Update 09.10.2022: fixed fehlende Farbe beim letzten Knopf wenn die Anzahl der Anwendungen, die Anzahl der hinterlegten Farben übersteigt
Nach dem Umstieg auf den awesome Windowmanager, bin ich echt begeistert, nur eins fehlte mir, ein Grid Select Menu, wie ich es von xmonad kannte. Ein Grid Select Menu zeigt mir als Overlay eine tabellarische Anordnung von Menüeinträgen / Anwendungsnamen aus denen ich dann auswählen kann und durch Klick oder Enter auf dem jeweiligen Eintrag die Anwendung starten kann.
Der awesome Windowmanager läßt sich in der Programmiersprache Lua erweitern und so habe ich eine kleine Routine geschrieben, mit der man awesome um ein Grid Select erweitern kann.
Dieses awesome widget kann bis zu 50 Menueinträge anzeigen und wird direkt über die rc.lua (Konfigurationsdatei von awesome und normalerweise im Verzeichnis ~/.config/awesome abgelegt).
Zuerst definiert man sich die gewünschten Menüeinträge und zugehörige Programme. Dabei ist der erste String der Text, der im Menü angezeigt wird und der zweite Stringe das Kommando, das bei Auswahl des Menüeintrages ausgeführt wird.
Das sieht dann z.B. so aus:
local my_appgrid = {
{"Chromium", "chromium"}, {"Thunderbird", "thunderbird"}
, {"Firefox", "firefox"}, {"Urxvt", "urxvt"}
, {"LibreOffice Calc", "localc"}, {"LibreOffice Writer", "lowriter"}
, {"PCManFM", "pcmanfm"}
}Code-Sprache: JavaScript (javascript)Um das Menü auch aufrufen zu können verknüpft man es dann mit einer Tastenkombination. Im folgenden Beispiel ist das <Mod4> + g.
awful.key({ modkey }, "g", function()
grid_select.launch({appgrid = my_appgrid}) end,
{description = "Show grid selection menu", group = "custom"}
)Code-Sprache: JavaScript (javascript)Dies Verknüpfung mit der Tastenkombination wird in rc.lua im Abschnitt globalkeys = mytable.join( … ) eingebaut.
Wer möchte kann sich auch eine andere Menge an Farben definieren. Dazu definiert man sich eine Tabelle von Farben und gibt diese als Parameter an das Widget mit.
local myColors = { „#9BB7D4“, „#C74375“, „#BF1932“, „#7BC4C4“, „#E2583E“, „#53B0AE“ }
Die Verknüpfung mit der Tastenkombination sieht dann so aus:
awful.key({ modkey }, "g", function()
grid_select.launch({appgrid = my_appgrid, colors = myColors}) end,
{description = "Show grid selection menu", group = "custom"}
)Code-Sprache: JavaScript (javascript)Das Widget wird wie folgt in rc.lua eingebunden:
local grid_select = require("grid-select-widget.grid-select")
Code-Sprache: JavaScript (javascript)Zum Abschluss der Sourcecode des Widgets, den man z.B. im Verzeichnis ~/.config/awesoem/grid-select/grid-select.lua ablegt.

-- To use this grid select widget, edit rc.lua
-- define your own commands in a table

and add a keybinding
awful.key({ modkey }, "g", function() grid_select.launch({appgrid = my_appgrid}) end, {description = "Show grid selection menu", group = "custom"})
somewhere in the
globalkeys = mytable.join( ... )
section in rc.lua
You can also change the colors defining your own color table
local myColors = { "#9BB7D4", "#C74375", "#BF1932", "#7BC4C4", "#E2583E", "#53B0AE" }
and change the keybinding accordingly to
awful.key({ modkey }, "g", function() grid_select.launch({appgrid = my_appgrid, colors = myColors}) end, {description = "Show grid selection menu", group = "custom"})
You can either define the selected entry by setting default_app to the number of the entry in my_appgrid, counting start at 1
local my_appgrid_default = 9
and change the keybindings according to
awful.key({ modkey }, "g", function() grid_select.launch({appgrid = my_appgrid, colors = myColors, default_app = my_appgrid_default}) end, {description = "Show grid selection menu", group = "custom"})
