A clarification: Are you stating that you would like to link the
location in the index page that lists the message with the specified
bug ID?
Yes, that's it. I've tweaked the index page layout so it looks something
like this:

where the first (subject) line in each block is a link target with a name
attribute equal to the message ID of the first message in the following
list, and the subsequent (author) lines are links to the emails in the
archive related to a particular bugid. So if I build an index where I add
the (bugid, message id) pair the first time I encounter a given bugid, I can
then work out the link target I need for a given bugid. However the missing
piece of information is the name of index file that a given link is in (I'm
running with <MultiPg>). I don't see any obvious way of hooking into the
index page creation process, so my other thought was to look in the
.mhonarc.db for the <IdxSize> and friends, and work out which index page a
given link will be in that way.
see how to do that without picking apart the .mhonarc.db file. Is there any
easy way to do this that I'm missing?
Since you will be linking to something based upon the message number
assigned to an archived message, I would map the bug-id to the
message number since the message number is used as anchors in index
pages, assuming this is what you want.
Yep, that's exactly it.
Now, to do the mapping, I would do it in the $mhonarc::CBMessageBodyRead
callback since you do not have some (guaranteed) information available
when $mhonarc::CBMessageHeadRead is read (and the information I am
refering to is the message number assigned to the message).
In your $mhonarc::CBMessageBodyRead, you can get the message number
as follows:
$msg_number = mhonarc::fmt_msgnum(
$mhonarc::IndexNum{$fields_hash_ref{'x-mha-index'}});
Accessing the message number is not abstracted out very good since
you need to access the %IndexNum hash directly. If you want the
actual filename for the message, do:
$msg_file = mhonarc::get_filename_from_index(
$fields_hash_ref{'x-mha-index'});
Since the message filename is based upon the message number, you could
extract the number for $msg_file.
Yep, that all makes sense - thanks.
Now, with all that said, you may be better off using a search
engine tool, and the link you make to the archive actually invokes
a search. This way, you will actually link to all messages that
have the bug ID mentioned in it.
Yes, that's another possibility. However, as I can guarantee that all the
mail subjects will be of the form "<bugid> <synopsis>" I can easily group
them together by sorting the index by subject instead of date, with
<SubSort>, so I was just looking for some way of easily exploiting the
well-formed nature of the mails I'm dealing with ;-)
Many thanks for all your help and suggestions - I'm now off to look through
the examples and source code ;-)
