Hi, I'm new to Sup. (I can code Ruby, a bit, but I'm finding the source hard to read, so configuration is going slower than I would like. It's me, not you...)
Can someone give me some hints on debugging hooks? For example, is there an easy way to get just one message object in the console, so I can play with it?
Is it true that the before-add-message hook can die silently if my code is bad? Will wrapping my code in begin ... rescue ... end guarantee that this doesn't happen?
Ta.

Yep, there is:
$ irb1.9.1 -Ilib
>> require 'sup'
>> include Redwood
>> start
>> i = Index.init
>> i.load
If you have some message ID you want to load, you can do so. If you don’t know
which one to load, you could print them all (beware, on a big index, this of
course will be a very long listing):
>> i.each_id { |i| puts i }
To actually load the message:
>> m = i.build_message("201010062050.45778.kern@sibbald.com")
You can then play with the masseg as you like.

Not sure about that. At least in the system log (press ; to open the buffer
manager) it will leave a trace about hooks dying, but I don’t know if it’s
display very obviously when you’re not having an eye on the log.
Best regards,
Michael

For hooks, I tried using debug. So in the before-add-message hook you
could have:
debug ("message subject is #{message.subj} and is from #{message.from.email}")
Then launch sup with debug on:
$ SUP_LOG_LEVEL=debug sup
And you will get extra logging, including your hook debug message, in
the log buffer (press ; to see the buffer list).
One thing to watch out for in the message hooks is that the regex is
case sensitive by default. To change that, just put an i at the end,
eg
if message.subj =~ /\[sup-talk\]/i
message.add_label "sup"
end
Good luck
Hamish

Thanks for all those suggestions.
I hadn't even known how to get to sup from irb! And I don't think debug is documented -- or is it?
Lot of stuff for me to try here. Expect more dumb questions a bit later...
