Rather than concentrating on what we don't like, I wonder if anyone can
point to a FOSS Eda tool out there that you do like. What did they do right
and what languages did they use?


What I would like to do is to step back and look at the big picture as to
where and how we can use a schematic capture tool in todays world. Things
have changed a lot since the 1980's and some things that we did back then
no longer work. One example is search paths. If you look in the default
symbol library setup then you will see that some libraries are commented
out due to name collisions. What happens when you get a new library that
collides with an existing one and commenting out is not an option?
We need to come up with a solution before our users run into that problem.

gEDA currently defines a dot_sch schematic file and a dot_sym symbol file
as our interchange formats. These are read into gschem and stored in some
internal data structure that gschem manipulates before it is written out
in  a save operation. Why not use a FOSS data base instead of internal
memory?  If PCB also used the same database then cross probing and back
annotation become easier.

Brain storming anyone?
