|
|
;; Alert is a Growl-workalike for Emacs which uses a common notification
|
|||
|
|
;; interface and multiple, selectable "styles", whose use is fully
|
|||
|
|
;; customizable by the user.
|
|||
|
|
;;
|
|||
|
|
;; * For module writers
|
|||
|
|
;;
|
|||
|
|
;; Just use `alert' instead of `message' as follows:
|
|||
|
|
;;
|
|||
|
|
;; (require 'alert)
|
|||
|
|
;;
|
|||
|
|
;; ;; This is the most basic form usage
|
|||
|
|
;; (alert "This is an alert")
|
|||
|
|
;;
|
|||
|
|
;; ;; You can adjust the severity for more important messages
|
|||
|
|
;; (alert "This is an alert" :severity 'high)
|
|||
|
|
;;
|
|||
|
|
;; ;; Or decrease it for purely informative ones
|
|||
|
|
;; (alert "This is an alert" :severity 'trivial)
|
|||
|
|
;;
|
|||
|
|
;; ;; Alerts can have optional titles. Otherwise, the title is the
|
|||
|
|
;; ;; buffer-name of the (current-buffer) where the alert originated.
|
|||
|
|
;; (alert "This is an alert" :title "My Alert")
|
|||
|
|
;;
|
|||
|
|
;; ;; Further, alerts can have categories. This allows users to
|
|||
|
|
;; ;; selectively filter on them.
|
|||
|
|
;; (alert "This is an alert" :title "My Alert" :category 'debug)
|
|||
|
|
;;
|
|||
|
|
;; * For users
|
|||
|
|
;;
|
|||
|
|
;; For the user, there are several variables to control when and how alerts
|
|||
|
|
;; are presented. By default, they appear in the minibuffer much the same
|
|||
|
|
;; as a normal Emacs message. But there are many more possibilities:
|
|||
|
|
;;
|
|||
|
|
;; `alert-fade-time'
|
|||
|
|
;; Normally alerts disappear after this many seconds, if the style
|
|||
|
|
;; supports it. The default is 5 seconds.
|
|||
|
|
;;
|
|||
|
|
;; `alert-default-style'
|
|||
|
|
;; Pick the style to use if no other config rule matches. The
|
|||
|
|
;; default is `message', but `growl' works well too.
|
|||
|
|
;;
|
|||
|
|
;; `alert-reveal-idle-time'
|
|||
|
|
;; If a config rule choose to match on `idle', this is how many
|
|||
|
|
;; seconds idle the user has to be. Defaults to 5 so that users
|
|||
|
|
;; don't miss any alerts, but 120 is also good.
|
|||
|
|
;;
|
|||
|
|
;; `alert-persist-idle-time'
|
|||
|
|
;; After this many idle seconds, alerts will become sticky, and not
|
|||
|
|
;; fade away more. The default is 15 minutes.
|
|||
|
|
;;
|
|||
|
|
;; `alert-log-messages'
|
|||
|
|
;; By default, all alerts are logged to *Alerts* (and to *Messages*,
|
|||
|
|
;; if the `message' style is being used). Set to nil to disable.
|
|||
|
|
;;
|
|||
|
|
;; `alert-hide-all-notifications'
|
|||
|
|
;; Want alerts off entirely? They still get logged, however, unless
|
|||
|
|
;; you've turned that off too.
|
|||
|
|
;;
|
|||
|
|
;; `alert-user-configuration'
|
|||
|
|
;; This variable lets you control exactly how and when a particular
|
|||
|
|
;; alert, a class of alerts, or all alerts, get reported -- or if at
|
|||
|
|
;; all. Use this to make some alerts use Growl, while others are
|
|||
|
|
;; completely silent.
|
|||
|
|
;;
|
|||
|
|
;; * Programmatically adding rules
|
|||
|
|
;;
|
|||
|
|
;; Users can also programmatically add configuration rules, in addition to
|
|||
|
|
;; customizing `alert-user-configuration'. Here is one that the author
|
|||
|
|
;; currently uses with ERC, so that the fringe gets colored whenever people
|
|||
|
|
;; chat on BitlBee:
|
|||
|
|
;;
|
|||
|
|
;; (alert-add-rule :status '(buried visible idle)
|
|||
|
|
;; :severity '(moderate high urgent)
|
|||
|
|
;; :mode 'erc-mode
|
|||
|
|
;; :predicate
|
|||
|
|
;; #'(lambda (info)
|
|||
|
|
;; (string-match (concat "\\`[^&].*@BitlBee\\'")
|
|||
|
|
;; (erc-format-target-and/or-network)))
|
|||
|
|
;; :persistent
|
|||
|
|
;; #'(lambda (info)
|
|||
|
|
;; ;; If the buffer is buried, or the user has been
|
|||
|
|
;; ;; idle for `alert-reveal-idle-time' seconds,
|
|||
|
|
;; ;; make this alert persistent. Normally, alerts
|
|||
|
|
;; ;; become persistent after
|
|||
|
|
;; ;; `alert-persist-idle-time' seconds.
|
|||
|
|
;; (memq (plist-get info :status) '(buried idle)))
|
|||
|
|
;; :style 'fringe
|
|||
|
|
;; :continue t)
|
|||
|
|
;;
|
|||
|
|
;; * Builtin alert styles
|
|||
|
|
;;
|
|||
|
|
;; There are several builtin styles, and it is trivial to create new ones.
|
|||
|
|
;; The builtins are:
|
|||
|
|
;;
|
|||
|
|
;; fringe - Changes the current frame's fringe background color
|
|||
|
|
;; mode-line - Changes the current frame's mode-line background color
|
|||
|
|
;; gntp - Uses gntp, it requires gntp.el (see https://github.com/tekai/gntp.el)
|
|||
|
|
;; growl - Uses Growl on OS X, if growlnotify is on the PATH
|
|||
|
|
;; ignore - Ignores the alert entirely
|
|||
|
|
;; libnotify - Uses libnotify if notify-send is on the PATH
|
|||
|
|
;; log - Logs the alert text to *Alerts*, with a timestamp
|
|||
|
|
;; message - Uses the Emacs `message' facility
|
|||
|
|
;; notifications - Uses notifications library via D-Bus
|
|||
|
|
;; notifier - Uses terminal-notifier on OS X, if it is on the PATH
|
|||
|
|
;; osx-notifier - Native OSX notifier using AppleScript
|
|||
|
|
;; toaster - Use the toast notification system
|
|||
|
|
;;
|
|||
|
|
;; * Defining new styles
|
|||
|
|
;;
|
|||
|
|
;; To create a new style, you need to at least write a "notifier", which is
|
|||
|
|
;; a function that receives the details of the alert. These details are
|
|||
|
|
;; given in a plist which uses various keyword to identify the parts of the
|
|||
|
|
;; alert. Here is a prototypical style definition:
|
|||
|
|
;;
|
|||
|
|
;; (alert-define-style 'style-name :title "My Style's title"
|
|||
|
|
;; :notifier
|
|||
|
|
;; (lambda (info)
|
|||
|
|
;; ;; The message text is :message
|
|||
|
|
;; (plist-get info :message)
|
|||
|
|
;; ;; The :title of the alert
|
|||
|
|
;; (plist-get info :title)
|
|||
|
|
;; ;; The :category of the alert
|
|||
|
|
;; (plist-get info :category)
|
|||
|
|
;; ;; The major-mode this alert relates to
|
|||
|
|
;; (plist-get info :mode)
|
|||
|
|
;; ;; The buffer the alert relates to
|
|||
|
|
;; (plist-get info :buffer)
|
|||
|
|
;; ;; Severity of the alert. It is one of:
|
|||
|
|
;; ;; `urgent'
|
|||
|
|
;; ;; `high'
|
|||
|
|
;; ;; `moderate'
|
|||
|
|
;; ;; `normal'
|
|||
|
|
;; ;; `low'
|
|||
|
|
;; ;; `trivial'
|
|||
|
|
;; (plist-get info :severity)
|
|||
|
|
;; ;; Whether this alert should persist, or fade away
|
|||
|
|
;; (plist-get info :persistent)
|
|||
|
|
;; ;; Data which was passed to `alert'. Can be
|
|||
|
|
;; ;; anything.
|
|||
|
|
;; (plist-get info :data))
|
|||
|
|
;;
|
|||
|
|
;; ;; Removers are optional. Their job is to remove
|
|||
|
|
;; ;; the visual or auditory effect of the alert.
|
|||
|
|
;; :remover
|
|||
|
|
;; (lambda (info)
|
|||
|
|
;; ;; It is the same property list that was passed to
|

MESSAGE is what the user will see. You may also use keyword

arguments to specify additional details. Here is a full example:
|
|||
|
|
|
|||
|
|
\(alert \"This is a message\"

|
|
:severity \\='high ;; The default severity is `normal'

:title \"Title\" ;; An optional title
|
|||
|
|
:category \\='example ;; A symbol to identify the message
|
|||
|
|
:mode \\='text-mode ;; Normally determined automatically
|
|||
|
|
:buffer (current-buffer) ;; This is the default
|
|||
|
|
:data nil ;; Unused by alert.el itself
|
|||

|

|

;; it is best not to use this
|

:never-persist nil ;; Force this alert to never persist
|

|
|||
|
|
;; this is only for debugging!
|
|||
|
|
|
|||

|
If no :title is given, the buffer-name of :buffer is used. If
|
|||
|
|
:buffer is nil, it is the current buffer at the point of call.
|

|
|
|

:data is an opaque value which modules can pass through to their

|
|
own styles if they wish.
