Package Exports

regex-extname

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 (regex-extname) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Filename Extension

Regular expression to capture a filename extension.

Installation

$ npm install regex-extname

Usage

var re = require( 'regex-extname' );

re

Regular expression to capture a filename extension.

var ext;

// On a POSIX platform...
ext = re.exec( '/foo/bar/index.js' )[ 1 ];
// returns '.js'

// On a Windows platform...
ext = re.exec( 'C:\\foo\\bar\\index.js' )[ 1 ];
// returns '.js'

re.posix

Regular expression to capture a POSIX filename extension.

re.win32

Regular expression to capture a Windows filename extension.

Notes

The main exported [regular expression](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) is [platform](https://github.com/kgryte/node-check-if-windows)-dependent. If the current process is running on Windows, `re === re.win32`; otherwise, `re === re.posix`.

Examples

var re = require( 'regex-extname' );

var ext;

// Assuming a POSIX platform...
ext = re.exec( '/foo/bar/index.js' )[ 1 ];
console.log( ext );
// returns '.js'

ext = re.posix.exec( '/foo/bar/home.html' )[ 1 ];
console.log( ext );
// returns '.html'

ext = re.win32.exec( 'C:\\foo\\bar\\home.html' )[ 1 ];
console.log( ext );
// returns '.html'

To run the example code from the top-level application directory,
