AUCTeX parsing question

Question

I have a problem with AUCTeX loading the correct hooks with a Beamer file.

If my file contains line breaks in the documentclass line, the style hooks are not loaded. (Thus I have no frames in my AUCTeX environments, and other commands are also unavailable.) For instance:

\documentclass[14pt,
  handout, % no transitions
  xcolor=svgnames]
  {beamer}

But if there are indeed no breaks, the style hooks are correctly loaded. For instance:

\documentclass[handout,xcolor=svgnames]{beamer}

Note that both ways are correct in LaTeX, but the first one enhances readability.

Is there a way to fix this?

Answer 1

The regexp matching \documentclass commands is contained in LaTeX-auto-minimal-regexp-list. It does accept breaks withing optional arguments, but it expects the closing square bracket be followed by the opening curly bracket. You can either write

\documentclass[14pt,
  handout, % no transitions
  xcolor=svgnames
  ]{beamer}

in your document or change the regexp in order to accept a newline after the closing square bracket. I think the former is easier to do.
