Heck, I don't even > know what SW pros mean by "fork" :-) Sorry, its easy to get caught up in jargon. http://en.wikipedia.org/wiki/Fork_(software_development) Where software development paths have diverged. This often happens in gEDA when people start working on new features. We start to call it a fork when the amount of changes becomes non-trivial, and when they aren't necessarily compatible with the main-line codebase. Sometimes they get merged back ;), but often that requires a large effort on the part of the developers involved.

PCB supports similar naming in the netlist (it ignores lower-case letter suffixes), but some of the tools (gsch2pcb / gnetlist) would currently be confused by that. I did have a patch which made gnetlist ignore such suffixes, but it broke a few corner cases (hierarchical schematics use the refdes on IO pins as a key, and there was never any rules saying lower-case suffixes would be ignored.) Mostly for that reason (IIRC), it was generally agreed that the patch should be reverted, and people using slots ought to use refdes=U? type naming. Nothing stops adding a "label=U?A" attribute, but perhaps something more automated could be thought up. You're encountering some of the down sides to gEDA's great flexibility. Since there are so many possible conventions, ways this "could" work, work-flows (which all might have special rules for refdes), hard-coding automatic behaviours becomes a difficult decision to take. I did produce a scheme hook script (like a plugin) once which resets component names back to U? or whatever when you copy-paste blocks. It might be possible to produce a similar plugin for auto-numbering things. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!) _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
