Brainf* interpreter in RegEx only (find/replace)
-
I’ve written a Brainf* interpreter in RegEx. All you need to do is add the source code in Brainf* on the first line of a new document and use the following parameters in find/replace (click “replace all” until it doesn’t find any matches). Documentation here
Find:
