The string “)” isn’t allowed to be .gsub-ed, so I was wondering how to do that. I would like to replace all occurrences of the string “)” in a given string, but it keeps giving me “invalid pattern capture”.

I think you just have to escape it by putting a % in front. ) is a special character, so to use it literally, write %) instead. See the info here: http://www.lua.org/pil/20.2.html
Hope this helps.

I’m not getting the error any more, but now it’s not doing anything in a string that has “)” in it.
Any other ideas?

Can you post the code you’re using?

[lua]
local swap={
["%)"]=" "
}
local function formatStringWithSwap(str)
for k, v in pairs(swap) do
str:gsub(k, v)
end
return str
end
print(formatStringWithSwap(“ABCDE)”))
[/lua]
Ok, I think I’ve got it - this works:
[lua]
local swap={
["%)"]=" "
}
local function formatStringWithSwap(str)
for k, v in pairs(swap) do
str=str:gsub(k, v)
end
return str
end
print(formatStringWithSwap(“ABCDE)”))
[/lua]
Glad you’ve got it working. :-)
Thanks for the tip on escaping!
