reFilenamePosix

Regular expression to split a POSIX filename.

Installation

npm install @stdlib/regexp-filename-posix

Usage

var reFilenamePosix = require( '@stdlib/regexp-filename-posix' );

reFilenamePosix()

Returns a regular expression to split a POSIX filename.

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 to split a POSIX filename.

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 does not capture the basename as a filename extension.

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'
  ]
*/

Examples

var reFilenamePosix = require( '@stdlib/regexp-filename-posix' );

var RE_FILENAME_POSIX = reFilenamePosix();

        '',

parts = RE_FILENAME_POSIX.exec( '/foo/bar/home.html' ).slice();
/* returns
