## Input table
|
|
|
|
Variable | Meaning | Type | Default
|
|
--- | --- | --- | ---
|
|
`timeout` | Refresh timeout (in seconds) | integer | 1
|
|
`music_dir` | Music directory | string | "~/Music"
|
|
`cover_size` | Album art notification size (both height and width) | integer | 100
|
|
`cover_pattern` | Pattern for the album art file | string | `*\\.(jpg|jpeg|png|gif)`*
|
|
`default_art` | Default art | string | ""
|
|
`followtag` | Display the notification on currently focused screen | boolean | false
|
|
`settings` | User settings | function | empty function
|
|
|
|
\* In Lua, "\\\\" means "\" escaped.
|
|
|
|
Default `cover_pattern` definition will made the widget set the first jpg, jpeg, png or gif file found in the directory as the album art.
|
|
|
|
Pay attention to case sensitivity when defining `music_dir`.
|
|
|
|
`settings` can use `moc_now` table, which contains the following string values:
|
|
|
|
- state (possible values: "PLAY", "PAUSE", "STOP")
|
|
- file
|
|
- artist
|
|
- title
|
|
- album
|
|
- elapsed (Time elapsed for the current track)
|
|
- total (The current track's total time)
|
|
|
|
and can modify `moc_notification_preset` table, which will be the preset for the naughty notifications. Check [here](https://awesomewm.org/apidoc/libraries/naughty.html#notify) for the list of variables it can contain. Default definition:
|
|
|
|
```lua
|
|
moc_notification_preset = {
|
|
title = "Now playing",
|
|
timeout = 6,
|
|
text = string.format("%s (%s) - %s\n%s", moc_now.artist,
|
|
moc_now.album, moc_now.elapsed, moc_now.title)
|
|
}
|
|
```
|
|
|
|
With multiple screens, the default behaviour is to show a visual notification pop-up window on the first screen. By setting `followtag` to `true` it will be shown on the currently focused tag screen.
|
|
|
|
## Output table
|
|
|
|
Variable | Meaning | Type
|
|
--- | --- | ---
|
|
`widget` | The widget | `wibox.widget.textbox`
|
|
`update` | Update `widget` | function
|
|
`timer` | The widget timer | [`gears.timer`](https://awesomewm.org/doc/api/classes/gears.timer.html)
|
|
|
|
The `update` function can be used to refresh the widget before `timeout` expires.
|
|
|
|
You can use `timer` to start/stop the widget as you like.
|
|
|
|
## Keybindings
|
|
|
|
You can control the widget with key bindings like these:
|
|
|
|
```lua
|
|
-- MOC control
|
|
awful.key({ altkey, "Control" }, "Up",
|
|
function ()
|
|
os.execute("mocp -G") -- toggle
|
|
moc.update()
|
|
end),
|
|
awful.key({ altkey, "Control" }, "Down",
|
|
function ()
|
|
os.execute("mocp -s") -- stop
|
|
moc.update()
|
|
end),
|
|
awful.key({ altkey, "Control" }, "Left",
|
|
function ()
|
|
os.execute("mocp -r") -- previous
|
|
moc.update()
|
|
end),
|
|
awful.key({ altkey, "Control" }, "Right",
|
|
function ()
|
|
os.execute("mocp -f") -- next
|
|
moc.update()
|
|
end),
|
|
```
|
|
|
|
where `altkey = "Mod1"`.
|
|
|
|
If you don't use the widget for long periods and wish to spare CPU, you can toggle it with a keybinding like this:
|
|
|
|
```lua
|
|
-- toggle MOC widget
|
|
awful.key({ altkey }, "0",
|
|
function ()
|
|
local common = { text = "MOC widget ", position = "top_middle", timeout = 2 }
|
|
if moc.timer.started then
|
|
moc.timer:stop()
|
|
common.text = common.text .. markup.bold("OFF")
|
|
else
|
|
moc.timer:start()
|
|
common.text = common.text .. markup.bold("ON")
|
|
end
|
|
naughty.notify(common)
|
|
end),
|
|
```
