Filename

Regular expression to split a POSIX filename.

Usage

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

RE_FILENAME_POSIX

Regular expression to split a POSIX filename.

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
    ]
*/

Notes

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

    var parts = RE_FILENAME_POSIX.exec( '.bash_profile' ).slice();
    /* returns
      [
          '.bash_profile',
          '',
          '',
          '.bash_profile',
          ''
      ]
    */
    
    parts = RE_FILENAME_POSIX.exec( '.travis.yml' ).slice();
    /* returns
      [
          '.travis.yml',
          '',
          '',
          '.travis.yml',
