Using Conventional Commits ⭐ as a standard for your commit messages, makes Semantic Versioning 🔖 as easy as can be, with tools like Conventional Changelog 📄, Standard Version 🔖 and Semantic Release 📦🚀

Devmoji is a command line tool that adds color 🌈 to conventional commits, using emojis inspired by Gitmoji 😜

Some of the things Devmoji can do:

• emojify: convert input between diferent emoji formats unicode, shortcode and devmoji. devmoji are easy to remember aliases like: :test:, :refactor:, :docs:, :security instead of hard to remember emoji codes
• git commit: install a prepare-commit-msg commit hook to ✨ automagically emojify and lints your commit message
• git log: emojify and colorify the output of git log even for projects not using emojis

What does it look like?

• see the commit messages of the Devmoji github repository
• generated Devmoji CHANGELOG.md

Install with npm or yarn

globally

npm install -g devmoji
yarn global add devmoji

locally inside your project. use with npx devmoji

npm install --dev devmoji
yarn add --dev devmoji

See --edit for information on how to setup a git commit hook.

$ devmoji --help
Usage: devmoji [options]

Options:
  -c|--config <file>    location of the devmoji.config.js file
  -l|--list             list all known devmojis
  -t|--text <text>      text to format. reads from stdin when omitted
  --lint                lint the conventional commit. disabled for --log
  -f|--format <format>  format should be one of: unicode, shortcode, devmoji (default: "unicode")
  --commit              automatically add a devmoji to the conventional commit header (default: true)
  --no-commit           do not process conventional commit headers
  -e|--edit             read last commit message from .git/COMMIT_EDITMSG in the git root
  --log                 format conventional commits in text similar to git log
  --color               use colors for formatting. Colors are enabled by default, unless output is piped to another command (default: true)
  --no-color            don't use colors
  --version             output the version number
  -h, --help            output usage information

Emojify text using --text or piping it to stdin. Input can be a combination using any valid format. Output formats:

The default format is unicode, since this can be used pretty much everywhere and has the shortest text length (relevant for commit messages)

$ echo "This is a :test: of the first :release: :boom: ✨" | devmoji --format shortcode
This is a :rotating_light: of the first :rocket: :boom: :sparkles:

$ echo "This is a :test: of the first :release: :boom: :sparkles:" | devmoji --format unicode
This is a 🚨 of the first 🚀 💥 ✨

$ echo "🚀 :boom: :sparkles:" | devmoji --format devmoji
:chore-release: :breaking: :feat:

$ echo "test 🚀 :boom: :sparkles: :security:" | devmoji --format strip
test

Automagically ✨ emojifies a conventional commit message of the format type(scope): something useful, using the following pseudo code:

if (exists(":type-scope:")) return emoji(":type-scope:")

if (exists(":type:") && exists(":scope:"))
  return emoji(":type:") + emoji(":scope:")

if (exists(":type:")) return emoji(":type:")

example ouput:

$ echo "feat: added a new feature :smile:" | devmoji --commit
feat: ✨ added a new feature 😄

$ echo "chore(release): 1.1.1" | devmoji --commit
chore(release): 🚀 1.1.1

$ echo "fix(security): upgraded lodash" | devmoji --commit
fix(security): 🐛 🔒 upgraded lodash

Lints your commit message to see if they are valid conventional commits

Formats and saves your current commit message .git/COMMIT_EDITMSG. This is only really useful as a prepare-commit-msg or commit-msg hook.

When to use what hook?

• prepare-commit-msg: use this if you do not use Devmnojis --lint option and want to use it with something like commitlint instead.
• commit-msg: use this hook if you also want to use Devmoji for linting

Configuration using Husky

# make sure husky hooks are installed
$ npx husky install

# add a hook for devmoji
$ npx husky add .husky/prepare-commit-msg "npx devmoji -e --lint"

Configuration using Yorkie

// package.json
{
  "gitHooks": {
    "prepare-commit-msg": "devmoji -e --lint"
  }
}

If you installed Devmoji locally in your project as a dev dependency, then use something like npx --no-install devmoji -e instead of the commands above.

Alternatively, if you don't want to use Husky or Yorkie, you can manually create the git hooks.

Works similar to --commit, but formats type(scope): something useful anywhere in the input instead of the beginning of the first line.

This is useful to format the output of git log. Any git log option works, but my favorite alias is:

$ git log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --decorate --date=short

I'll use my alias git l, instead of the above, for clarity. The devmoji --format strip is only for demonstration purposes, since all devmoji commits already have emoji

using devmoji --log >

To get a list of all available Devmoji, run with --list. (see also Default Devmoji)

devmoji uses the config file as specified with the --config option, or looks for devmoji.config.js in the following paths:

• current directory
• parent directory that contains a package.json file
• parent directory that is a git repository
• home directory

module.exports = {
  // extra types used in commit messages
  types: ["lint"],
  // custom devmoji
  devmoji: [
    // use :boom: instead of :sparkles: for the type 'feat'
    { code: "feat", emoji: "boom" },
    // add a custom devmoji
    {
      code: "fail",
      emoji: "poop",
      description: "something bad happened",
    },
    // add a new devmoji based on an existing gitmoji. description will be taken from the gitmoji
    {
      code: "css",
      gitmoji: "art",
    },
    // the emoji from the gitmoji can be overriden as well
    {
      code: "config",
      gitmoji: "wrench",
      emoji: "gear",
    },
  ],
}
