[Caml-list] Tuareg mode: Indentation of application arguments

[Romain Bardou <romain.bardou@inria.fr>]

Hello Caml-list,

I have finally took the time to configure tuareg to correctly indent 
after a "| ... ->" clause. After several years of doing it by hand, this 
feels soooo much better :) To do this I had to add "(setq 
tuareg-use-smie t)" to my .emacs (which I found a little confusing, by 
the way).

However, now it's indentation of application arguments which is messed 
up (to my tastes). Let's say I am writing:

a_very_long_function_name argument_1 argument_2 argument_3 argument_4

Now I want to put argument_4 on a new line. Before, I would obtain:

a_very_long_function_name argument_1 argument_2 argument_3
   argument_4

which I liked. Now, I obtain:

a_very_long_function_name argument_1 argument_2 argument_3
                           argument_4

Note that if I put all arguments on their own lines, indentation does 
not depend on the function name:

a_very_long_function_name
   argument_1
   argument_2
   argument_3
   argument_4

I did not find any variable controlling this behavior in the tuareg 
group. Do you know how I can obtain my beloved behavior back? Or is it a 
bug, in which case I should submit a bug report?

The reason I don't like this behavior is that it causes several issues:
- changing one function name would imply that one would have to reindent 
everything (non-local indentation: bad!);
- the indentation is not simply "indentation of previous line + N" where 
N is the same everywhere (complex indentation rule: bad!);
- the indentation size may be very long (sudden-death indentation: bad!).

My version of tuareg is 2.0.6.

Cheers,
