.editorconfig File — EditorConfig File

EditorConfig files define and maintain consistent coding styles across different editors and IDEs used by multiple developers on a project. The .editorconfig file uses an INI-like format with sections defined by glob patterns that match file paths, and properties that specify formatting preferences for those files. Supported properties include indent_style (tab/space), indent_size, end_of_line (lf/crlf/cr), charset, trim_trailing_whitespace, insert_final_newline, and max_line_length. EditorConfig is supported natively or via plugins by virtually every code editor including VS Code, IntelliJ IDEA, Sublime Text, Atom, Visual Studio, vim, Emacs, and many others. When a file is opened, the editor searches up the directory tree for .editorconfig files, applying settings from the nearest file with root = true stopping the search. This hierarchy allows project-level defaults with directory-specific overrides. EditorConfig solves a real collaboration problem — ensuring that files maintain consistent formatting regardless of each developer's personal editor settings. The format is widely adopted in open-source projects and has become a standard part of professional development workflows alongside linters and formatters.
