Goto command for existing search windows

Goto command for existing search windows

[Mark Anderson]

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,

-Mark

I have a slightly better-for-me version now:

(defun notmuch-goto-or-search (&optional query)
  "Find a notmuch saved-search query with the given name, or a
search with the given query, switching to an existing buffer
without changes in preference to automatically refreshing or
creating the search buffer.

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 ((saved-search-tuple (assoc query notmuch-saved-searches)))
    (setq expanded-query
          (if (null saved-search-tuple)
              query
            (cdr saved-search-tuple))))
  (let ((buffer-name (notmuch-search-buffer-title expanded-query)))
    (setq buf (get-buffer buffer-name)))
    (if (not buf)
        (notmuch-search expanded-query)
      (switch-to-buffer buf)
      ))

This does search the saved searches to see if you entered a saved search
name.  With this I don't have to duplicate my query for saved searches
in key bindings.

(global-set-key [f8] (lambda () (interactive) (notmuch-goto-or-search "Inbox")))
(global-set-key [f9] (lambda () (interactive) (notmuch-goto-or-search "INBOX")))
(global-set-key [f10] (lambda () (interactive) (notmuch-goto-or-search "todo")))

Hey, Mark.  I think you can be a little simpler.  The title for search
buffers is based on the search, so a buffer will always be reused for an
identical search.  You don't need to do any fancy buffer searching.  For
instance, the following works perfectly for me, and I believe produces
the same results as your technique:

(defun jnotmuch-inbox ()
  "Search: inbox"
  (interactive)
  (notmuch-search "tag:inbox" t))
(define-key notmuch-hello-mode-map "2" 'jnotmuch-inbox)
(define-key notmuch-search-mode-map "2" 'jnotmuch-inbox)
(define-key notmuch-show-mode-map "2" 'jnotmuch-inbox)

jamie.

Hi, I believe Mark's point was just switching to the buffer if it
exists, *without* refreshing or doing the query, and only doing regular
notmuch-search if a buffer doesn't exist yet.

BR,
Jani.

I understand, but searches are so fast, particularly for searches that
you're doing frequently enough to map to a key binding, that I really
doubt it would ever be an issue.  It's certainly not for me.
