@stdlib/slice-base-sargs2multislice NPM

sargs2multislice

Create a MultiSlice object from a comma-separated list of string-serialized MultiSlice 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 with Proxy 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.
