[LUA / DE] AwesomeWM & Vicious Widgets

Hello

Allthough i dont know LUA, despite its name, i do love the window manager that was created using that language.
By now, I'm enough familiar with LUA so i could adapt (most of) the recent changes so i have vicous widgets working again - by the means of no error messages on start up.

I managed to get the wifi info back, the volume value is shown, the hdd temp too and power left/until full works now too...
It was already challenging prior to the (upstream) changes done recently (6months) as the syntax was changed (vicious).
So, i managed to fix code i dont (really) understand, but got 'used' to, according to a syntax that had changed to something that i'm yet to explore...

What i want is help with:
* "Change output volume" (button press produce error message), also neither
* CPU temp

--------------------------------------------------
Contents of rc.lua - most of this is copy-pasted from diffrent sites and then little modified
--------------------------------------------------
Vicous-Volume-Control:
PHP Code:
    -- Volume widget
    hlcolor 
"#d7e0ea"
    
volumewidget wibox.widget.textbox()
    
volumewidget:buttons({
       
button({  }, 4, function () volume("up"volumewidgetend),
       
button({  }, 5, function () volume("down"volumewidgetend),
       
button({  }, 1, function () volume("mute"volumewidgetend)
    })
    
vicious.register(volumewidgetvicious.widgets.volume" Vol: <span color='" .. hlcolor .. "'>$1$2</span> | ",61"Master")
....
globalkeys awful.util.table.join(
....
    --

    awful

awful.key({ }, "XF86AudioLowerVolume", function () volume("down"volumewidgetend),
    
awful.key({ }, "XF86AudioMute", function () volume("mute"volumewidgetend), 
Vicious-cpu-temp
PHP Code:
-- cpu C
    thermwidget 
wibox.widget.textbox()
    
vicious.register(thermwidgetvicious.widgets.thermal"cpu $1 C"30, { "coretemp.0""core"}) -- ${core} ${proc}
    
    -- 
Author example fails ?!?
    -- 
vicious.register(tempwidgetvicious.widgets.thermal"Temp: <span color='" .. hlcolor .. "'>$1С</span> | ",37,"thermal_zone0")
    
    -- 
Future try?    -- thermal_zone0 fails :(
    -- 
vicious.register(tempwidgetvicious.widgets.thermal"cpu $1С",37,"thermal_zone0")
    -- 
sensors|grep "Core 0" |awk '{print $3}' 
The widget used for the CPU temp is thermal.lua:

end
    end

    
return {0}
end
-- }}}

return 
setmetatable(thermal, { __call = function(_, ...) return worker(...) end }) 
I hope these code segments are sufficant, otherwise the full config can be found at:
https://github.com/sri-arjuna/awesome-config (Vicious)

Basicly my issue is this, i dont know what to pass to the vicious.widgets (thermal,volume) to get the desired values/behaviour.

Thank you in advance

EDIT:
* CPU/MEM usage did work, the laptop just didnt use those much, so i didnt see any change of a flat line.
* Figured ${link} is signal strength for wifi device.
* Updated screenshot
* Added thermal.lua code, in hope of help

Heyas, keept trying...
PHP Code:
    -- INFO SYSTEM --
    -- 
cat /etc/system-release uname -r
    
-- Fedora release 21 (Rawhide)
    -- 
3.15.0-0.rc2.git0.1.fc21.x86_64
    
    
-- Try1:
    -- 
URL:     http://xor0110.wordpress.com/2010/05/10/cpu-core-temperature-with-vicious-without-acpi/
    
-- Reason:      He refers to a filecat /sys/devices/platform/coretemp.0/temp1_input,
    --         
Folder is availablebut no file indicating to 'temp'eratur or heat.
    
    -- 
Try2:
    -- 
URL:     https://bbs.archlinux.org/viewtopic.php?id=123941
    
-- Reason:     Confirms Try1its just 'temp2_input' nowalso not available on my system
But figured that file was moved even more..
Code:
/sys/devices/platform/coretemp.0/temp1_input
vs
/sys/devices/platform/coretemp.0/hwmon/hwmon2/temp[0-5]_input

At first i though i need to change the widget...
But on closer look figure i could change my rc.lua too.

Solved by changing 'orginal & working for most':
Code:
vicious.register(thermwidget, vicious.widgets.thermal, "cpu $1 C", 30, { "coretemp.0", "core"})

to working on fedora 21:
Code:
vicious.register(thermwidget, vicious.widgets.thermal, "cpu $1 C", 30, { "coretemp.0/hwmon/hwmon2", "core"})

Hope this helps others too.
