If repl is a string, then its value is used for replacement. The character % works as an escape character: any sequence in repl of the form %n, with n between 1 and 9, stands for the value of the n-th captured
s = string.gsub("Lua is good", "good", "bad?") print(s) --> Lua is bad 1. 2. string.gsub 的第二个返回值表示进行替换操作的次数。例如, 下面代码计字符串中空格出现的次数: _, count = string.gsub("test test", " ", " ") _ 表示哑元变量 模式串 . 任意字符 %a 字母 %c 控制字...
We can specify a character in a literal string also by its numeric value through the escape sequences \ddd and \xhh, where ddd is a sequence of up to three decimal digits and hh is a sequence of exactly two hexadecimal digits. As a somewhat artificial example, the two literals "ALO\n1...

) String 表示一串字符的数组。 Lua 是 8-bit clean 的: 字符串可以包含任何 8 位字符, 包括零结束符 ('\0') (参见 §2.1)。 Lua 可以调用(和处理)用 Lua 写的函数以及用 C 写的函数(参见 §2.5.8). userdata 类型用来将任意 C 数据保存在 Lua 变量中。 这个类型相当于一块原生的内存,除了赋值和...
Starting from v0.39, ZeroBrane Studio is using LuaJIT as its internal Lua engine. LuaJIT is a bit more strict than Lua 5.1 in some checks and may return errors even when your application runs fine by Lua 5.1. One typical example is string escape sequences. Lua 5.1 listsescape sequences...
Lua 中有八种基本类型:nil,boolean,number,string,function,userdata,thread, andtable.Nil类型只有一种值nil,它的主要用途用于标表识和别的任何值的差异; 通常,当需要描述一个无意义的值时会用到它。Boolean类型只有两种值:false和true。nil和false都能导致条件为假;而另外所有的值都被当作真。Number表示实数(双...
