It's about why we end up in situations where we even feel a debugger is

I used to use debuggers much more than I do currently, (probably in
large part because I used to do more C coding), but even though I do
99% of my debugging without a debugger, that remaining 1% would be far
more painful without the debugger.
There are 2 main places where I find a debugger helpful. One is when
I make stupid mistakes (and if you don't occasionally make stupid
mistakes then I doubt you're actually programming) and the debugger
can smack me upside the head and point out the stupidity ("Oh, it's a
fencepost error!"). The other, more important case is when I am
digging into code that I am not familiar with. In those cases, the
debugger can give a new perspective and let you realize what is going
on in the code, at which point you can ditch the debugger and go back
to the code with a better understanding. Once you are familiar with
the code then the debugger becomes much less useful, but in those
initial stages it greatly speeds the progress.
Linus's rant really rubbed me the wrong way. I thought "considered
harmful" essays went out of vogue a few decades ago. If you'd rather
not use a particular tool fine, but don't imply that people who choose
to use it are somehow inferior.
I thought there was code in AOLserver to support the TclPro debugger -
has that been removed?
The hooks still exist and it even still works.
Debugging AOLserver pages
* Configure AOLserver to allow debugging, and restart:
ns_section "ns/server/server1/adp"
ns_param enabledebug true
* Download and install the TclDevKit
* Start the debugger:
% tcldebugger &
* Start a new session:
File > New-Project
* Start a new remote session:
Debugging Type > Remote Debugging
* Append the following information to the page you wish to debug:
?debug=<debug>&dhost=<dhost>&dport=<dport>&dprocs=<dprocs>
* AOLserver Dubugging Query Arguments:
debug String. The files you wish to debug. (Example: *, *.adp, foo.inc)
dhost String. The host name the Tcl debugger is listening on. (Example:
127.0.0.1)
dport Integer. The port the Tcl debugger is listening on. (Example: 2576)
dprocs String. Procedures to instrument. (Example: ns*, foo_something)
* Example:
http://foo.com:8000/test.adp?debug=*&dhost=127.0.0.1&dport=2576
<http://foo.com:8000/test.adp?debug=*&dhost=127.0.0.1&dport=2576>
Hope that helps!
