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!

pkg2alias

Return the alias associated with a specified package name.

Installation

npm install @stdlib/namespace-pkg2alias

Usage

var pkg2alias = require( '@stdlib/namespace-pkg2alias' );

pkg2alias( pkg )

Returns the alias associated with a specified package name.

var v = pkg2alias( '@stdlib/math-base-special-sin' );
// returns 'base.sin'

If provided an unrecognized pkg, the function returns null.

var v = pkg2alias( 'unrecognized_pkg_beep_boop_bop_bip' );
// returns null

Notes

• The function supports providing both internal and standalone package names.

  var v = pkg2alias( '@stdlib/math-base-special-sin' );
  // returns 'base.sin'

Examples

var discreteUniform = require( '@stdlib/random-base-discrete-uniform' );
var aliases = require( '@stdlib/namespace-aliases' );
var alias2pkg = require( '@stdlib/namespace-alias2pkg' );
var pkg2alias = require( '@stdlib/namespace-pkg2alias' );

var list;
var len;
var idx;
var v1;
var v2;
var i;

list = aliases();
len = list.length;

// Round-trip from alias-to-pkg-to-alias...
for ( i = 0; i < 100; i++ ) {
    idx = discreteUniform( 0, len-1 );
    v1 = alias2pkg( list[ idx ] );
    v2 = pkg2alias( v1 );
    console.log( 'alias: %s. pkg: %s.', list[ idx ], v1 );
    console.log( 'pkg: %s. alias: %s.', v1, v2 );
}
