git-changelog-command-line
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
jarcan be found in Maven Central and used likejava -jar git-changelog-command-line-*.jar ..... - The
npmpackage can be found in NPM. - The
Dockerimage can be found in Dockerhub and used likedocker run --mount src="$(pwd)",target=/usr/src/git-changelog-command-line,type=bind tomasbjerre/git-changelog-command-line:X --help.
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.

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: $nextVersion
There are default patterns, but you can specify the patterns with:
--major-version-pattern REGEXP--minor-version-pattern REGEXP--patch-version-pattern REGEXP
By default it will match anything as patch, like chore: whatever and not only fix: whatever. You can change that with:
highestVersion=$(npx git-changelog-command-line \
--print-highest-version)
highestVersionTag=$(npx git-changelog-command-line \
--print-highest-version-tag)
currentVersion=$(npx git-changelog-command-line \
--patch-version-pattern "^fix.*" \
--print-current-version)
if [ -z "$highestVersionTag" ]; then
echo "This is the first version in the repo, using 0.0.1 as version"
currentVersion=0.0.1
else if [ "$currentVersion" == "$highestVersion" ]; then
echo "No changes made that can be released"
else
echo "Changes detected and a new $currentVersion release can be made"
fi
A changelog can be rendered (using Helpers) like this:
npx git-changelog-command-line \
--to-ref HEAD \
--stdout \
--template-content "
# Changelog
## [](https://github.com/tomasbjerre/someproject/compare/) ()
### Features
- **** } ([](https://github.com/tomasbjerre/someproject/commit/))
### Bug Fixes
- **** } ([](https://github.com/tomasbjerre/someproject/commit/))
"
Or you can prepend to the current changelog. You may get $nextVersion from --print-next-version and $highestTag from --print-highest-version-tag. Somehting like this:
npx git-changelog-command-line \
--from-ref $highestTag \
--to-ref HEAD \
--prepend-to-file CHANGELOG.md \
--template-content "
## $nextVersion
## Features
**** } ([](https://github.com/tomasbjerre/someproject/commit/))
## Bug Fixes
**** } ([](https://github.com/tomasbjerre/someproject/commit/))
"
Example NPM and package.json
If you are using NPM, you may want to add this to your package.json:
{
"scripts": {
"build": "echo build it...",
"release": "npm run set-version; npm run build && npm publish && npm run changelog",
"set-version": "npm version $(npx git-changelog-command-line --print-next-version)",
"changelog": "npx git-changelog-command-line -of CHANGELOG.md && git commit -a -m 'chore: changelog' && git push --follow-tags"
}
}
And if you do npm run release it will:
- Set version in
package.json - Build the repo
- Publish it
- Update CHANGELOG.md
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 "
Starts with feat: ""
first 10 letters of hash is:
" \
--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);
}
});
