EditorConfig

EditorConfig helps developers maintain consistent coding styles between different editors.

Install

$ apm install editorconfig

Or, Settings → Install → Search for editorconfig

Getting started

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

Open a project containing an .editorconfig file.
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.
EditorConfig then applies these settings to your current editor pane. Any change you make from now on will follow the EditorConfig settings. EditorConfig won't automatically fix older files that it considers to be malformed.
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

root
indent_style
indent_size / tab_width (indent_size takes precedence over tab_width)
charset (supported values: latin1, utf-8, utf-16be, utf-16le)
end_of_line (supported values: lf, crlf)
trim_trailing_whitespace (supported values: true, false)
insert_final_newline (supported values: true, false; Setting this to false strips final newlines)
max_line_length

💡 Any malformed or missing property is set to auto which leaves the control to Atom.

EditorConfig commands

EditorConfig: Fix File: Fixes indent_style and end_of_line issues for the current editor.
EditorConfig: Show State: Shows the current state of EditorConfig for your current editor.
EditorConfig: Generate Config: Generates an initial .editorconfig for your project.

Features

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)
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

[*.{json,yml}]
indent_size = 2

[*.md]
trim_trailing_whitespace = false

Troubleshooting

We're sorry to hear you're having trouble using atom-editorconfig! However, 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. However, you may try to fix indentation issues with the EditorConfig: Fix File command.
Why is indent_style not working? Your Atom's config setting "Tab Type" might be set to either soft or hard, this unfortunately prevents EditorConfig from influencing the indentation style. Set Atom's "Tab Type" to auto to fix that.
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 a 🐭 will be shown in the status bar; clicking on it also opens the state notification.
