## Usage
|
|
|
|
```javascript
|
|
var reFilenamePosix = require( '@stdlib/regexp/filename-posix' );
|
|
```
|
|
|
|
#### reFilenamePosix()
|
|
|
|
Returns a [regular expression][mdn-regexp] to split a [POSIX][posix] filename.
|
|
|
|
```javascript
|
|
var RE_FILENAME_POSIX = reFilenamePosix();
|
|
var parts = RE_FILENAME_POSIX.exec( '/foo/bar/index.js' ).slice();
|
|
/* returns
|
|
[
|
|
'/foo/bar/index.js', // input value
|
|
'/', // root
|
|
'foo/bar/', // dirname
|
|
'index.js', // basename
|
|
'.js' // extname
|
|
]
|
|
*/
|
|
```
|
|
|
|
#### reFilenamePosix.REGEXP
|
|
|
|
[Regular expression][mdn-regexp] to split a [POSIX][posix] filename.
|
|
|
|
```javascript
|
|
var parts = reFilenamePosix.REGEXP.exec( '/foo/bar/index.js' ).slice();
|
|
/* returns
|
|
[
|
|
'/foo/bar/index.js', // input value
|
|
'/', // root
|
|
'foo/bar/', // dirname
|
|
'index.js', // basename
|
|
'.js' // extname
|
|
]

|
## Notes
|
|
|
|
- When executed against dotfile filenames (e.g., `.gitignore`), the [regular expression][mdn-regexp] does **not** capture the basename as a filename extension.
|
|
|
|
```javascript
|
|
var parts = reFilenamePosix.REGEXP.exec( '.bash_profile' ).slice();
|
|
/* returns
|
|
[
|
|
'.bash_profile',
|
|
'',
|
|
'',
|
|
'.bash_profile',
|
|
''
|
|
]
|
|
*/
|
|
|
|
parts = reFilenamePosix.REGEXP.exec( '.travis.yml' ).slice();
|
|
/* returns
|
|
[
|
|
'.travis.yml',
|
|
'',
|
|
'',
|
|
'.travis.yml',
|
|
'.yml'
|
|
]
