"},{"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:

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.

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.

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

"},{"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.

"},{"location":"blog/2023/12/11/hatch-v180/#build-improvements","title":"Build improvements","text":"

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.

"},{"location":"blog/2023/12/11/hatch-v180/#faster-environment-usage","title":"Faster environment usage","text":"

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.

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.

Run tests using the hatch-test environment matrix.

If no filtering options are selected, then tests will be run in the first compatible environment found in the matrix with priority given to those matching the current interpreter.

The -i/--include and -x/--exclude options may be used to include or exclude certain variables, optionally followed by specific comma-separated values, and may be selected multiple times. For example, if you have the following configuration:

pyproject.toml hatch.toml 
[[tool.hatch.envs.hatch-test.matrix]]\npython = [\"3.9\", \"3.10\"]\nversion = [\"42\", \"3.14\", \"9000\"]\n
[[envs.hatch-test.matrix]]\npython = [\"3.9\", \"3.10\"]\nversion = [\"42\", \"3.14\", \"9000\"]\n

then running:

hatch test -i py=3.10 -x version=9000\n

would run tests in the environments hatch-test.py3.10-42 and hatch-test.py3.10-3.14.

The -py/--python option is a shortcut for specifying the inclusion -i py=....

Note

The inclusion option is treated as an intersection while the exclusion option is treated as a union i.e. an environment must match all of the included variables to be selected while matching any of the excluded variables will prevent selection.
