Shows and controls keyboard layouts and variants using setxkbmap.

mykbdlayout = lain.widgets.contrib.kbdlayout()

input table

Variable	Meaning	Type	Default
layouts	Keyboard layouts and variants to switch between	table	none
add_us_secondary	Whether to add us as a secondary layout	boolean	true
timeout	Refresh timeout (in seconds)	int	10
settings	User settings	function	empty function

• layouts

  A table (array) which contains tables with keys indicating layout and (optionally) variant. This argument is mandatory.

• add_us_secondary

  A boolean controlling whether to add us as a secondary layout. This is needed in order for keyboard shortcuts to work in certain applications, i.e. Firefox, while using a non-US keyboard layout.

• timeout

  An integer which determines the interval at which the widget will be updated, in case the keyboard layout was changed by other means.

• settings

  A "callback" function in which the user is expected to set the text widget up. The widget itself is available as the global variable widget, while layout information is available as kbdlayout_now. kbdlayout_now contains two keys, layout containing the primary layout, and variant, containing the variant. If there is no variant, variant is nil.

output table

Variable	Meaning	Type
widget	The widget (textbox)	awful.widget.textbox
update	Function to update the widget and call settings	function
set	Function taking an index as an argument to manually set the layout given by that index	function
next	Change to the next layout	function
prev	Change to the prev layout	function

usage

The textbox can be added to the layout via standard means:

right_layout:add(mykbdlayout)

By default, left-clicking the textbox calls next, and right-clicking calls prev. You can set up additional key- or mouse-bindings. See the example below.

example

-- Switch between US Dvorak and DE layouts.
mykbdlayout = lain.widgets.contrib.kbdlayout({
                  layouts = {{ layout="us", variant="dvorak" },
                             { layout="de" }},
		          settings = function ()
                      if kbdlayout_now.variant then
                          widget:set_text(" " .. kbdlayout_now.layout .. "/" .. kbdlayout_now.variant .. " ")
                      else
                          widget:set_text(" " .. kbdlayout_now.layout .. " ")
                      end
                  end
})

-- Add to the layout.
right_layout:add(mykbdlayout)

-- Add this key binding to your global keys to
-- add traditional Alt+Shift switching.
awful.key({ "Mod1" }, "Shift_L", function () mykbdlayout.next() end)
