Description

Escapes all special characters within a string, making the string safe for inclusion in a Lua pattern.

Arguments

1 string str
The string to be sanitized

Returns

1 string
The string that has been sanitized for inclusion in Lua patterns

Example

Replaces all occurrences of "100%" in a string with "0%" and prints it.

We call string.PatternSafe here as '%' is a special character when used in Lua patterns.

local result = string.gsub( "You scored 100%!", string.PatternSafe( "100%" ), string.PatternSafe( "0%" ) ) print( result )
Output: You scored 0%!
