Description

We have automation using commitzen (cz_conventional_commits) on Azure DevOps but all the pull requests generate a merge commit message that starts with the prefix "Merged PR XXXX: "

I would like avoid to editing all the merge commit message, so would be great to have an option to customize commitzen and ignore this prefix for cz bump allowing commits message like this:

Merged PR 1234: feat: add new language
Merged PR 8462: feat(lang): add Polish language
Merged PR 1346: fix(file.json): adjust boolean property
Merged PR 4732: refactor: rename files
Merged PR 7689: feat(api)!: send an email to the customer when a product is shipped

There is the customization parameter schema_pattern but I couldn't meet my needs. Does anyone know if it is possible to do what I want using this field? Otherwise, this new feature would be good.

Azure config

check if Azure Devops has a way to customize that prompt in order to remove the merge message. On github, if you squash a commit, it won't show the 'merge' message. Open a ticket and ask them to remove that.

Create your own set of custom rules

Publish your own set of rules: https://commitizen-tools.github.io/commitizen/customization/#2-customize-through-customizing-a-class
The default rule in commitizen is for conventional commits, which start with one of the keywords, not with Merged.

Try to customize the settings

https://commitizen-tools.github.io/commitizen/customization/#2-customize-through-customizing-a-class

You will have to modify a few I think, and the one you need the most is probably bump_pattern, it should look something like this:

[tool.commitizen.customize]
bump_pattern = "^Merged PR \d+: ((BREAKING[\-\ ]CHANGE|\w+)(\(.+\))?!?):"
commit_parser = "^Merged PR \d+: ((?P<change_type>feat|fix|refactor|perf|BREAKING CHANGE)(?:\((?P<scope>[^()\r\n]*)\)|\()?(?P<breaking>!)?|\w+!):\s(?P<message>.*)?"
changelog_pattern = "^Merged PR \d+: ((BREAKING[\-\ ]CHANGE|\w+)(\(.+\))?!?):"

Yes even when I do a regular merge, where I had multiple commits, after the merge git log only shows the merge commit like the above post. I wonder if this is related to how azure devops does git stuff like detached state.

mgeorgebrown89 Dec 13, 2023

AH! I think I figured it out. Azure Pipelines defaults to shallow fetch, which means its only getting the merge commit, which would explain why all the variations of regex I tried didn't seem to be reflected in the testing!

In the checkout step, set fetchDepth: 0 to override this. Documentation

If running git in a script, you can also set the --unshallow flag on git log.

Now, I think what I need to customize is less than what I have set in the file. I think changelog_pattern can be left as default, but I still need the tool to let the merge commit through.

If you feel like, I'd really appreciate a PR in the "Tutorials" sections with the explanation for Azure pipelines 🙏🏻

Hey, could you please share your devops pipeline configuration, along with detailed steps on how to integrate and use commitizen for version bumping?

Hi @zakpaw, here is my .cz.json that worked for me with Azure DevOps to ignore the Pull Request prefix Merged PR XXX:

{
  "commitizen": {
    "name": "cz_customize",
    "tag_format": "$version",
    "version_scheme": "semver",
    "version": "1.2.0",
    "update_changelog_on_bump": true,
    "bump_message": "Bump version $current_version -> $new_version [skip ci]",
    "customize": {
      "schema_pattern": "<type>(<scope>): <subject>\r\n<BLANK LINE>\r\n<body>\r\n<BLANK LINE>\r\n<footer>",
      "bump_pattern": "^(?:Merged PR \\d+: )?((BREAKING[\\-\\ ]CHANGE|\\w+)(\\(.+\\))?!?):",
      "commit_parser": "^(?:Merged PR \\d+: )?((?P<change_type>feat|fix|refactor|perf|BREAKING CHANGE)(?:\\((?P<scope>[^()\r\n]*)\\)|\\()?(?P<breaking>!)?|\\w+!):\\s(?P<message>.*)?",
      "changelog_pattern": "^(?:Merged PR \\d+: )?((BREAKING[\\-\\ ]CHANGE|\\w+)(\\(.+\\))?!?):"
    }
  }
}

Our pipeline is trigged every PR is completed to main branch and perform a task like this:

steps:
- script: |
    git config --global user.email "azuredevops@azuredevops.com"
    git config --global user.name "Azure DevOps"
    git fetch --prune --tags
    git checkout main
    git reset --hard origin/main

    cz bump --yes
    git push --tags origin main
  displayName: 'cz bump and push tag'
  condition: eq(variables['Build.SourceBranch'], 'refs/heads/main')
