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!
sargs2multislice
Create a
MultiSlice
object from a comma-separated list of string-serializedMultiSlice
constructor arguments.
Installation
npm install @stdlib/slice-base-sargs2multislice
Usage
var sargs2multislice = require( '@stdlib/slice-base-sargs2multislice' );
sargs2multislice( str )
Create a MultiSlice
object from a comma-separated list of string-serialized MultiSlice
constructor arguments.
var s = sargs2multislice( '0,Slice(2,10,1),1' );
// returns <MultiSlice>
var d = s.data;
// returns [ 0, <Slice>, 1 ]
The function returns null
if provided an invalid string.
var s = sargs2multislice( 'foo,bar' );
// returns null
Notes
-
This function is useful from wanting to create a
MultiSlice
object from an array of constructor arguments which has been serialized to a string (e.g., when working withProxy
objects supporting slicing].var Slice = require( '@stdlib/slice-ctor' ); var args = [ 0, new Slice( 2, 10, 1 ), 1 ]; // ... var sargs = args.toString(); // returns '0,Slice(2,10,1),1' // ... var s = sargs2multislice( sargs ); // returns <MultiSlice> var d = s.data; // returns [ 0, <Slice>, 1 ]
Examples
var sargs2multislice = require( '@stdlib/slice-base-sargs2multislice' );
var s = sargs2multislice( 'null,null,null' );
var d = s.data;
// returns [ null, null, null ]
s = sargs2multislice( '10,Slice(2,10,1),null' );
d = s.data;
// returns [ 10, <Slice>, null ]
s = sargs2multislice( '2,Slice(2,10,1),-5' );
d = s.data;
// returns [ 2, <Slice>, -5 ]
s = sargs2multislice( 'foo,bar' );
// returns null
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.
