Custom indentation in Emacs Vhdl-mode

Custom indentation in Emacs Vhdl-mode

[haws]

Hello!
I hope some emacs guru can give me a tip on this :)
My organization requires that the following indentation is used in this
particular section of the code:

library ieee;
    use ieee.std_logic_1164.all;
    use ieee.std_logic_unsigned.all;
    use ieee.std_logic_arith.all;

Can I customize vhdl-mode to beautify like that to me?
The problem is that those 4 lines all return the same value in
"Syntactic Info" ( = statement), so I have no clue if what I want is
possible.

Any ideas?

Thanks,
Hugo

Since I hijacked your thread, here's an idea.

Yes. If you look at the source for vhdl-beautify-buffer you will
see that it is pretty tightly wound. I would write a
wrapper function called vhdl-align-use that would
call beautify then find the first USE, insert three spaces, etc.
Something like:

(defun align-use () "Indent vhdl use clauses"
  (vhdl-beautify-buffer)
  (beginning-of-buffer)
;;code to search for "use" lines and insert three spaces goes here.
)

Ok, thanks! I guess that solution will do!

I thought I'd have to change the syntactic meaning of "use", but
vhdl-mode is kinda complicated (20k lines), so I probably don't want to
mess there anyway :)

Thanks to HS and Martin for the vhdl-mode tips.
Looks like emacs wins round one 3 to nil :)
