[Caml-list] Vim6 and O'Caml.

[Caml-list] Vim6 and O'Caml.

[Jeremy Fincher]

I've recently installed vim6, and would like to possibly return to vim after 
a
long period of time using emacs for my coding.  The main reason I switched 
to
emacs is because the indentation worked better (more naturally, requiring me 
to
press tab less often) and because I can run an ocaml toplevel as a 
subprocess in
emacs (which has kept me from troubleshooting an annoying terminal issue I'm
having.)

I've tried the new vim6 indent files, but it doesn't seem to apply the same
rules that emacs applies, which I'm both accustomed to, and which almost all 
the
source code I've seen is writte in.  Surely all the source code I've seen
written hasn't been written in emacs, so I assume there's some way to make 
vim
indent code like emacs does.  Does anyone know how to do so?

Thanks,
Jeremy

Have you tried the ocaml indent file for vim by Marcus Mottl that you
can find at the url:

   http://www.ai.univie.ac.at/~markus/vim/indent/ocaml.vim
?

Probabily this is integrated in the new vim 6.0 release but I'm not
sure.

It actually isn't capable of correctly indenting OCaml-code. The reason
is simple: you'd need a complete parser and pretty-printer to do so. This
is an awful lot of work and slows down some operations considerably.

Currently, the indent file for OCaml does an approximate job: it
only considers the current and the last line to compute a suitable
shiftwidth. This works remarkably well in the majority of cases.

You can also program Vim (though not in Lisp). Considering the richness
of builtin functions in Emacs and the still large amount of Lisp-code
required to implement automatic indentation (~ 1500 LOCS), I wouldn't
dare to do the same for Vim. Anybody want to give it a go? ;)

Markus Mottl
