Contrib Widget Types ==================== Contrib libraries, or widget types, are extra snippets of code you can use. Some are for less common hardware, and others 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: .. code-block:: lua 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 :lua:func:`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](https://en.wikipedia.org/wiki/ISO_4217). Platform independent, although requiring ``curl`` and either [lua-cjson](https://github.com/mpx/lua-cjson/) or [luajson](https://github.com/harningt/luajson/). * Argument: currency code, e.g. ``"usd"``, ``"rub"`` and other. Default to ``"usd"``. * Returns a table with string key ``${price}``. vicious.contrib.buildbot ^^^^^^^^^^^^^^^^^^^^^^^^ Provides last build status for configured buildbot builders (http://trac.buildbot.net/). Supported platforms: platform independent, though requiring Lua JSON parser [luajson](https://github.com/harningt/luajson/). Returns build status in the format: ``[..]``. If ```` is the same as ```` only one number is displayed. ```` colors: red---failed, green---successful, yellow---in progress. vicious.contrib.countfiles ^^^^^^^^^^^^^^^^^^^^^^^^^^ vicious.contrib.cmus ^^^^^^^^^^^^^^^^^^^^ .. note:: This widget type has been promoted to :ref:`widgets`. Provides cmus player information using ``cmus-remote``. Supported platforms: platform independent. * Argument: a table whose first field is the socket including host (or nil). * Returns a table with string keys: ``${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 ``${sched}`` vicious.contrib.mpc ^^^^^^^^^^^^^^^^^^^ vicious.contrib.netcfg ^^^^^^^^^^^^^^^^^^^^^^ vicious.contrib.net ^^^^^^^^^^^^^^^^^^^ vicious.contrib.openweather ^^^^^^^^^^^^^^^^^^^^^^^^^^^ Provides weather information for a requested city from OpenWeatherMap (OWM) * Argument: a table containing the fields ``city_id`` with the OWM city ID, e.g. ``"2643743"`` and ``app_id`` with the the OWM app ID, e.g ``"4c57f0c88d9844630327623633ce269cf826ab99"`` * Returns a table with string keys: ``${city}``, ``${humid}``, ``${press}``, ``${sky}``, ``${sunrise}``, ``${sunset}``, ``${temp c}``, ``${temp max c}``, ``${temp min c}``, ``${weather}``, ``${wind aim}``, ``${wind deg}``, ``${wind kmh}`` and ``${wind mps}``, 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``: Temperature of requested graphics device * ``$6``: Frequency of GPU core * ``$7``: Memory transfer rate vicious.contrib.nvsmi ^^^^^^^^^^^^^^^^^^^^^ Provides (very basic) information about Nvidia GPU status from SMI Supported platforms: platform independent * Argument (optional): card ID as an argument, e.g. ``"1"``, default to ID 0 * Returns an array containing temperature of requested graphics device vicious.contrib.ossvol ^^^^^^^^^^^^^^^^^^^^^^ vicious.contrib.pop ^^^^^^^^^^^^^^^^^^^ vicious.contrib.pulse ^^^^^^^^^^^^^^^^^^^^^ Provides volume levels of requested pulseaudio sinks and functions to manipulate them * Argument (optional): name of a sink as an optional argument. A number will be interpret as an index, if no argument is given, it will take the first-best. To get a list of available sinks run ``pacmd list-sinks | grep 'name:'``. * Returns an array whose only element is the volume level vicious.contrib.pulse.add(percent[, sink]) """""""""""""""""""""""""""""""""""""""""" * ``percent`` is the percentage to increment or decrement the volume from its current value * Returns the exit status of ``pacmd`` vicious.contrib.pulse.toggle([sink]) """""""""""""""""""""""""""""""""""" * Toggles mute state * Returns the exit status of ``pacmd`` vicious.contrib.rss ^^^^^^^^^^^^^^^^^^^ vicious.contrib.sensors ^^^^^^^^^^^^^^^^^^^^^^^ vicious.contrib.wpa ^^^^^^^^^^^^^^^^^^^ Provides information about the wifi status. Supported Platforms: platform independent, requiring ``wpa_cli``. * Argument: the interface, e.g. ``"wlan0"`` or ``"wlan1"`` * Returns a table with string keys: ``${ssid}``, ``${qual}``, ``${ip}``, ``${bssid}`` Usage Examples -------------- PulseAudio Widget ^^^^^^^^^^^^^^^^^ .. code-block:: lua 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 ^^^^^^^^^^^^^^^ .. code-block:: lua 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" } })
