+
+;;; Commentary:
+;;; * description
+;; ampc is a controller for the Music Player Daemon (http://mpd.wikia.com/).
+
+;;; ** installation
+;; If you use GNU ELPA, install ampc via M-x package-list-packages RET or
+;; (package-install 'ampc). Otherwise, grab the files in this repository and
+;; put the Emacs Lisp ones somewhere in your load-path or add the directory the
+;; files are in to it, e.g.:
+;;
+;; (add-to-list 'load-path "~/.emacs.d/ampc")
+;; (autoload 'ampc "ampc" nil t)
+;;
+;; Byte-compile ampc (M-x byte-compile-file RET /path/to/ampc.el RET) to
improve
+;; its performance!
+
+;;; *** tagger
+;; ampc is not only a frontend to MPD but also a full-blown audio file tagger.
+;; To use this feature you have to build the backend application,
`ampc_tagger',
+;; which in turn uses TagLib (http://taglib.github.com/), a dual-licended
+;; (LGPL/MPL) audio meta-data library written in C++. TagLib has no
+;; dependencies on its own.
+;;
+;; To build `ampc_tagger', locate ampc_tagger.cpp. The file can be found in
the
+;; directory in which this file, ampc.el, is located. Compile the file and
+;; either customize `ampc-tagger-executable' to point to the binary file or
move
+;; the executable in a suitable directory so Emacs finds it via consulting
+;; `exec-path'.
+;;
+;; g++ -O2 ampc_tagger.cpp -oampc_tagger -ltag && sudo cp ampc_tagger
/usr/local/bin && rm ampc_tagger
+;;
+;; You have to customize `ampc-tagger-music-directories' in order to use the
+;; tagger. This variable should be a list of directories in which your music
+;; files are located. Usually this list should have only one entry, the value
+;; of your mpd.conf's `music_directory'.
+;;
+;; If `ampc-tagger-backup-directory' is non-nil, the tagger saved copies of all
+;; files that are about to be modified to this directory. Emacs's regular
+;; numeric backup filename syntax is used for the backup file names. By
default
+;; `ampc-tagger-backup-directory' is set to "~/.emacs.d/ampc-backups/".
+
+;;; ** usage
+;; To invoke ampc call the command `ampc', e.g. via M-x ampc RET. The first
+;; argument to `ampc' is the host, the second is the port. Both values default
+;; to nil. If nil, ampc will use the value specified in `ampc-default-server',
+;; by default localhost:6600. To make ampc use the full frame rather than the
+;; selected window for its window setup, customise `ampc-use-full-frame' to a
+;; non-nil value.
+;;
+;; ampc offers three independent views which expose different parts of the user
+;; interface. The current playlist view, the default view at startup, may be
+;; accessed using the `J' key (that is `S-j'). The playlist view may be
+;; accessed using the `K' key. The outputs view may be accessed by pressing
+;; `L'.
+
+;;; *** current playlist view
+;; The playlist view looks like this:
+;;
+;; .........................
+;; . 1 . 3 . 4 . 5 .
+;; .......... . . .
+;; . 2 . . . .
+;; . . . . .
+;; . . . . .
+;; . ................
+;; . . 6 .
+;; . . .
+;; .........................
+;;
+;; Window one exposes basic information about the daemon, such as the current
+;; state (stop/play/pause), the song currently playing or the volume.
+;;
+;; All windows, except the status window, contain a tabular list of items.
Each
+;; item may be selected/marked. There may be multiple selections.
+;;
+;; To mark an entry, move the point to the entry and press `m' (ampc-mark). To
+;; unmark an entry, press `u' (ampc-unmark). To unmark all entries, press `U'
+;; (ampc-unmark-all). To toggle marks, press `t' (ampc-toggle-marks).
Pressing
+;; `<down-mouse-1>' with the mouse mouse cursor on a list entry will move point
+;; to the entry and toggle the mark. To navigate to the next entry, press `n'
+;; (ampc-next-line). Analogous, pressing `p' (ampc-previous-line) moves the
+;; point to the previous entry.
+;;
+;; Window two shows the current playlist. The song that is currently played by
+;; the daemon, if any, is highlighted. To delete the selected songs from the
+;; playlist, press `d' (ampc-delete). Pressing `<down-mouse-3>' will move the
+;; point to the entry under cursor and delete it from the playlist. To move
the
+;; selected songs up, press `<up>' (ampc-up). Analogous, press `<down>'
+;; (ampc-down) to move the selected songs down. Pressing `<return>'
+;; (ampc-play-this) or `<down-mouse-2>' will play the song at point/cursor.
+;;
+;; Windows three to five are tag browsers. You use them to narrow the song
+;; database to certain songs. Think of tag browsers as filters, analogous to
+;; piping `grep' outputs through additional `grep' filters. The property of
the
+;; songs that is filtered is displayed in the header line of the window.
+;;
+;; Window six shows the songs that match the filters defined by windows three
to
+;; five. To add the selected song to the playlist, press `a' (ampc-add).
+;; Pressing `<down-mouse-3>' will move the point to the entry under the cursor
+;; and execute `ampc-add'. These key bindings works in tag browsers as well.
+;; Calling `ampc-add' in a tag browser adds all songs filtered up to the
+;; selected browser to the playlist.
+;;
+;; The tag browsers of the current playlist view (accessed via `J') are `Genre'
+;; (window 3), `Artist' (window 4) and `Album' (window 5). The key `M' may be
+;; used to fire up a slightly modified current playlist view. There is no
+;; difference to the default current playlist view other than that the tag
+;; browsers filter to `Genre' (window 3), `Album' (window 4) and `Artist'
+;; (window 5). Metaphorically speaking, the order of the `grep' filters
defined
+;; by the tag browsers is different.
+
+;;; *** playlist view
+;; The playlist view resembles the current playlist view. The window, which
+;; exposes the playlist content, is replaced by three windows, vertically
+;; arragned, though. The top one still shows the current playlist. The bottom
+;; one shows a list of stored playlists. The middle window exposes the content
+;; of the selected (stored) playlist. All commands that used to work in the
+;; current playlist view and modify the current playlist now modify the
selected
+;; (stored) playlist unless the point is within the current playlist buffer.
+;; The list of stored playlists is the only view in ampc that may have only one
+;; marked entry.
+;;
+;; To queue a playlist, press `l' (ampc-load) or `<down-mouse-2>'. To delete a
+;; playlist, press `d' (ampc-delete-playlist) or `<down-mouse-3>'. The command
+;; `ampc-rename-playlist', bound to `r', can be used to rename a playlist.
+;;
+;; Again, the key `<' may be used to setup a playlist view with a different
+;; order of tag browsers.
+
+;;; *** outputs view
+;; The outputs view contains a single list which shows the configured outputs
of
+;; MPD. To toggle the enabled property of the selected outputs, press `a'
+;; (ampc-toggle-output-enabled) or `<mouse-3>'.
+
+;;; ** tagger
+;; To start the tagging subsystem, press `I' (ampc-tagger). This key binding
+;; works in every buffer associated with ampc. First, the command tries to
+;; determine which files you want to tag. The files are collected using either
+;; the selected entries within the current buffer, the file associated with the
+;; entry at point, or, if both sources did not provide any files, the audio
file
+;; that is currently played by MPD. Next, the tagger view is created. On the
+;; right there is the buffer that contain the tag data. Each line in this
+;; buffer represents a tag with a value. Tag and value are separated by a
+;; colon. Valid tags are "Title", "Artist", "Album", "Comment", "Genre",
"Year"
+;; and "Track". The value can be an arbitrary string. Whitespaces in front
and
+;; at the end of the value are ignored. If the value is "<keep>", the tag line
+;; is ignored.
+;;
+;; To save the specified tag values back to the files, press `C-c C-c'
+;; (ampc-tagger-save). To exit the tagger and restore the previous window
+;; configuration, press `C-c C-q'. `C-u C-c C-c' saved the tags and exits the
+;; tagger. Only tags that are actually specified within the tagger buffer
+;; written back to the file. Other tags will not be touched by ampc. For
+;; example, to clear the "Commentary" tag, you need to specify the line
+;;
+;; Commentary:
+;;
+;; In the tagger buffer. Omitting this line will make the tagger not touch the
+;; "Commentary" tag at all.
+;;
+;; On the right there is the files list buffer. The selection of this buffer
+;; specifies which files the command `ampc-tag-save' will write to. If no file
+;; is selected, the file at point in the file list buffer is used.
+;;
+;; To reset the values of the tags specified in the tagger buffer to the common
+;; values of all selected files specified by the selection of the files list
+;; buffer, press `C-c C-r' (ampc-tagger-reset). With a prefix argument,
+;; `ampc-tagger-reset' restores missing tags as well.
+;;
+;; You can use tab-completion within the tagger buffer for both tags and tag
+;; values.
+;;
+;; You can also use the tagging subsystem on its own without a running ampc
+;; instance. To start the tagger, call `ampc-tag-files'. This function
accepts
+;; one argument, a list of absolute file names which are the files to tag.
ampc
+;; provides a minor mode for dired, `ampc-tagger-dired-mode'. If this mode is
+;; enabled within a dired buffer, pressing `C-c C-t' (ampc-tagger-dired) will
+;; start the tagger on the current selection.
+;;
+;; The following ampc-specific hooks are run during tagger usage:
+;;
+;; `ampc-tagger-grab-hook': Run by the tagger before grabbing tags of a file.
+;; Each function is called with one argument, the file name.
+;;
+;; `ampc-tagger-grabbed-hook': Run by the tagger after grabbing tags of a file.
+;; Each function is called with one argument, the file name.
+;;
+;; `ampc-tagger-store-hook': Run by the tagger before writing tags back to a
+;; file. Each function is called with two arguments, FOUND-CHANGED and DATA.
+;; FOUND-CHANGED is non-nil if the tags that are about to be written differ
from
+;; the ones in the file. DATA is a cons. The car specifies the full file name
+;; of the file that is about to be written to, the cdr is an alist that
+;; specifies the tags that are about to be (over-)written. The car of each
+;; entry in this list is a symbol specifying the tag (one of the ones in
+;; `ampc-tagger-tags'), the cdr a string specifying the value. The cdr of DATA
+;; may be modified. If FOUND-CHANGED is nil and the cdr of DATA is not
modified
+;; throughout the hook is run, the file is not touched.
+;; `ampc-tagger-stored-hook' is still run, though.
+;;
+;; `ampc-tagger-stored-hook': Run by the tagger after writing tags back to a
+;; file. Each function is called with two arguments, FOUND-CHANGED and DATA.
+;; These are the same arguments that were already passed to
+;; `ampc-tagger-store-hook'. The car of DATA, the file name, may be modified.
+;;
+;; These hooks can be used to handle vc locking and unlocking of files. For
+;; renaming files according to their (new) tag values, ampc provides the
+;; function `ampc-tagger-rename-artist-title' which may be added to
+;; `ampc-tagger-stored-hook'. The new file name generated by this function is
+;; "Artist"_-_"Title"."extension". Characters within "Artist" and "Title" that
+;; are not alphanumeric are substituted with underscores.
+
+;;; ** global keys
+;; Aside from `J', `M', `K', `<' and `L', which may be used to select different
+;; views, and `I' which starts the tagger, ampc defines the following global
+;; keys. These binding are available in every buffer associated with ampc:
+;;
+;; `k' (ampc-toggle-play): Toggle play state. If MPD does not play a song,
+;; start playing the song at point if the current buffer is the playlist
buffer,
+;; otherwise start at the beginning of the playlist. With numeric prefix
+;; argument 4, stop player rather than pause if applicable.
+;;
+;; `l' (ampc-next): Play next song.
+;; `j' (ampc-previous): Play previous song
+;;
+;; `c' (ampc-clear): Clear playlist.
+;; `s' (ampc-shuffle): Shuffle playlist.
+;;
+;; `S' (ampc-store): Store playlist.
+;; `O' (ampc-load): Load selected playlist into the current playlist.
+;; `R' (ampc-rename-playlist): Rename selected playlist.
+;; `D' (ampc-delete-playlist): Delete selected playlist.
+;;
+;; `y' (ampc-increase-volume): Increase volume.
+;; `M-y' (ampc-decrease-volume): Decrease volume.
+;; `C-M-y' (ampc-set-volume): Set volume.
+;; `h' (ampc-increase-crossfade): Increase crossfade.
+;; `M-h' (ampc-decrease-crossfade): Decrease crossfade.
+;; `C-M-h' (ampc-set-crossfade): Set crossfade.
+;;
+;; `e' (ampc-toggle-repeat): Toggle repeat state.
+;; `r' (ampc-toggle-random): Toggle random state.
+;; `f' (ampc-toggle-consume): Toggle consume state.
+;;
+;; `P' (ampc-goto-current-song): Select the current playlist window and move
+;; point to the current song.
+;; `G' (ampc-mini): Select song to play via `completing-read'.
+;;
+;; `T' (ampc-trigger-update): Trigger a database update.
+;; `Z' (ampc-suspend): Suspend ampc.
+;; `q' (ampc-quit): Quit ampc.
+;;
+;; The keymap of ampc is designed to fit the QWERTY United States keyboard
+;; layout. If you use another keyboard layout, feel free to modify
+;; `ampc-mode-map'. For example, I use a regular QWERTZ German keyboard
+;; (layout), so I modify `ampc-mode-map' in my init.el like this:
+;;
+;; (eval-after-load 'ampc
+;; '(flet ((substitute-ampc-key
+;; (from to)
+;; (define-key ampc-mode-map to (lookup-key ampc-mode-map from))
+;; (define-key ampc-mode-map from nil)))
+;; (substitute-ampc-key (kbd "z") (kbd "Z"))
+;; (substitute-ampc-key (kbd "y") (kbd "z"))
+;; (substitute-ampc-key (kbd "M-y") (kbd "M-z"))
+;; (substitute-ampc-key (kbd "C-M-y") (kbd "C-M-z"))
+;; (substitute-ampc-key (kbd "<") (kbd ";"))))
+;;
+;; If ampc is suspended, you can still use every interactive command that does
+;; not directly operate on or with the user interace of ampc. For example it
is
+;; perfectly fine to call `ampc-increase-volume' or `ampc-toggle-play' via M-x
+;; RET. Especially the commands `ampc-status' and `ampc-mini' are
predesignated
+;; to be bound in the global keymap and called when ampc is suspended.
+;; `ampc-status' messages the information that is displayed by the status
window
+;; of ampc. `ampc-mini' lets you select a song to play via `completing-read'.
+;; To start ampc suspended, call `ampc' with the third argument being non-nil.
+;; To check whether ampc is connected to the daemon and/or suspended, call
+;; `ampc-is-on-p' or `ampc-suspended-p'.
+;;
+;; (global-set-key (kbd "<f7>")
+;; (lambda ()
+;; (interactive)
+;; (unless (ampc-on-p)
+;; (ampc nil nil t))
+;; (ampc-status)))
+;; (global-set-key (kbd "<f8>")

+;; (interactive)
+;; (unless (ampc-on-p)
