.SH SYNOPSIS
.B http-music play
[opts...]

.SH DESCRIPTION
Plays audio referenced from a playlist file.
Tracks selected using a "picker" (see \fB--picker\fR) and retrieved using a "downloader" (see \fB--downloader\fR).
Downloaded tracks are played with either the \fBmpv\fR (default) or \fBplay\fR (from SoX) command.


.SH KEYBOARD CONTROLS

.SH OPTIONS
.TP
.BR \-c ", " \-\-clear
Clears the active playlist.
This does not effect the source playlist, so specific groups can be selected using \fB\-\-keep\fR.

.TP
.BR \-\-disable\-playback\-status ", " \-\-hide\-playback\-status
Hides playback status (timestamps, etc).

.TP
.BR \-h ", " \-? ", " \-\-help
Presents a help message, directing the user to the \fBman\fR page.
If this is the last option used, nothing plays (see \fB\-\-play\fR).

.TP
.BR \-k ", " \-\-keep " \fIgroupPath\fR"
Keeps a group by adding it from the source playlist.
This is usually useful after clearing the active playlist (\fB\-\-clear\fR); it can also be used to keep a sub-group after removing an entire parent group, e.g. \fB-r foo -k foo/baz\fR.

.TP
.BR \-l ", " \-\-list\-groups ", " \-\-list
Lists all groups (but not tracks) in the (active) playlist.
If this is the last option used, nothing plays (see \fB\-\-play\fR).

.TP
.BR \-L ", " \-\-list\-all ", " \-\-list\-tracks
Lists all groups and tracks in the (active) playlist.
If this is the last option used, nothing plays (see \fB\-\-play\fR).

.TP
.BR \-\-loop\-mode ", " \-\-loop
Sets the mode by which the playback order list is looped (typically, what happens when the picker's index counter gets to the end of the list).
Valid options include \fBno-loop\fR (or \fBno\fR), \fBloop-same-order\fR (or \fBloop\fR), and \fBloop-regenerate\fR (the default).
See also \fB\-\-sort\-mode\fR.

.TP
.BR \-np ", " \-\-no\-play
Forces the playlist not to play.
See also \fB\-\-play\fR.

.TP
.BR \-o ", " \-\-open\-playlist ", " \-\-open " \fIplaylistFile\fR"
Opens a specific file to be used as the playlist file.
(This sets the source playlist.)
The default playlist file used upon loading is \fBplaylist.json\fR (in the same directory as \fBhttp-music\fR is being run in).

.TP
.BR \-p ", " \-\-play
Forces the playlist to actually play, regardless of options such as \fB\-\-list\fR. See also \fB\-\-no\-play\fR.

.TP
.BR \-\-player " \fIplayer"
Selects the mode by which audio is played.
Valid options include "mpv" and "sox" (or "play").
Most playback controls only work with the "mpv" player, but the "sox"/"play" player is typically much more easy to (and commonly) install than "mpv".
The default is \fBmpv\fR, but \fBsox\fR will be used if mpv is not installed.

.TP
.BR \-\-print\-playlist ", " \-\-log-playlist ", " \-\-json
Prints the JSON representation of the active playlist to the console.

.TP
.BR \-r ", " \-\-remove ", " \-x " \fIgroupPath\fR"
Removes a group from the (active) playlist.

.TP
.BR \-\-sort\-mode ", " \-\-sort
Sets the mode by which the playback order list is sorted.
Valid options include \fBorder\fR, \fBshuffle\fR (the default), and \fBshuffle-groups\fR.
See also \fB\-\-loop\-mode\fR.

.TP
.BR \-w ", " \-\-write\-playlist ", " \-\-write ", " \-\-save " \fIfilePath\fR"
Writes the active playlist to a file.
This file can later be used with \fB\-\-open\fR; you won't need to stick in all the filtering options again.
