-#+TITLE: Ask for selection in Emacs

-I came across an email on one of the emacs mailing lists today, where
-someone asked how to ask a user for input whilst providing
-completions. The first answer he got was to try =tmm-prompt=, so I
-looked into it a little.
-
-I use =mu4e= as my primary email program, but since it isn't designed
-(seemingly) for use with multiple accounts I've got some wrapper
-functions that set some variables according to my liking and then
-start =mu4e=. This works very well, but it's a pain to have to use =M-x
-view-ryu-mail= or =M-x view-ninthfloor-mail= and such, so I wrote a
-function to read a string from the minibuffer, which I then bound to
-the ~<XF86Mail>~ key, this turned it into, for example =<XF86Mail> ryu=
-and =<XF86Mail> ninthfloor= and so on, but this doesn't have any
-completion or notification of my options.
-
-So after looking at ~tmm-prompt~ I came up with the following:
-
-#+BEGIN_SRC elisp
- (defvar oni:mailbox-map
- '(("ryulash.org" . "ryu")
- ("ninthfloor" . "ninthfloor"))
- "A mailbox map for use with `tmm-prompt'.")
-
- (defun view-ryu-mail ()...)
- (defun view-ninthfloor-mail ()...)
-
- (defun view-mu ()
- (interactive)
- (let* ((tmm-completion-prompt "Choose a mailbox\n")
- (inbox (tmm-prompt oni:mailbox-map)))
- (funcall (intern (concat "view-" inbox "-mail")))))
-#+END_SRC
-
-I've left out the definitions and some mail accounts for brevity.
-
-~tmm-prompt~ is usually used when using the text-mode menu with =M-` `=,
-but it works very well here too. This changes mailbox selection to,
-for example =<XF86Mail> r= or =<XF86Mail> n=.
