Hi Guys!

I have a string and it contains print("Hi"). I am trying to remove everything in that statement except the actual thing it is trying to print.

I tried this

str:gsub('("', "")

but nothing worked sadly. When i do that, it returns (Hi)

Thanks!

string.gsub uses patterns AFAIK and "(" and ")" are special characters. Try this:

str:gsub("%(","")

But you could also do something like this:

local what = str:match "print%((.+)%)"

This matches (or atleast should) everything inside the parantheses.

Or try:
str:match 'print(%b())'
but note that calls can also be:
print ''
print ""
print [[]]
print {}
print ()

Your pattern doesn't work. Partially for the same reason OP's pattern won't work.

I forgot some brackets, thanks ^^.
I edited it in my preview post.
