 | 
						|
 | 
						|
Extract the non-magic parent path from a glob string.
 | 
						|
 | 
						|
## Usage
 | 
						|
 | 
						|
```js
 | 
						|
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
 | 
						|
 | 
						|
```js
 | 
						|
{
 | 
						|
  // 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**
 | 
						|
 | 
						|
```js
 | 
						|
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.
 | 
						|
 | 
						|
```js
 | 
						|
// 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.
 | 
						|
 | 
						|
```js
 | 
						|
// BAD
 | 
						|
globParent('foo \\[bar]') // 'foo '
 | 
						|
globParent('foo \\[bar]*') // 'foo '
 | 
						|
 | 
						|
// GOOD
 | 
						|
globParent('./foo \\[bar]') // 'foo [bar]'
 | 
						|
globParent('./foo \\[bar]*') // '.'
 | 
						|
```
