## Usage
|
|
|
|
[Read here.](https://github.com/lcpz/lain/wiki/Widgets#usage)
|
|
|
|
### Description
|
|
|
|
Shows ALSA volume with a progressbar; provides tooltips and notifications.
|
|
|
|
```lua
|
|
local volume = lain.widget.alsabar()
|
|
```
|
|
|
|
## Input table
|
|
|
|
Variable | Meaning | Type | Default
|
|
--- | --- | --- | ---
|
|
`timeout` | Refresh timeout (in seconds) | integer | 5
|
|
`settings` | User settings | function | empty function
|
|
`width` | Bar width | number | 63
|
|
`height` | Bar height | number | 1
|
|
`margins` | Bar margins | number | 1
|
|
`paddings` | Bar paddings | number | 1
|
|
`ticks` | Set bar ticks on | boolean | false
|
|
`ticks_size` | Ticks size | integer | 7
|
|
`cmd` | ALSA mixer command | string | "amixer"
|
|
`channel` | Mixer channel | string | "Master"
|
|
`togglechannel` | Toggle channel | string | `nil`
|
|
`colors` | Bar colors | table | see [Default colors](https://github.com/lcpz/lain/wiki/alsabar#default-colors)
|
|
`notification_preset` | Notification preset | table | See [default `notification_preset`](https://github.com/lcpz/lain/wiki/alsabar#default-notification_preset)
|
|
`followtag` | Display the notification on currently focused screen | boolean | false
|
|
|
|
`cmd` is useful if you need to pass additional arguments to `amixer`. For instance, you may want to define `cmd = "amixer -c X"` in order to set amixer with card `X`.
|
|
|
|
In case mute toggling can't be mapped to master channel (this happens, for instance, when you are using an HDMI output), define `togglechannel` as your S/PDIF device. Read [`alsa`](https://github.com/lcpz/lain/wiki/alsa#toggle-channel) page to know how.
|
|
|
|
`settings` can use the following variables:
|
|
|
|
Variable | Meaning | Type | Values
|
|
--- | --- | --- | ---
|
|
`volume_now.level` | Volume level | integer | 0-100
|
|
`volume_now.status` | Device status | string | "on", "off"
|
|
|
|
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.
|
|
|
|

|
|
awful.button({}, 1, function() -- left click

awful.spawn(string.format("%s -e alsamixer", terminal))
|
|
end),
|
|
awful.button({}, 2, function() -- middle click
|
|
os.execute(string.format("%s set %s 100%%", volume.cmd, volume.channel))
|
|
volume.update()
|
|
end),
|
|
awful.button({}, 3, function() -- right click
|
|
os.execute(string.format("%s set %s toggle", volume.cmd, volume.togglechannel or volume.channel))
|
|
volume.update()
|
|
end),
|
|
awful.button({}, 4, function() -- scroll up
|
|
os.execute(string.format("%s set %s 1%%+", volume.cmd, volume.channel))
|
|
volume.update()
|

|
|
awful.button({}, 5, function() -- scroll down

os.execute(string.format("%s set %s 1%%-", volume.cmd, volume.channel))
