mess

Simple, file-based dependency management with git and local overrides.

Installation

Download the latest version of the mess script into your project repo:

wget https://raw.githubusercontent.com/commonspub/mess/main/mess.exs

Add this line to top the top of your mix.exs:

Code.eval_file("mess.exs")

Where you would normally return a list of dependencies, just call Mess.deps/1, passing any override dependencies:

defp deps do
  Mess.deps []
end

Configuration

By default, mess will consult three files:

• deps.path
• deps.git
• deps.hex

These files use a simple key="value" format. Keys are package names and values are hex version specs, paths or git urls. It's pretty forgiving about whitespace, but you do need to provide the quotes. You can add comments with #.

deps.git is treated slightly specially, in that the values may suffix # and the name of a branch.

Otherwise these are all merged together, with dependencies in earlier files taking precedence over dependencies in later files. The provided overrides take precedence over all file data.

There isn't currently a way to provide custom options (such as only:) - use overrides.
