Adding "package require spice" to your .magic file should work!
for more polished integration:
tclspice is basically the normal ngspice binary with all the commands
wrapped to TCL functions.
I also added some extra functions to export Tcl/BLT vectors either
though the plot interface or by name and array range (see
spice::spicetoblt command ).
The pretty graphics, the current plot command, is all done on the Tcl
side in the pkgIndex.tcl file.
Unfortunately the spice C source code uses printf quite a lot so the
output for most commands goes to the command line (not Tk console).
There is a quick fix by doing:
#undef printf
#define printf my_printf
int my_printf() {
/* Some C code which writes the output to Tcl though the Tcl puts
command */
}
in some header file. The Tcl_interp will need to be stored somewhere so
it can be used by my_printf for calling Tcl_Eval.
Also some checks will need to made so when spice is running in a thread
it doesn't use the interp otherwise a race will occur.
I hope this is what you are after,
Stefan
