f_parser调用luaY_parser分析,并初始化Upvalues(外局部变量)。 luaY_parser 使用LexState包裹FuncState调用luaX_next进行进一步分析,其结果保存到Proto结构的code数组中,传递给LClosure并推入栈中。 luaX_next循环分析,依据词法,语法规则调用luaK_code生成字节码。 部分代码: static void statement (LexState *ls) ...
在f_parser中根据一些选择来分别处理不同的情况,我们示例中会跑到luaY_parser函数中去,在luaY_parser中会调用luaX_next进行分析,这个函数会首先读取源文件中的第一个token 最后在luaX_next中调用了llex,llex是真正切出token的例程 在读取了第一个token后luaX_next返回,相关的词法信息保存在了lexstate中,接着lua...

If you’re getting bored at this point, I suggest you skip to iteration 3. Segfaults and Valgrind That was the design for iteration 1. But the __parent made it complicated, because I had to create the cache-array by recursing backwards into all the node’s ancestors. This complexity hi...
Iteration over Python objects from Lua's for-loop is fully supported. However, Python iterables need to be converted using one of the utility functions which are described here. This is similar to the functions like pairs() in Lua. To iterate over a plain Python iterable, use the python....
Will skip the current loop iteration. push keyword function a() for i=1, 5 do push i, "next" end return "done" end print(a()) -- 1, next, 2, next, 3, next, 4, next, 5, next, done push "hey" -- Does *not* work, because it is a valid Lua syntax for push("hey") ...
If skipfirst is true then this function will not draw anything at the pixel x1,y1, otherwise it will. skipfirst is optional and defaults to false. The default color for the line is solid white, but you may optionally override that using a color of your choice. See also drawing notes ...
As before, we save the bonusType in lower case, since we'll be using it a lot later. Next, we open a for loop, where the index is the id of the unit type receiving the bonus, and the value is the bonus table for that unit type. Next, we duplicate the bonus tabl...
