goesque 0.1.0

Patch Python function objects with a gevent-backed go() helper.

goesque

goesque patches Python function objects with a go() method backed by gevent.spawn, so regular functions can be launched in a Go-like style.

Quick example

import goesque

goesque.patch_all()

def side_effect():
    print("Side effect!")

side_effect.go()
# out: Side effect!

How it works

goesque.patch_all() does two things:

1. Calls gevent.monkey.patch_all() so standard library I/O becomes cooperative.
2. Patches types.FunctionType so every Python function gains a go() method.

The patching is process-wide for the current interpreter. After patching, any new or existing Python function object can call .go(...).

How go() is implemented

The go() method is installed at runtime and is equivalent to:

def go(self, *args, **kwargs):
    import gevent
    greenlet = gevent.spawn(self, *args, **kwargs)
    gevent.sleep(0)  # yield once so spawned work can start promptly
    return greenlet

Notes:

• go() returns a gevent Greenlet.
• Use join() or get() when you need to wait for completion.
• This is cooperative concurrency (greenlets), not native thread-based parallelism.
