Cannot find character "^" with string.find

Help and Feedback Scripting Support
#1

I need some help because this bug is driving me completely insane.

I’ve narrowed down the exact issue with my code to this line:

local cst,cen = string.find(newstr,"^")

I know through prints that newstr is : 1={LF=-f0.313,5.048,0.513:-0.825,0.343,0.45^

However, no matter what I pass as newstr, cst will always equal 1 and cen will always be 0. Does anyone know why this is?

String.find should take the string variable.

Str = “Hello world”

If Str.find(“Hello”) == true then

End

#3

That’s not the issue. I’ve already found the issue. It’s because you can’t use special characters directly in string.find.

#4

For future reference if anyone else has this issue, you can’t call string.find on the following characters:

$ % ^ * ( ) . [ ] + - ?

I’m not at a pc to check, but look into string.format then, so you can use special chars

#6

You actually can use string.find to find those characters, but you need to escape them with a % before it, so to find the ^ character in your example it would be:

local cst,cen = string.find(newstr,"%^")

^^ exactly.
Here is the api, that I was referring too.

Be sure mark a solution, and confirm that it’s not a bug.
