Process-marking all unread articles

Process-marking all unread articles

[Hrvoje Niksic]

I have a group with a bunch of ticked articles.  I'd like to create a
(keyboard) macro that tics all the new unread articles in the group.
That's not hard in itself -- just process-mark the unread articles,
then press `M-& !'.

However, I don't know how to do the "process-mark the unread articles"
bit.  I know I can process-mark and tick *all* the articles with
`M P b M-& !', but I'd like to avoid that because it would be quite
slow in a group with several hundred articles.

Any idea how to iterate over unread articles?

Does it work to narrow the buffer to the articles marked with SPC
first?

/ m SPC RET

This helps, thanks.  Now I can do the required operation with
something like `/m SPC RET M P b M-& !' optionally followed by `/w' to 
pop the process mark set.

But now I've gotten all cocky and would like to make the thing be a
Lisp function rather than a keyboard macro.  In that case `/m SPC RET' 
is replaced with a simple (gnus-summary-limit-to-marks " "), and `M P
b' with (gnus-uu-mark-buffer).  However, I don't know how to emulate
M-& followed by a command.

Is there a way to do what M-& does, but from Lisp, i.e. iterate
through process-marked articles in a way?

But you've forgotten to use Kai's patented `C-u 1000 !'  : )

The `gnus-summary-iterate' macro iterates over the process/prefixed
articles and executes a form:

(gnus-summary-iterate arg
  (stuff)
  (more stuff))
