glob-parent [](https://travis-ci.org/es128/glob-parent) [](https://coveralls.io/r/es128/glob-parent?branch=master)
|
|
======
|
|
Javascript module to extract the non-magic parent path from a glob string.
|
|
|

|

|
Usage
|
|
-----
|
|
```sh
|
|
npm install glob-parent --save
|
|
```
|
|
|
|
**Examples**
|
|
|
|
```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)
|
|
```
|
|
|
|
## 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)
|
|
- `*` (star)
|
|
- `|` (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]*') // '.'
|
|
```
