This is a library that can:
- Generate a changelog, or releasenotes, from a GIT repository.
- Determine next version, based on format of commits since last release.
It is fully configurable with a Mustache (Handlebars) template filled with a context of placeholders and helpers.
The changelog can:
- Be stored to file, like
CHANGELOG.md. There are some templates used for testing available here. - Or, just rendered to a
String.
It can integrate with Jira, Redmine, GitLab and/or GitHub to retrieve the title of issues.
This software can be used:
- With a Gradle plugin.
- With a Maven plugin.
- With a Jenkins plugin.
- From command line.
- From Docker.
- As a library Maven Central.
There are examples of different templates in the code that are used for testing.
Here is an example template.
If you are using conventional commits:
<type>[optional scope]: <description>
[optional body]
[optional footer(s)]You can use built in helpers to produce a nice changelog. You can add your own helpers (using Javascript or Java) as described here.
You can use partials in your templates.
changelog.hbs
commit.partial
This is configured like:
gitChangelogApi
.withTemplateBaseDir("...")
.withTemplateSuffix(".partial"); //Optional, defaults to ".partial"Some helpers are implemented in this library. And users can also add more helpers as described in Handlebars. If you add your own helpers, using Javascript, you will need to add a scriptengine like Nashorn to your classpath.
Conditional, renders a block if given Tag matches release-tag.

Conditional, renders a block if given List<Issue> contains given type.
Conditional, renders a block if given List<Issue> contains issues that don't match the given type.
Conditional, renders a block if given List<Issue> contains given label.
Conditional, renders a block if given List<Issue> contains labels that don't match the given label.
Conditional, renders a block if given label matches the given value.
Conditional, renders a block if given List<Commits> contains given type.
Conditional, renders a block if given List<Commits> contains commits that don't match the given type.
Conditional, renders a block if given List<Commits> contains breaking changes.
Renders date of Commit on format YYYY-MM-DD.
Renders description of Commit.
Renders reverted commit refered to by Commit.
Conditional, renders a block if given Issue is of type.
Conditional, renders a block if given Issue is of type.
Conditional, renders a block if given Commit is of type.
Conditional, renders a block if given Commit is of type.
Conditional, renders a block if given Commit is breaking.
Conditional, renders a block if given Commit has scope.
Conditional, renders a block if given Commit has footers.
Conditional, renders a block if given Commit has paragraphs.
Renders block for each scope in Commit.
Renders block for each refs in Commit.
Renders block for each fixes in Commit.
Renders block for each paragraph in Commit.
Renders block for each footer in Commit.
Optional tokenMatching regex parameter filters footer tokens.
Conditional, renders a block if given Footer has value.
Conditional, renders a block if a equals b.
Conditional, renders a block if a matches regexp b.
Works just like Java substring.
The template is supplied with this context of prepopulated mustache/handlebars variables:

It has a builder for creating the changelog.
gitChangelogApiBuilder()
.withFromCommit(ZERO_COMMIT)
.withToRef("refs/heads/master")
.withTemplatePath("changelog.mustache")
.render();It can be used to calculate next version number, based on commits:
def nextVersion = gitChangelogApiBuilder()
.withSemanticMajorVersionPattern("^[Bb]reaking")
.withSemanticMinorVersionPattern("[Ff]eature")
.getNextSemanticVersion();
println "Next version:" + nextVersion.toString();
println " Major:" + nextVersion.getMajor();
println " Minor:" + nextVersion.getMinor();
println " Patch:" + nextVersion.getPatch();Settings can be supplied with the build or from a JSON config (documented here).
