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. * Commands ** Global bindings | Keybinding | Command | |------------+------------| | ~SPC a M~ | Start mu4e | ** Headers mode | Keybinding | Command | |------------+-------------------------------------------------------------| | ~J~ | Go to next unread thread marking other mail read on the way | | ~C-j~ | Next header | | ~C-k~ | Previous header | ** View mode | Keybinding | Command | |------------+-------------------------------------------------------------| | ~J~ | Go to next unread thread marking other mail read on the way | | ~C-j~ | Next header | | ~C-k~ | Previous header | * 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 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. This extension is enabled by default, you can deactivate (and uninstall) it by adding the package == to your dotfile variable =dotspacemacs-excluded-packages=. ** Multiple Accounts This layer includes support for multiple sending accounts. If you have only one account you do not need to define this variable. If you have multiple accounts, configure the =mu4e-account-alist= variable: #+BEGIN_SRC emacs-lisp (setq mu4e-account-alist '(("gmail" ;; Under each account, set the account-specific variables you want. (mu4e-sent-messages-behavior delete) (mu4e-sent-folder "/gmail/[Gmail]/.Sent Mail") (mu4e-drafts-folder "/gmail/[Gmail]/.Drafts") (user-mail-address "billy@gmail.com") (user-full-name "Billy")) ("college" (mu4e-sent-messages-behavior sent) (mu4e-sent-folder "/college/Sent Items") (mu4e-drafts-folder "/college/Drafts") (user-mail-address "bb15@college.edu") (user-full-name "Billy Bob 15")))) (mu4e/mail-account-reset) #+END_SRC The first account listed will be the default account, so variables like =user-full-name=, which is used by other parts of Emacs, will have their value reset for the default account after sending each email. Note that the mu4e layer expects =mu4e-account-alist= to be defined before the layer is loaded. For example, you can set =mu4e-account-alist= to a dummy setting in =dotspacemacs/layers=: #+BEGIN_SRC emacs-lisp (mu4e :variables mu4e-account-alist t) #+END_SRC and then actually set =mu4e-account-alist= later in =dotspacemacs/user-config=. Make sure you call =mu4e/mail-account-reset= afterward, which will initialize the given account variables. If you have mu 0.9.16 or later, you can use mu4e's built-in contexts feature instead (see [[http://www.djcbsoftware.nl/code/mu/mu4e/Contexts.html#Contexts][mu4e's manual]]). ** 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 [[file:../../../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. 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"))) #+END_SRC * See also Refer to the official mu and mu4e documentation for additional info. - [[http://www.djcbsoftware.nl/code/mu/mu4e/index.html][mu4e Manual]]
