headers and being stumped.

headers and being stumped.

[Wes Hardaker]

Ok, so lets say I want to do something special with generic headers
and the summary buffer.  I thought I'd start with something simple,
like the user formatting and insert something boring then.  From what
I gather:

1) I can't find a way given a header structure to return a generic
   header (say x-my-gnus-is-cool:).  You only have access to the
   contents of the header structure.
2) There should be a way to get a generic header given the message id,
   but its hard to wade through all the gnus functions looking for it.
3) its likely that if #2 is possible, it'll be slow.  yes?

[note this is mostly for use within my nnimap groups]

Perhaps adding the header you want to nnmail-extra-headers works?

For me

(gnus-request-head "<sdwug0h2ds.fsf@wanderer.hardakers.net>"
                   "nnimap+yxa:INBOX.ding")

returns the headers of your message in the *nntpd* buffer, where you
can parse it to get the headers you want.

If you know the article number instead of message id, and you cache
articles in the agent, perhaps the agent will return what is cached.

Ah.  Thanks!  I'll try that.

Or that!
