Vicious ------- Vicious is a modular widget library for the "awesome" window manager, derived from the "Wicked" widget library. It has some of the old Wicked widget types, a few of them rewritten, and a good number of new ones: http://git.sysphere.org/vicious/about/ Vicious widget types are a framework for creating your own widgets. Before using a widget type *you* need to ensure that a valid source of information exists. Usage ----- To use vicious move it to your awesome configuration directory in $XDG_CONFIG_HOME (usually ~/.config): $ mv vicious $XDG_CONFIG_HOME/awesome/ Your first step should be editing init.lua to comment out all the widget types you don't need from the "Configure widgets" list. It is not required but I suggest you do so to avoid having useless modules sitting in your memory. Then add the following to the top of your rc.lua: require("vicious") Once you create a widget (a textbox, graph or a progressbar) call vicious.register() to register it with vicious: vicious.register(widget, type, format, interval, warg) widget - widget created with widget() or awful.widget() (in case of a graph or a progressbar) type - one of the available widget types, see below for a list 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 custom 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: http://sysphere.org/~anrxc/local/sources/lmt-vicious.sh Restart suspended widgets: vicious.activate(widget) - if widget is provided only that widget will be activated Enable caching for a widget: vicious.enable_caching(widget_type) - enable caching of values returned by a widget type 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. Suspending widgets is one way to prevent them from draining your battery. Update intervals also play a big role, and you can save a lot of power with a smart approach. Avoid 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. 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. vicious.widgets.cpu - provides CPU usage for all available CPUs/cores - returns 1st value as usage of all CPUs/cores, 2nd as usage of first CPU/core, 3rd as usage of second CPU/core etc. vicious.widgets.cpuinf - provides speed and cache information for all available CPUs/cores -

returns the output of os.date(), formatted by provided sequences 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). 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 = widget({ type = 'textbox', name = 'datewidget' }) vicious.register(datewidget, vicious.widgets.date, '%b %d, %R') - executed every 2 seconds (the default interval), uses standard date sequences as the format string Memory widget memwidget = widget({ type = 'textbox', name = 'memwidget' }) vicious.enable_caching(vicious.widgets.mem) vicious.register(memwidget, vicious.widgets.mem, '$1 ($2MB/$3MB)', 13) - executed every 13 seconds, appends "MB" to 2nd and 3rd returned values and enables caching of this widget type HDD temperature widget hddtempwidget = widget({ type = 'textbox', name = 'hddtempwidget' }) vicious.register(hddtempwidget, vicious.widgets.hddtemp, '${/dev/sda}°C', 19) - executed 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 = widget({ type = 'textbox', name = 'mboxwidget' }) vicious.register(mboxwidget, vicious.widgets.mbox, '$1', 5, '/home/user/mail/Inbox') - executed every 5 seconds, provides full path to the mbox as an argument Battery widget batwidget = awful.widget.progressbar({ layout = awful.widget.layout.horizontal.rightleft }) batwidget:set_width(8) batwidget:set_height(10) batwidget:set_vertical(true) batwidget:set_background_color('#494B4F') batwidget:set_border_color(nil) batwidget:set_color('#AECF96') batwidget:set_gradient_colors({ '#AECF96', '#88A175', '#FF5656' }) vicious.register(batwidget, vicious.widgets.bat, '$2', 61, 'BAT0') - executed 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({ layout = awful.widget.layout.horizontal.rightleft }) cpuwidget:set_width(50) cpuwidget:set_max_value(100) cpuwidget:set_background_color('#494B4F') cpuwidget:set_color('#FF5656') cpuwidget:set_gradient_colors({ '#FF5656', '#88A175', '#AECF96' }) vicious.register(cpuwidget, vicious.widgets.cpu, '$1', 3) - executed 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, or maybe hide widgets when they return a certain value or... you get the point. - Do not confuse this with just coloring the widget, in those cases standard markup can be inserted into the format string. The format function will get the widget as its first argument, and a table with the values otherwise inserted into the format string as its second argument, and should return the text to be used for the widget. Example widget mpdwidget = widget({ type = 'textbox', name = 'mpdwidget' }) vicious.register(mpdwidget,vicious.widgets.mpd, function (widget, args) if args[1] == "Stopped" then return '' else return 'MPD: '..args[1] end end) - hides the mpd widget when there is no song playing, executed every 2 seconds (the default interval) Other ----- Read "awesome" manual pages: awesome(1) awesomerc(5) Authors "awesome" configuration: http://git.sysphere.org/awesome-configs/ Authors ------- Vicious, written by: Adrian C.
