unfortunately it appears that unless i've missed something (usually
the case!), it's still relying on xor drawing, so nothing gets erased
properly.

on a completely different note, i've just modified a version of
history(1) to give it a -f option to force it to continue searching
back in time even if the file in question doesn't exist for some
dates.

e.g.  history -f blah.c will tell you if blah.c ever existed in the
current directory.

if anyone's interested, i'll send the source (i don't know of a
general "contributions" address that's not this list; is there one?)

  cheers,
    rog.

Yes, you are right.
If we want to improve it, I think we'd use memdraw functions which
we applied for our new one, marsv.   However, you will have to work
much for it.   I'd be happy, if someone can contribute to art.

I'm going to show my age here, but what are
the standard set of programs used to generate,
say, pic format images for insertion into
papers?  I'm trying to create some figures
for a document and I'm not quite certain
where to look.

xfig (linux and others) generates pic, if you don't want
to write pic yourself.

So the figures in, say, the il paper were written by hand?

I don't mind learning pic if it was designed to be human
writable.  I just need to be told that.

I wrote pic by hand a few months ago for the very first time.
It's not hard to learn.

was a great help.

pic isn't that hard to learn, but it may become difficult to
maintain the pic description as the complexity of the
diagram increases.

Re: [9fans] pic generators?

[Charles Forsyth]

each time i set out to use cip/art/xpic/... i end up
deciding that it was all a big mistake,
life's too short, write the pic myself
(or generate it from another notation) in a fraction
of the time i've already spent,
and get on with what remains of my life.

Re: [9fans] pic generators?

[Russ Cox]

all the diagrams in /sys/doc/fossil.ps were
drawn with pic, by hand.  the [ ] block construction
is your friend.

if you're drawing things with a regular structure,
you often get better results with pic by hand than with
something like art.  you can make sure the regular
structure is expressed exactly.

on the other hand, if you're trying to draw figure 1
or the il network state diagram, art might be more
helpful.

art is in /n/sources/contrib/art.

It depends upon how complicated the diagram is.
Asking the local guru for sample macros is always
a good idea.  In my experience, xfig produces
inferior diagrams; others may be more adept with
it, though.

Pic's language is pretty easy to learn.  If you have
access to cip or xcip they were the original GUIs for
laying out pic images.  There are reports that xfig
can output in cip format.  Many preprocessors output
pic files (e.g. grap, dag, chem).  Grap is fairly
general, while dag (later dotty et al.) lays out
graph structures and chem formats molecular diagrams.
These can exploit pic's programmability, which isn't
quite as powerful as PostScript but is much easier to
use.

Re: [9fans] pic generators?

[David Butler]

In the second "release" there is a program called "art" that creates "pic"
output.

(One of these days I'll get enough time to catch up with fourth release.
Each
time I try to put it under load it crashes and I haven't had time to merge
my
second "release" changes into it.)

Rich Stevens used raw pic for all his books.  He posted some interesting
examples of how he used it at <http://www.kohala.com/start/troff/troff.html>
along with the pic macros that he used.

In addition to the excellent groff pic manual that Eric Raymond wrote,
you might also want to look at the chapter on pic in _Unix Text Processing_.
You can find (the recreated) UTP at <http://www.alltel.net/~kollar/utp/>.

Since we're at it, there's also www.troff.org, which has a pointer to the
recreated Unix Text Processing.  The scanned bitmaps of the original are
available from O'Reilly.

That UTP is back from the dead is a wonderful development, at least for
dinosaurs like me.

Pic is a powerful language, but it is easy to learn and use.  As
others have mentioned, it is always easier to do pic by hand.  These
guidelines help me:

* know what it is you want to draw.  Do it by hand first
so you have a pretty good idea how you want to lay it out.
* if there is a natural flow order, use it.
* define things in []; Label the objects (e.g. A: box).
* use relative coordinates (e.g.  .n, .e, .w, .s) and lengths (e.g.
1/2 of the way between) in reference to labeled objects;
it helps when you move things around.

There are lots of examples.   Richard Stevens did a tutorial paper that
you can find with google. Also I think the macros from one of his
books (I think UNIX Network Programming) could be found.
