Basename

Regular expression to capture the last part of a path.

Usage

var reBasename = require( '@stdlib/regexp/basename' );

reBasename( [platform] )

Returns a regular expression to capture the last part of a path.

var RE = reBasename();
// returns <RegExp>

RE = reBasename( 'posix' );
// returns <RegExp>

var base = RE.exec( '/foo/bar/index.js' )[ 1 ];
// returns 'index.js'

RE = reBasename( 'win32' );
// returns <RegExp>

base = RE.exec( 'C:\\foo\\bar\\index.js' )[ 1 ];
// returns 'index.js'

reBasename.REGEXP

Regular expression to capture the last part of a path.

var bool = ( reBasename.REGEXP.toString() === reBasename().toString() );
// returns true

reBasename.REGEXP_POSIX

Regular expression to capture the last part of a POSIX path.

var base = reBasename.REGEXP_POSIX.exec( '/foo/bar/index.js' )[ 1 ];
// returns 'index.js'

reBasename.REGEXP_WIN32

Regular expression to capture the last part of a Windows path.

var base = reBasename.REGEXP_WIN32.exec( 'C:\\foo\\bar\\index.js' )[ 1 ];
// returns 'index.js'

Notes

The as REGEXP exported regular expression is platform-dependent. If the current process is running on Windows, REGEXP === REGEXP_WIN32; otherwise, REGEXP === REGEXP_POSIX.

Examples

var reBasename = require( '@stdlib/regexp/basename' );
var RE_BASENAME = reBasename();

// Assuming a POSIX platform...
var base = RE_BASENAME.exec( '/foo/bar/index.js' )[ 1 ];
// returns 'index.js'

base = reBasename.REGEXP_POSIX.exec( '/foo/bar/home.html' )[ 1 ];
// returns 'home.html'

base = reBasename.REGEXP_WIN32.exec( 'C:\\foo\\bar\\home.html' )[ 1 ];
// returns 'home.html'
