Package Exports

@stdlib/regexp-extname-windows

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-extname-windows) 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 Windows filename extension.

Installation

npm install @stdlib/regexp-extname-windows

Usage

var reExtnameWindows = require( '@stdlib/regexp-extname-windows' );

reExtnameWindows()

Returns a regular expression to capture a Windows filename extension.

var RE_EXTNAME_WINDOWS = reExtnameWindows();
var ext = RE_EXTNAME_WINDOWS.exec( 'index.js' )[ 1 ];
// returns '.js'

reExtnameWindows.REGEXP

Regular expression to capture a Windows filename extension.

var ext = reExtnameWindows.REGEXP.exec( 'C:\\foo\\bar\\index.js' )[ 1 ];
// returns '.js'

Notes

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

var ext = reExtnameWindows.REGEXP.exec( '.bash_profile' )[ 1 ];
// returns ''

ext = reExtnameWindows.REGEXP.exec( '.travis.yml' )[ 1 ];
// returns '.yml'

Examples

var reExtnameWindows = require( '@stdlib/regexp-extname-windows' );

var RE_EXTNAME_WINDOWS = reExtnameWindows();
var ext;

ext = RE_EXTNAME_WINDOWS.exec( 'index.js' )[ 1 ];
// returns '.js'

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

ext = RE_EXTNAME_WINDOWS.exec( 'foo\\file.pdf' )[ 1 ];
// returns '.pdf'

ext = RE_EXTNAME_WINDOWS.exec( 'beep\\boop.' )[ 1 ];
// returns '.'

ext = RE_EXTNAME_WINDOWS.exec( '' )[ 1 ];
// returns ''

ext = RE_EXTNAME_WINDOWS.exec( '\\foo\\bar\\file' )[ 1 ];
// returns ''

ext = RE_EXTNAME_WINDOWS.exec( 'C:\\foo\\bar\\.gitignore' )[ 1 ];
