simple-commit-message

Simple commit message wizard and validator; works with commitizen and pre-git

NPM

Build status dependencies devdependencies semantic-release manpm standard-style

Purpose

This module can:

  • parse simple commit message of the type type(scope): message
  • validate a given message if it fits the above simple format
  • guide the user with questions in order to form well formatted message

Valid commit messages

Simplest

major: breaking change in API
minor: this is a new feature
fix: an example fix message

Synonyms

For convenience you can use synonyms:

  • "break: ..." is synonym to "major: ..."
  • "feat: ..." is synonym to "minor: ..."
  • "patch: ..." is synonym to "fix: ..."

Scopes

You can optionally put a scope for the commit. For example if you added a new feature to the log feature of the module

feat(log): added colors!

Similarly, you can add scope to each type

major(scope): breaking change in API
minor(something): this is a new feature
fix(login): an example fix message

Skip release

If you just want to commit code, but not publish a new version from CI, you have several choices.

chore(tests): writing more tests
WIP: work in progress, not ready yet

note if you have local commit message validation as a Git hook, for example using pre-git skip the message check using git commit -n option.

Comments

The commit message can have lines that start with # character. These lines will be ignored.

Install and use

npm install --save simple-commit-message

Then use the following methods

var simple = require('simple-commit-message')
simple.name // "simple"
// returns an object with parsed info
const result = simple.parse(message)
/*
  {
    firstLine, // first message line
    type,      // "major", "feat", "fix", "chore" or undefined
    scope,     // inside of round braces
    subject    // message after :
*/
// returns true / false, prints errors to given log function or console.error
simple.validate(message, log)
// message wizard built on top of inquirer
simple.prompter(inquirer, cb)
// returns true if the commit message is public ("feat", etc)
simple.isPublic(
  simple.parse("feat(foo): add foo feature").type
) // true

See inquirer for details.

As plugin for semantic-release

This module can function as analyzeCommits plugin for semantic-release. Just add to the package.json (during install this will be done automatically)

{
  "release": {
    "analyzeCommits": "simple-commit-message"
  }
}

Versions

  • 1 ... 3.x compatible with semantic-release v8
  • 4 compatible with semantic-release v11

Wizard

This module comes with included "bin" script that runs the wizard and asks you the questions. To use, add a script to your package, for example name it "commit"

{
    "scripts": {
        "commit": "simple-commit-message"
    }
}

Then instead of git commit use the command npm run commit and answer questions.

Debugging

To see the commit processing logic locally, run

GH_TOKEN=aaa NPM_TOKEN=fff $(npm bin)/semantic-release pre || true && git checkout .npmrc

This will trigger local commit analysis without publishing.

To see debug log messages run this plugin with DEBUG=simple environment variable.
