Template - Semantic versioning from conventional commits
If you are using conventional commits:
<type>[optional scope]: <description>
[optional body]
[optional footer(s)]
A changelog can be rendered (using Helpers) like this:
# 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 add your own helpers and use them in the template. There are also built in Helpers.
apply plugin: "se.bjurr.gitchangelog.git-changelog-gradle-plugin"
import se.bjurr.gitchangelog.plugin.gradle.HelperParam;
import com.github.jknack.handlebars.Helper;
import com.github.jknack.handlebars.Options;
task gitChangelogTask(type: se.bjurr.gitchangelog.plugin.gradle.GitChangelogTask) {
file = new File("CHANGELOG.md");
handlebarsHelpers = [
new HelperParam("startsWith", new Helper<String>() {
public Object apply(String from, Options options) throws IOException {
def s = options.hash['s']
if (from.matches("^" + s + ".*")) {
return options.fn(this);
} else {
return options.inverse(this);
}
}
}),
new HelperParam("firstLetters", new Helper<String>() {
public Object apply(String from, Options options) throws IOException {
def number = new Integer(options.hash['number'])
return from.substring(0,number);
}
})
]
templateContent = """
{{#commits}}
{{#startsWith messageTitle s='feat'}}
Starts with feat: "{{messageTitle}}"
first 10 letters of hash is: {{firstLetters hash number='10'}}
{{/startsWith}}
{{/commits}}
""";
}
Get next release
It can also be used to get the next semantic version based on commits.
classpath 'se.bjurr.gitchangelog:git-changelog-lib:1.+'
...
buildscript {
repositories {
mavenCentral()
mavenLocal()
}
dependencies {
...
classpath 'se.bjurr.gitchangelog:git-changelog-lib:1.+'
}
}
def nextVersion = se.bjurr.gitchangelog.api.GitChangelogApi.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();
