gEDA-user: Expansion of the footprint definition

2011-05-19 Thread Geoff Swan
   I am sure there has been discussion around this in the past - but I am
   keen to know if there is any chance of PCBs understanding of what a
   footprint can contain being expanded in the near future?

   Primarily just two things I would really like... text and polygons...

   Is this something that requires a major refactor - or is it something
   that someone who is new to the pcb source may have a chance of looking
   at?



   cheers,



   Geoff

It's been discussed, but would be a major change.  Very desirable,
though.

What is the blocking aspect? 
Is the change so intrusive that half of the code base is affected?
Or is it the problem of breaking backward compatibility? 
Or something completely different?

Both of these.  We'd need a file format change, editing code, display
code, DRC changes, autorouter changes, optimizer changes, connectivity
checks, buffer conversions, etc.

It is generally agreed that, if we're going to do that much work
anyway, it would be better to redesign the internals to have a concept
of sub-layout and have elements just be a special case of those.
