Re: gEDA-user: Restrict facility?

[Rick Collins]

You might want to take a look at FreePCB.  This is a Windows based 
PCB layout tool that interfaces to an autorouter which does support 
keepout regions for the router.  www.freepcb.com

Eagle has a facility, both in component packages and on the board,

router. I've spent some time looking, thus far without success, to 
see if there is an equivalent facility in PCB. That could be because:


 a) There is no such facility.
 b) The manual fails to mention it.

Can anyone confirm that such a facility does/does-not exist? In 
Eagle these are called restrict layers but searching the geda 
archive for "restrict" yielded only some acrimonious discussion about GPL.

This one.  We've been talking about a redesign to pcb's internals that
would allow support for this, but at the moment, we don't have it.

BTW, it can often be useful to use a tag rather than a branch when you have
a specific commit that you want someone to check out and test.

Me neither.  Strange bug!

I've built and run 2010-09-29 from the sourceforge tarball and also
recently built and run from git head.
Both have been fine on my Fedora Core 13 x86-32 system.
I also know that some community members are using Gentoo successully.
So:

* Anyone else out there running PCB on Ubuntu 10.04 ?

* Anyone else out there running PCB on AMD64 ?

If so, do you see this bug ?

OK, it is fixed.  It must have been that the VCS workspace had some
weird stale generated files because after doing fresh checkout and
rebuilding from this clean workspace, the problem is gone.

Sorry to trouble the mailing list with this trivial problem -- I thought
I had already done a really-clean build but I guess not.

Colin

Try again now.. it is possible that I didn't have the correct patches
pushed at that point. I was just pushing something out just now for
someone at Intel to test (looking at a driver bug), so we might have
collided.

PS. If you see crashes, I'm interested in the full backtrace. It might
be that the driver doesn't appreciate that I still have some buffer
mapped whilst I'm glClear'ing. (Although it should not care!).

I have installed many versions of pcb but have never seen this.
Seems like there is something peculiar about your environment 
that has triggered this bug. Can you give some more details on
your system?

* version of pcb
* Linux distribution
* Desktop environment (KDE/GTK)

You might try to start pcb in the environment of a fresh new test-account.

gEDA-user: pcb displays popup dialogs for messages instead of using log window

[Colin D Bennett]

Hi,

pcb is displaying some annoying dialogs with a "printf" style format
string instead of the usual log message window I am used to seeing.  I
can't figure out how to turn off these dialogs, of which several pop up
at startup and then whenever a message would be logged.

See the screen capture collage of these dialogs at
.

At startup, several dialog boxes are displayed in sequence with the
following contents, as well as missing/garbage characters on the two
dialog buttons (the left button--perhaps Cancel--has some sort of
missing-character glyph that shows "0008"):

#1
  Note: home directory is "%s"
#2
  Loading menus from %s
#3
  The gtk gui current ignores "%s"as part of a menuitem resource. Feel
  free to provide patches

Other things, that produce log messages, such as optimizing nets
with the 'o' key shortcut produces the same sort of thing, but worse

I've been using the pcb 2010-09-29 release (built from git sources on
Ubuntu 10.04 amd64) and also now tried the latest git HEAD as of
2010-11-07 and the problem remains.

I tried moving my ./pcb/preferences away and it didn't fix it.  Thanks
in advance for the help!  The startup messages are a little annoying,
but when I hit 'o' and get a barrage of dozens of "shorted net"
warnings, etc., it's basically unusable.

Regards,
Colin

gEDA-user: Using the Scheme API: an example!

[Peter TB Brett]

Hi folks,

Here's a nice example of what can be done with the Scheme API even in its
incomplete state.  The attached plugin for gschem improves on gschem's
built-in code for selecting a whole net (double-clicking on a net) by
recognising and following "netname=" attributes. [1]

To run it, check out and install my `guile-scheme-api' branch by following
the instructions in my original e-mail:

http://thread.gmane.org/gmane.comp.cad.geda.user/33328

If you've already done this, you'll need to update it with `git pull' and
recompile/reinstall it.

Download the attached files (`select-whole-net.scm' and
`select-whole-net.sch') and create a gschemrc file with the following
contents:

;; Load select-whole-net plugin
(load "select-whole-net.scm")

Open `select-whole-net.sch' in gschem, and select a single net segment.
Then use the Scheme prompt to run:

(select-whole-selected-net)

I hope this interesting & useful example will inspire you all to using this
stuff to do cool things. ;-)

Peter

[1] Extending this plugin to recognise and handle net= attributes on
symbols is left as an exercise to the reader.
