reExtnameWindows
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 ];
// returns ''
