glob-parent

glob-parent

Extract the non-magic parent path from a glob string.

Usage

var globParent = require('glob-parent'); globParent('path/to/*.js'); // 'path/to' globParent('/root/path/to/*.js'); // '/root/path/to' globParent('/*.js'); // '/' globParent('*.js'); // '.' globParent('**/*.js'); // '.' globParent('path/{to,from}'); // 'path' globParent('path/!(to|from)'); // 'path' globParent('path/?(to|from)'); // 'path' globParent('path/+(to|from)'); // 'path' globParent('path/*(to|from)'); // 'path' globParent('path/@(to|from)'); // 'path' globParent('path/**/*'); // 'path' // if provided a non-glob path, returns the nearest dir globParent('path/foo/bar.js'); // 'path/foo' globParent('path/foo/'); // 'path/foo' globParent('path/foo'); // 'path' (see issue #3 for details)

API

globParent(maybeGlobString, [options])

Takes a string and returns the part of the path before the glob begins. Be aware of Escaping rules and Limitations below.

options

{ // Disables the automatic conversion of slashes for Windows flipBackslashes: true; }

Escaping

The following characters have special significance in glob patterns and must be escaped if you want them to be treated as regular path characters:

• ? (question mark) unless used as a path segment alone
• * (asterisk)
• | (pipe)
• ( (opening parenthesis)
• ) (closing parenthesis)
• { (opening curly brace)
• } (closing curly brace)
• [ (opening bracket)
• ] (closing bracket)

Example

globParent('foo/[bar]/'); // 'foo' globParent('foo/\\[bar]/'); // 'foo/[bar]'

Limitations

Braces & Brackets

This library attempts a quick and imperfect method of determining which path parts have glob magic without fully parsing/lexing the pattern. There are some advanced use cases that can trip it up, such as nested braces where the outer pair is escaped and the inner one contains a path separator. If you find yourself in the unlikely circumstance of being affected by this or need to ensure higher-fidelity glob handling in your library, it is recommended that you pre-process your input with expand-braces and/or expand-brackets.

Windows

Backslashes are not valid path separators for globs. If a path with backslashes is provided anyway, for simple cases, glob-parent will replace the path separator for you and return the non-glob parent path (now with forward-slashes, which are still valid as Windows path separators).

This cannot be used in conjunction with escape characters.

// BAD globParent('C:\\Program Files \\(x86\\)\\*.ext'); // 'C:/Program Files /(x86/)' // GOOD globParent('C:/Program Files\\(x86\\)/*.ext'); // 'C:/Program Files (x86)'

If you are using escape characters for a pattern without path parts (i.e. relative to cwd), prefix with ./ to avoid confusing glob-parent.

// BAD globParent('foo \\[bar]'); // 'foo ' globParent('foo \\[bar]*'); // 'foo ' // GOOD globParent('./foo \\[bar]'); // 'foo [bar]' globParent('./foo \\[bar]*'); // '.'
