About Portage

Portage is a package management system based on ports collections. The
Package Manager Specification Project (PMS) standardises and documents
the behaviour of Portage so that ebuild repositories can be used by
other package managers.

Contributing

Contributions are always welcome! We’ve started using
black to format the code base. Please make
sure you run it against any PR’s prior to submitting (otherwise we’ll probably
reject it).

There are ways to
integrate
black into your text editor and/or IDE.

You can also set up a git hook to check your commits, in case you don’t want
editor integration. Something like this:

# .git/hooks/pre-commit (don't forget to chmod +x)

#!/bin/bash
black --check --diff .

One can also use pre-commit to run the configured pre-commit
hooks. Utilizing pre-commit has the advantage of running the linter
over only the changed files, resulting in a much faster pre-commit
hook. To use, install pre-commit and then install the hook to your
.git:

emerge dev-vcs/pre-commit
pre-commit install

To ignore commit 1bb64ff452 (and other reformatting commits) which is a
massive commit that simply formatted the code base using black - you can do
the following:

git config blame.ignoreRevsFile .git-blame-ignore-revs

Dependencies

Python and Bash should be the only hard dependencies. Python 3.9 is the
minimum supported version.

Native Extensions

Portage includes some optional native extensions which can be built
in the source tree by running the following command:

python setup.py build_ext --inplace --portage-ext-modules

The following setup.cfg settings can be used to enable building of
native extensions for all invocations of the build_ext command (the
build_ext command is invoked automatically by other build commands):

   [build_ext]
   portage_ext_modules=true

Currently, the native extensions only include libc bindings which are
used to validate LC_CTYPE and LC_COLLATE behavior for EAPI 6. If the
native extensions have not been built, then portage will use ctypes
instead.
