pypy's Introduction

PyPy.js: PyPy compiled into JavaScript

Note: Development is sleeping at the moment. Discuss this here: #213. Look at iodide (specifically, pyodide) for a maintained and heavily developed alternative.

PyPy. Compiled into JavaScript. JIT-compiling to JavaScript at runtime. Because why not.

This is a very-much-in-flux collection of supporting scripts and infrastructure for an experimental emscripten/asmjs backend for PyPy. You can read more about the project (and try it out live!) here:

http://pypyjs.org/

If you just want to use a pre-compiled PyPy.js interpreter, please download a release bundle from the above website and follow the instructions in the included README.

If you're like to work on the PyPy.js code itself, please see the details in CONTRIBUTING.rst. All code is available under the MIT License.

For the history of the project, see NEWS.

pypy's Issues

Adding a function to the js module

I've been working on getting the pypy vm built with emterpreter enabled to get synchronous functions to work. I've added a function to the js module to synchronously await a promise.

But now I'm running into a compile error that I can't figure out.

This is the error: (I'll add the stacktrace to the end)

[translation:ERROR] ValueError: argument to ll function pointer call: should return a low-level type,
[translation:ERROR] got instead SomeInstance(can_be_None=True, classdef=pypy.interpreter.baseobjspace.W_Root)

I added this to emjs.h

//Synchronously await a promise
emjs_handle emjs_await(emjs_handle promise);

and then this to library_emjs.js

  emjs_await__deps: ['emjs_deref', '$EmterpreterAsync'],
  emjs_await: function(promise_h) {
    var promise = _emjs_deref(promise_h);
    EmterpreterAsync.handle(function(resume) {
      promise.then(function(val) {
        if (ABORT) return;  
        resume(val);
      }, function(err) {
        if (ABORT) return;
        EMJS.last_error = err;
        resume(EMJS.ERROR);
      });
    });
  },

And this to support.py (what does random_effects_on_gcobjs mean?)

@jsexternal([EMJS_HANDLE_TP], EMJS_HANDLE_TP,
            random_effects_on_gcobjs=True)
def emjs_await(h_prom):
    raise NotImplementedError

I added this to interp_js.py

def await(space, w_promise): 
    """Await a javascript promise."""
    h = support.emjs_await(w_promise)
    return _wrap_handle(space, h)

And this to init.py: 'await': 'interp_js.await'

stacktrace:

add changes in a seperate branch?!?

It's not directly clear what changes for PyPy.js was made.

What's about to made all changes in a separate branch? So it's possible to use the github compare view ;)

compiling python3 error

When I compile the python 3 version, the report is wrong translate: error: invalid value javascript for option backend and translate: error: invalid value js for option backend

How do I compile the python 3 version of the pypyjs file correctly?

py3k branch missing

Hey @rfk I opened an issue about this somewhere but I can't find it anymore. I just wanted to give a very gentle reminder that you were going to push the py3k branch for pypy to this repo. Thanks!

Error: expected string, got String object

getattr(a js object, attr_name) seems not to work as excepted.

Test code:

import js

jquery = js.globals["$"]
print "isReady 1:", jquery.isReady
print "isReady 2:", getattr(jquery, "isReady")

for attr_name in jquery:
    print "%20s:" % attr_name,
    try:
        print getattr(jquery, attr_name)
    except Exception as err:
        print "Error: %s" % err

will output:

isReady 1: true
isReady 2: true
                  fn: Error: expected string, got String object
              extend: Error: expected string, got String object
             expando: Error: expected string, got String object
          noConflict: Error: expected string, got String object
             isReady: Error: expected string, got String object
