Subject: [geda-help] Double file inclusion with spice-sdb backend
To: geda-help AT delorie DOT com

Hello,
including a file that contains a .model directive using a
spice-include symbol in gschem and then exporting the netlist using
gnetlist's spice-sdb backend results in a netlist where the included
file is present twice.

Is this an intended behavior or a bug? If the former, what's the
rationale for that?

Here's a SSCCE to reproduce the issue, include-test.sch:

    v 20130925 2
    C 45200 52200 1 0 0 spice-directive-1.sym
    {
    T 45300 52500 5 10 0 1 0 0 1
    device=directive
    T 45300 52600 5 10 1 1 0 0 1
    refdes=A1
    T 45300 52300 5 10 1 0 0 0 1
    file=include-test.sim
    }

and include-test.sim:

   V1 0 1 5
   .model MOSN NMOS

Save the schematic and then run

    gnetlist -g spice-sdb -o include-test.cir include-test.sch


The resulting include-test.cir file, removing some comment line, is:

    * gnetlist -v -g spice-sdb -o include-test.cir include-test.sch
    *vvvvvvvv  Included SPICE model from include-test.sim vvvvvvvv
    V1 0 1 5
    .model MOSP PMOS
    *^^^^^^^^  End of included SPICE model from include-test.sim ^^^^^^^^
    *
    *==============  Begin SPICE netlist of main design ============
    *vvvvvvvv  Included SPICE model from include-test.sim vvvvvvvv
    V1 0 1 5
    .model MOSP PMOS
    *^^^^^^^^  End of included SPICE model from include-test.sim ^^^^^^^^
    *
    .end

see how the file is present twice.

Commenting out the .model directive in the simulation file, thus
leaving only the voltage source element, yields the expected output,
with the included file present only once.

I'm using geda package 1.8.2 on Debian 8.
