Terra低级系统编程语言

Terra 是一个新的低级系统编程语言,旨在实现无缝的与Lua编程语言协作。

示例代码：

-- This top-level code is plain Lua code.
print("Hello, Lua!")

-- Terra is backwards compatible with C
-- we'll use C's io library in our example.
C = terralib.includec("stdio.h")

-- The keyword 'terra' introduces
-- a new Terra function.
terra hello(argc : int, argv : &rawstring)
    -- Here we call a C function from Terra
    C.printf("Hello, Terra!\n")
    return 0
end

-- You can call Terra functions directly from Lua
hello(0,nil)

-- Or, you can save them to disk as executables or .o
-- files and link them into existing programs
terralib.saveobj("helloterra",{ main = hello })
