Vicious

Vicious is a modular widget library for window managers, but mostly catering to users of the "awesome" window manager. It was derived from the old "Wicked" widget library, and has some of the old Wicked widget types, a few of them rewritten, and a good number of new ones:

• https://github.com/Mic92/vicious

Vicious widget types are a framework for creating your own widgets. Vicious contains modules that gather data about your system, and a few "awesome" helper functions that make it easier to register timers, suspend widgets and so on. Vicious doesn't depend on any third party Lua libraries, but may depend on additional system utilities (see widget description).

Usage

When provided by an operating system package, or installed from source into the Lua library path Vicious can be used as a regular Lua library, to be used stand-alone or to feed widgets of any window manager (ie. Ion, WMII). It is compatible with both Lua v5.1 and v5.2.

  $ lua
  > widgets = require("vicious.widgets.init")
  > print(widgets.volume(nil, "Master")[1])
    100

Usage within Awesome

To use Vicious with Awesome, install the package from your operating system provider, or download the source code and move it to your awesome configuration directory in $XDG_CONFIG_HOME (usually ~/.config):

$ mv vicious $XDG\_CONFIG\_HOME/awesome/

Vicious will only load modules for widget types you intend to use in your awesome configuration, to avoid having useless modules sitting in your memory.

Then add the following to the top of your rc.lua:

local vicious = require("vicious")

Once you create a widget (a textbox, graph or a progressbar) call vicious.register() to register it with Vicious:

vicious.register(widget, wtype, format, interval, warg)

widget

• widget created with widget() or awful.widget() (in case of a graph or a progressbar)

wtype

• widget type or a function
  • any of the available (default, or custom) widget types can be used here, see below for a list of those provided by Vicious
• function
  • custom functions from your own "awesome" configuration can be registered as widget types, see the "Custom widget types" section

format

• string argument or a function
  • $1, $2, $3... will be replaced by their respective value returned by the widget type, some widget types return tables with string keys, in that case use: ${key}
• function
  • function(widget, args) can be used to manipulate data returned by the widget type, more about this below

interval

• number of seconds between updates of the widget, 2s by default, also read the "Power" section below

warg

• some widget types require an argument to be passed, for example the battery ID

Other functions

Unregister a widget:

    vicious.unregister(widget, keep)

if keep is true widget will be suspended, waiting to be activated

Suspend all widgets:

    vicious.suspend()

example automation script for the "laptop-mode-tools" start-stop module:

Restart suspended widgets:

vicious.activate(widget)

if widget is provided only that widget will be activated

Enable caching of a widget type:

    vicious.cache(wtype)

enable caching of values returned by a widget type

Force update of widgets:

    vicious.force({ widget, })

widget argument is a table with one or more widgets that will be updated

Get data from a widget:

    vicious.call(wtype, format, warg)

Fetch data from a widget to use it outside from the titlebar (see example section)

Widget types

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.

Custom widget types

Use any of the existing widget types as a starting point for your own. Write a quick worker function that does the work and plug it in. How data will be formatted, will it be red or blue, should be defined in rc.lua (or somewhere else, outside the actual module).

Before writing a widget type you should check if there is already one in the contrib directory of Vicious. The contrib directory contains extra widgets you can use. Some are for less common hardware, and other were contributed by Vicious users. Most of the contrib widgets are obsolete. Contrib widgets will not be imported by init unless you explicitly enable it, or load them in your rc.lua.

Some users would like to avoid writing new modules. For them Vicious kept the old Wicked functionality, possibility to register their own functions as widget types. By providing them as the second argument to vicious.register. Your function can accept "format" and "warg" arguments, just like workers.

Power and Caching

When a lot of widgets are in use they, and awesome, can generate a lot of wake-ups and also be very expensive for system resources. This is especially important when running on battery power. It was a big problem with awesome v2 and widgets that used shell scripts to gather data, and with widget libraries written in languages like Ruby.

Lua is an extremely fast and efficient programming language, and Vicious takes advantage of that. But suspending Vicious widgets is one way to prevent them from draining your battery, despite that.

Update intervals also play a big role, and you can save a lot of power with a smart approach. Don't use intervals like: 5, 10, 30, 60... to avoid harmonics. If you take the 60-second mark as an example, all of your widgets would be executed at that point. Instead think about using only prime numbers, in that case you will have only a few widgets executed at any given time interval. When choosing intervals also consider what a widget actually does. Some widget types read files that reside in memory, others call external utilities and some, like the mbox widget, read big files.

Vicious can also cache values returned by widget types. Caching enables you to have multiple widgets using the same widget type. With caching its worker function gets executed only once - which is also great for saving power.

• Some widget types keep internal data and if you call one multiple times without caching, the widget that executes it first would modify stored values. This can lead to problems and give you inconsistent data. Remember it for widget types like CPU and Network usage, which compare the old set of data with the new one to calculate current usage.

• Widget types that require a widget argument to be passed should be handled carefully. If you are requesting information for different devices then caching should not be used, because you could get inconsistent data.

Security

At the moment only one widget type (Gmail) requires auth. information in order to get to the data. In the future there could be more, and you should give some thought to the issue of protecting your data. The Gmail widget type by default stores login information in the ~/.netrc file, and you are advised to make sure that file is only readable by the owner. Other than that we can not force all users to conform to one standard, one way of keeping it secure, like in some keyring.

First let's clear why we simply don't encrypt the login information and store it in ciphertext. By exposing the algorithm anyone can reverse the encryption steps. Some claim even that's better than plaintext but it's just security trough obscurity.

Here are some ideas actually worth your time. Users that have KDE (or parts of it) installed could store their login information into the Kwallet service and request it via DBus from the widget type. It can be done with tools like "dbus-send" and "qdbus". The Gnome keyring should support the same, so those with parts of Gnome installed could use that keyring.

Users of GnuPG (and its agent) could consider encrypting the netrc file with their GPG key. Trough the GPG Passphrase Agent they could then decrypt the file transparently while their session is active.

Usage examples

Start with a simple widget, like date. Then build your setup from there, one widget at a time. Also remember that besides creating and registering widgets you have to add them to a wibox (statusbar) in order to actually display them.

Date widget

    datewidget = wibox.widget.textbox()
    vicious.register(datewidget, vicious.widgets.date, "%b %d, %R")

updated every 2 seconds (the default interval), uses standard date sequences as the format string

Memory widget

    memwidget = wibox.widget.textbox()
    vicious.cache(vicious.widgets.mem)
    vicious.register(memwidget, vicious.widgets.mem, "$1 ($2MB/$3MB)", 13)

updated every 13 seconds, appends "MB" to 2nd and 3rd returned values and enables caching of this widget type

HDD temperature widget

    hddtempwidget = wibox.widget.textbox()
    vicious.register(hddtempwidget, vicious.widgets.hddtemp, "${/dev/sda} °C", 19)

updated every 19 seconds, requests the temperature level of the {/dev/sda} key/disk and appends "°C" to the returned value, does not provide the port argument so default port is used

Mbox widget

    mboxwidget = wibox.widget.textbox()
    vicious.register(mboxwidget, vicious.widgets.mbox, "$1", 5, "/home/user/mail/Inbox")

updated every 5 seconds, provides full path to the mbox as an argument

Battery widget

    batwidget = wibox.widget.progressbar()

    -- Create wibox with batwidget
    batbox = wibox.widget {
      {
        max_value     = 1,
        widget        = batwidget,
        border_width  = 0.5,
        border_color  = "#000000",
        color         = {
          type = "linear",
          from = { 0, 0 },
          to = { 0, 30 },
          stops = {
            { 0, "#AECF96" },
            { 1, "#FF5656" }
          }
       }
      },
      forced_height = 10,
      forced_width  = 8,
      direction     = 'east',
      color         = beautiful.fg_widget,
      layout        = wibox.container.rotate,
    }
    batbox = wibox.layout.margin(batbox, 1, 1, 3, 3)
    -- Register battery widget
    vicious.register(batwidget, vicious.widgets.bat, "$2", 61, "BAT0")

updated every 61 seconds, requests the current battery charge level and displays a progressbar, provides "BAT0" battery ID as an argument

CPU usage widget

    cpuwidget = awful.widget.graph()
    cpuwidget:set_width(50)
    cpuwidget:set_background_color("#494B4F")
    cpuwidget:set_color({ type = "linear", from = { 0, 0 }, to = { 50, 0 },
      stops = { { 0, "#FF5656" }, { 0.5, "#88A175" }, { 1, "#AECF96" }}})
    vicious.register(cpuwidget, vicious.widgets.cpu, "$1", 3)

updated every 3 seconds, feeds the graph with total usage percentage of all CPUs/cores

Format functions

You can use a function instead of a string as the format parameter. Then you are able to check the value returned by the widget type and change it or perform some action. You can change the color of the battery widget when it goes below a certain point, hide widgets when they return a certain value or maybe use string.format for padding.

• Do not confuse this with just coloring the widget, in those cases standard pango markup can be inserted into the format string.

The format function will get the widget as its first argument, table with the values otherwise inserted into the format string as its second argument, and will return the text/data to be used for the widget.

Example

    mpdwidget = wibox.widget.textbox()
    vicious.register(mpdwidget, vicious.widgets.mpd,
     function (widget, args)
       if   args["{state}"] == "Stop" then return ""
       else return '<span color="white">MPD:</span> '..
             args["{Artist}"]..' - '.. args["{Title}"]
       end
     end)

hides the mpd widget when no song is playing, updated every 2 seconds (the default interval)

Example

    uptimewidget = wibox.widget.textbox()
    vicious.register(uptimewidget, vicious.widgets.uptime,
      function (widget, args)
        return string.format("Uptime: %2dd %02d:%02d ", args[1], args[2], args[3])
      end, 61)

uses string.format for padding uptime values to a minimum amount of digits, updated every 61 seconds

When it comes to padding it is also useful to mention how a widget can be configured to have a fixed width. You can set a fixed width on your textbox widgets by changing their .width field (by default width is automatically adapted to text width).

Example

    uptimewidget = wibox.widget.textbox()
    uptimewidget.width, uptimewidget.align = 50, "right"
    vicious.register(uptimewidget, vicious.widgets.uptime, "$1 $2:$3", 61)

forces a fixed width of 50px to the uptime widget, and aligns its text to the right

Another use case are stacked graphs (aka multigraphs) which Vicious does not handle on its own at the moment, as it's hard to pass on color index arguments elegantly. But they are not unusable, far from it.

Example

    ctext = wibox.widget.textbox()
    cgraph = awful.widget.graph()
    cgraph:set_width(100):set_height(20)
    cgraph:set_stack(true):set_max_value(100)
    cgraph:set_background_color("#494B4F")
    cgraph:set_stack_colors({ "#FF5656", "#88A175", "#AECF96" })
    vicious.register(ctext, vicious.widgets.cpu,
      function (widget, args)
        cgraph:add_value(args[2], 1) -- Core 1, color 1
        cgraph:add_value(args[3], 2) -- Core 2, color 2
        cgraph:add_value(args[4], 3) -- Core 3, color 3
      end, 3)

enables graph stacking/multigraph and plots usage of all three CPU cores on a single graph, the textbox "ctext" is just an empty placeholder, graph is updated every 3 seconds

A lot of users are not happy with default symbols used in volume, battery, cpufreq and other widget types. You can use your own symbols without any need to modify modules.

Example

  volumewidget = wibox.widget.textbox()
  vicious.register(volumewidget, vicious.widgets.volume,
    function(widget, args)
      local label = { ["♫"] = "O", ["♩"] = "M" }
      return "Volume: " .. args[1] .. "% State: " .. label[args[2]]
    end, 2, "PCM")

• uses a custom table map to modify symbols representing the mixer state; on or off/mute

How to get the data from a widget to use it outside from the taskbar? This could be useful for naughty notification and scripts.

Example

    -- Battery widget
    mybattery = wibox.widget.textbox()
    vicious.register(mybattery, vicious.widgets.bat, "$2%", 17, "0")
    mybattery:buttons(awful.util.table.join(
        awful.button({ }, 1, function()
            naughty.notify({ title = "Battery indicator",
                             text = vicious.call(vicious.widgets.bat, "Remaining time: $3", "0") })
        end)
    ))

Format functions can be used as well:

Example

    -- Battery widget
    mybattery = wibox.widget.textbox()
    vicious.register(mybattery, vicious.widgets.bat, "$2%", 17, "0")
    mybattery:buttons(awful.util.table.join(
        awful.button({ }, 1, function()
            naughty.notify({ title = "Battery indicator",
                             text = vicious.call(vicious.widgets.bat, function(widget, args)
                                 return string.format("%s: %10sh\n%s: %14d%%\n%s: %12dW",
                                                      "Remaining time", args[3],
                                                      "Wear level", args[4],
