SYNOPSIS

siren [-lv] [-c directory]

DESCRIPTION

siren is a text-based audio player.

The options are as follows.
-c directory
  Use directory as the configuration directory. The default is ~/.siren.
-l Log error and informational messages to a file. The file is created in the current directory and named siren-%d.log where %d is replaced with Ap s process ID.
-v Print version information and exit.

USER INTERFACE

Ap s user interface consists of three areas.

The bottom line is the status line. It is used to display error and informational messages and to enter commands and search queries.

The two lines above the status line show playback-related information, such as the currently playing track and the volume level.

The remainder of the screen is used to display a view. Only one view can be displayed at a time, but each view can be selected with the select-view command ( see COMMANDS below ) or the default key bindings.

The available views are as follows.
Library view
  The library view shows all tracks in the library. The add-path command may be used to add tracks. The library view can be displayed by pressing the 1 key.
Playlist view
  The playlist view shows the playlist loaded with the load-playlist command. It can be displayed by pressing the 2 key.
Browser view
  The browser view shows the contents of a directory. By default only directories and supported audio files are shown. The browser view can be used to browse through the file system and play back audio files or add them to the library or queue. The browser view can be displayed by pressing the 3 key.
Queue view
  The queue view shows all tracks that have been added to the queue. Tracks in the queue will be played back before those in other views. A track will be removed from the queue as soon as it is being played back. The queue view can be displayed by pressing the 4 key.

The playback source is the view that provides the tracks for playback. The library, playlist and browser views each can act as a playback source. A view implicitly becomes the playback source whenever a track from that view is selected for playback.

KEY BINDINGS

siren supports configurable key bindings. Each key binding has a scope: it is either specific to one view or common to all views. Key bindings are changed with the bind-key and unbind-key commands or shown with the show-binding command.

The default key bindings are as follows.

COMMANDS

siren is controlled by issuing commands. Commands can be entered at the command prompt, bound to a key or added to the configuration file.

Commands are parsed in a way similar to most shells. A command line is delimited by a newline character or a '#' character. A '#' character introduces a comment and extends to the end of the line.

A command line is broken into separate words. A word is a sequence of characters and is delimited by one or more space or tab characters. On each word, tilde expansion and glob(3) pattern expansion is performed.

The '#', '~', '*', '?', '[', '\', '’' and '' characters and the space and tab characters are special characters. A special character can be escaped by prepending it with a '\' character or by enclosing it by matching '’' or '' characters.

The following commands are available.
activate-entry
  Activate the selected entry in the current view. In the library and playlist views, an activated entry is played back. In the browser view, if the activated entry is a directory, it is entered. Otherwise, if it is a file, it is played back. In the queue view, an activated entry is played back and removed from the queue.
add-entry [-l-| -q ]
  Add the selected entry to the library or the queue. The options are as follows.

-l Add the selected entry to the library. This is the default.
-q Add the selected entry to the queue.
add-path [-l-| -q ] path ...
  Add an audio file or a directory to the library or the queue. The options are as follows.

-l Add path to the library.
-q Add path to the queue.

The default is to add path to the current view. If path is a directory, then all audio files in it are added.
bind-key scope key command
  Bind a key to a command.

The scope argument specifies the scope of the key binding. It should be one of browser, library, playlist, queue or common.

A key binding is first looked up in the scope of the current view. If no key binding is found in that scope, then it is looked up in the common scope.

The key argument specifies the key to bind. The following three types of keys can be bound.

The printable ASCII characters: these are the ASCII character codes between 32 and 126 decimal. They are represented by themselves.
The ASCII control characters: these are the ASCII character codes between 0 and 31 decimal. They are specified in case-insensitive caret notation. For example, ^A and ^a both denote the second control character.
The following case-insensitive key-names are recognised: backspace, backtab, delete, down, end, enter, escape, home, insert, left, page-down, page-up, right, space, tab, up and f1 to f20.

The command argument can be any command listed in this section.
cd [directory] Change the current working directory to directory and open it in the browser view. If directory is not specified, the user’s home directory is used instead.
command-prompt Enter the command prompt. The command prompt can be used to enter and execute commands.
delete-entry [-a] Delete the selected entry in the current view. This command is supported in the library and queue views only. The options are as follows.

-a Delete all entries in the current view.
load-playlist file
  Load the playlist file into the playlist view. Each line of file should contain the path to a track. Empty lines and lines starting with the '#' character are ignored.
move-entry-down
  Move the selected entry after its succeeding entry. This command is supported in the queue view only.
move-entry-up
  Move the entry before its preceding entry. This command is supported in the queue view only.
pause Pause or resume playback.
play Start, restart or resume playback.
play-next
  Play the next track in the playback source.
play-prev
  Play the previous track in the playback source.
quit Quit siren.
refresh-screen
  Refresh the screen.
reread-directory
  Reread the current directory in the browser view.
save-library
  Save the library to disk. The library is automatically saved when siren quits.
save-metadata
  Save the metadata cache to disk. The metadata cache is automatically saved when siren quits.
scroll-down [-h-| -l -| -p ]
  Scroll down in the current view. The options are as follows.

-h Scroll half a page.
-l Scroll one line. This is the default.
-p Scroll one page.
scroll-up [-h-| -l -| -p ]
  Scroll up in the current view. The options are analogous to those of the scroll-down command.
search-next
  Search for the next occurrence of the text earlier specified with the search-prompt command.
search-prev
  Search for the previous occurrence of the text earlier specified with the search-prompt command.
search-prompt [-b]
  Enter the search prompt. The search prompt can be used to search in the current view. The options are as follows.

-b Search backward. The default is to search forward.
seek [-b-| -f ] [[hours:minutes :seconds]]
  Seek to the specified position in the currently playing track. The options are as follows.

-b Seek backward by subtracting the specified position from the current position.
-f Seek forward by adding the specified position to the current position.
select-active-entry
  Select the active entry in the current view.
select-first-entry
  Select the first entry in the current view.
select-last-entry
  Select the last entry in the current view.
select-next-entry
  Select the next entry in the current view.
select-prev-entry
  Select the previous entry in the current view.
select-view name
  Select a view. The name argument must be one of browser, library, playlist or queue.
set option [value]
  Set option to value. If option is a Boolean value and value is not specified, it is toggled. See OPTIONS below for a list of available options.
set-volume [-d-| -i ] level
  Set the volume level. The level argument should be an integer value between 0 and 100. The options are as follows.

-d Decrease the volume level by subtracting level.
-i Increase the volume level by adding level.

Not all output plug-ins have volume support.

When using the oss output plug-in on FreeBSD, the volume level may be reset every time a track is played back. To preserve the volume level, set the hw.snd.vpc_autoreset sysctl(8) variable to 0. See sound(4) for more information.
show-binding scope key
  Show the command bound to key. The scope and key arguments are analogous to those of the bind-key command.
show-option option
  Show the value of option.
source file
  Execute the commands in file.
stop Stop playback.
unbind-key scope key
  Unbind key. The scope and key arguments are analogous to those of the bind-key command.
update-metadata [-d]
  Update the metadata cache. The options are as follows.

-d Delete the metadata of tracks that cannot be found on the file system.

OPTIONS

The appearance and behaviour of siren may be modified by changing the value of various options. Options are changed with the set command or shown with the show-option command.

There are six types of options. They are as follows.
Attribute options
  Attribute options control the character attributes of a user-interface element. Valid values are blink, bold, dim, normal, reverse, standout and underline. Two or more attributes can be specified by separating them by a comma.
Colour options
  Colour options control the foreground and background colour of a user-interface element. Valid values are black, blue, cyan, green, magenta, red, white, yellow, default and colour0 to colourN where N + 1 is the number of colours supported by the terminal.

If supported by the terminal, the colour default corresponds to the terminal’s original background or foreground colour. Otherwise, default is equivalent to black when used as a background colour and to white when used as a foreground colour.

Boolean options
  Valid values of Boolean options are true and false. As a convenience, the values on, off, yes, no, 1 and 0 are accepted as well.
Number options
  Valid values of number options are non-negative integers. The maximum value is option-specific.
String options
  Valid values of string options are option-specific.
Format-string options
  Format-string options control the formatting of information displayed on the screen. The syntax is reminiscent of that of the printf(3) family of functions.

A format string consists of ordinary characters, which are displayed unchanged, and format fields, which specify how a variable is to be displayed. A format field is introduced by the '%' character. Then, the following appears in sequence.

An optional '-' character to specify that the variable is to be left-aligned within the field. The default is to right-align.
An optional '0' character to specify that the variable is to be padded with leading zeroes. The default is to pad with space characters. This flag is ignored if the variable is to be left-aligned.
An optional sequence of numeric characters to specify the field width. If the '*' character is specified, the width is variable and will be so long as possible. If there are two or more fields with a variable width, the available space will be divided equally between them.
The name of the variable to display, enclosed by braces ( i.e. the '{' and '}' characters ). Some variables also have a one-character alias. If this alias is specified, the braces may be omitted. Which variables are available is dependent on the option.

Conditional fields are also supported. A conditional field is enclosed in braces and begins with a '?' character, followed by the name of the variable and two comma-separated fields. If the variable is a non-zero number or a non-empty string, the first value is displayed; otherwise, the second value. For example, '%{?artist,yes,no}' displays 'yes' if artist is a non-empty string and 'no' otherwise.

A literal '%' character is displayed by specifying '%%' in the format string.
