detect if inside a LaTeX ``quote'' and return its bounds?

Question

Q: how can I test if point is inside LaTeX ``quotes,'' and how can I get the bounds of that quote?

LaTeX quotation marks are kooky, typesetting ``text inside a double-quote'' and `text inside a single-quote' for the standard "text inside a double-quote" and 'text inside a single-quote'.

I'd like to detect if point is inside such a quote (either single or double) and, ideally, return the bounds of the quoted passage. However, syntax-ppss does not appear to recognize such passages as strings (re: elements 3 and 8 in the returned list; see parse-partial-sexp for details).

Is there a predicate function baked-in to AUCTeX to do so? Many of their functions also have curious naming conventions, so I may have missed it. If no such function already exists, what alternatives would work?

Answer 1

You need this:

(defun latex-quote-bnd ()
  (save-excursion
    (beginning-of-line)
    (when (font-latex-match-quotation
           (line-end-position))
      (cons
       (match-beginning 0)
       (match-end 0)))))

I found font-latex-match-quotation simply by following describe-face.
