Quoting the README file: This is Yaham, Yet Another HAskell Mode for GNU Emacs. It has a different focus than the Moss haskell-mode that's normally used nowadays. Yaham strives, first and foremost, to integrate well with the rest of Emacs and respect the Emacs ecosystem. This is because I still use languages different from Haskell --- python, shell, Makefiles, even C ...) and see no end to this predicament. To my knowledge, Yaham completely and correctly handles all of Haskell's unusual lexical syntax - both line and nested comments, overloading of single quote and backslash, strings including gaps. There should be no runaway string or comment highlighting or broken cursor movement across these elements. If you find a broken case, please report it to the address below including the relevant piece of Haskell. Things that are still missing but are high priority to add: * specialization for GHC (one for Hugs is included) * texinfo documentation (for now, please explore the menus and keybindings) * installation script (perhaps a makefile) Things that are very low priority (i.e. probably won't be added): * Bird style literate source handling * XEmacs compatibility kludges To use or try it, * download http://primate.net/~itz/yaham/yaham.tar.gz * unpack * read the LICENSE (yes, please do) * copy *.el files to your local Elisp directory * optionally, byte-compile * add the following to your Emacs initialization (load-library "yaham-autoloads") (add-to-list 'auto-mode-alist '("\\.hs\\'" . yaham-mode)) ;; or if you have Hugs, you can do this: ;; (add-to-list 'auto-mode-alist '("\\.hs\\'" . yaham-hugs-mode)) Send all problem reports and patches to me (Ian Zimmerman) at yaham@madbat.mine.nu P.S. If you want to hack on it, let me know and I'll consider giving you access to the Subversion repo. Peace, Ian. -- This line is completely ham.
