[Caml-list] Tuareg-mode and pipes |

[Romain Bardou]

Hi list,

About two years ago, the following bug was reported:
https://forge.ocamlcore.org/tracker/index.php?func=detail&aid=659&group_id=43&atid=255

If you don't want to click, here is the issue. Tuareg indents 
pattern-matching like this:

match x with
   | Bla ->
     hello

But the previous behavior of Tuareg, which I prefer, was:

match x with
   | Bla ->
       hello

I have occasionally been updating my tuareg-mode, looking forward for 
this "tuareg-pipe-indent" variable (see the comments in the bug report), 
while patiently re-indenting pattern-matching by hand. But this 
variable, or any similar variable, never appeared.

After two years, I'm becoming suspicious that something went wrong. Does 
anybody know what happened to the patch? Or how I can get my preferred 
behavior back?

A related question is the following. I read here a few weeks ago a claim 
that the caml-mode was much better than the tuareg-mode. I was not able 
to find a comparison between these two modes, to support this claim, nor 
whether the caml-mode would fix the pipe behavior for me. Any comment 
here would be appreciated.

Cheers,

I switched to caml-mode from tuareg for exactly this reason.  I can
confirm that with its default settings, it indents in the second
style.

Thanks for your input. Do you miss anything from tuareg-mode or is your 
life just better now?

I basically use only the auto-indenting features, and they've been
fine.  I only rarely run an OCaml subprocess, for example, so there
may be differences there that I haven't noticed.

It's true.
I previously used tuareg-mode, switched to caml-mode then

Hi

Alternatively you could use typerex from ocamlpro 
(http://www.typerex.org/), which indents the way you want. As for the 
features, it does at least what tuareg does (and a few additionnal 
things which i did not tested).

Thanks for fixing this issue. Do you plan to make a new release
of tuareg?

I have C-; for a custom function called comment-current-line. It's
probably one of my most used custom functions.

I do use M-; to insert comments at the end of nonblank lines, albeit
rarely, so I would probably stick with my curernt solution.

I can be very patient, it seems ;)

Thanks for the fix! Warning: I may come back in two years if this
doesn't work.
