The XCircuit website has scattered comments about the current
development and eventual arrival of "ASG", or Automatic Schematic
Generation.  It is probably not obvious without knowing the details,
but if you can reliably generate a schematic automatically from a
netlist, then you can also rip up and regenerate parts of it on
demand.  This is what we're working on with the ASG implementation,
which also, as the name implies, should be able to generate a
schematic directly from a netlist such as a SPICE deck.

Interesting method, and probably not difficult to implement.  I would,
however, like to clean up the basic selection mechanism first.  In
particular, some of the support routines for the "undo" function I
implemented recently should allow me to get rid of the somewhat
clumsy serial accept/reject mechanism for click-to-select (as opposed
to area box selections).  I have also had people suggest the
implementation of the "strokes" library.  But it's rather time
consuming to add support for everyone's favorite interface.  But of
course, I have to be told what the interfaces are before I can
decide if they're worth implementing or not, so thanks for the
description.
