Git Changelog Command Line
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 -tec "
# Changelog
Changelog.
{{#tags}}
#
{{#issues}}
{{#hasIssue}}
{{#hasLink}}
#
{{/hasLink}}
{{^hasLink}}
#
{{/hasLink}}
{{/hasIssue}}
{{^hasIssue}}
#
{{/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 $highestTag
Next version to release can be determined with:
nextVersion=$(npx git-changelog-command-line \
--major-version-pattern "^[Bb]reaking.*" \
--minor-version-pattern "^[Ff]eat.*" \
--print-next-version)
echo Next release based on commits is: $nextVersion
A changelog can be rendered (using Helpers) like this:
npx git-changelog-command-line \
--to-ref HEAD \
--stdout \
--template-content "
# Changelog
{{#tags}}
{{#ifReleaseTag .}}
#
{{#ifContainsType commits type='feat'}}
#
{{#commits}}
{{#ifCommitType . type='feat'}}
- {{#eachCommitScope .}} **{{.}}** {{/eachCommitScope}} {{{commitDescription .}}} ([{{hash}}](https://gitlab.com/html-validate/html-validate/commit/{{hashFull}}))
{{/ifCommitType}}
{{/commits}}
{{/ifContainsType}}
{{#ifContainsType commits type='fix'}}
#
{{#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);
}
});
