[9fans] pic

[Steve Simon]

Hi,

I would like to try to get something  running which
would allow me to draw pic documents in a WYSIWYG style
I have a load of rather complex drawings to do.

The obvious candidates (it seems to me) are:

	art (from the 2nd edition), though Andrey did stirling work
	porting it to the draw model years ago I honestly don't feel it
	up to the job - perhaps my lack of stamina?

	cip/xcip - this is part of the blit distribution and xcip is
	avaialable on the net these days. I have a vague memory that
	someone got this to run on a modern OS - plan9/X11 perhaps?
	anyone know more?

	picasso - this would be x11 only and was in the later DWB
	distributions but I seen no sign of any source for it anywhere.
	anyone have the code which I could copy?

	xfig + transfig - feels a bit like a patch on a patch and, being
	modern unix code would (no doubt) include configure hell...

	MS windows + visio, print to a file and include it as postscript
	into my troff doc - feels like gining in.

Thnaks for any help/advice.

-Steve

I use xcip on a  modern Unix;
http://plan9.bell-labs.com/sources/contrib/vsrinivas/xcip-modern.jpg

There is a tarball in my contrib, xcip.tar; it is a copy of 1995-era
xcip, made to build on recent linux systems. It needs Plan9port to
build (9's lex and yacc, iirc).

geoff had a version of xfig running on 3ed years ago. i can try to
dig it up if you want to go that route. i didn't use it much, but it did
the job when needed.

wow, my memory sucks. i'm now pretty sure that (1) this
was actually xpic, not xfig, and more importantly, (2) i
think we were running this on a solaris box in the lab and
only displaying locally to the old plan9 x11.

sorry

If you will never have to edit them, whiteboard + digital camera.

Otherwise, I've found that it is always worth the time to
program the drawings (pic macros, postscript functions,
metapost, whatever), because then editing them is possible.

out of interest, which of these do you use yourself by preference?
for example for this diagram:

http://2.bp.blogspot.com/_ZnVhQ3NyEx0/S4NfiL9UgZI/AAAAAAAAAB0/mW2hZr-Ay5k/s400/gorace4.png

getting those curves right can't be that easy if you're working
out the parameters manually, and doing the collision avoidance
programmatically can't be too easy either...

I don't think I have one that I would say I prefer,
but they're all preferable to using a WYSIWYG editor
and then having to go back and change all the diagrams
in the same way.

This was pic, with copy-and-paste but only around 60 lines.
It's a one-off.

Steve said a load of complex diagrams, though, and for that
I think it's more important to be able to go back and
fix things.  The diagrams in the regexp articles are also
pic but with macros for drawing each kind of node.

MetaPost.

I found finally easier to program than to try to get exactly what I want
with a graphical interface.

To see it with kerTeX :

tex mproof <fig>.[1-9]*

and then dvips to have a "book" with all the figures. (mproof is part of
John Hobby's MetaPost.)

Is pic out of sync with its man page?  Also there doesn't seem to be any
target for tpic.

Probably.

Tpic builds in /sys/src/cmd/tex/tpic.
I forgot the binary when I built the tex
distribution.

Thanks; Russ also hinted at that.

I was mostly fighting myself.  It's been a while since I pic'ed. I did
have a couple of suicides with tpic on some bad input. I didn't investigate,
but I can try to investigate it when I have some time.

The man page for pic includes two identical examples; I'm not smart
enough to know if that is on purpose ☺

FYI, I was building a pic that shows the steady-state process/data flow
in srvold9p.  I've attached in case somebody is interested.

i think that's because the second example is .PS/.PE input for pic
but it doesn't work well in troff -N (nroff).  try
	man -t 1 pic  |  page -w
to get something closer to the intended effect.
