第一,数据for循环: for var=exp1,exp2,exp3 do loop-part end 1. 2. 3. for将用exp3作为step从exp1(初始值)到exp2(终止值),执行loop-part。其中exp3可以省略.默认step=1 有几点需要注意: 三个表达式只会被计算一次,并且是在循环开始前。 控制变量var时局部变量自动被声明,并且只在循环内有效。 循环...

79 other wise it will go out of scope and disappear when a lexicalblock enclosing the local variable ends. 80 CLOSE performs this operation for all affected local variables for do end blocks or loop blocks. 81 RETURN also does an implicit CLOSE when a function returns.*/ 82 OP_CLOSE,/* ...
Lua doesn't have a dedicated syntax for named arguments, so by default Python callables can only be called using positional arguments. A common pattern for implementing named arguments in Lua is passing them in a table as the first and only function argument. See http://lua-users.org/wiki...
end false for function if in local nil not or repeat return then true until while Lua 是一个大小写敏感的语言:and是一个保留字,但是And和AND则是两个不同的合法的名字。 一般约定,以下划线开头连接一串大写字母的名字(比如_VERSION)被保留用于 Lua 内部全局变量。

forloop syntax Lua has both generic for and numeric for. The generic for works similar to python's for. However because lua's table is not iterable itself, you need to callpairsoripairson the table. The following hua code: will compiled to: ...
