Guys --
I recently came across some symbols with strange pin syntax which made
gattrib segfault. I have fixed gattrib to be robust against this
syntax, but I am now wondering if the syntax is valid or not.
Pins can have attribs attached to them. Here is an example pin with
attribs:
P 300 4200 0 4200 1 0 1
{
T 136 4250 5 8 1 1 0 0 1
pinnumber=1
T 136 4250 5 8 0 0 0 0 1
pinseq=1
}
On certain symbols I have found pins with simple text also attached.
For example, here is a snippet of analog/CS5396-1.sym:
P 300 4200 0 4200 1 0 1
{
T 136 4250 5 8 1 1 0 0 1
pinnumber=1
T 136 4250 5 8 0 0 0 0 1
pinseq=1
T 375 4150 3 8 1 0 0 0 1
Vref
}
It has text "Vref" attached to the pin. Is this valid?
Many other symbols have this construct also.
More generally, is this syntax a good idea? That is, doing this means
that pins can be complexes, or at least have "primitive objects"
besides attributes. Does this serve a purpose? I was under the
impression that "primitive objects" only made sense for complexes
(components).
If it were me, I would say that pins may only have valid attribs
attached, and nothing else. But I might be wrong. Is there ever a
time that pins would need to have anything more than attributes
attached?
