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:

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: Linux (required tools: sysfs)

• Arguments:
  • takes the AC device as an argument, i.e "AC" or "ACAD"
  • the device is linked under /sys/class/power_supply/ and should have a file called "online"
• Returns
  • if AC is connected, $1 returns "On", if not it returns "Off", if AC doesn't exist, $1 is "N/A"

vicious.contrib.ati

Provides various info about ATI GPU status. Supported platforms: Linux (required tools: sysfs)

• Arguments:
  • takes card ID as an argument, i.e. "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.countfiles

vicious.contrib.dio

• provides I/O statistics for requested storage devices
• takes 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
• takes OpenWeatherMap city ID as an argument, i.e. "1275339"
• returns a table with string keys: {city}, {wind deg}, {wind aim}, {wind kmh}, {wind mps}, {sky}, {weather}, {temp c}, {humid}, {press}

vicious.contrib.nvinf

• provides GPU utilization, core temperature, clock frequency information about Nvidia GPU from nvidia-settings
• takes optional card ID as an argument, i.e. "1", or defaults to ID 0
• returns first 4 values as usage of GPU core, memory, video engine and PCIe bandwidth, 5th as temperature of requested graphics device, 6th as frequency of GPU core, 7th as memory transfer rate

vicious.contrib.nvsmi

• provides (very basic) information about Nvidia GPU status from SMI
• takes optional card ID as an argument, i.e. "1", or defaults to ID 0
• returns 1st value as 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 - takes the 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 use the command: pacmd list-sinks | grep 'name:' - returns 1st value as the volume level

• vicious.contrib.pulse.add(percent, sink)
  • @percent is a number, which increments or decrements the volume level by its value in percent
  • @sink optional, same usage as in vicious.contrib.pulse
  • returns the exit status of pacmd
• vicious.contrib.pulse.toggle(sink)
  • inverts the volume state (mute -> unmute; unmute -> mute)
  • @sink optional, same usage as in vicious.contrib.pulse
  • returns the exit status of pacmd

vicious.contrib.rss

vicious.contrib.sensors

vicious.contrib.wpa

• provides information about the wifi status
• requires 'wpa_cli' from wpa_supplicant
• takes the interface as an argument, i.e "wlan0" or "wlan1"
• returns a table with string keys: {ssid}, {qual}, {ip}, {bssid}

vicious.contrib.buildbot

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

• Returns:
  • returns build status in the format: [..]
  • if is the same as only one number is displayed
  • colors: red - failed, green - successful, yellow - in progress
  • it depends on lua json parser (e.g. liblua5.1-json on Ubuntu 12.04)

Usage examples

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

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