Generate .editorconfig

When to use this skill

When starting work on a new repository or adding an .editorconfig to an existing project that lacks one.

How it works

Creates a minimal .editorconfig file with sensible defaults. The generated config follows the repository's existing style when possible.

Process

1. •Check if .editorconfig already exists - if so, update it
2. •Examine existing files in the repo to detect coding style:
   • •Look at indentation (spaces vs tabs), indent size
   • •Check line ending conventions
   • •Identify file types that may need special handling
3. •Generate appropriate, minimal .editorconfig content with no unnecessary duplication.
4. •Write the file to the repository root

Generated Config Structure

root = true

[*]
indent_style = space
indent_size = <detected or 4>
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.md]
max_line_length = 78

[*.json]
indent_size = 2

Best Practices

• •Always set root = true at the top
• •Use [*] for universal settings
• •Add specific file type overrides after universal settings
• •Keep it minimal - only specify what differs from editor defaults
