Remembering the nature of lua's multiple arguments, and the fact that multiple arguments are not returned on a lua table dressed as an array, the description on the manual started to make sense. The select function takes as "index" the index of the first argument that you want to retrieve...
1.1 函数的处理 不管是 "member functions" 或者是 "static functions"的处理, 在bridge库上的实现都比较统一, 整个过程与我们前面提到的函数的类型擦除基本是一致的. c++函数向lua注册的核心目的只有一个: 将需要在lua中调用的c++函数, 转换为 统一类型的lua c function. 剩下的调用过程就比较简单了, 正确填入...
无符号字节字面量。 M multiple arguments/results。多参数与返回值。 除了后缀外,部分指令还会有一些约定俗成的前缀,用来标识指令操作的目标数据的类型。例如: T table。表。 F function。函数。 U UpValue。上值。 K constant。常量。 G global。全局。 例如,指令USETS是为一个UpValue设置字符串值;指令TGETV...
When a function is called, the list of arguments is adjusted to the length of the list of parameters, unless the function is a vararg function, which is indicated by three dots ('...') at the end of its parameter list. A vararg function does not adjust its argument list; instead, it...
int displayLuaFunction(lua_State *l) { // number of input arguments int argc = lua_gettop(l); // print input arguments std::cout << "[C++] Function called from Lua with " << argc << " input arguments" << std::endl; for(int i=0; i ...
it collects all extra arguments and supplies them to the function through a vararg expression, which is also written as three dots. The value of this expression is a list of all actual extra arguments, similar to a function with multiple results. If a vararg expression is used inside another...
It is possible to create functions with variable arguments in Lua using '...' as its parameter. We can get a grasp of this by seeing an example in which the function will return the average and it can take variable arguments. main.lua ...
Lua-eco 是一个内置了事件循环的 Lua 解释器。它能够自动调度轻量级 Lua 协程, 从而实现在 Lua 中的高效并发。使用 Lua-eco 可以构建高性能、可扩展的应用程序。 Lua-eco 还提供了一些有用的模块,方便您快速构建应用程序: log:为 lua-eco 应用程序提供日志功能,允许您以不同的级别打印日志并将其输出到各种目的...
FunctionCommand基于命令入口函数定义一个命令。它是BaseCommand的子类。构造参数除了BaseCommand所支持的字段,还额外支持: entry_func命令入口函数。用于执行该命令本身的业务逻辑。它接受3个参数cmd,options,arguments,分别为命令实例,解析好的命令选项和命令参数。它可以返回一个整数,用于指示执行结果(0表示正常结束,非0...
When there are only three arguments (including the "red" object itself), then the last argument must be a Lua table holding all the field/value pairs.Back to TOCarray_to_hashsyntax: hash = red:array_to_hash(array)Auxiliary function that converts an array-like Lua table into a hash-...
