string.sub(s, i [, j]) strsub(s, i [, j])
Return a substring of the string passed. The substring starts at i. If the third argument j is not given, the substring will end at the end of the string. If the third argument is given, the substring ends at and includes j.
Example
> = string.sub("Hello Lua user", 7) -- from character 7 until the end
Lua user
> = string.sub("Hello Lua user", 7, 9) -- from character 7 until and including 9
Lua
> = string.sub("Hello Lua user", -8) -- 8 from the end until the end
Lua user
> = string.sub("Hello Lua user", -8, 9) -- 8 from the end until 9 from the start
Lua
> = string.sub("Hello Lua user", -8, -6) -- 8 from the end until 6 from the end
