Heuristic update detection

This package can do automated lookups based on commonly used hosts. Currently:

• GitHub archives
• GitHub commit hashes
• GitHub releases
• JetBrains products
• PyPI

This works as long as the version system is usable with Portage's version comparison function. For anything else, see Package configuration.

Package configuration

For packages that will not work with currently heuristic checking, a configuration file named livecheck.json can be placed in the directory alongside the ebuild.

Configuration keys

• type - none, regex, or checksum
• branch - The GitHub branch name to use for commits
• no_auto_update - boolean - Do not allow auto-updating of this package
• regex - The regular expression to use
• semver - When set to false, do not allow detection of semantic versioning
• transformation_function - string - Function to use to transform the version string. Currently only dotize is supported. Others are for internal use.
• url - URL of the document to run regular expressions against
• use_vercmp - boolean - if vercmp from Portage should be used. Default: true.

Development use

Set up PYTHONPATH

As root, set the environment variable PYTHONPATH to include where the livecheck module is located. Use python -m livecheck instead of livecheck to execute commands.

With a virtualenv

Run poetry install --all-extras --with=dev,docs,tests to set up a virtualenv.

Fully copy /etc/portage to the root of your virtualenv. Then you must fix make.profile. Also consider making changes in repos.conf if necessary.

Example:

poetry shell
cd "${VIRTUAL_ENV}/etc"
cp -R /etc/portage .
cd portage
ln -sf "$(readlink -f /etc/portage/make.profile)" make.profile
