@dlmiles I have added a new token you can add to a symbol:

@#pin_name:spice_get_voltage

this will print the voltage value of the net attached to the symbol pin. Example:

@#D:spice_get_voltage

(get drain voltage) The motivation for adding this new attribute is efficiency. No tcl is used to retrieve the voltage, so it is very fast (and simpler expression). Also in latest xschem I got rid of all the

net_name=1

stuff so you don't need to add these attributes and enable option

View->show/hide->show net names on symbol pins

(now active by default).

Thank you Stefan this is working great.

do a

make distclean

to rebuild completely. I have added some code to detect libreadline presence on the system (although I am not using that yet). Your problems are due to some forgotten file additions to the github repo. fixed this late morning.
