George Peter Staplin 2007 Nov, 14 - Netcall is a remote eval package. It's optimized for speed, and has more capabilities than comm. It's used in the Whim window manager.
It's BSD/Tcl licensed (the same license as Whim).
The sources are here: http://www.xmission.com/~georgeps/implementation/software/netcall/
Eventually netcall may be part of http://code.google.com/p/megapkg/
A simple example for a server:
set dir [file dirname [info script]] source [file join $dir netcall.tcl] netcall.init netcall.serve 8888 vwait forever
The clients can do:
set dir [file dirname [info script]] source [file join $dir netcall.tcl] netcall.init netcall.connect localhost 8888 puts "SERVER PID is:[netcall pid]"
Now there's also some more power available. You can wait for variables to change on the server side.
set changedby [netcall.vwait ::someservervar ::anotherservervar]
By default netcall takes args as a parameter. If you already have a command that is a list you can use:
set result [netcall.1 $somecommand]
