Goto command for existing search windows

[Mark Anderson <MarkR.Anderson@amd.com>]

I was looking for a function which would find a buffer based on one of
my saved searches, and perform the search if it didn't exist.

I've gotten it a bit closer, if I perform the search that matches a
saved search, then this routine will find it because of the magic in
notmuch-search-buffer-title, but perhaps someone else feels up to
searching through the saved searches directly?



(defun notmuch-goto-or-search (&optional query)
  "Find a notmuch-search buffer with the given query, or run 
\"notmuch search\" with the given `query' and display results.

If `query' is nil, it is read interactively from the minibuffer."
  (interactive)
  (if (null query)
      (setq query (notmuch-read-query "Notmuch goto-or-search: ")))
  (let ((buffer-name (notmuch-search-buffer-title query)))
    (setq buf (get-buffer buffer-name)))
              
    (if (not buf)
        (notmuch-search query)
      (switch-to-buffer buf)
      )))

I then use it something like this:

(global-set-key [C-f1] (lambda () (interactive) (notmuch-goto-or-search "tag:inbox and tag:unread and not tag:deleted")))
(global-set-key [C-f2] (lambda () (interactive) (notmuch-goto-or-search "tag:inbox and not tag:deleted")))
(global-set-key [C-f3] 'notmuch)
(global-set-key [C-f6] (lambda () (interactive) (notmuch-goto-or-search "tag:todo and not tag:deleted")))

It would be better if I could use my Inbox, INBOX and todo names for the
saved searches, but how to do that without breaking generality of
searching the body of the email?  Do I have to define my own ss: (saved
search) prefix or something, as I believe some others have?

This is what I'm willing to do today, and it works for me, I could patch
notmuch.el, but I wondered about answering the other questions.

Also, some elisp master could hint about how to make the binding not so
ugly. ;)

Another appreciated elisp hint would be how to get the buf variable to
go inside the let, I keep getting complaints about buffer-name not being
defined, thus the "ugly" setq, which works.

Enjoy,
