after without tk

[Erik Selberg]

I'm trying to use the "after" command, or something similar, to do
polling in tcl. However, I'd rather not pin myself to using X windows,
and it seems that after requires me to run with tk and windows and
all the good stuff therein.

Is there a way of side-stepping this to get some sort of time-delay
script calling mechanism without dealing with X?

Thanks,
Erik

You need the event-loop mechanism in tk to implement after. Try using
Tcl-DP version 3.2 -- the "dplite" subdirectory contains source for a
wish-like interpreter decoupled from X. You get after, wait-for-variables,
idle, and send like mechanisms without needing X sources or libraries to
compile/run.
