Dirname

Regular expression to capture a path dirname.

Usage

var reDirname = require( '@stdlib/regexp/dirname' );

reDirname( [platform] )

Returns a regular expression to capture a path dirname.

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

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

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

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

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

reBasename.REGEXP

Regular expression to capture a path dirname.

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

reDirname.REGEXP_POSIX

Regular expression to capture a POSIX path dirname.

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

reDirname.REGEXP_WIN32

Regular expression to capture a Windows path dirname.

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

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 reDirname = require( '@stdlib/regexp/dirname' );
var RE_DIRNAME = reDirname();
var dir;

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

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

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