Include native C++ function at runtime in Javascript?

[manne...@gmail.com]

Hey guys,
is it possible to include native C functions at runtime in my Javascript like it works at Node.js?
For example: var express = require('express');

And if it's possible can you give an example?

As far as I know, this is not possible, may be the self-hosting modification
made recently made that possible.

Till, do you have any idea about that?

FWIW, this is exactly the type of problem
http://code.google.com/p/gpseewas created to solve.... provided you
are in a JS embedding environment,
not trying to do this from the browser!

Typo in the URL : http://code.google.com/p/gpsee

BTW, what's the problem with that? You just have to bind an object to a
JSNative or a container at runtime (either by dynamically loading a
library or already loaded binary).

gpsee abstract this to make it easier.

If you can live with an older version of SpiderMonkey, you can use GPSEE
for this pretty easily. It's GPSEE's primary design goal.

There are many ways, depending on need. The simplest case, which addresses
90% of needs IME, is to use the gffi module.

#! /usr/bin/gsr
var GFFI = require("gffi");
var puts = new GFFI.CFunction(GFFI.int, "puts", GFFI.pointer);

puts("Hello, World");
