Turns git log output into a grouped markdown changelog using conventional commit prefixes such as feat, fix and docs. Use when the user prepares a release, asks for release notes, or wants a summary of what changed between two tags.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Changelog generator
Groups commit subjects by type so release notes can be written in minutes.
## When to use
- The user is cutting a release and needs notes.
- The user asks what changed since the last tag.
- A pull request needs a summary of its commits.
## How to run
Pipe `git log` with the `%h|%s` format into the script:
```bash
git log v1.0.0..HEAD --pretty=format:"%h|%s" | python scripts/make_changelog.py --title "v1.1.0"
```
Without a title, the heading is `Changelog`.
## Output
Markdown on standard output. Sections appear in a fixed order: Breaking changes, Features, Fixes,
Performance, Documentation, Refactoring, Tests, Build and CI, Other. Empty sections are left out.
A `!` after the type (`feat!:`) or a `BREAKING CHANGE` marker puts the commit under Breaking changes.
Each line shows the scope in bold, the subject and the short hash.
## After running
Read the draft once, merge duplicate lines, and rewrite subjects that only make sense to the author.
Add a short summary paragraph on top for releases with user visible changes.
## Errors
Empty input prints a heading and the line `No commits found.`. Lines without a `|` separator are ignored.
The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
