# amused

amused is a music player.  It doesn't have any amazing features
built-in, on the contrary: it's quite minimal (a fancy word to say
that does very little.)  It composes well, or aims to do so, with
other tools thought.

The main feature is that audio decoding runs in a sandboxed process
under `pledge("stdio recvfd audio")` (on OpenBSD at least.)

It's available on the OpenBSD port tree starting with 7.1


## Building

The dependencies are:

 - flac
 - libmpg123
 - libvorbis
 - opusfile
 - libsndio

Then, to build:

	$ ./configure
	$ make
	# make install # eventually

The build can be customized by passing arguments to the configure
script or by using a `configure.local` file; see `./configure -h`
and [`configure.local.example`](configure.local.example) for more
information.

For each library the `configure` script first tries to see if they're
available without any extra flags, then tries again with some
hard-coded flags (e.g. `-lflac` for flac) and finally resorts to
pkg-config if available.  pkg-config auto-detection can be disable by
passing `PKG_CONFIG=false` (or the empty string)

For Linux users with libbsd installed, the configure script can be
instructed to use libbsd exclusively as follows:

	CFLAGS="$(pkg-config --cflags libbsd-overlay)" \
		./configure LDFLAGS="$(pkg-config --libs libbsd-overlay)"


## Usage

The fine man page has all nitty gritty details, but the TL;DR is

 - enqueue music with `amused add files...`
 - control the playback with `amused play|pause|toggle|stop` etc

amused tries to be usable in composition with other more familiar tools
instead of providing everything itself.  For instance, there isn't a
command to remove an item from the playlist, or shuffle it; instead,
standard UNIX tools can be used:

	$ amused show | grep -vi kobayashi | amused load
	$ amused show | sort -R | amused load
	$ amused show | sort | uniq | amused load

It also doesn't provide any means to manage a music collection.  It
plays nice with find(1) however:

	find . | amused load
