The Squirrel programming language, version 3.0.6. This repository is made available with the author's permission.
Squirrel is a high level imperative, object-oriented programming language, designed to be a light-weight scripting language that fits in the size, memory bandwidth, and real-time requirements of applications like video games. Although Squirrel offers a wide range of features like:
- open source MIT licence
- dynamic typing
- delegation
- classes & inheritance
- higher order functions
- lexical scoping
- generators
- cooperative threads (coroutines)
- tail recursion
- exception handling
- automatic memory management (CPU bursts free; mixed approach ref counting/GC)
- both compiler and virtual machine fit together in about 7k lines of C++ code and add only around 100kb-150kb the executable size
- optional 16bits characters strings
- powerful embedding api
- eg. function/classes can be defined by scripts or in C
- eg. objects can fully exist in the VM or be bound to native code
- eg. classes created in C can be extended by scripts or vice-versa
- and more
Squirrel is inspired by languages like Python, Javascript, and especially Lua (the API is very similar and the table code is based on the Lua one)
