So, I have this regex that works when I use re-search-forward interactively, but not as a function in elisp. Any ideas as to why? The regex in question is: "^#\+include:\s-*\"\([^\"]+\)\"[^\n]*$"

So, I found that backslashes must be double-quoted, but it still fails

may be this is of some help? https://emacs.stackexchange.com/questions/5568/why-do-regular-expressions-created-with-the-regex-builder-use-syntax-different-f

@sogaiu wow! I’m now realizing that regex in emacs is way more complex than I thought Thanks though. This probably explains why it fails. Just need to grasp it first 🙂

good luck! i remember struggling with this, but all i remember is that it is tricky.
