gEDA-dev: Proof of concept PCB Library picker (PCB Patch)
Hi all,
Please find attached a proof of concept patch for the GTK Hid which
demonstrates a PCB which supports the "--library" option.
When invoked with this option, the main GUI window is not shown, and all
logging is dumped to stdout, rather than a the log window (which remains
unshown).
When called with --library, selecting a component in the library results
in its footprint string being emitted on stderr for the invoking program
to read.
(Yes, I relise it might be nicer to have errors on stderr, and this
other output and stdout, but it would be much more work to go through
and audit any possible printf in PCB.)
Previews will have to wait for another time, however it ought not to be
too hard with the pinout windows already available.
Next job is a generic scheme interface for attribute helpers in gschem,
and an example hook which makes use of "pcb --library"
Regards,
--
