It tries to be a clean and -small application to play multimedia files from Emacs using external -players. Many of its ideas are derived from MpthreePlayer -(http://www.nongnu.org/mp3player), but it tries to be more general and -more clean. - - The basic functionality of Emms consists of three parts: The core, -the sources, and the players. - - The core resides in `emms.el', and provides a simple playlist and -the basic functionality to use all the other features of Emms. It -provides the common user commands and interfaces for other parts. It -thinks in tracks, where a track is the combination of a type and a -name--e.g., the track type 'file has a name that is the file name. -Other track types are possible. - - To get to tracks, the core needs sources. The file -`emms-source-file.el' provides simple sources to interact with the -file system. - - When Emms finally has the sources in the playlist, it needs a -player to play them. `emms-player-simple.el' defines a few useful -players, and allows you to define your own in a very simple way. - - The way Emms works is easy to customize with your own code or by -using `M-x customize RET'. - - -* Installation -============== - -You need to put all the .el files of EMMS in a directory in your -load-path. For example, if you put all those files into -~/elisp/emms/, then in your ~/.emacs you should do: - -(add-to-list 'load-path "~/elisp/emms/") - -For information about compiling Emms into byte-code see the -``Compiling Emms'' section in the Emms manual. - -** Setup --------- -After adding the location of the Emms code to the load-path variable, -we invoke the following using the `emms-setup' feature which allows -for quick and simple Emms setup. - - (require 'emms-setup) - (emms-standard) - (emms-default-players) - -After which Emms is set up and ready to go! - - For more information about different setup levels and features see -the ``Simple Setup'' section of the Emms manual. - -** Usage --------- -The basic functionality of EMMS is just to play music without being -noticed. It provides a few commands to skip the current track and -such, but otherwise, it doesn't show up. EMMS provides the following -basic user commands (that you might want to bind to keys): - -emms-start ...... Start playing the current playlist -emms-stop ....... Stop playing -emms-next ....... Go to the next track in the playlist -emms-previous ... Go to the previous track in the playlist -emms-shuffle .... Shuffle the playlist -emms-show ....... What is playing? - -But before you can use these, you need a playlist to start with. The -following commands allow you to create a playlist from different -sources: - -emms-play-file ............. Play a single file -emms-play-directory ........ Play a whole directory -emms-play-directory-tree ... Play a directory tree - - -* The Interactive Playlist buffer -================================= - -Emms provides a visual, interactive playlist mode as well as the -ability to use playlists without ever looking at them. This visual, -interactive mode is called the `emms-playlist-mode' and is defined in -`emms-playlist-mode.el'. - - To use the interactive playlist invoke: `M-x emms-playlist-mode-go -RET' - - When in the interactive playlist mode we can perform different -actions on the current playlist. Here are some basic commands: - -`n'....Start playing the next track in the playlist. - -`p'....Start playing the previous track in the playlist. - -`s'....Stop playing. - -`f'....Describe the currently playing track in the minibuffer. - -`c'....Display the current track in the center of the screen. - -`RET'..Start playing the track under point. Note that this is also - available with `Mouse-2'. - -`q'....Put the interactive playlist buffer at the end of the list of - all buffers (i.e., bury it). - -As always, for more commands see the mode documentation and the -``Interactive Playlists'' section of the Emms manual. - - -* Bare Bones Setup -================== - -The following code fragment provides a minimal EMMS setup without -using the layer of `emms-default'. It can maybe be used to better -understand the internals of EMMS. You can see how EMMS needs to know -about players (these are defined in `emms-player-simple') and about -sources for tracks (trivial file system based sources, such as this -`emms-directory-tree', are defined in `emms-source-file'). - -(require 'emms-player-simple) -(require 'emms-source-file) -(require 'emms-source-playlist) -(setq emms-player-list '(emms-player-mpg321 - emms-player-ogg123 - emms-player-mplayer)) - - -* Advanced configuration -======================== - -** Seeking ----------- -In most multimedia players, you can seek forward or backward in a -track. EMMS supports this too. If you're using mplayer, check that -`emms-player-mplayer-parameters' contains ``slave''. If you're using -mpg321, there is a module called emms-player-mpg321-remote.el. To use -it, simply add the following lines to your configuration: - -(require 'emms-player-mpg321-remote) -(push 'emms-player-mpg321-remote emms-player-list) - -Finally, if you are using mpd, no special config is needed. - - Seeking works through the following functions: - -`emms-seek' which takes a negative or positive amount of seconds. -`emms-seek-forward' which seeks ten seconds forward. -`emms-seek-backward' which seeks ten seconds backward. - - -* Using libtag for reading tags -=============================== - -There is a way to read tags using Libtag as your backend for -emms-info. However, since it requires a binary file (source code -provided with EMMS), it isn't enabled by default. To compile it, type -``make emms-print-metadata''. To install it, either put -emms-print-metadata in your $PATH, or add EMMS' directory to Emacs' -exec-path. Since libtag overwrites most of the usual methods for -providing info, it's best to keep it as the only function in -`emms-info-functions'. Here's a way to do so: - -(require 'emms-info-libtag) -(setq emms-info-functions '(emms-info-libtag)) - - -* EMMS, Emms, emms, or what? -============================ - -In various contexts, this program is called EMMS, Emms or emms. Those -are all correct, and which one you use is a matter of personal -preference. EMMS highlights the acronym character of the name. Emms -is akin to Emacs and Gnus, ignoring that Emms is pronounced -ee-em-em-es, and not a single name. emms is highlighting that emms is -a case-sensitive file name and Emacs Lisp command. - - -* Getting help -============== - -Emms has a mailing list at emms-help@gnu.org. To subscribe to it, -visit http://lists.gnu.org/mailman/listinfo/emms-help. If you are -familiar with the Gmane service, there is a Gmane newsgroup which -mirrors this mailing address at gmane.emacs.emms.user. - - Emms also has a website at <http://www.gnu.org/software/emms/>. - - -* License -========= - -EMMS is available under the terms of the GNU General Public License. -Please see the file COPYING for details. +Please read the fine manual which is available in the doc +directory. We do our best to make sure that it's up to date and +informative. |
