Subject: [geda-user] automatically create a .sch file containing a single component?
To: geda-user AT delorie DOT com

Another small thing I'd like to automate is my setup for validating
footprints of symbols.  I use heavy symbols with footprints associated
with each part.  To check a symbol I first create a .sym and .fpt,
then create a file checkfpt.sch which contains just the .sym, then use
gsh2pcb to create a pcb file containing the symbol, and launch pcb to
take a look at it.

The part that's pointlessly interactive is the creation of the .sch
file.  I have to have gschem launched and manually add the symbol.

I'd like to do one of these instead:

* create an sch containing just the sch using some batch mode op

* just create the sch by script.  but I don't get why some text
elements (refdes=, device=) end up
  repeated in the .sch file and other stay in the element.  what
distinguishes these elements?

* create the pcb file directly.  sort of a hassle but probably what
I'll do unless there's a better way,
  a little weird in my case since I have a lot of footprints using a
text library of my own

* view the footprint file in a way that shows the refdes.  I know it
possible to view footprints directly
  with pcb, the only problem with this is it doesn't show the refdes.
Is there some way to make it
  do so?
