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。
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...
