134.134.137.71: /* Configuration */

'''Smex is a M-x enhancement''' for Emacs. Built on top of [[Ido]], it provides a convenient interface to your recently and most frequently used commands. And to all the other commands, too.

= Installation =

Download via [[package.el]], [[el-get]] or [http://github.com/nonsequitur/smex/blob/master/smex.el?raw=true the sources] and set-up your load-path.

You are now ready to call {{Command|smex}}. The commands are displayed in an Ido completion buffer, ordered by relevance. The 7 most recently executed commands come first, the rest are sorted by frequency of use, command length and in alphabetical order.

= Configuration =

To auto-start Smex every time you open Emacs add these lines to your .emacs file:
<source lang="lisp">
(require 'smex) ; Not needed if you use package.el
(smex-initialize) ; Can be omitted. This might cause a (minimal) delay
; when Smex is auto-initialized on its first run.
</source>

Bind some keys:
<source lang="lisp">
(global-set-key (kbd "M-x") 'smex) ;overrides M-x aka execute-extended-command
(global-set-key (kbd "M-X") 'smex-major-mode-commands)
;; This is your old M-x.
(global-set-key (kbd "C-c C-c M-x") 'execute-extended-command)
</source>

== Delayed Initiation ==

Use the following code to make emacs startup a little faster. This delays initializing smex until it’s needed. Just have smex call ‘smex-initialize’ when it’s needed instead of having the user do it.

<source lang="lisp">
(global-set-key [(meta x)]
(lambda ()
(interactive)
(or (boundp 'smex-cache)
(smex-initialize))
(global-set-key [(meta x)] 'smex) (smex)))

(global-set-key [(shift meta x)]
(lambda () (interactive)
(or (boundp 'smex-cache) (smex-initialize))
(global-set-key [(shift meta x)] 'smex-major-mode-commands)
(smex-major-mode-commands)))

</source>

Media player

134.134.137.71: short additon.

= EMMS =

EMMS, The Emacs Multimedia System.

EMMS is the Emacs Multimedia System. It tries to be a clean and small application to play multimedia files from Emacs using external players. Many of it's ideas are derived from MpthreePlayer , but it tries to be more general and cleaner.

The fact that EMMS is based on external players makes it powerful, because it supports all formats that those players support, with no effort from your side.

== Features ==

* Free Software (as in Free Speech, and Free Beer)
* Extensible
* Very light (some might even say stealth)
* Audio support : MP3, Ogg Vorbis, FLAC
* Video support : MPEG, WMV, MOV, AVI, OGM, MKV, etc...
* Tagging capability, possibly batched
* Playlist management
* Remotely drivable via emacsclient (playlist creation via rox-filer, for example)
* And last but not least : Written in Emacs lisp :)

== Installation ==

Install the needed packages with the package manager of your system :

<source lang="bash">
sudo apt-get install emms vorbis-tools
</source>

(you may also try with [http://wikemacs.org/wiki/El-get el-get].)

add the following to your ~/.emacs :

<source lang="scheme">
(require 'emms-setup)
(emms-all)
(emms-default-players)
</source>
and, as usual, restart emacs or ''M-x eval-current-buffer RET''.

== Usage ==

You can play a file or a directory with the command ''M-x emms-play-file'' or ''emms-play-directory''.

You can add files and directories to the emms playlist (which will be created if it doesn't exist yet) with ''M-x emms-add-file'', play it with emms-start and you can '''visit the playlist buffer''' by simply calling '''M-x emms RET'''. Hitting '?' in the playlist buffer will show you all the available shortcuts.

=== Add other file extensions ===

If you want to, say, be able to '''read flv videos''' :
<source lang="scheme">
;; add flv and ogv
(define-emms-simple-player mplayer '(file url)
(regexp-opt '(".ogg" ".mp3" ".wav" ".mpg" ".mpeg" ".wmv" ".wma"
".mov" ".avi" ".divx" ".ogm" ".asf" ".mkv" "http://" "mms://"
".rm" ".rmvb" ".mp4" ".flac" ".vob" ".m4a" ".flv" ".ogv" ".pls"))
"mplayer" "-slave" "-quiet" "-really-quiet" "-fullscreen")
</source>

== Extensions ==

=== Get lyrics of current song ===

We have to install '''emms-get-lyrics.el'''.

With [[el-get]] : '''el-get-install RET emms-get-lyrics RET'''.

Or :
* save https://raw.github.com/talau/elisp/master/emms-get-lyrics.el in your ~/.emacs.d/my-extensions
* be sure you have '''emacs-w3m''' installed
* add those two lines in your ~/.emacs :
<source lang="scheme">
(add-to-list 'load-path "~/.emacs.d/my-extensions/")
(require 'emms-get-lyrics)
</source>
* {{Command|evaluate-current-buffer}}

Then start playing a song and call {{Command|emms-get-lyrics-current-song}}.

Excerpt from its documentation :
<blockquote>
The function 'emms-get-lyrics-current-song' tries to get the lyrics
of the song that emms is currently playing [from http://www.lyricwiki.org/]. It currently requires
w3m to get the lyrics. It copies the lyrics to a file ending in
.lyrics; if the variable `emms-get-lyrics-use-files' is nil, it
will just display the lyrics in a buffer without saving them to a
file. If the variable `emms-get-lyrics-dir' is non-nil, then the
lyrics will be put in this directory with the file
ARTIST-TITLE.lyrics; otherwise it will be put in the same directory
as the song file, in a file with the same name as the song file
except the extension will by ".lyrics".
</blockquote>

= Mpg123 =

'''mpg123''' is a package written by HiroseYuuji for playing .mp3 and .ogg files with the mpg123 and ogg123 programs.

== Installation ==

=== Debian system ===

Install the [http://packages.debian.org/search?keywords=mpg123-el mpg123-el package] :

<source lang="bash">
apt-get install mpg123-el
</source>

restart emacs, and you can start using it.

=== All systems ===

Install the mpg123 and ogg123 programs with your system's package manager :
<source lang="bash">
apt-get install mpg123 ogg123
</source>

Grab the sources from [http://www.gentei.org/~yuuji/software/mpg123el/ mpg123.el's git repository] and save them in ''~/.emacs.d/mpg123.el''.

Check you have the following in your ''.emacs'' :

<source lang="scheme">
(add-to-list 'load-path "~/.emacs.d/")
</source>

restart emacs or {{Command|eval-current-buffer}}.

== Usage ==

{{Command|mpg123}}
: start mpg123, choose a directory or a mp3/ogg file and start listening. The buffer shows a complete list of commands.

= Bongo =

Bongo is a beautiful, flexible and usable buffer-oriented media player for Emacs, developed in parallel to EMMS 2.0. If you store your music collection locally and use structured file names, then Bongo is a great way for you to play music from within Emacs.

Notable features of Bongo include :

* separate playlist and library buffers (each of which you may have any number — even zero of both is okay if you don’t need playlist functionality),
* hierarchical buffers with collapsable sections for each artist and album,
* familiar Emacs bindings for editing Bongo buffers (edit playlists much like you would regular text),
* a nice visual seeking interface doubling as a progress meter (hit ‘s’),
* a visual audio volume control (Volume, which is actually a stand-alone package),
* built-in support for playing and retreiving information about audio CDs,
* built-in support for submitting information to Last.fm using ‘lastfmsubmitd’,
* the ability to perform arbitrary actions (stopping playback is a simple example) once playback reaches certain points in the playlist, using so-called “action tracks”,
* an XMMS-like keymap for XMMS refugees,
* zero-configuration, out-of-the-box rock’n’roll action.

Bongo woks with many backend processes : mpg123, mplayer, vlc, ogg123, timidity and others.

== Installation ==

There is no el-get recipe for bongo (is there for MELPA in emacs24 ?). You have to install it from git. It is a 3 steps process :

* go to where you want to put the sources :
<source lang="bash">
cd ~/.emacs.d/your-extensions
</source>

* retrieve the sources :
<source lang="bash">
git clone git://github.com/dbrock/bongo.git
</source>

* Add the Bongo directory to your ‘load-path’, and then run {{Command|load-library RET bongo RET}}. Here’s what you’ll want to put in your ~/.emacs:
<source lang="scheme">
;; Change this to the correct directory name for you.
(add-to-list 'load-path "~/.emacs/your-extensions/bongo")
(autoload 'bongo "bongo"
"Start Bongo by switching to a Bongo buffer." t)
</source>

== Usage ==

Run Bongo with (have a guess) {{Command|bongo}} and you'll be left with a quite explicit buffer. To learn more commands, please notice the menu entry and see the documentation at the project's page.

<source lang="text">

[here a nice Bongo logo]

Welcome to Bongo, the buffer-oriented media player!

This is a Bongo library buffer. It's empty now, but in a
few moments it could hold your entire media collection ---
or just the parts that you are currently interested in.

To insert local media files or directories, use `i'.
To insert the URL of a media file or stream, use `I u RET'.
To insert other things, use `I TAB' to list possibilities.

To enqueue tracks in the nearest playlist buffer, use `e'.
To hop to the nearest playlist buffer, use `h'.

Enabled backends: mpg123, mplayer, ogg123
To modify this list, customize `bongo-enabled-backends'.

Bongo is free software licensed under the GNU GPL.
Report bugs to <bongo-devel@nongnu.org>.

</source>

Basically, you're going to switch between a '''library buffer''' and a '''playlist buffer'''. You have to add tracks to the library, as indicated. Then you can start playing a track (enter). This adds the track on the playlist buffer. You can switch between buffers with '''h'''.

When on the library buffer, to add a track to the end of the playlist, press '''e'''. To add it at the beginning, press '''E'''.

* Pause playback : SPC
* Stop playback : '''C-c C-s'''

== Getting further ==

Check the good documentation on the project's page :
https://github.com/dbrock/bongo

== Play radio ==

Bongo can read online streams out of the box. As said in the buffer, press '''i''' and paste your stream's url.

== Remote control ==

Use '''bongo-pause/resume''', '''bongo-next''' and '''bongo-previous''' and couple them with [http://wikemacs.org/wiki/Emacs_server EmacsServer].

<source lang="scheme">
emacsclient -e '(bongo-pause/resume)'
</source>
