News
(12/19/2010): Added usermessages, bitbuffers, and SourcePawn native invocation. Fixed a bunch of bugs, thanks to Thraka. There's still a fair bit to complete (reading bitbuffers in hooked usermessages, byref variables in SourcePawn native invocation, and menus), but it's getting closer and closer to completion.

Also added is a testing plug-in and a Python header file output plug-in. The testing plug-in is a bunch of unit tests that help in determining some functionality (there are many untestable things). The header file output plug-in generates a bunch of Python files that contain method and class stubs for use with a Python IDE.

(3/21/2010): Fixed client-side concommands. It seems I never actually hooked OnClientCommand. It's all better now -- at least on Windows. Still working on Linux ;)

(2/8/2010): Fixed plug-in unloading when the plug-in uses multiple threads. This means you can now use the twisted library. Also, now the plugin_unload function will be called on plugin unload.

(2/3/2010): The Windows version is complete! I have written over 70 unit tests and compiled Viper for the ep1, ob, ob-valve, l4d, and l4d2 engines. GRAB IT WHILE IT'S HOT. Unfortunately, the Linux version is still only available on Ep1.

(1/13/2010): I have almost fixed the Windows version, and it should be available for release in the near future!

(1/03/2010): Finally, Viper has limped all the way here. Don't get too excited, because most of his limbs have been torn off. All that he brought with him is a version compiled on Linux for the Episode 1 engine. So, until I can bring him to the operating room to compile the rest (and fix the Windows version), that's all you're going to get.
TL;DR: Viper is only available for Linux on the Ep1 engine for now

Viper
Viper is a SourceMod extension that embeds the CPython interpreter, allowing you to create plug-ins in Python. Its standard library is written completely in C++, so its performance is unrivaled.

Viper is compiled against CPython 2.5.4. A few non-standard modules have been included with Viper:

• twisted
• psyco

Impressive.

Very cool. Your Yak is insanely large.

[psychonic]

Nice to see a released version of that. Your Yak is not insanely large enough.

[DrGamez]

Dumb question: This is only for ep1 engine, so using it for writing TF2 plugins on orange box right now is a no-no, or just doesn't work; right?

I'm super excited to see this project, it's like all my dreams come true.

[theY4Kman]

Yes, that is correct, DrGamez. I apologize for having such a limited release.

[pRED*]

My what large yak you have

Couldn't have said it better myself.

Are there any plans of updating the extension to work with Python 2.6.4, or maybe even Py3k?

Yes, eventually I plan to update to Python 2.6. In fact, I hear devicenull has already compiled against 2.6. As for Py3K, never. I think the changes made to the language make it harder to learn, and that's not what I want on Viper. Even though they did make a lot of changes to the C API that would really help me, I still feel it's a bad idea to release Viper with it. But you're welcome to compile against it

Very cool, shame about not using Python 3k though .

CPython has reference counted GC right? So you won't freeze the game server in the middle of a GC and lag everyone?
