    Filename Extension

    NPM version Build Status Coverage Status dependencies

    Regular expression to capture a filename extension.

    Installation

    npm install @stdlib/regexp-extname

    Usage

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

    reExtname( [platform] )

    Returns a regular expression to capture a filename extension.

    var RE = reExtname();
    // returns <RegExp>
    
    RE = reExtname( 'posix' );
    // returns <RegExp>
    
    var ext = RE.exec( '/foo/bar/index.js' )[ 1 ];
    // returns '.js'
    
    RE = reExtname( 'win32' );
    // returns <RegExp>
    
    ext = RE.exec( 'C:\\foo\\bar\\index.js' )[ 1 ];
    // returns '.js'

    reExtname.REGEXP

    Regular expression to capture a filename extension.

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

    reExtname.REGEXP_POSIX

    Regular expression to capture a POSIX filename extension.

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

    reExtname.REGEXP_WIN32

    Regular expression to capture a Windows filename extension.

    var ext = reExtname.REGEXP_WIN32.exec( 'C:\\foo\\bar\\index.js' )[ 1 ];
    // returns '.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 reExtname = require( '@stdlib/regexp-extname' );
    var RE_EXTNAME = reExtname();
    var ext;
    
    // Assuming a POSIX platform...
    ext = RE_EXTNAME.exec( '/foo/bar/index.js' )[ 1 ];
    // returns '.js'
    
    ext = reExtname.REGEXP_WIN32.exec( '/foo/bar/home.html' )[ 1 ];
    // returns '.html'
    
    ext = reExtname.REGEXP_WIN32.exec( 'C:\\foo\\bar\\home.html' )[ 1 ];
    // returns '.html'
