游戲編程語言 Squirrel

Squirrel 是一種高層次勢在必行/面向對象編程語言，設計是一個強大的腳本工具，適合的大小，內存帶寬，實時性要求的應用，如游戲。它具有以下特性：

• 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)

示例代碼

local table = {
    a = "10"
    subtable = {
        array = [1,2,3]
    },
    [10 + 123] = "expression index"
}

local array=[ 1, 2, 3, { a = 10, b = "string" } ];

foreach(i,val in array)
{
    ::print("the type of val is"+typeof val);
}
