NAME
Shell.FM - Lightweight, console-based player for Last.FM radio streams.

SYNOPSIS
shell-fm [-d] [-i address] [-p port] [-b] [-D device] [-y proxy] [-h] lastfm://...

DESCRIPTION
Shell.FM is a lightweight, console-based player for radio streams provided by Last.FM.

OPTIONS

-d  Fork to background (requires a socket interface to be set up so it can still be controlled somehow).

-i <address>
    Enable the socket interface and bind it to the given host address (should be the host name or IP address of the host shell-fm is running on).

-p <port>
    Make the socket interface listen for incoming connections on the given port. Default is 54311.

-b  Enable batch mode (some freaky mode that makes shell-fm easier to handle from inside emacs). This was not my idea.

-D <device>
    Use the given device file as audio device. This is only used if libao support is disabled. Default is /dev/audio.

-y <proxy>
    Make shell-fm use the given host as proxy server for HTTP requests.

-h  Print help text and exit.

lastfm://...
    URI of a Last.FM radio stream to play after startup. For example: `shell-fm -d lastfm://artist/The%20Beatles/similarartists'

USAGE
On startup, shell-fm will ask you for your Last.FM login and password (if not provided in your ~/.shell-fm/shell-fm.rc). If you've given a stream URI on the command line or there is a default radio defined in the configuration file, shell-fm will now try to play it. When the startup is done, there are lots of keys to control shell-fm. Here is a alphabetically sorted list.

a   Add the currently played track to your Last.FM playlist.

A   Ban the artist of the currently played track. Whenever a track of that artist is played from now on, it is automatically banned.

B   Ban the currently played track.

d   Enabled/disable discovery mode. I'm not sure if this has any effect, and it looks like even the Last.FM guys don't really know what it does, but I think it is meant to ensure that you get only tracks that you don't know yet.

f   Jump to the fan radio station of the artist of the currently played track.

h   List bookmarks.

H   Bookmark the currently played radio station. You'll be asked to hit a digit key. Whenever you hit that key again from now on, shell-fm will jump to that radio station.

i   Print some more information about the currently played track.

l   Love the currently played track.

n   Skip the currently played track.

p   Pause. If you pause too long, the stream will break, which has the same effect as stopping the stream (see below).

P   Enable/disable reporting played tracks to your Last.FM profile. Enabled by default.

Q   Quit.

r   Change radio station. This will prompt you for an Last.FM radio station URI. The tabulator key helps if you don't know what to type. Arrow-Up and Arrow-Down allow you to browse your radio history. Enter these without the "lastfm://" prefix.

    For example: `radio url> globaltags/world'

R   Recommend the currently played track/artist/album to another Last.FM user.

S   Stop playing.

s   Jump to the similar artists radio stream of the currently played tracks artist.

T   Tag the currently played track/artist/album. Tabulator key completes known tags.

+   Increase volume (vol).

*   Increase volume (pcm).

-   Decrease volume (vol).

/   Decrease volume (pcm).

SETUP
Before you start, you should have created the directories ~/.shell-fm and ~/.shell-fm/cache or you will get a lot of warnings, the tab-completion will be extremely slow and you can't make use of some features (auto-ban, history, bookmarks). You might also want to place a configuration file in ~/.shell-fm for a faster startup.

CONFIGURATION
This section describes the syntax and options for the shell-fm configuration file. The file should be placed in ~/.shell-fm/shell-fm.rc and should consist of simple key = value assignments. See (far) below for a sample configuration. These are the available options.

username = your-login
    This is your login on Last.FM. If this is provided, shell-fm won't ask you for it on startup anymore.

password = your-password
    This is your (clear text) Last.FM password. If this and your login is provided in the configuration, shell-fm won't ask you on startup.

default-radio = lastfm://...
    If this is provided (and valid), shell-fm will play this station by default after startup. If there's another station URI given on the command line, it will override this setting.

np-file = path-to-file
    If this is defined, shell-fm will print information about the currently played track into the given file, whenever a new track is played.

np-file-format = format-string
    This defines how the information written to your now-playing file will look like. There are several format flags available. Have a look at the FORMAT FLAGS section for the details.

np-cmd = shell command
    If this is defined, the given command will be execute whenever a new track starts. The value may contain format flags.

?-color = color
    This allows you to color format elements. The ? may be the letter of any format flag (without percent). The color is just a normal shell color code matching "[01];3[0-7]". Whenever the format element is printed to the console, it will have the given color. Have a look at the COLORS section for a list.

key0x?? = shell command
    This allows you to bind shell commands to free keys (keys that are not used by shell-fm, check the USAGE section above for a list). ?? should be the hex code of the ASCII code of the key. The command you assign will be evaluated (check the FORMAT FLAGS section) and executed then. This "feature" allows you to implement own features, like fetching and printing the lyrics of the currently played track, etc. If you have a cool idea or even a working script, I'd be happy if you let me know.

bind = host
    This specifies the network interface you want shell-fm to bind to. host should be the host name or an IP address of host shell-fm is running on. shell-fm will open a port (see the port option below) on the specified interface which you can connect to to control shell-fm remotely (or from local scripts, see key0x?? above). Check the NETWORK INTERFACE COMMANDS section below for a list of known commands.

port = port-number
    With this option you can change the port shell-fm will listen on (if bind is specified). Default is 54311.

extern = shell command
    This allows you to specify an external program or script as player for the streams. If given, shell-fm will run the command and pipe the MP3 stream into it, instead of playing the stream itself. For example, extern = madplay -Q - works very fine. This option is meant as a work-around for architectures that shell-fm doesn't work completly profectly on.

proxy = proxy server
    This allows you to specify a proxy server for the HTTP requests.

expiry = some-number
    This defines the number of seconds until a cached page expires. The default is 86400 seconds (24 hours). You shouldn't set a very low value here, since the Last.FM server often are very slow. This mostly affects the prompts (radio prompt, tag prompt, ...), since shell-fm fetches some feeds to get values for the tab-completion.

device = path
    Path to the audio device to use (see -D command line option).

title-format = format-string
    This is the format of the track string that is printed to the console for every track played. Default is 'Now playing "%t" by %a.'.

minimum = percentage
    With this option you can change the minimum duration a track must have been played to be scrobbled (in percent, but without the % sign). For example, if this option is set to 75, the track will not be scrobbled if it has not been played for at least 75% of its total duration. If you skip or stop the track before it has been played for 75%, it will not be scrobbled. Default is 50%, as specified in the scrobbling protocol version 1.2.

delay-change = something
    If this is set to anything, and you change the station with 'r', 's' or 'f', the station-change will be delayed until the currently played track finishes or is skipped.

FORMAT FLAGS
There are several format flags allowed for some options. Here is the list.

%a  Artist name.

%t  Track title.

%l  Album name.

%d  Track duration in seconds.

%s  Station name.

%S  Station URL.

%A  URL of the artists page on Last.FM.

%L  URL of the albums page on Last.FM.

%T  URL of the tracks page on Last.FM.

%R  Remaining seconds of the played track.

NETWORK INTERFACE COMMANDS
This section describes the commands shell-fm's network interface knows. To use the interface, you must provide a valid value to the bind option in your configuration or use the -i option on the command line. Then you can connect the specified port (54311 by default) and send one command at a time. You also have to hurry, since there is a very short timeout. Best thing would be if you used a script for accessing this interface. (See shell-fm-*/scripts/ for examples) This is a list of the known commands.
