filtering mail from a group

[Erik Colson]

Hi,

How can I create some kind of search-group which would show only
articles from a specific group which were posted after a specific date ?

thanks

You can use / t (gnus-summary-limit-to-age).

Thanks for your answer. This is certainly an option, but I'd like to
have some kind of 'virtual group' which would only show those messages
satisfying the filter...

If not possible I'd go with / t

Thanks

Hi Erik.

Well, Gnus have virtual groups but these are a collection of other
groups (normally small groups). Maybe what you want is what is called
*Splitting mail* in Gnus. I recommend you to read the section *Splitting
Mail* and related sections from the Gnus Manual. If you don't understand
something or have troubles, I can try to help you.

Hi Sergio!

Thanks for your answer!
I don't want to put mails in another mailbox. I want to limit the mails
to mails posted after a certain date, without removing the older ones
from the mailbox. It is doable with / t but that makes me calculate
again and again the number of days since the 'filter date'. Because / t
requires to enter a number of days and not a date...

Thanks for helping !

OK, maybe this can help you:

---------------------------------------------------------------
(defun gnus-summary-limit-to-date (date &optional after-p)
  "Limit the summary buffer to articles before DATE.
If AFTER-P (the prefix) is non-nil, limit the summary buffer to
articles that are after DATE."
  (interactive 
   (let ((after current-prefix-arg)
	 date-string)
     (setq date-string
	   (if after
	       (read-string "Limit to after the date: ")
	     (read-string "Limit to before the date: ")))
     (list date-string after)))
  (let (date-string age)
    (setq date-string
	  (if (string-match-p ":+" date)
	      date
	    (concat date " 00:00" )))
    (setq age (days-between (current-time-string) date-string))
    (gnus-summary-limit-to-age age after-p)))
----------------------------------------------------------------

Put this in your .emacs or .gnus file, then in the summary buffer do
M-x gnus-summary-limit-to-date RET.
It prompts you for a date to limit articles before that date or after if
a prefix argument is given (i.e. C-u M-x gnus-summary-limit-to-date RET).

Note that the date is in a format accepted by `parse-time-string', for
example: "2012-01-01" or "Mon, 30 Apr 2012 22:40:05 -0500", etc.

I hope this can be useful. Let me know if it does not fit your needs.
