GitHub Workflow Status Crates.io

A Conventional commit cli.

convco gives tools to work with Conventional Commits.

The tool is still in early development. It provides already the following commands:

  • convco changelog: Create a changelog file.
  • convco check: Checks if a range of commits is following the convention.
  • convco commit: Helps to make conventional commits.
  • convco version: Finds out the current or next version.


cargo install convco

Docker usage

# build the convco image
docker build -t convco .
# run it on any codebase
docker run -v "$PWD:/tmp" --workdir /tmp --rm convco

Use it in .gitlab-ci.yml

If you've created an image and pushed it into your private registry

  stage: test
    name: convco/convco:latest
    - check



A changelog can be generated using the conventional commits. It is inspired by conventional changelog. Configuration follows the conventional-changelog-config-spec

convco changelog > CHANGELOG.md


Check a range of revisions for compliance.

It returns a non zero exit code if some commits are not conventional. This is useful in a pre-push hook.

convco check $remote_sha..$local_sha


Helps to make conventional commits. A scope, description, body, breaking change and issues will be prompted.

# commit a new feature and then run git commit with the interactive patch switch
convco commit --feat -- --patch


When no options are given it will return the current version. When --bump is provided, the next version will be printed out. Conventional commits are used to calculate the next major, minor or patch. If needed one can provide --major, --minor or --patch to overrule the convention.

convco version --bump

It is useful to use it with release tools, such as cargo-release:

cargo release $(convco version --bump)


  • automatic notes for breaking changes
