Contrib

Contrib libraries, or widget types, are extra snippets of code you can use. Some are for less common hardware, and other were contributed by Vicious users. The contrib directory also holds widget types that were obsoleted or rewritten. Contrib widgets will not be imported by init unless you explicitly enable it, or load them in your rc.lua.

Usage within Awesome

To use contrib widgets uncomment the line that loads them in init.lua. Or you can load them in your rc.lua after you require Vicious:

local vicious = require("vicious")
vicious.contrib = require("vicious.contrib")

Widget types

Most widget types consist of worker functions that take the format argument given to vicious.register as the first argument, warg as the second, and return a table of values to insert in the format string. But we have not insisted on this coding style in contrib. So widgets like PulseAudio have emerged that are different. These widgets could also depend on Lua libraries that are not distributed with the core Lua distribution. Ease of installation and use does not necessarily have to apply to contributed widgets.

vicious.contrib.ac

Provide status about the power supply (AC).

Supported platforms: GNU/Linux, requiring sysfs.

• Argument: the AC device, i.e "AC" or "ACAD". The device is linked under /sys/class/power_supply/ and should have a file called online.
• Returns {"On"} if AC is connected, else {"Off"}. If AC doesn't exist, returns {"N/A"}.

vicious.contrib.ati

Provides various info about ATI GPU status.

Supported platforms: GNU/Linux, requiring sysfs.

• Argument: card ID, e.g. "card0" (and where possible, uses debugfs to gather data on radeon power management)
• Returns a table with string keys: ${method}, ${dpm_state}, ${dpm_perf_level}, ${profile}, ${engine_clock mhz}, ${engine_clock khz}, ${memory_clock mhz}, ${memory_clock khz}, ${voltage v}, ${voltage mv}

vicious.contrib.batpmu

vicious.contrib.batproc

vicious.contrib.btc

Provides current Bitcoin price in any currency by code.

Platform independent, although requiring curl and either lua-cjson or luajson.

• Argument: currency code, e.g. "usd", "rub" and other. Default to "usd".
• Returns a table with string key ${price}.

vicious.contrib.buildbot

Provides last build status for configured buildbot builders (http://trac.buildbot.net/).

Supported platforms: platform independent, though requiring Lua JSON parser luajson.

Returns build status in the format: [<builderName>.<currentBuildNumber>.<lastSuccessfulBuildNumber>]. If <currentBuildNumber> is the same as <lastSuccessfulBuildNumber> only one number is displayed. <buildNumber> colors: red - failed, green - successful, yellow - in progress.

vicious.contrib.countfiles

vicious.contrib.cmus

NOTE: This widget type has been promoted to widgets.

Provides cmus player information using cmus-remote.

Supported platforms: platform independent.

• Argument: a table whose first field is the socket including host (or nil).
• Returns a table with string keys: ${status}, ${artist}, ${title}, ${duration}, ${file}, ${continue}, ${shuffle}, ${repeat}.

vicious.contrib.dio

Provides I/O statistics for requested storage devices.

• Argument: the disk as an argument, i.e. "sda", or a specific partition, i.e. "sda/sda2"
• Returns a table with string keys: ${total_s}, ${total_kb}, ${total_mb}, ${read_s}, ${read_kb}, ${read_mb}, ${write_s}, ${write_kb}, ${write_mb} and ${sched}

vicious.contrib.mpc

vicious.contrib.netcfg

vicious.contrib.net

vicious.contrib.openweather

Provides weather information for a requested city

• Argument: OpenWeatherMap city ID, e.g. "1275339"
• Returns a table with string keys: ${city}, ${wind deg}, ${wind aim}, ${wind kmh}, ${wind mps}, ${sky}, ${weather}, ${temp c}, ${humid} and ${press}

vicious.contrib.nvinf

Provides GPU utilization, core temperature, clock frequency information about Nvidia GPU from nvidia-settings

Supported Platforms: platform independent

• Argument (optional): card ID as an argument, e.g. "1", default to ID 0
• Returns an array containing:
  • $1: Usage of GPU core
  • $2: Usage of GPU memory
  • $3: Usage of video engine
  • $4: Usage of PCIe bandwidth
  • $5: Uemperature of requested graphics device
  • $6: Urequency of GPU core
  • $7: Uemory transfer rate

vicious.contrib.nvsmi

Provides (very basic) information about Nvidia GPU status from SMI

Supported platforms: platform independent

• Argument (optional): card ID as an argument, e.g. "1", default to ID 0
• Returns an array containing temperature of requested graphics device

vicious.contrib.ossvol

vicious.contrib.pop

vicious.contrib.pulse

Provides volume levels of requested pulseaudio sinks and functions to manipulate them

• Argument (optional): name of a sink as an optional argument. A number will be interpret as an index, if no argument is given, it will take the first-best. To get a list of available sinks run pacmd list-sinks | grep 'name:'.
• Returns an array whose only element is the volume level

vicious.contrib.pulse.add(percent[, sink])

• percent is the percentage to increment or decrement the volume from its current value
• Returns the exit status of pacmd

vicious.contrib.pulse.toggle([sink])

• Toggles mute state
• Returns the exit status of pacmd

vicious.contrib.rss

vicious.contrib.sensors

vicious.contrib.wpa

Provides information about the wifi status.

Supported Platforms: platform independent, requiring wpa_cli.

• Argument: the interface, e.g. "wlan0" or "wlan1"
• Returns a table with string keys: ${ssid}, ${qual}, ${ip}, ${bssid}

Usage examples

Pulse Audio widget:

vol = wibox.widget.textbox()
local sink = "alsa_output.pci-0000_00_1b.0.analog-stereo"
vicious.register(vol, vicious.contrib.pulse, " $1%", 2, sink)
vol:buttons(awful.util.table.join(
    awful.button({}, 1, function () awful.util.spawn("pavucontrol") end),
    awful.button({}, 4, function () vicious.contrib.pulse.add(5, sink) end),
    awful.button({}, 5, function () vicious.contrib.pulse.add(-5, sink) end)))

Buildbot widget

buildbotwidget = wibox.widget.textbox()
vicious.register(
    buildbotwidget, vicious.contrib.buildbot, "$1,", 3600,
    {{builder="coverage", url="http://buildbot.buildbot.net"},
     {builder="tarball-slave", url="http://buildbot.buildbot.net"}})
