Contributing to Atom

👍🎉 First off, thanks for taking the time to contribute! 🎉👍

The following is a set of guidelines for contributing to Atom and its packages, which are hosted in the Atom Organization on GitHub. These are just guidelines, not rules, use your best judgment and feel free to propose changes to this document in a pull request.

This project adheres to the Contributor Covenant 1.2. By participating, you are expected to uphold this code. Please report unacceptable behavior to atom@github.com.

Submitting Issues

• You can create an issue here, but before doing that please read the notes below on debugging and submitting issues, and include as many details as possible with your report.
• Check the debugging guide for tips on debugging. You might be able to find the cause of the problem and fix things yourself.
• Include the version of Atom you are using and the OS.
• Include screenshots and animated GIFs whenever possible; they are immensely helpful.
• Include the behavior you expected and other places you've seen that behavior such as Emacs, vi, Xcode, etc.
• Check the dev tools (alt-cmd-i) for errors to include. If the dev tools are open before the error is triggered, a full stack trace for the error will be logged. If you can reproduce the error, use this approach to get the full stack trace and include it in the issue.
• On Mac, check Console.app for stack traces to include if reporting a crash.
• Perform a cursory search to see if a similar issue has already been submitted.
• Please setup a profile picture to make yourself recognizable and so we can all get to know each other better.

Package Repositories

This is the repository for the core Atom editor only. Atom comes bundled with many packages and themes that are stored in other repos under the Atom organization such as tabs, find-and-replace, language-javascript, and atom-light-ui.

If your issue is related to a specific package, open an issue on that package's issue tracker. If you're unsure which package is causing your problem or if you're having an issue with Atom core, open an issue on this repository.

For more information on how to work with Atom's official packages, see Contributing to Atom Packages

Pull Requests

• Include screenshots and animated GIFs in your pull request whenever possible.
• Follow the CoffeeScript, JavaScript, and CSS styleguides.
• Include thoughtfully-worded, well-structured Jasmine specs in the ./spec folder. Run them using apm test. See the Specs Styleguide below.
• Document new code based on the Documentation Styleguide
• End files with a newline.
• Place requires in the following order:
  • Built in Node Modules (such as path)
  • Built in Atom and Atom Shell Modules (such as atom, shell)
  • Local Modules (using relative paths)
• Place class properties in the following order:
  • Class methods and properties (methods starting with a @)
  • Instance methods and properties
• Avoid platform-dependent code:
  • Use require('fs-plus').getHomeDirectory() to get the home directory.
  • Use path.join() to concatenate filenames.
  • Use os.tmpdir() rather than /tmp when you need to reference the temporary directory.
• Using a plain return when returning explicitly at the end of a function.
  • Not return null, return undefined, null, or undefined

Git Commit Messages

• Use the present tense ("Add feature" not "Added feature")
• Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
• Limit the first line to 72 characters or less
• Reference issues and pull requests liberally
• Consider starting the commit message with an applicable emoji:
  • 🎨 :art: when improving the format/structure of the code
  • 🐎 :racehorse: when improving performance
  • 🚱 :non-potable_water: when plugging memory leaks
  • 📝 :memo: when writing docs
  • 🐧 :penguin: when fixing something on Linux
  • 🍎 :apple: when fixing something on Mac OS
  • 🏁 :checkered_flag: when fixing something on Windows
  • 🐛 :bug: when fixing a bug
  • 🔥 :fire: when removing code or files
  • 💚 :green_heart: when fixing the CI build
  • ✅ :white_check_mark: when adding tests
  • 🔒 :lock: when dealing with security
  • ⬆️ :arrow_up: when upgrading dependencies
  • ⬇️ :arrow_down: when downgrading dependencies
  • 👕 :shirt: when removing linter warnings

CoffeeScript Styleguide

• Set parameter defaults without spaces around the equal sign
  • clear = (count=1) -> instead of clear = (count = 1) ->
• Use spaces around operators
  • count + 1 instead of count+1
• Use spaces after commas (unless separated by newlines)
• Use parentheses if it improves code clarity.
• Prefer alphabetic keywords to symbolic keywords:
  • a is b instead of a == b
• Avoid spaces inside the curly-braces of hash literals:
  • {a: 1, b: 2} instead of { a: 1, b: 2 }
• Include a single line of whitespace between methods.
• Capitalize initialisms and acronyms in names, except for the first word, which should be lower-case:
  • getURI instead of getUri
  • uriToOpen instead of URIToOpen
• Use slice() to copy an array
• Add an explicit return when your function ends with a for/while loop and you don't want it to return a collected array.
• Use this instead of a standalone @
  • return this instead of return @

Specs Styleguide

• Include thoughtfully-worded, well-structured Jasmine specs in the ./spec folder.
• treat describe as a noun or situation.
• treat it as a statement about state or how an operation changes state.

Example

describe 'a dog', ->
 it 'barks', ->
 # spec here
 describe 'when the dog is happy', ->
  it 'wags its tail', ->
  # spec here

Documentation Styleguide

• Use AtomDoc.
• Use Markdown.
• Reference methods and classes in markdown with the custom {} notation:
  • Reference classes with {ClassName}
  • Reference instance methods with {ClassName::methodName}
  • Reference class methods with {ClassName.methodName}

Example

# Public: Disable the package with the given name.
#
# * `name`    The {String} name of the package to disable.
# * `options` (optional) The {Object} with disable options (default: {}):
#   * `trackTime`     A {Boolean}, `true` to track the amount of time taken.
#   * `ignoreErrors`  A {Boolean}, `true` to catch and ignore errors thrown.
# * `callback` The {Function} to call after the package has been disabled.
#
# Returns `undefined`.
disablePackage: (name, options, callback) ->

Issue and Pull Request Labels

This section lists the labels we use to help us track and manage issues and pull requests. Most labels are used across all Atom repositories, but some are specific to atom/atom.

GitHub search makes it easy to use labels for finding groups of issues or pull requests you're interested in. For example, you might be interested in open issues across atom/atom and all Atom-owned packages which are labeled as bugs, but still need to be reliably reproduced or perhaps open pull requests in atom/atom which haven't been reviewed yet. To help you find issues and pull requests, each label is listed with search links for finding open items with that label in atom/atom only and also across all Atom repositories. We encourage you to read about other search filters which will help you write more focused queries.

The labels are loosely grouped by their purpose, but it's not required that every issue have a label from every group or that an issue can't have more than one label from the same group.

Please open an issue on atom/atom if you have suggestions for new labels, and if you notice some labels are missing on some repositories, then please open an issue on that repository.
