@User showing the real resistance (same for capacitances) can be done now, there is no specific code in xschem, only parameters in library cells (like 'rho' for resistors) :

Nice improvement! Thanks for your effort. Is it also possible to save the script in a file and use tcleval to run it?

@raphael you can source a tcl file (either from xschemrc or by doing

source file.tcl

at the command prompt) if this tcl file declares a procedure this procedure is available and can be used in tcleval, like:

tcleval([myproc .....])

. Putting a '`tcleval( [source file.tcl] [myscript ....] )` ' in the symbol's

tcleval()

is highly inefficient as it will load again and again the file any time the symbols are redrawn
