EditorConfig File Format

EditorConfig File Format

EditorConfig files use an INI format that is compatible with the format used by Python ConfigParser Library, but [ and ] are allowed in the section names. The section names are filepath globs, similar to the format accepted by gitignore. Forward slashes (/) are used as path separators and semicolons (;) or octothorpes (#) are used for comments. Comments should go individual lines. EditorConfig files should be UTF-8 encoded, with either CRLF or LF line separators.

Filename globs containing path separators (/) match filepaths in the same way as the filename globs used by .gitignore files. Backslashes (\) are not allowed as path separators.

A semicolon character (;) starts a line comment that terminates at the end of the line. Line comments and blank lines are ignored when parsing. Comments may be added to the ends of non-empty lines. An octothorpe character (#) may be used instead of a semicolon to denote the start of a comment.

Filename and Location

When a filename is given to EditorConfig a search is performed in the directory of the given file and all parent directories for an EditorConfig file (named '.editorconfig' by default). All found EditorConfig files are searched for sections with section names matching the given filename. The search will stop if an EditorConfig file is found with the root property set to true or when reaching the root filesystem directory.

Files are read top to bottom and the most recent rules found take precedence. If multiple EditorConfig files have matching sections, the rules from the closer EditorConfig file are read last, so properties in closer files take precedence.

Wildcard Patterns

Section names in EditorConfig files are filename globs that support pattern matching through Unix shell-style wildcards. These filename globs recognize the following as special characters for wildcard matching:

  *            Matches any string of characters, except path separators (/)

**           Matches any string of characters

?            Matches any single character

[seq]        Matches any single character in seq

[!seq]       Matches any single character not in seq

{s1,s2,s3}   Matches any of the strings given (separated by commas, can be nested)

{num1..num2} Matches any integer numbers between num1 and num2, where num1 and num2 can be either positive or negative

The backslash character () can be used to escape a character so it is not interpreted as a special character.

The maximum length of a section name is 4096 characters. All sections exceeding this limit are ignored.

Supported Properties

EditorConfig file sections contain properties, which are name-value pairs separated by an equal sign (=). EditorConfig plugins will ignore unrecognized property names and properties with invalid values.

Here is the list of all property names understood by EditorConfig and all valid values for these properties:

For any property, a value of 'unset' is to remove the effect of that property, even if it has been set before. For example, add 'indent_size = unset' to undefine indent_size property (and use editor default).

Property names are case insensitive and all property names are lowercased when parsing. The maximum length of a property name is 50 characters and the maximum length of a property value is 255 characters. Any property beyond these limits would be ignored.
