Shows MPD status in a textbox.
mpdwidget = lain.widgets.mpd()
Now playing songs are notified like this:
+--------------------------------------------------------+
| +-------+ |
| |/^\_/^\| Now playing |
| |\ O O /| Cannibal Corpse (Hammer Smashed Face) - 1993 |
| | '.o.' | Hammer Smashed Face (Radio Disney Version) |
| +-------+ |
+--------------------------------------------------------+
You need a file like this
(Front|front|Cover|cover|Art|art|Folder|folder)\.(jpg|jpeg|png|gif)
in the album folder in order to show album art too.
**Note:** if MPD is turned off or not set correctly, the widget will constantly display "N/A N/A".
### input table
Variable | Meaning | Type | Default
--- | --- | --- | ---
`timeout` | Refresh timeout seconds | int | 2
`password` | MPD password | string | ""
`host` | MPD server | string | "127.0.0.1"
`port` | MPD port | string | "6600"
`music_dir` | Music directory | string | "~/Music"
`cover_size` | Album art notification size | int | 100
`default_art` | Default art | string | ""
`followmouse` | Notification behaviour | boolean | false
`echo_cmd` | custom call for `echo`* | string | "echo"
`settings` | User settings | function | empty function
\* `echo` implementation is shell dependent, you may need to set this variable properly (`echo -e` [for instance](https://github.com/copycat-killer/lain/issues/112)) in order for the widget to fetch the data correctly.
Pay attention to case sensitivity when defining `music_dir`.
`settings` can use `mpd_now` table, which contains the following string values:
- state (possible values: "play", "pause", "stop")
- file
- artist
- title
- album
- date
- [time](https://github.com/copycat-killer/lain/pull/90)
- [elapsed](https://github.com/copycat-killer/lain/pull/90) (seconds)
and can modify `mpd_notification_preset` table, which will be the preset for the naughty notifications. Check [here](http://awesome.naquadah.org/doc/api/modules/naughty.html#notify) for the list of variables it can contain. Default definition:
mpd_notification_preset = {
title = "Now playing",
timeout = 6,
text = string.format("%s (%s) - %s\n%s", mpd_now.artist,
mpd_now.album, mpd_now.date, mpd_now.title)
}
In multiple screen setups, the default behaviour is to show a visual notification pop-up window on the first screen. By setting `followmouse` to `true` it will be shown on the current mouse screen.
### output table
Variable | Meaning | Type
--- | --- | ---
`widget` | The textbox | `wibox.widget.textbox`
`update` | The notification | function
You can control the widget with key bindings like these:
-- MPD control
awful.key({ altkey, "Control" }, "Up",
function ()
awful.util.spawn_with_shell("mpc toggle || ncmpcpp toggle || ncmpc toggle || pms toggle")
mpdwidget.update()
end),
awful.key({ altkey, "Control" }, "Down",
function ()
awful.util.spawn_with_shell("mpc stop || ncmpcpp stop || ncmpc stop || pms stop")
mpdwidget.update()
end),
awful.key({ altkey, "Control" }, "Left",
function ()
awful.util.spawn_with_shell("mpc prev || ncmpcpp prev || ncmpc prev || pms prev")
mpdwidget.update()
end),
awful.key({ altkey, "Control" }, "Right",
function ()
awful.util.spawn_with_shell("mpc next || ncmpcpp next || ncmpc next || pms next")
mpdwidget.update()
end),
where `altkey = "Mod1"`.
