[Caml-list] tuareg clause indentation in pattern matching

[José Romildo Malaquias]

Hello.

I am using tuareg-mode-2.0.6 with emacs-24.3.1 to edit OCaml source
code.

I want to have the clause in a pattern matching indented like the
following:

  | pattern ->
      clause

But I am getting:

  | pattern ->
    clause

I have tried with tuareg-match-clause-indent set to 3, but nothing
changed.

Any clues?

Romildo

I suggest you to use ocp-indent [1]. It should work with tuareg mode.  

Best,

Daniel

If you (setq tuareg-use-smie t) in your .emacs I can probably help you
get that indentation.

Indeed that does the trick but this causes all sort of other annoying
indentation rules, such as:

foooooo bar
        bla

instead of:

foooooo bar
  bla

Indeed, SMIE likes to align arguments.  As the author, I of course agree
with this decision and think it only makes a lot of sense.  If you want
less indentation then you have to use

   foooooo
     bar
     bla
