About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
reBasename
Regular expression to capture the last part of a path.
Installation
npm install @stdlib/regexp-basename
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'
Notice
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
