Given a document written with normal quotes, e.g.
Ben said "buttons, dear sir".
I replied "Did you say 'buttons'?" to him.
What ways can one turn these sort of things into LaTeX quotes, with the appropriate semantics. i.e.
Ben said ``buttons, dear sir''.
I replied ``Did you say `buttons'?'' to him.
So that LaTeX produces:
Ben said “buttons, dear sir”.
I replied “Did you say ‘buttons’?”
My first thought is to turn to a regex. However, I'm not getting any hits from Google or the regex libraries for "LaTeX quotes regular expression", and of course "TeX quotes regular expression" seems to return too many.
Thank you.
Do not use regular expressions for this kind of task!
Maybe you can get some inspiration from SmartyPants?
