reFilenameWindows

Regular expression to split a Windows filename.

Installation

npm install @stdlib/regexp-filename-windows

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'
    ]
  */

        'file',
        ''
    ]
*/

parts = RE_FILENAME_WINDOWS.exec( 'C:\\foo\\bar\\.gitignore' ).slice();
/* returns
