xaliphostes

A small multi-threaded C++ library (so, does not include any main) compiled with emscripten and pthread running under the main thread in the browser, a web worker or using node.js.

Note: Emscripten will produce lib.js.

Using a web browser

Running this lib in the main thread is fine but, obviously, block the main thread. Running it using a web worker leads no error with modification of the worker script (see below)

Using node.js

Run fine except that it prevents Node app from ever exiting.

Reproduces RxJs behavior

There is no generic operators as in RxJs yet, but the main idea behind is presented here...

Wrapping C++ for Python

Your project

1. You should have the CMakeFiles.txt and the src folder to start.

The CMakeFiles.txt:

cmake_minimum_required(VERSION 3.4...3.18)
project(pimymath)

const forEach = (as, cb) => {
  // necessary tests:
  //   - as is an array and all items in as are arrays
  //   - length of all arrays in as are the same
  as[0].forEach( (serie, i) => cb( as.map( serie => serie[i] ), i, as) )
}

// ---------------- testing

const A = [1, 2, 3, 4]

xaliphostes

const zip = arrays => {
    return Array.apply(null, Array(arrays[0].length)).map( (_,i) =>  arrays.map( array => array[i] ) )
}

// ----------- testing

const A = [1, 2, 3, 4]
const B = [5, 6, 7, 8]
const C = [9, 4, 3, 2]
