Re: [Gtkwave-users] Requests: signal name for bound process script, export SVG,

[Sujay P. <ele...@gm...>]

Hey Tony,
   Thanks for the reply. But I don't understand the responses 1 and 3:

1. Yes, a new process will be spawned for every signal. However, the logic
of the executable will still remain the same. I want to do something like:

if 'sig_name' == 'signal0':
     sys.stdout.write('None\n')
else:
     sys.stdout.write(readline)

Unless we pass the metadata for the signal, I don't see how a separate
process will help. Either passing in the signal name/id as metadata on
stdin, alongwith the signal values, or calling the process with an argument
in the TCL script would work.
Is there a way to accomplish this?

3. I know about those rc variables. However, those are static aren't they?
I want to be able to change the waveform text foreground color dynamically
(per wave phase), just as we do with the background color (using the ?...?
prefix before the value in the translation file).
Is there a way to do this?
