conky-awesome
is a framework for making awesome widgets displaying system information from conky
conky-awesome
provides some optional keybindings to manange conky's own
X-window, but you can also run conky-awesome
headless by configuring conky
with out_to_x = false
and only have it update your widgets.
- conky
- awesome with dbus support
- lua bindings to dbus
Clone this repo to ~/.config/awesome/conky
conky.config = {
.....
lua_load = "~/.config/awesome/conky/conky-dbus.lua",
lua_draw_hook_pre = "conky_update_awesome",
}
local conky = require("conky")
This is all that is required to have conky start at launch. Restarting awesome will not spawn additional conky clients.
To launch conky with custom options, i.e. a different conkyrc
:
conky.options = "-c ~/.conky/my_special_conkyrc"
The conky client's own window defaults to being behind all other windows.
Bind keys for raising the client window on top.
globalkeys = awful.util.table.join(
awful.key( .....
.....
conky.show_key("F12"), -- conky window on top while held
conky.toggle_key("F12"), { modkey }) -- toggle conky on top
)
Both functions have this signature:
(keystring, [ modifier table ])
You can also provide functions to call when the window is raised and lowered
conky.raise = function(c) c.opacity = 1.0 end
conky.lower = function(c) c.opacity = 0.4 end
If you are running conky with a non-standard window class, by setting
own_window_class
in conkyrc
, you must also set this in rc.lua
for
the keybindings to work:
conky.class = "MyClass"
To set properties for the client window (defaults shown):
conky.properties = {
floating = true,
sticky = true,
ontop = false,
skip_taskbar = true,
below = true,
focusable = true,
titlebars_enabled = false,
}
For these properties to apply properly when awesome is started and restarted,
the following must be added to the Rules
section in awesome/rc.lua
:
awful.rules.rules = {
....
conky.rules()
}
Extra properties may be provided to be applied on launch, as per awful.rules:
awful.rules.rules = {
....
conky.rules({ properties = { tag = "3" }, callback = function(c) ... end })
}
Conky widget declaration:
{
icon = <string>, -- image filename
label = <string>, -- text for a label
conky = <string>, -- the string conky evaluates with conky_parse()
background = <table>, -- background properties table
updater = <function>, -- custom updater function
buttons = <table>, -- buttons to connect to the widget
signals = <table>, -- signals to connect to the widget
tooltip = <table>, -- tooltip for the widget
<wibox property> = <value> -- properties for the widgets
{ -- any number of child widgets:
<conky declaration>, -- nested conky widget declarations
<canned conky widget>, -- premade widgets from .config/awesome/conky/widgets
<any widget> -- to place other widgets in-between conky widgets
}
}
A conky widget consists of up to four subwidgets, all optional:
icon
declares a wibox.widget.imagebox instancelabel
declares a wibox.widget.textbox instanceconky
declares a wibox.widget.textbox instancebackground
declares a wibox.container.background instance
Simply declaring a string to be evaluated by conky:
s.mywibox:setup {
.....
conky.widget({ conky = "CPU: ${cpu}% MEM: ${memperc}% GPU: ${hwmon 0 temp 1}" }),
....
}
Simple example with an icon and a text label:
conky.widget({
icon = "my_neat_cpu_icon.png",
label = "CPU:",
conky = "${cpu}"
})
Setting wibox properties individually for subwidgets:
conky.widget({
label = "CPU:",
conky = "${cpu}",
-- properties for the background wibox
background = { bg = "red" },
-- properties for the label wibox
labelbox = { font = "Font for Label" },
-- properties for the conky wibox
conkybox = { force_width = 30, align = "right" },
-- properties for the icon wibox
iconbox = { opacity = 0.8 },
})
Child widgets inherit properties from their parents.
Any number of child widgets can be declared, and will be placed to the right of its parent.
conky.widget({
font = "My Neat Font",
label = "CPU:",
conky = "${hwmon 1 temp 1}", -- cpu temp
{ -- child widget 1 inherits "My Neat Font"
label = "Core 1:",
{ conky = "${cpu cpu1}" }, -- as does the grandchildren
{ conky = "${cpu cpu2}" },
},
{ -- child widget 2 inherits "My Neat Font"
label = "Core 2:",
{ conky = "${cpu cpu3}" }, -- as does the grandchildren
{ conky = "${cpu cpu4}" },
},
....
{
font = "Font for Ram" -- different font for RAM child widget
label = "RAM:"
conky = "${memperc}"
}
})
Child widgets inherit subwidget properties from their parent.
conky.widget({
label = "Parent",
background = { bg = "black" },
labelbox = { force_width = 30 },
{
label = "Child",
labelbox = { align = "right" },
{
-- this widget has a black background,
-- and a left-aligned label widget 30 pixels wide
label = "GrandChild",
labelbox = { align = "left" },
}
}
})
To change the widget based on updates from conky, provide an updater function with the following signature:
function updater(conky_update, conky_wibox, icon_wibox, label_wibox, background)
Where conky_update
is the update from conky, and the rest are the subwidget
wiboxes.
A CPU widget that changes its background color to red if the load goes above 80%:
conky.widget({
label = "CPU:",
conky = "${cpu}",
background = { bg = "grey" },
updater = function(conky_update, conky_wibox, _, _, background)
conky_wibox:set_text(conky_update)
if tonumber(conky_update) > 80 then
background.bg = "red"
else
background.bg = "grey"
end
end
})
Providing a table of button declarations allows you to change the widget based on button pressed.
A CPU widget that changes its background color to blue while the user holds CTRL and :
conky.widget({
label = "CPU:",
conky = "${cpu}",
background = { bg = "red" },
buttons = {
{ -- declaration of single button
{ "Control" }, -- table of modifiers
1, -- key, here <mouse1>
function(conkybox, iconbox, labelbox, background) -- function for
background.bg = "blue" -- button press
end,
function(conkybox, iconbox, labelbox, background) -- (optional) function
background.bg = "red" -- for button release
end
},
... -- more button declarations
}
})
Providing a table of signals and conky-awesome connects them for you.
A CPU widget showing the load on all four cores while the mouse hovers over it:
local cpu_widget = (function()
local conkyb = { -- properties are not passed to
forced_width = 30, -- already built child widgets, so
align = "right", -- shared properties are declared here
}
local cores = conky.widget({ -- building the widget here to close
conkybox = conkyb, -- up in signal functions below
{ conky = "${cpu cpu1}%" },
{ conky = "${cpu cpu2}%" },
{ conky = "${cpu cpu3}%" },
{ conky = "${cpu cpu4}%" },
})
cores.visible = false -- widget starts out with cores hidden
return { -- widget declaration
conkybox = conkyb, -- shared properties
conky = "${cpu}%", -- total load %
signals = {
['mouse::enter'] = function(conkybox, iconbox, labelbox, background)
cores.visible = true -- on hover, show cores and hide
conkybox.visible = false -- total load
end,
['mouse::leave'] = function(conkybox, iconbox, labelbox, background)
cores.visible = false -- reset when mouse leaves
conkybox.visible = true
end,
},
cores,
}
end)()
Simply a table to pass to awful.tooltip().
A simple 24 hour clock with a date tooltip:
conky.widget({
conky = "${time %R}",
conkybox = { align = "center" },
tooltip = {
timer_function = function() return os.date("%A %B %d %Y") end,
}
})
Canned widgets, located in awesome/conky/widgets/
, can be included by providing
its filename, without the lua extension, in place of any widget declaration.
conky.widget({
conky = "CPU: ${cpu}"
{
"battery" -- battery widget, from widgets/battery.lua
}
})
Canned widgets can be configured as follows:
conky.config.<widget> = { <option> = <value> }
To make a canned widget, have the module return a constructor function that takes a table of options and returns a widget declaration. The top of the file should contain a comment describing use and configuration.
-- usage
--[[
Description and instructions goes here
--]]
return function(options)
-- apply options
return {
-- declare widget
}
end
Please contribute if you make anything cool or useful.
Mixins, located in awesome/conky/mixins/
, are for extending a widget
declaration with common functionality. Below the keep-max
mixin extends
the CPU widget declaration with functionality that tracks and displays both
the current and highest value, in this case CPU core temperature.
conky.widget({
conky.mixin("keep-max", {
icon = beautiful["icon-hardware-cpu"],
conky = "${hwmon temp 2} ${hwmon 3 temp 3}",
{
conky = ${cpu}% ",
}
})
})
Any number of mixins may be provided, and they are applied in order to the provided declaration.
conky.mixin("keep-max", "alert-on", ..., <widget declaration>)
To make a mixin, have the module return a constructor function that takes a widget declaration to extend. The top of the file should contain a comment describing use and configuration.
-- usage
--[[

--]]
return function(widget_decl)
<define stuff>
<extend widget>
return widget_decl
end
conky-awesome
will eject widgets that are misbehaving. This means that the
widget will not receive further updates from conky
. A widget will be ejected
if it throws an error, of it receives an empty string as an update.
conky-awesome
will display a notification with a widget is ejected.
If you CTRL+RightClick
on the conky widget, conky-awesome
will display a
debug feed, showing the variables passed to conky
together with its last
updated value. The debug feed will also list ejected widgets.
If you change your .conkyrc
while conky is running, conky will restart itself
but appears to not be reloading its lua files. Conky will complain about
conky_update_awesome
being nil. Simply kill the process and start conky
manually.
If you start a nested awesome in Xephyr, you will need to start it in a
separate dbus session. You can do this by starting the nested awesome with
dbus-launch awesome
