Available commands

get

Check and display the latest version of a changelog file, which is by default the CHANGELOG.md file in the current directory.

python3 -m changelog_tools get

<CHANGELOG_PATH> (optional)

Specifies a changelog path. If given path is a directory, the tool defaults a CHANGELOG.md file in that directory.

python3 -m changelog_tools get data/CHANGELOG.md

summarize

To get a list of changes between two versions, run the script:

python3 -m changelog_tools summarize --old <old_version> --new <new_version> <changelog_path>

--old (optional) Specifies a version from which to start looking for changes. This version corresponds to the lowest/oldest of the file. If not provided, the tool defaults to the initial version. If provided version does not exist in the file, it'll raise an error.

--new (optional) Specifies a version to end looking for changes. This version corresponds to the highest/latest version of the file. If not provided, the tool defaults to the latest version. If provided version does not exist in the file, it'll raise an error.

--include_unreleased (optional) Set by default to False. It is used to include unreleased items to the output, if needed.

<CHANGELOG_PATH> (optional)

Specifies a changelog path. If given path is a directory, the tool defaults a CHANGELOG.md file in that directory.
