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:
[[!format el """
(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")))))
"""]]
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`.
