changelogx

Yet another changelog generator from git commits, based on conventions and with an optional hook to enforce the rules

Install

npm i -g changelogx

add to your package.json a section like this:

{
  "changelogx": {
    // the text is passed to new RegExp with the flags gi.
    // if a commit matches any of the passed strings it will not be added to the final changelog
    "ignoreRegExp": ["DOC: add changelog", "generated changelog", "BLD: Release"],
    "issueIDRegExp" : "#(\\d+)", // regular expression to match issues found inside the changelog
    "commitURL": "https://github.com/royriojas/changelogx/commit/{0}", //the url for commits
    "authorURL": "https://github.com/{0}", //the url for the authors
    "issueIDURL": "https://github.com/royriojas/changelogx/issues/{0}", //the url for the issues
    "projectName": "changelogx" // the name of the project
  }
}

If no configuration file is provided or no changelogx configuration is found in the package.json, then The script will try to infer the settings assuming the module is hosted in github. Please verify the inferred configuration to verify is valid or provide your own configuration

  -c, --config String                  Path to your `changelogx` config. By Default will look for a `changelogx` section on your `package.json`

When no configuration is provided, some defaults based on your `package.json` file will be used. For Example:

"changelogx": {
  "ignoreRegExp": ["BLD: Release", "DOC: Generate Changelog", "Generated Changelog"],
  "issueIDRegExp" : "#(\\d+)",
  "commitURL": "https://github.com/$user$/changelogx/commit/{0}",
  "authorURL": "https://github.com/{0}",
  "issueIDURL": "https://github.com/$user$/changelogx/issues/{0}",
  "projectName": "changelogx"
}

Examples

• Generate an html changelog

  # this will create a changelog.html file
  changelogx -o changelog.html
  

• Generate a markdown changelog

  # this will create a markdown changelog
  changelog -f markdown -o changelog.md
  

• Generate the changelog to stdout

  # this will create a markdown changelog and print it to stdout
  changelog -f markdown
  

• Get a changelog between 2 tags

  # this will create a markdown changelog from v0.1.0 to v2.0.0 and print it to stdout
  changelog -f markdown --tagRange=v0.1.0..v2.0.0
  

• Only use certain type of tags

  # this will create a markdown changelog from v0.1.0 to v2.0.0 and print it to stdout ignoring other tags that don't start with `v`
  changelog -f markdown --tagRange=v0.1.0..v2.0.0 --tagPrefix=v
  

• Exclude certain commits

  # this will exclude all the commits that contain the passed text. the -i option is an array
  # so if passed several times it will populate the array
  changelog -i "DOC: Generate Changelog" -i "BLD: Release" -f markdown -o ./changelog.md
  

Bonus

Install commit-msg hook, in order to enforce the conventions to follow in order to generate this changelog.

# install the commit-msg hook setting the maximum subject line length to 160 characters
changelog install-hook -m 160

This will enforce the commits to follow the following structure:

  {TAG}:({FEATURE}) {SHORT_DESCRIPTION} {ISSUE_ID}

  {LONG_DESCRIPTION}

Where:

• TAG, Any of the following :

  • BLD: change related to build scripts
  • FIX: bugfixes, hotfixes.
  • BUG: alias for bugfixes, hotfixes.
  • DOC: documentation
  • FEAT: features new features
  • ENH: Performance enhancements, not captured in features
  • REF: maintenance commit (refactoring, etc.)
  • STY: style fix (whitespaces, typos)
  • TST: addition or modification of tests

• FEATURE. Useful to identify commits related to a given feature. Optional.

• SHORT_DESCRIPTION. A very short description for the commit

• ISSUE_ID (Optional). Provide one if you have it example, see: #40, #30

• LONG_DESCRIPTION (Optional). A longer description of the commit. You can use markdown to provide some nice formatting on the body as well. Also if you add here reference to issues they will be linked as well

Important: Messages starting with Revert or Merge will be considered valid, as they usually are created by git itself automatically.

Example:

$ git commit
FIX: (Build Issues) Fix Travis Build, This fix #20 and #25

Fix bug on build while installing

In one line

$ git commit -m "FIX: (Build Issues) Fix Travis Build. This fix #20 and #25"

If a commit does not follow this structure, the commit will be stopped
