From Greg waters, a suggestion related to the same topic:

Hi Alex,
I add the “var” keyword in front of user types in a declaration statement or ANSI port item, to give the parser more clues that a user typedef name precedes the port or variable name. I mention that in case you can build on it to improve indentation for types.

More generally, how about adding a special comment marker? If a line within a declaration or port “region” would be auto-indented, but it has an end-of-line comment with the special mark, can the autoindenter leave that line alone and just auto-indent the other lines (which don’t have a user typedef in them)?
This give the user a way to auto-indent declarations and ANSI ports that have built-in type names, while not affecting the ones that Verilog-mode can’t comprehend.

Suppose the “keep-indent” marker is “//.”. We could improve user-type indentation this way (I use dot-space here to suppress auto-replace in e-mail composer):

module foo
.(input logic. . . . . . . . . . .clk,
..input my_pkg::user_type. . . . .keep_type_way_left, //.  <==Keep-indent marker
..output logic . . . . . . . . . .done);

import my_pkg::*;
logic [7:0]. . . . . . . . .city_bus;
var user_type. . . . . . . .keep_type_also_way_left; //.  <==Keep-indent marker

endmodule

With the help of this marker, Verilog-mode can continue to re-indent the unmarked lines nicely. The marked lines would have manual indentation.

Thanks --Greg

@monte

See if the below advice statements work for you (Works on GNU emacs 24.4+).

(defun my/verilog-selective-indent (&rest args)
  (interactive)
  (save-excursion
     (beginning-of-line)
     (let ((match (looking-at "^.*//\\."))) 
       match)))
;; Advise the indentation behavior of `indent-region' done using `C-M-\'
(advice-add 'verilog-indent-line-relative :before-until #'my/verilog-selective-indent)
;; Advise the indentation done by hitting `TAB'
(advice-add 'verilog-indent-line          :before-until #'my/verilog-selective-indent)

I "have something similar":https://github.com/kaushalmodi/.emacs.d/blob/b80883ca52fc4f6f474f94fd5c41cfc0fcd7ead8/setup-files/setup-verilog.el#L344-L363 to skip auto-indentation on certain lines.

@wilson:
Can we add a @defcustom@ regexp var (@nil@ by default)? If that var is non-nil, lines matching that regexp are not auto-indented.

Hi there. Thanks for the suggestion. Alas, it didn't work for me. Perhaps that is because I'm using an old version of emacs (v23.1.1). The message I get is:

Symbol's function definition is void: advice-add

I'm not adverse to getting an updated version of emacs, but would like to know if that's the problem before I start down that path (it would be non trivial where I work).

@advice-add@ will work only in emacs 24.4 and newer versions (the newest released version as of now is 24.5).

I have not used the older advice system. Maybe someone well-versed in that can show you how to advise those functions using the old style.

On a side note, getting the latest emacs version would really help as it comes with many bug fixes and new features.
You can build emacs locally in your $HOME directory at work without needing any admin/su rights.

Still present, perhaps someone would like to contribute a patch?
