Concatenation (串接) 使用操作符.., 可以将字符串连接在一起.例如, > = "hello" .. " Lua user" hello Lua user > who = "Lua user" > = "hello "..who hello Lua user 1. 2. 3. 4. 5. 数值同样可以连接字符串. 这种情况下, 数值会自动被转换为字符串, 然后进行拼接操作. > = "Green ...

luaZ_freebuffer(L, &g->buff); /* free concatenation buffer */ } 1. 2. 3. 4. 5. 6. 具体创建逻辑 1. 创建字符串对象: 字符串的内存结构是:TString+字符串内容+'\0','\0'是结尾标识,这一个结构的设计实在太棒棒了,直接省掉一个指针指向具体字符串内容,读取的时候只需要读一块连续内存。
This blog post explains the basics of string concatenation, the problems it causes and insecure string concatenation functions in C. It then examines format string vulnerabilities, how they appear in different web applications, and their relation to XSS
Using + operator for concatenation breaks lua metamethod to sum string as numbers (Example: "10" + "1" return 11 (number)) and this is 400 times SLOWER! local stringmeta = getmetatable("") function stringmeta.__add(str,x) return str..x end -- This will work function string.__add...

Returns the size in bytes of any string packed with a given description. rep(s : string,n : number):string Returns a string that is the concatenation of n copies of the string s. reverse(s : string):string Returns a string that is the string s reversed. split(s : string,separator ...
This library provides generic functions for string manipulation, such as finding and extracting substrings, and pattern matching. When indexing a string in Lua, the first character is at position 1 (not at 0, as in C). Indices are allowed to be negative
