I found that the above has a problem with attributes, because the "lb" and
"le" terms makes two attributes 20 lines apart look like one string
constant.  Anybody no a way to get around this (short of allowing reserved
word emphasis in strings constants :-)  ?

Also, is there a way to get vgrind to generate monospaced output?  (or is
this a function of our Sun's "lpr -t" translation into Postscript.)

A couple years ago I took vgrind and rewrote it to "pgrind", which just
generates PostScript directly. I've been trying to get permission to
release it ever since (major-sigh. Let me know if you are interested and
I can use it as ammunition). I was too lazy to rewrite the regexp stuff,
which you would really need to (MHO) to always handle ticks right, so
I made a few assumptions on formatting (using an idea from Kent Mitchell)
and currently use:
 # In order to get the ticks to work, we are assuming that there will be
 # whitespace before a literal (like '"') and *not* when used for an
 # attribute (like 'Length).
 # For sb/se, assuming literals have whitespace before/after.

        :nf=Courier:\
        :bf=Courier-Bold:\
        :if=Courier-Oblique:\

This isn't perfect, but it's better.

Ada PostScript Pretty printer?

[Tony Leavitt]

Does anybody know of a publicly available piece of software that will generate
a PostScript file of pretty Ada code.  What I mean pretty Ada code is that
resevred words are in bold and comments are in italics.  I do NOT want a
reformatter and autoindenter or anything like that.

TIA,

Why not just jam the source through vgrind, then pipe it through
psprint (or some other wild script, like mine here):

	vgrind -d <vgrind_defs_file> -lada -o1- -t -w $* | thack | lpr

Oh, here's the vgrind_defs_file I use:
# Originally submitted from Fraser Wilson

Here is another commercial for Emacs:

If you use the new Ada Mode for GNU Emacs (available at
ftp://cs.nyu.edu/pub/gnat; soon to be updated), go and get the package
ps-print.el from any emacs archive
(e.g. ftp://archive.cis.ohio-state.edu/pub/gnu/emacs/elisp-archive/) 

With this package you can print your code as you see it on the screen,
say with bold keywords and italic comments.

Agreed!  ROlf deserves a pat on the back for this one!  I'm just now
trying to get my head around emacs, and the new Ada mode (plus the
new&improved, very cool Presentation Manager (OS/2) interface for the
new version of emacs makes things VERY easy!) is quite a wonderful
addition.
