NSP

NSP: the scripting language for C programmers.

NSP is the complete object-based scripting language written in just a few thousand lines of ANSI C. It's portable, thread-safe, flexible, embeddable, expandable and easy to understand (as a language and as an API). NSP scripts can and often do look very much like JavaScript, but NSP is Not an ECMA Scripting Language.

Download

NSP is free to use and distribute subject to the terms of the GNU GPL.

Run

Using Web Assembly, NSP can run in your web browser! Try it here.

Bugs

If you find a bug, some weird behaviour, or just come up with a cool test script, show me. I want scripts I can use to see the bug in action now, and test for possible recurrences later.
