couple of questions about api

[Nikola Pajkovsky]

Hey folks,

Let's say I have these mails in summary

   [  31: Mark Brown  ] [PATCH 0/5] mfd: arizona: Updates for v3.7
       [ 553: Mark Brown  ] [PATCH 1/5] mfd: wm5102: Update register patch for latest evaluation
           [  27: Mark Brown  ] [PATCH 2/5] mfd: wm5110: Disable control interface error report for WM5110 rev B
           [  34: Mark Brown  ] [PATCH 3/5] mfd: arizona: Use correct array for ARRAY_SIZE in mfd_add_devices call
           [  37: Mark Brown  ] [PATCH 4/5] mfd: arizona: Correctly report when AIF2/AIF1 is underclocked
           [  45: Mark Brown  ] [PATCH 5/5] mfd: arizona: Sync regcache after reset

I found the function gnus-fetch-field which works fine in Article
buffer, but not in Summary buffer. See code

(global-set-key (kbd "\C-xpg") 'get-message-id)

(defun get-message-id ()
  (car (nthcdr 1 (mail-extract-address-components
		  (gnus-fetch-field "message-id")))))


What do I have to call to get message-id from mail header from Summary
buffer?

And how to make it work with process markers? I'd like to mark some mail
and get message-id one by one.

Thanks

Perhaps there's something that feels cleaner but I've always used something like 

(save-excursion (set-buffer gnus-article-buffer) ...)

See the function gnus-summary-work-articles

You can use `(mail-header-id (gnus-summary-article-header))' from the
summary buffer to get the id. That's probably as clean as it gets...

When messing with articles in the summary buffer, I've found one of the
best approaches is to use the variable `gnus-newsgroup-data', which
contains a list of small data structures representing all the visible
messages. The data structures contain the article number and the basic
headers (including Message-Id) for each message, and there's a set of
`gnus-data-*' functions for working with those structures. Similar
structures show up repeatedly with different functions -- the
`gnus-summary-article-header' function I mentioned above returns
something very like a `gnus-newsgroup-data' entry for the message under
point, and many other functions know what to do with those entries.

Good to know about `gnus-summary-work-articles', I hadn't got that far
yet...

Or (with-current-buffer gnus-article-buffer ...).

The gnus-registry needed these functions too, since it works with
message IDs primarily.  Take a look, especially at the registry mark
commands.
