One thing I really miss in the Aolserver/Tcl world is a good debugger

has a lot, but nothing compared to the Perl/PHP world.
The Tcl Dev Kit Debugger should be able to be inserted into the
AOLServer
environment for effective debugging. You currently couldn't do
that with
Komodo, but if there was demand, we could make some modifications.
However,
TDK can handle multiple simultaneous debugging sessions, so it
should really
be adept at the debugging needs of something like AOLServer.
Jeff, I agree, BUT feel free to express my vote for a Mac OSX version
of Tcl Dev Kit. <grin>
Komodo is on OSX, but as you indicated, the Komodo Tcl debugger won't
work with aolserver (I worked with your activestate tech support
folks and they said it wasn't supported)
As to "why a debugger for aolserver"?
Any large web-based application shares many of the same complexity
problems of traditional applications, and from my C++ days, I learned
that I should never leave code in that I hadn't stepped through at
least once.
Lots of the bugs on BookMooch (22,000 lines of Tcl procs at launch)
have been logic errors, and in the beta and first month of launching
BookMooch, my bug database reports 414 separate bugs fixed. That's a
lot of code, and a proper debugger is nice.
One nice thing tclhttpd has is a debug mode that gives you a stack
track, and a few other introspection features when a Tcl error
occurs. Might be worth borrowing the concept.
If it weren't for Komodo doing syntax checks as I type my Tcl code,
I'm sure I'd have many more bugs (that's an amazing feature, folks,
if you don't know about it)
