Filename

Regular expression to split a Windows filename.

Usage

var reFilenameWindows = require( '@stdlib/regexp/filename-windows' );

reFilenameWindows()

Returns a regular expression to split a Windows filename.

var RE_FILENAME_WINDOWS = reFilenameWindows(); 
var parts = RE_FILENAME_WINDOWS.exec( 'C:\\foo\\bar\\index.js' ).slice();
/* returns
    [
        'C:\\foo\\bar\\index.js',  // input value
        'C:',                      // device
        '\\',                      // slash
        'foo\\bar\\',              // dirname
        'index.js',                // basename
        '.js'                      // extname
    ]
*/

reFilenameWindows.REGEXP

Regular expression to split a Windows filename.

var parts = reFilenameWindows.REGEXP.exec( 'C:\\foo\\bar\\home.html' ).slice();
/* returns
    [
        'C:\\foo\\bar\\home.html',
        'C:'
        '\\',
        'foo\\bar\\',
        'home.html',
        '.html'
    ]
*/

Notes

When executed against dotfile filenames (e.g., .gitignore), the regular expression does not capture the basename as a filename extension.

var parts = reFilenameWindows.REGEXP.exec( '.bash_profile' ).slice();
/* returns
  [
      '.bash_profile',
      '',
      '',
      '',
      '.bash_profile',
      ''
  ]
*/

parts = reFilenameWindows.REGEXP.exec( '.travis.yml' ).slice();
/* returns
  [
      '.travis.yml',
      '',
      '',
      '',
      '.travis.yml',
      '.yml'
  ]
*/
