{{alias}}( [platform] )
    Regular expression to split a filename.

    The regular expression is platform-dependent. If the current process is
    running on Windows, the regular expression is `*.REGEXP_WIN32`; otherwise,
    `*.REGEXP_POSIX`.

    Parameters
    ----------
    platform: string (optional)
        Path platform (either `posix` or `win32`).

    Returns
    -------
    re: RegExp
        Regular expression.

    Examples
    --------
    > var RE = {{alias}}()
    <RegExp>
    > var RE_POSIX = {{alias}}( 'posix' );
    > var parts = RE_POSIX.exec( '/foo/bar/index.js' ).slice()
    <Array>
    > var RE_WIN32 = {{alias}}( 'win32' );
    > parts = RE.exec( 'C:\\foo\\bar\\index.js' ).slice()
    <Array>
    > var str = RE.toString();
    > var bool = ( str === RE_POSIX.toString() || str === RE_WIN32.toString() )
    true


{{alias}}.REGEXP
    Regular expression to split a filename.

    Examples
    --------
    > var RE = {{alias}}.REGEXP
    <RegExp>

    following parts:

    - input value
    - root
    - dirname
    - basename
    - extname

    Examples
    --------
    > var f = '/foo/bar/index.js';
    > var parts = {{alias}}.REGEXP_POSIX.exec( f ).slice()
    [ '/foo/bar/index.js', '/', 'foo/bar/', 'index.js', '.js' ]


{{alias}}.REGEXP_WIN32
    Regular expression to split a Windows filename.

    When executed, the regular expression splits a Windows filename into the
    following parts:

    - input value
    - device
    - slash
    - dirname
    - basename
    - extname

    Examples
    --------
    > var f = 'C:\\foo\\bar\\index.js';
    > var parts = {{alias}}.REGEXP_WIN32.exec( f ).slice()
    [ 'C:\\foo\\bar\\index.js', 'C:', '\\', 'foo\\bar\\', 'index.js', '.js' ]
