Hi all,

I'm using haskell-mode for emacs and I'm using it to open a literate haskell file which uses latex. This works fine, haskell code has syntax highlighting, and special symbols like lambda get used. However, the latex itself is dull and gree, no highlighting/coloring there. Does anyone know if it's possible to turn on latex highlighting in literate haskell mode? I tried switching to latex-mode, which does the trick (but it chokes on the haskell code inbetween), so I'm pretty sure emacs has everything it needs, but haskell-mode needs to enable this somehow.

I'm not certain this /is/ easily in Emacs capabilities.  Emacs isn't really set up to support more than one major mode at a time -- there is, however, an extension that can do this.  The challenge is defining the start and end of the areas of each 'mode' in the buffer; I've never had very much success, but depending on the delimiters used in the literal haskell syntax you're working with, you may be able to set it up:

There's a more detailed listing at configurations, etc. at: * http://www.haskell.org/haskellwiki/Literate_programming#Multi-mode_support_i... * haskell-latex.el at http://www.loveshack.ukfsn.org/emacs/ (mentioned in the MultipleModes page on the emacs wiki) But in general, I agree: multiple modes suck in Emacs. I tried all of the available attempts at multiple modes when trying to get Markdown + literate Haskell working, the best I could get was using multi-mode.el (and there are still a few glitches). In general, Emacs tends to go a bit nuts when it's time to switch modes :/ -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com

I tried mmm-mode with a few configurations, but I get into trouble when using other haskell-mode features. Also, the wiki page on haskell-mode ( http://www.haskell.org/haskellwiki/Haskell_mode_for_Emacs#Literate_Haskell ) specifically mentions mmm-mode tricks are not needed anymore and shouldn't be used.

Its built-in support does a great job to keep all code blocks working the way I want, but the latex parts are just dead text.

I wouldn't mind to switch manually, as most of the time I'm either coding (touching only small parts of latex), or writing (leaving the code parts as-is). However, latex mode seems to trip over certain code parts ($ sign in haskell code for example). So it seems it's not smart enough to just ignore code blocks.

Probably I need to look into latex mode a bit more, so it becomes off-topic for this list.

If you're using AucTeX, there's a way that you can specify that \begin{code}...\end{code} is recognised as a verbatim (i.e. "not LaTeX") environment: http://stackoverflow.com/questions/3274091/auctex-emacs-problem-with-charact... -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
