Package Exports

@stdlib/regexp-filename-posix

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/regexp-filename-posix) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Filename

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();
var parts = RE_FILENAME_POSIX.exec( 'index.js' ).slice();

        '',
        '',
        'index.js',

    ]
*/

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

        '/',
        'foo/bar/',
        'home.html',
        '.html'
    ]
*/

parts = RE_FILENAME_POSIX.exec( 'foo/file.pdf' ).slice();
/* returns
    [
        'foo/file.pdf',
        '',
        'foo/',
        'file.pdf',
        '.pdf'

parts = RE_FILENAME_POSIX.exec( 'beep/boop.' ).slice();
/* returns
    [
        'beep/boop.',
        '',
        'beep/',
        'boop.',
        '.'
    ]
*/

parts = RE_FILENAME_POSIX.exec( '' ).slice();
/* returns
    [
        '',
        '',
        '',
        '',

        '/',
        'foo/bar/',
        'file',

    ]
*/

parts = RE_FILENAME_POSIX.exec( '/foo/bar/.gitignore' ).slice();
/* returns
    [
        '/foo/bar/.gitignore',
        '/',
        'foo/bar/',
