gEDA: Libraries, licenses, et al.
Hi folks,
First off, I'm absolutely going to keep the results of any
conversion to myself. I'm a licensed orcad owner..and thus
have the license to use the libs.
On the other hand, there may be MANY others in my same
boat, and a conversion utility WOULD be handy to them.
Such a conversion utility would be written for gEDA and
GPL'd.
That being said - Let me put my vote in for what Stefan
suggested. about formats. I read thru the mail archive before I
ever posted just to see if my answer laid there first. By the
way - the initial answer turns out to drop back from gtk-1.0.4
to 1.0.0. (To Ales - my copy of 1.0.4 came from the GNOME
0.25 or 0.26 release directory.)
Back to library formats - The more powerful environments I've used
(and that numbers 5 or 6 at this point) are the ones that use ASCII files
or have an export/import to ASCII option available. These tools allow
themselves to be integrated into design-tool flows employing tools from
multiple vendors.
After reading thru the mail archive, and seeing Ales's most recent comment
about tending toward Scheme. I'd suggest that there might be some good in
keeping the database separate from the feature extension mechanism. One
operates on the other. This doesn't imply to me that they need to be one and
the same. If the two are merged, this almost completely negates the
possibility of an import/export feature.
Now Ales is doing most of the work..so OBVIOUSLY his decision will be the right
one by default ;-) However my filter idea gets considerably more difficult if
scheme gets in the way. As it was, I was figuring on just getting Yacc and Lex
out and throwing something easy together from the Orcad documentation...and
converting over to what I believe is the current .sym format.
EDIF was invented for JUST the reason we're talking about, i.e. Design
Interchange. Making it the result of schematic or library import/export
operations seems a good choice from my point of view. My two cents worth....
