Hi,

the code editor is not so happy with my regex literal
E.g

myRegex.compile("/\d+/g") => Parser Error: Invalid escape sequence

Obviously I can't escape the \ character here.

How can I make him swallow my regex?

What do you mean "Obviously I can't escape the \ character here"? You actually need to escape, since this is no more than a regular string. Just use "/\\d+/g".

I tried it, but then the regex doesn't work. regex.find(text) then regex.get_captures() # => []. But the text definitely contains numbers and it works for me here https://regex101.com/ That's why I said obvious, because it seems to me to change the entire semantic.

For anyone who wonders, it's a really simple fix. Just remove the //g from the expression.

Instead of this

"/\\d+/g"

do this

"\\d+"

This is kind of offtopic, but is it possible to get this regex working:
http://stackoverflow.com/questions/2648716/how-to-remove-bb-codes-from-a-string

#\[[^\]]+\]#

Or do you know if Godot's RegEx system is limited to only the libraries and not the "general" RegEx? (IF that makes sense) :P

the regex for matching bbcode could be

"\\[.*?\\]"

them just use the substitution method :)
