Can anyone isolate the code for one of these gauges please? [SOLVED]

[Koentje]

Have you played with the alpha numbers?
I think the colors do fade into each other when you set them to 0.5 instead of 1.0.

I haven't, I am a bit groggy today from a crappy night trying to sleep. I may crash for a bit then experiment with the gauges more when I am more alert.

I can clean up that code quite a bit. Those edits were just using copy/paste to represent the idea.

I kinda liked seeing the whole thing go uncontrollably blaring red all of a sudden!

-but wondering if the whole active bar should be represented by the current color.

It looks good and clean, and clear though, and with the data and labels changing colors i guess that does flash some attention into your peripheral view.

I kept the edit that produced the color change across the entire gauge and text just to be able to refer back to it if desired, but the gauges I added to my Minimalis display are the clean edits you provided, and a set that Koentje edited. They look beautiful!

Hey Zcot,

Can you show me what part of the code determines the ranges of med, warn, and alarm?

I note that med, the yellow range is really small and warn the orange range is large

I would like to edit this to add about 15-20% to yellow/med and subtract the same from orange/warn

Can you do this edit or explain to me how I can do it please?

I just used the numbers you had mentioned in your prior post, easily changeable though.

look at my previous post, it's in the conky config when you call it, and i added to the comment. you can see the zones. medium warn alert.

Good Morning Zcot,

I woke up a little ill this morning but I will take a look at the documentation you left and see if I can puzzle out the edit

Im not seeing it. I just opened up the .lua and started at the top and searched "med" and all I see is variables divided by variables an no numeric values to set anywhere in the .lua.

I'm afraid I will need a bit more help to perform the edit.

[zcot]

this is that sample(notice the hard coded sample values), notice the additional input parameter called medium, so the zones are OK/Medium/Warn/Alarm.

Code: Select all

# ... label/(no spaces) unit/(type nil if blank) measure/(conky_parse) max medium warn alarm xr yc ...
${lua conky_gauge CPU % ${cpu cpu0} 100 35 50 80 25 50 }
${lua conky_gauge CPU1 % 30 100 35 50 80 70 50 }
${lua conky_gauge CPU2 % 45 100 35 50 80 115 50 }
${lua conky_gauge CPU3 % 65 100 35 50 80 160 50 }
${lua conky_gauge CPU4 % 95 100 35 50 80 205 50 }

It's not in the lua file.

look in the config file.

specifically look at the comment line:

Code: Select all

# ... label/(no spaces) unit/(type nil if blank) measure/(conky_parse) max medium warn alarm xr yc ...

now compare that to a call of the gauge as in this example:

Code: Select all

${lua conky_gauge CPU % ${cpu cpu0} 100 35 50 80 25 50 }

you can see that medium warn alarm are defined as 35 50 80.

-those are the numbers you specified in an earlier post. just change them to your liking.

35 starts the medium zone
50 starts the warn zone
80 starts the alarm zone

ah I see. I feel foolish for not checking out the config fill.

As always, thank you for saving me from myself Zcot

Have a great weekend, I'm off to do edits!

I actually use the same code for the gauges, I forget where I found it.

Do you guys see errors in your ~/.xsession_errors file with these lines?:

Code: Select all

conky: Bad arguments: ' ' and ' 60'
conky: compare failed for expression ' <= 60'
conky: llua_getnumber: function conky_loadavg didn't return a number, result discarded
conky: llua_do_call: function conky_loadavg execution failed: ~/.conky/conky_myluafunctions.lua:130: attempt to perform arithmetic on a nil value (local 'value')

The line in question is:
local pct = value/max

My conky_rc is calling it like so:
${if_match ${lua conky_loadavg} <= 60}${color white}
and
${lua conky_gauge FAN % ${exec sensors | grep Right | cut -c14-18 | awk '{print (($1-1985)/4200)*100}' | awk '{printf "%.0f\n", $1}'} 100 40 80 132 139 }

If I run conky on the command line I also see them.

I think it has to do with lua trying to process the value and is expecting a number, but since it is empty, it displays an error. It's not a huge deal but sometimes it can spam the ~/.xsession_errors file.

PS.
I also have this function defined in the same lua file as conky_gauge:

Code: Select all

function conky_loadavg()
    loadavg = conky_parse("${loadavg 1}") / 8
    loadavg_graphval = string.sub(loadavg, 3, 4)
    loadavg_graphval_no_leading_zeroes = string.gsub(loadavg_graphval, '0*', '', 1)
    return loadavg_graphval_no_leading_zeroes
end

[zcot]

Code: Select all

conky: Bad arguments: ' ' and ' 60'
conky: compare failed for expression ' <= 60'
conky: llua_getnumber: function conky_loadavg didn't return a number, result discarded
conky: llua_do_call: function conky_loadavg execution failed: ~/.conky/conky_myluafunctions.lua:130: attempt to perform arithmetic on a nil value (local 'value')

first 2 lines show failure because nil is returned from lua conky_loadavg,
-we know those 2 lines refer to the conky_rc line: ${if_match ${lua conky_loadavg} <= 60}${color white}

the next 2 lines go further up to where the problem is starting, which we know is the lua scripting but you mention conky_gauge but the error mentions conky_myluafunctions.lua, so quite confusing as to what the real chain of process is on that, and it would be hard to start guessing other than starting from scratch and showing an entirely different solution.

you also throw in this comment about the conky_gauge line, but I can not understand where that interacts with any of this.

In a case like this, if you just show some snippets, it's hard to really troubleshoot. The functionality is there, and even though there's not enough code to see exactly how it all works, it does look like it's part of a larger functional scripting setup.

Why don't you post the scripts so we can see all the calls and relationship of those snippets.

Can you post a screenshot of your conky? I would like to see what your Minimalis looks like.

[Koentje]

conky.config = {
....
--function used to allow load to be displayed divided by # of CPUs (because otherwise it shows load as too high)
-- conky_loadavg() - need to divide load by the 8 (virtual) cores on this machine.
lua_load = '~/.conky/conky_myluafunctions.lua',
lua_draw_hook_pre = 'main'
}; <--- needs a semicolon here!


conky.text = [[
....
| sed 's/http[^ ]*//g' | fold -sw 30 | sed 's/| |//' | perl -pe 'chomp if eof'}${font}\
${endif}
${voffset -87}
]]; <--- and here!

Missing semicolons..

[minthelp777]

The semicolons didn't seem to make a difference, unfortunately. Thanks, though.

Code: Select all

conky: Bad arguments: ' ' and ' 60'
conky: compare failed for expression ' <= 60'
conky: llua_getnumber: function conky_loadavg didn't return a number, result discarded
conky: llua_do_call: function conky_loadavg execution failed: ~/.conky/conky_myluafunctions.lua:130: attempt to perform arithmetic on a nil value (local 'value')

first 2 lines show failure because nil is returned from lua conky_loadavg,
-we know those 2 lines refer to the conky_rc line: ${if_match ${lua conky_loadavg} <= 60}${color white}

the next 2 lines go further up to where the problem is starting, which we know is the lua scripting but you mention conky_gauge but the error mentions conky_myluafunctions.lua, so quite confusing as to what the real chain of process is on that, and it would be hard to start guessing other than starting from scratch and showing an entirely different solution.

you also throw in this comment about the conky_gauge line, but I can not understand where that interacts with any of this.

In a case like this, if you just show some snippets, it's hard to really troubleshoot. The functionality is there, and even though there's not enough code to see exactly how it all works, it does look like it's part of a larger functional scripting setup.

Why don't you post the scripts so we can see all the calls and relationship of those snippets.

Not sure what I did but all those errors went away. Then I was only getting a couple of these lines when I would first launch conky on the command line:

Code: Select all

conky: llua_do_call: function conky_gauge execution failed: /home/<username>/.conky/conky_myluafunctions.lua:130: attempt to perform arithmetic on a nil value (local 'value')

And then I added this code on line 130, right after local value = tonumber(str):

Code: Select all

if value == nil then
  return ''
end

It returns an empty string if 'value' is 'nil' (because the original input was nil, which I think was p_measure, the third argument being passed into conky_gauge).

Anyway, now I get no more errors. Thanks again guys.
