Ohhh what tangled webs we weave. If you do this Stuart please document
it extensively so that others reading the code will understand why you
are doing something so convoluted.
Thanks,

Hi Peter --
Hi Stuart,
when you ask for my opinion, here it is:
gnetlist -I -g spice-sdb foo.sch
The -I flag tells gnetlist to not put the contents of any file into
the netlist, but rather just put a ".include foo.bar" directive in the
deck. (Note that I don't think I have tested this on .include
directives, so if it does the wrong thing, please let me know.
Revert this behaviour. By default, write only the .include line and when
using:
gnetlist -I -g spice-sdb foo.sch
Include the model to the spice input file.
I could do this, but there is a snag: The -I flag is really meant to
control the behavior of .model and .subckt cards. By default the
contents of a .model or .subckt file gets dumped into the main SPICE
deck *unless* you specify the -I flag. As a correlary, it will also
control the behavior of the ".include" symbol.
Therefore, I don't want to invert the logic of the -I flag without
more thought since it impacts the behavior of things beyond the
.include symbol.
The problem is that ".include" is both a SPICE statement (command),
and a gschem symbol. It is one of the only SPICE commands which also
has a gschem symbol; most other SPICE commands are entered exclusively
by manually sticking them into a SPICE-directive symbol. Since users
see the .include symbol in the SPICE symbols lib, they assume that it
generates a .include statement, but it instead embedds the named file.
I probably exascerbated this by labeling the symbol ".include", when I
really meant "embedd external file".
Moving forward, here is another suggestion:
3. Borrowing a riff from you, Peter, I could make the default behavior
of the .include symbol to just write out the string ".include
foo.bar". Then I can add a gnetlist flag, say -e, which will force
all .include symbols to embedd the external file into
the SPICE deck.
This creates the desired effect (i.e. stick a ".include foo.bar" into
the netlist by default) while not messing around with spice-sdb's
behavior with .model and .subckt cards. What do you think?
Stuart
