Lua 5.2 implemented in pure C#. Hard forked from UniLua. For more examples, see the Test folder.

public void Test()
{
    var L = Lua.New();
    L.OpenLibs(); // or L.OpenSafeLibs();
    L.SetGlobal("AddFromCS", AddFromCs);
    
    L.DoString(
        """
        local a, b = 1, 2
        return AddFromCS(a, b);
        """);

    var r = L.PopInteger();
    Assert.Equal(3, r);
}

private static int AddFromCs(LuaState L)
{
    var a = L.ToInteger(1);
    var b = L.ToInteger(2);
    L.PushInteger(a + b);
    return 1;
}

CSLua is fork of UniLua. I needed a Lua interpreter compatible with AoT C# and as efficient as possible. Unfortunately most libraries don't make the cut due to being focused on unity or allocating too much garbage. This project is a big refactoring of the original code. @Xebecnan's UniLua targets version 5.2 but it also includes some 5.3 features such as utf8 support and integers.

In specific, the differences between my fork and the original are:

  • Code refactoring: Remove references to unity, create new folders.
  • Performance improvements: Converted code to use structs and spans where it makes sense. For example, StkId is no longer a class but a ref to TValue.
  • Added Tests: Including some of the basic Lua 5.2 test suite.
  • Implement some functions of the standard library that were missing: This is still incomplete.
  • Added some power patches: Compound assignments (+=, -=, ..= and friends), continue, != alias for ~=, digit separators (1_000), implicit pairs (for i, v in {1, 2, 3} do ...).
  • First class citizen support for lists:
local list = require 'list'
local list1 = list.new(1, 2, 3)
list1[0] = 2
assert(list1[0] == 2)
assert(#list1 == 3)
list.add(list1, 4)
assert(#list1 == 4)
  • bool concatenation:
local concat = 'foo' .. true -- footrue
  • string concatenation with the + operator:
local concat = 'foo' + true -- footrue
  • C-style comments:
local foo=1 // Call the police
local bar=2 /* Now */

While this library is functional, expect some bugs. Some of lua's tests were disabled due to differences in the implementation or incomplete standard library. You can find them by grepping CSLUA_FAIL in the test/suite folder. Don't expect a stable API.
