In order to keep before-add-message.rb readable, I was using one-line
filters like:
message.add_label "ad apple" if message.from.email =~ /@insideapple.apple.com/
message.add_label "ad amazon" if message.from.email =~ /promotion.*@amazon.com/
message.add_label "list sup" if message.subj =~ /\[sup-talk\]/
message.add_label "list sup-devel" if message.subj =~ /\[sup-devel\]/
That seemed to work, somehow. Only now I realized that message.add_label
in fact only takes a single label as argument.
Is it true that I have to change the above syntax into the much more
verbose:
if message.subj =~ /\[sup-devel\]/
message.add_label :list
message.add_label :"sup-devel"
end
Removing a message from the inbox ("message.remove_label :inbox") while
applying a label leads to a similar 'code bloat'.
Also, it took me a while to realize that errors in before-add-message.rb
won't lead to a visible error message, but that before-add-message.rb
just silently quits.
The examples in http://sup.rubyforge.org/wiki/wiki.pl?Hooks are a very
good start.
Still, perhaps somebody with robust Ruby skills could add in a section
about the exact usage of message.add_label and message.remove_label,
e.g.:
- What's the difference between "label" and :label?
- Can I use multiple labels in one invocation?
- How about dashes in labels? Is :sup-devel valid, or should I use
:"sup-devel"?
- How about spaces in label?
- How about "-inbox"? Does it work?
Regards,
Gregor Hoffleit

You could try this:
[:list, :sup-devel].each { |l| message.add_label l } if condition
[:inbox, :unread].each { |l| message.remove_label l } if condition
Or something like this:
case [message.from, message.subj].flatten.to_s
when /foo/ then
[:label1, :label2].each { |l| message.add_label l }
[:inbox, :unread].each { |l| message.remove_label l }
when /bar/ then
[:label3, :label4].each { |l| message.add_label l }
[:inbox, :unread].each { |l| message.remove_label l }
end

Ok. I ended up with
([:list,:"sup-devel"].each {|l| message.add_label l}; message.remove_label :inbox) if message.subj =~ /\[sup-devel\]/
May I request a new function "message.edit_labels" that groks the syntax
of the 'edit labels' command (cf. multi_edit_labels in thread-index-mode.rb):
message.edit_labels "list sup-devel -inbox" if message.subj =~ /\[sup-devel\]/
Comments?

Nothing. Strings get turned into symbols automagically and so both will
add the label :label.
> - Can I use multiple labels in one invocation?
No.

> :"sup-devel"?
The latter is necessary, but only because of Ruby's syntax. You can also
use "sup-devel", of course.
> - How about spaces in label?
Same as with -'s.
> - How about "-inbox"? Does it work?
It will work but will give you weird errors later on down the road as
punishment for being tricky. :)
