EditorConfig helps developers maintain consistent coding styles between different editors.

"I will take a peanut butter sandwich on white bread" -- Ralph S. Mouse


$ apm install editorconfig

Or, Settings → Install → Search for editorconfig

Getting started

See the EditorConfig documentation for a detailed description of the .editorconfig file format.

  1. Open a project containing an .editorconfig file.
  2. Whenever you open a file in the project (or change any .editorconfig file from within Atom), EditorConfig evaluates the EditorConfig settings for the current file.
  3. EditorConfig then applies these settings to your current editor pane. Any change you make from now on will follow the EditorConfig settings. EditorConfig does not automatically fix older files it considers as malformed.
  4. You can always check your EditorConfig settings against the current file using the EditorConfig: Show State command. You can try to fix malformed files using the command EditorConfig: Fix File.

💡 If EditorConfig detects any issues which may prevent it from working properly a 🐭 will appear in the status bar; click on it to open the state notification.

⚠️ EditorConfig will not automatically fix malformed files (e.g. change all soft tabs to hard tabs) -- you need to use the EditorConfig: Fix File command on each malformed file. Keep in mind that malformed files (especially mixed tab characters) may lead to unexpected behaviour.

Supported properties

💡 Any malformed or missing property falls back to unset which leaves the control to Atom.

⚠️ Atom does not support CR line-endings. When end_of_line is set to cr, EditorConfig will respect the setting when saving files, but their contents will appear to be squashed onto a single line.

EditorConfig commands

  • EditorConfig: Fix File: Fixes indent_style and end_of_line issues for the current editor.
  • EditorConfig: Fix File Quietly: Same as Fix File, except no feedback is displayed after fixing.
  • EditorConfig: Show State: Shows the current state of EditorConfig for your current editor.
  • EditorConfig: Generate Config: Generates an initial .editorconfig for your project.


  • Applies the settings from your .editorconfig file
  • Ability to fix indent_style and end_of_line issues
  • Syntax highlights .editorconfig files (now with specification-like case insensitivity)
  • Lint .editorconfig file
  • Ability to generate an .editorconfig file based on the current settings
  • Displays a nifty 🐭 in the statusBar whose color shows you if EditorConfig faces any problems
  • Clicking on the 🐭 invokes the Show State command for you
  • Recognizes if you save any .editorconfig file and reapplies all settings to all opened editor-panes

Example file

root = true

indent_style = tab
indent_size = 3
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

indent_size = 2

trim_trailing_whitespace = false




We're sorry to hear you're having trouble using atom-editorconfig! Please bear some caveats in mind:

  • Why isn't EditorConfig applying the indentation character to my files?
    EditorConfig is not intended to do so; it will apply the indentation char only to new indentations. You may try to fix indentation issues with the EditorConfig: Fix File command.
  • Why is indent_style not working?
    You can set Atom's config setting "Tab Type" to either soft or hard, this prevents EditorConfig from influencing the indentation style. Set Atom's "Tab Type" to auto to allow EditorConfig taking control over the indentation characters.
  • Why is feature X not working?
    Some other packages (e.g. the whitespace package) override the EditorConfig settings. In these cases, we try to alert you about confirmed interferences and suggest that you try disabling the other package. If you face any unreported issues, please let us know.

💡 You can check how EditorConfig affects your current file by invoking the EditorConfig: Show State command. If EditorConfig detects any issues which may prevent it from working properly it displays a 🐭 in the status bar; clicking on it opens the state notification (like the Show State command).
