SYNOPSIS

liquidsoap [options] [script|expression]

DESCRIPTION

Liquidsoap is a programming language for describing multimedia streaming systems. It is very flexible, making simple things simple but giving a lot of control for advanced uses. Liquidsoap supports audio, video and MIDI streams, and a wide range of input/output operators including Icecast and various soundcard APIs. It can perform a broad range of signal processing, combine streams in various ways, support custom transitions, generate sound procedurally... and all this can be assembled as you wish. Input files can be accessed remotely, or even be synthesized on the fly using external scripts such as speech synthesis. Finally, interaction with a running liquidsoap instance is possible via telnet or socket.

Liquidsoap scripts passed on the command line will be evaluated: they shall be used to define the streaming system to be ran. It is possible to pass multiple scripts; they will all be ran successively, and definitions from one script can be used in subsequent ones. A script will be read from standard input if - is given as script filename. Information about scripting liquidsoap is available on our website: http://liquidsoap.fm/

If the parameter is not a file it will be treated as an expression which will be executed. It is a convenient way to test simple one-line scripts. When running only one-liners, the default is to log messages directly on stdout rather than to a file.

OPTIONS

-

 Read script from standard input.

--

Stop parsing the command-line and pass subsequent items to the script.

--debug

Print debugging log messages.

--dynamic-plugins-dir path

Directory where to look for plugins.

--errors-as-warnings

Issue warnings instead of fatal errors for unused variables and ignored expressions. If you are not sure about it, it is better to not use it.

--interactive

Start an interactive interpreter.

--list-plugins

List all plugins (builtin scripting values, supported formats and protocols).

--list-plugins-xml

List all plugins (builtin scripting values, supported formats and protocols), output as XML.

--no-pervasives

Do not load pervasive script libraries.

--version

Display liquidsoap's version.

-c, --check

Check and evaluate scripts but do not perform any streaming.

-cl, --check-lib

Like --check but treats all scripts and expressions as libraries, so that unused toplevel variables are not reported.

-d, --daemon

Run in daemon mode.

-f, --force-start

For advanced dynamic uses: force liquidsoap to start even when no active source is initially defined.

-h plugin

Print the description of a plugin, eg. a builtin scripting function.

-i

Display inferred types.

-p, --parse-only

Parse scripts but do not type-check and run them.

-q, --quiet

Do not print log messages on standard output.

-r filename

Process a request.

-T, --disable-telnet

Disable the telnet server.

-U, --disable-unix-socket

Disable the unix socket.

-t, --enable-telnet

Enable the telnet server.

-u, --enable-unix-socket

Enable the unix socket.

-v, --verbose

Print log messages on standard output.

--conf-descr-key key

Describe a configuration key.

--conf-descr

Show all configuration keys with their documentation.

--conf-descr-liqi

Show all configuration keys with their documentation in liqi (documentation wiki) format.

--conf-dump

Dump the configuration state

-help, --help
