Question

Could anyone tell me how to toggle case sensitive searching on string find?

Also whole word searching?, is this even possible?, I figured I could concat a space character to the beginning and end of the string I want to look for but this wont work if the searched word is at the start or end of the string.

Could anyone tell me how to toggle case sensitive searching on string find?

There is no case-insensitive flag/toggle in Lua’s pattern-api. See:

• http://www.lua.org/pil/20.4.html
• Case-insensitive Lua pattern-matching

Also whole word searching?, is this even possible?,

Lua’s pattern matching has no “word boundary” meta-char, like other pattern-match/regex api’s have. So the answer is: “no”.

I figured I could concat a space character to the beginning and end of the string I want to look for but this wont work if the searched word is at the start or end of the string.

It’s a bit trickier than that: think about punctuation marks.
