🤖 🚀 ✨ Emojify your conventional commits with Devmoji

#showdev #git #opensource #webdev

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 your commit message
git log: emojify and colorify the output of git log even for projects not using emojis

What does it look like?

generated Devmoji CHANGELOG.md

📦 Installation

Install with npm or yarn

globally



npm install -g devmoji
yarn global install 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.

💥 Usage

`devmoji --help`



$ 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
  -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

`devmoji` emojify

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

Format	Description
`shortcode`	outputs Github Markdown short codes like `:sparkles:` `:rocket:`
`unicode`	outputs the emoji unicode symbols like ✨ 🚀
`devmoji`	outputs the devmoji shortcodes like `:feat:` `:chore-release:`
`strip`	removes all emoji from the input

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

`devmoji --commit`

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

`devmoji --edit`

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

Configuration using Husky



// package.json
{
  "husky": {
    "hooks": {
      "prepare-commit-msg": "devmoji -e"
    }
  }
}

Configuration using Yorkie



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

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.

`devmoji --log`

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 >

`devmoji --list`

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

⚙️ Configuration

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

Example Config File



export const defaults = {

  // 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",

    },

  ],

}

I'd prefer my commits to not include emojis. They are distracting, especially in a terminal. The format below works fine without any emojis whatsoever.

<type>(<scope>): <short description>

<body>

<issue id, tags, etc.>

Rémi Lavedrine • Jan 16 '20

I love that.
Maybe it is not good to do that in a company as some people could not love this.
But on you personnal projects, if you do love that kind of visual stuff in your Git tree, that is a very good thing.

Folke Lemaitre • Jan 16 '20

Unless it's your own company 😉

Rémi Lavedrine • Jan 17 '20

Absolutely. 😄

I think this is a terrible idea, mostly because I struggle to read these little pictograms. Even when I do recognise that something's a firework rather than an explosion, I don't know whether that's a good thing or a bad thing.

I rely on the surrounding text to infer meaning by context. And at that point, why don't I just read the text; reading the text is orders of magnitude faster for me.

I'd hate to have to programatically search for something by whether it had a picture of an otter or a cat.

It's definitely inspired by Gitmoji, but Devmoji is meant to be used with the conventional commit message format. Emojis are automatically added with the prepare-commit-msg hook, based on the type and scope of the commit. Additionally, you can use emoji shortcodes like :security: :release: etc instead of 🔒 🚀, ... Easier to remember and fully customizable for your environment.
