cz_legacy

Custom Commitizen parser for user-specified legacy change types. The parser utilizes the cz_conventional_commits pattern and extends with the tag mapping specified in the configuration file

While old change types will appear in the Changelog, the user will be prevented from using them in new commits. This is the reverse of the revert/chore logic from commitizen that allows use of those commit types, but won't display them in the changelog

Alternatives

This customization only works when old commits use the <change_type>: <message> format that can be parsed by commitizen. If that doesn't fit your use case, you may want to try out incremental which (I think) prepends to an existing CHANGELOG

Usage

Install

Install the package from PyPi: pip install cz_legacy or from git: pip install git+https://github.com/KyleKing/cz_legacy.git@main

Configuration

At minimum, you must have the name = "cz_legacy" and [tool.commitizen.cz_legacy_map] in your configuration file. The below example is for TOML, you can also utilize a YAML or JSON file.

Below is an example of the three change legacy types Chg, Fix, and New, but the user can choose any tag names and associated mapping for the Changelog

[tool.commitizen]
name = "cz_legacy"
# Other tool.commitizen configuration options

[tool.commitizen.cz_legacy_map]
Chg = "Change (old)"
Fix = "Fix (old)"
New = "New (old)"

Pre-Commit

To use in pre-commit, add this to your pre-commit-config.yml

repos:
  - repo: https://github.com/commitizen-tools/commitizen
    rev: v2.11.1

Background

I couldn't find a good way of adding a few legacy change types from an old commit style to commitizen so I built a package to extend the ConventionalCommitsCz to provide custom logic. For reference, these are the default settings
