* Description
|
||
This layer adds support for the Mu4e email client.
|
||
|
||
** Features:
|
||
- Search, read, reply, move, and delete email.
|
||
- Search-based: no folders, only queries.
|
||
- UI optimized for speed: quick keystrokes for common actions.
|
||
- Very extendable and costumizable.
|
||
- Integration with Helm.
|
||
- Maildir summary using [[https://github.com/agpchil/mu4e-maildirs-extension][mu4e-mailidrs-extension]]
|
||
- Notifications using [[https://github.com/iqbalansari/mu4e-alert][mu4e-alert]]
|
||
|
||
* Install
|
||
In order to use this layer you must install mu and mu4e separately. Typically
|
||
mu4e will be bundled with mu (this is the case on many Linux distributions).
|
||
|
||
If you’re on OS X and install mu using Homebrew, you must specify the
|
||
location of your Emacs binary at install time using the EMACS environment
|
||
variable, as well as passing the =--with-emacs= option:
|
||
|
||
#+BEGIN_SRC shell
|
||
brew install mu --with-emacs
|
||
#+END_SRC
|
||
|
||
If the installation directory of mu4e is not in Emacs’ load path, you can set
|
||
the layer variable =mu4e-installation-path=, for example:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq-default dotspacemacs-configuration-layers
|
||
'((mu4e :variables
|
||
mu4e-installation-path "/usr/share/emacs/site-lisp")))
|
||
#+END_SRC
|
||
|
||
Then add this layer to your =~/.spacemacs=. You will need to add =mu4e= to the
|
||
existing =dotspacemacs-configuration-layers= list in this file.
|
||
|
||

* Configuration
|
||
Configuration varies too much to give precise instructions. What follows is one
|
||
example configuration. Refer to mu4e’s manual for more detailed configuration
|
||
instructions.
|
||
|
||
** Maildirs extension
|
||
The [[https://github.com/agpchil/mu4e-maildirs-extension][maildirs extension]] adds a list of all your maildirs to the main mu4e view
|
||
that by default shows the unread and total mail counts for all your mail under
|
||
your base mail directory.
|
||
|
||
The maildirs extension is not enabled by default. To activate it, change the
|
||
variable =mu4e-use-maildirs-extension= to a non-nil value:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq-default dotspacemacs-configuration-layers
|
||
'((mu4e :variables
|
||
mu4e-use-maildirs-extension t)))
|
||
#+END_SRC
|
||
|
||
** Multiple Accounts
|
||
With `mu 0.9.16`, mu4e comes with a native contexts feature for managing
|
||
multiple accounts.
|
||
|
||
The following example is taken from the manual:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq mu4e-contexts
|
||
`( ,(make-mu4e-context
|
||
:name "Private"
|
||
:enter-func (lambda () (mu4e-message "Switch to the Private context"))
|
||
;; leave-func not defined
|
||
:match-func (lambda (msg)
|
||
(when msg
|
||
(mu4e-message-contact-field-matches msg
|
||
:to "aliced@home.example.com")))
|
||
:vars '( ( user-mail-address . "aliced@home.example.com" )
|
||
( user-full-name . "Alice Derleth" )
|
||
( mu4e-compose-signature .
|
||
(concat
|
||
"Alice Derleth\n"
|
||
"Lauttasaari, Finland\n"))))
|
||
,(make-mu4e-context
|
||
:name "Work"
|
||
:enter-func (lambda () (mu4e-message "Switch to the Work context"))
|
||
;; leave-fun not defined
|
||
:match-func (lambda (msg)
|
||
(when msg
|
||
(mu4e-message-contact-field-matches msg
|
||
:to "aderleth@miskatonic.example.com")))
|
||
:vars '( ( user-mail-address . "aderleth@miskatonic.example.com" )
|
||
( user-full-name . "Alice Derleth" )
|
||
( mu4e-compose-signature .
|
||
(concat
|
||
"Prof. Alice Derleth\n"
|
||
"Miskatonic University, Dept. of Occult Sciences\n"))))))
|
||
|
||
;; set `mu4e-context-policy` and `mu4e-compose-policy` to tweak when mu4e should
|
||
;; guess or ask the correct context, e.g.
|
||
|
||
;; start with the first (default) context;
|
||
;; default is to ask-if-none (ask when there's no context yet, and none match)
|
||
;; (setq mu4e-context-policy 'pick-first)
|
||
|
||
;; compose with the current context is no context matches;
|
||
;; default is to ask
|
||
;; '(setq mu4e-compose-context-policy nil)
|
||
#+END_SRC
|
||
|
||
Note: We used to have a hack to support multiple accounts with older version of
|
||
`mu` but we removed it to encourage people to update their version and use the
|
||
new contexts feature.
|
||
|
||
** Async mode
|
||
mu4e can send mails in async mode, which speeds up sending as you do not have
|
||
to wait for the email to be sent. This is off by default but you can enable
|
||
it by setting the ~mu4e-enable-async-operations~ variable when including the
|
||
layer.
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq-default dotspacemacs-configuration-layers
|
||
'((mu4e :variables
|
||
mu4e-enable-async-operations t)))
|
||
#+END_SRC
|
||
|
||
** Attachment directory
|
||
By default mu4e will save attachment files to $HOME, but this layer changes
|
||
that to $HOME/Downloads if it exists. You can override this in your user-config:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq mu4e-attachment-dir "~/files")
|
||
#+END_SRC
|
||
|
||
** Example configuration
|
||
#+BEGIN_SRC emacs-lisp
|
||
;;; Set up some common mu4e variables
|
||
(setq mu4e-maildir "~/.mail"
|
||
mu4e-trash-folder "/Trash"
|
||
mu4e-refile-folder "/Archive"
|
||
mu4e-get-mail-command "mbsync -a"
|
||
mu4e-update-interval nil
|
||
mu4e-compose-signature-auto-include nil
|
||
mu4e-view-show-images t
|
||
mu4e-view-show-addresses t)
|
||
|
||
;;; Mail directory shortcuts
|
||
(setq mu4e-maildir-shortcuts
|
||
'(("/gmail/INBOX" . ?g)
|
||
("/college/INBOX" . ?c)))
|
||
|
||
;;; Bookmarks
|
||
(setq mu4e-bookmarks
|
||
`(("flag:unread AND NOT flag:trashed" "Unread messages" ?u)
|
||
("date:today..now" "Today's messages" ?t)
|
||
("date:7d..now" "Last 7 days" ?w)
|
||
("mime:image/*" "Messages with images" ?p)
|
||
(,(mapconcat 'identity
|
||
(mapcar
|
||
(lambda (maildir)
|
||
(concat "maildir:" (car maildir)))
|
||
mu4e-maildir-shortcuts) " OR ")
|
||
"All inboxes" ?i)))
|
||
#+END_SRC
|
||
|
||
** Notifications
|
||
=mu4e-alert= is an extension that provides desktop notifications and adds the
|
||
count of unread messages to the modeline.
|
||
|
||
[[https://raw.githubusercontent.com/iqbalansari/mu4e-alert/master/screenshots/mu4e-alert-in-action.png]]
|
||
|
||
For an extended documentation of the available customizations please refer to
|
||
[[https://github.com/iqbalansari/mu4e-alert#user-content-customizations][mu4e-alert’s documentation]]
|
||
|
||
*** OS notifications
|
||
To enable notifications about new messages, add the following line to your
|
||
=dotspacemacs/user-config=:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq mu4e-enable-notifications t)
|
||
#+END_SRC
|
||
|
||
or use layer variables when you add the layer to
|
||
=dotspacemacs-configuration-layers=:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(mu4e :variables mu4e-enable-notifications t)
|
||
#+END_SRC
|
||
|
||
By default, notifications will be shown in the =*Messages*= buffer. To enable
|
||
desktop notifications about new messages, add the following lines to
|
||
your =dotspacemacs/user-config=, according to your operating system and the
|
||
installed libraries:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(with-eval-after-load 'mu4e-alert
|
||
;; Enable Desktop notifications
|
||
(mu4e-alert-set-default-style 'notifications)) ; For linux
|
||
;; (mu4e-alert-set-default-style 'libnotify)) ; Alternative for linux
|
||
;; (mu4e-alert-set-default-style 'notifier)) ; For Mac OSX (through the
|
||
; terminal notifier app)
|
||
;; (mu4e-alert-set-default-style 'growl)) ; Alternative for Mac OSX
|
||
#+END_SRC
|
||
|
||
*** Mode-line notifications
|
||
To enable mode-line display about new messages, add the following line to
|
||
your =dotspacemacs/user-config=:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq mu4e-enable-mode-line t)
|
||
#+END_SRC
|
||
|
||
or use layer variables when you add the layer to
|
||
=dotspacemacs-configuration-layers=:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(mu4e :variables mu4e-enable-mode-line t)
|
||
#+END_SRC
|
||
|
||
** Spacemacs layout integration
|
||
A [[https://github.com/syl20bnr/spacemacs/blob/develop/doc/DOCUMENTATION.org#layouts-and-workspaces][Spacemacs custom layout]] is defined by the layer. The name and the key binding
|
||
for it can be customized with the following layer variables:
|
||
- =mu4e-spacemacs-layout-name= for the layout name,
|
||
- =mu4e-spacemacs-layout-binding= for the key binding.
|
||
- =mu4e-spacemacs-kill-layout-on-exit= for automatically removing layout when quitting mu4e.
|
||
|
||
By default the values are:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq-default dotspacemacs-configuration-layers
|
||
'((mu4e :variables mu4e-spacemacs-layout-name "@Mu4e"
|
||
mu4e-spacemacs-layout-binding "m"
|
||
mu4e-spacemacs-kill-layout-on-exit t)))
|
||
#+END_SRC
|
||
