Re: Fileformats and library


Just a few thoughts of mine...
(note i use the term symbol for everything below regardless of what it
really is, you can figure out what i mean...)

I don't think these should be installed world writeable or anything
like that as a solution. I think it's reasonable to have people copy
and modify ones if they like, but the way to do that is probably to
allow overrides, i.e. look in users home directory and use symbols
from there instead of the stock ones if they have the same name.

Probably each symbol needs a version number (incremented for any
non-trivial change), which is stored in the kicad file when it's used.
That way if you load a kicad file that used old version of symbols
(e.g. after an update to kicad that used included new symbols) you can
be warned of the change.

Seems reasonable, e.g. home dir suggestion above.

Right, you must have been talking about something different in C above.

Yes, please put them in a zip file, or some other such archive. There
is something horribly inefficient about lots small files when one
large one will do. I agree with your logic though, having separate
files for each symbol. Using an archive seems logical to get the
advantages of both, just takes a little more effort to implement.

Nice yeah, but I wouldn't think that important unless you set up your
systems identically so you can move between them with the same path
