Git Changelog Command Line

Maven Central NPM

This is a command line tool for generating a changelog, or releasenotes, from a GIT repository. It uses the Git Changelog Lib.

This is a Java application (runnable jar) packaged into an NPM package for convenience. The runnable jar can be found in Maven Central and used like java -jar git-changelog-command-line-*.jar ..... The npm package can be found in NPM.

Example - Simple

A changelog can be created like this.

npx git-changelog-command-line -std

Or, you can specify a template:

npx git-changelog-command-line -std -tec "
# Changelog

Changelog.

{{#tags}}
## {{name}}
 {{#issues}}
  {{#hasIssue}}
   {{#hasLink}}
### {{name}} [{{issue}}]({{link}}) {{title}} {{#hasIssueType}} *{{issueType}}* {{/hasIssueType}} {{#hasLabels}} {{#labels}} *{{.}}* {{/labels}} {{/hasLabels}}
   {{/hasLink}}
   {{^hasLink}}
### {{name}} {{issue}} {{title}} {{#hasIssueType}} *{{issueType}}* {{/hasIssueType}} {{#hasLabels}} {{#labels}} *{{.}}* {{/labels}} {{/hasLabels}}
   {{/hasLink}}
  {{/hasIssue}}
  {{^hasIssue}}
### {{name}}
  {{/hasIssue}}

  {{#commits}}
**{{{messageTitle}}}**

{{#messageBodyItems}}
 * {{.}}
{{/messageBodyItems}}

[{{hash}}](https://github.com/{{ownerName}}/{{repoName}}/commit/{{hash}}) {{authorName}} *{{commitTime}}*

  {{/commits}}

 {{/issues}}
{{/tags}}
"

Example - Semantic versioning from conventional commits

If you are using conventional commits:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

The highest version can be determined with:


highestTag=$(npx git-changelog-command-line \
 --print-highest-version-tag)

echo Last release detected as $highestTag

You can also get the tag with --print-highest-version-tag. Highest version may be 1.2.3 and highest tag may be v1.2.3.

Next version to release can be determined with:

nextVersion=$(npx git-changelog-command-line \
 --print-next-version)

echo Next release based on commits is: $nextVersion

There are default patterns, but you can specify the patterns with:

  • --major-version-pattern REGEXP
  • --minor-version-pattern REGEXP
  • --patch-version-pattern REGEXP

A changelog can be rendered (using Helpers) like this:

npx git-changelog-command-line \
 --to-ref HEAD \
 --stdout \
 --template-content "
# Changelog

{{#tags}}
{{#ifReleaseTag .}}
## [{{name}}](https://gitlab.com/html-validate/html-validate/compare/{{name}}) ({{tagDate .}})

  {{#ifContainsType commits type='feat'}}
### Features

    {{#commits}}
      {{#ifCommitType . type='feat'}}
 - {{#eachCommitScope .}} **{{.}}** {{/eachCommitScope}} {{{commitDescription .}}} ([{{hash}}](https://gitlab.com/html-validate/html-validate/commit/{{hashFull}}))
      {{/ifCommitType}}
    {{/commits}}
  {{/ifContainsType}}

  {{#ifContainsType commits type='fix'}}
### Bug Fixes

    {{#commits}}
      {{#ifCommitType . type='fix'}}
 - {{#eachCommitScope .}} **{{.}}** {{/eachCommitScope}} {{{commitDescription .}}} ([{{hash}}](https://gitlab.com/html-validate/html-validate/commit/{{hashFull}}))
      {{/ifCommitType}}
    {{/commits}}
  {{/ifContainsType}}

{{/ifReleaseTag}}
{{/tags}}
"

Example - custom helpers

You can supply your own helpers and use them in the template.

npx git-changelog-command-line \
 --to-ref HEAD \
 --stdout \
 --template-content "
{{#commits}}
  {{#startsWith messageTitle s='feat'}}
    Starts with feat: "{{messageTitle}}"
    first 10 letters of hash is: {{firstLetters hash number='10'}}
  {{/startsWith}}
{{/commits}}
" \
--register-handlebars-helper "
Handlebars.registerHelper('firstLetters', function(input, options) {
  const number = parseInt(options.hash['number'] || "0")
  return input.substring(0,number);
});

Handlebars.registerHelper('startsWith', function(from, options) {
  const s = options.hash['s']
  if (new RegExp('^' + s + '.*').test(from)) {
    return options.fn(this);
  } else {
    return options.inverse(this);
  }
});
"

Usage - template base dir

You can use partials in your templates.

/dir/changelog.hbs

{{#commits}}
{{> commit}}
{{/commits}}

/dir/base/commit.partial

## {{authorName}} - {{commitTime}}
[{{hashFull}}](https://server/{{hash}})
{{{message}}}

This is configured like:

npx git-changelog-command-line -std \
 --template-base-dir /dir/base \
 --template /dir/changelog.hbs

If partials have a different ending, you can specify that with --template-partial-suffix.
