Hi all I think this may be a good place to post this, Ive been trying to make a conky config to show the current LTC and BTC price but having some problems. Anyone have a basic config to do this? Thanks!

You're asking for something specific not something that someone just might have laying around. But you're in luck - a bit ... someone one asked over on Ubuntu asked about BIT coins:

Conky line just using execi to call the script. (Use your path to script)

I tried it and it works:

So what exactly is the problem you ate having?

Hi there, after much struggling, I'm afraid I have to ask you gurus here.
It just does not work.
$cpugraph should change color dependent on CPU load.
Whilst I could do this with built-in conky variables, I might need EIGHT nested end-ifs for the various intervals, since conky syntax does not support true "else if" (it's horrid).

${execpi 0.5 /home/serr/.conkyhelper_cpugraph.sh ${cpu}}

#!/bin/bash
# uses conky code; must be executed via execpi / texecpi ((t)execi won't parse)

# cval=$(echo "\${cpu}"
cval=$1
ccolor=""

# note the following case..esac block is heavily simplified, in reality it is way longer
case "$cval" in
  100|[6-9][0-9])          # 60..100
     ccolor="cc1f1f" ;;
  [3-5][0-9])           # 30...59
     ccolor="e9f500" ;;
  *) 
     ccolor="1f2d8f" ;;
esac
echo "\${cpugraph 17, 0 b7b7b7 $ccolor}"

Unfortunately, it will always fall back into the default *) case.
Debugging revealed that it doesn't even get the parameter that I've passed over from my .conkyrc.
Tried with quotes, without quotes ... to no avail.
When Conky is running, I can see the value, but I cannot use it as criteria in my bash script.

Has anyone ever successfully managed this?

Script works on shell in dry-run, with cval set to $1.

^ ${execpi} only parses conky objects in the string returned by your script not in the command you execute so this will not work.

${execpi 0.5 /home/serr/.conkyhelper_cpugraph.sh ${cpu}}

This command is the equivalent of running

/home/serr/.conkyhelper_cpugraph.sh ${cpu}

in a terminal because of that.

You can do this with a Lua script that reads the ${cpu} value and calculates the color before passing it to something that draws the graph.
I don't know if you can call ${cpugraph} from a Lua script (I don't know if that would even work) or if you need to draw the graph with cairo in Lua for something this simple however?

I may not have time to look into that before Tuesday but someone else may already know and can help you before then.

@ syntaxerror

You could look at using Crinos512's colorize.sh script, it will colour three values. Assign color7, color8, and color9 to COOL, WARM, and HOT respectively oe Low, Med, High

@ arclance - yea, Ill bet LUA could do it, unfortunately I'm lua illiterate.

syntaxerror · 2014-09-14 23:49:09

@ arclance - yea, Ill bet LUA could do it, unfortunately I'm lua illiterate.

Me too! I'd like to be able to change things around myself later, so this is why I'd like to do without LUA if possible.

Thanks so far, I've checked out Crinos' colorize script, but if I am permitted to say so, his explanation is horribly confusing and not sticking to facts. Plus, I don't see how he is passing ${...} values directly to a bash script from within Conky; the .sh is executed without parameters.

@ syntaxerror

I'll have an example for you shortly ....

syntaxerror · 2014-09-15 00:26:54

Well...I'm further already!
Parameter passing works fine now ... just ... sh is still thwarting my plans, because it will always EXECUTE the line in question...

${execpi 0.5 $(echo '53' | xargs /home/serr/.conkyhelper_cpugraph.sh)}

(hardcoding value just to check if it jumps in correct case block)

Well, it worked! Color value is now known in my bash script.
But now SH stubbornly wants to execute my conky line as-is, as if it were a file:

echo "\${cpugraph 17, 0 b7b7b7 $ccolor}"

sh: 1: ${cpugraph: not found

He is not passing values from conky directly to bash he is using things likes this

sensors | grep 'Core 0' | paste -s | cut -c15-18

to get the temperature of "Core 0" from the sensors program and then passes the result of that to his bash script with this part.

 | xargs ~/.conky/conkyparts/colorize.sh

The script sends something determined by that value from sensors back to conky.

syntaxerror · 2014-09-15 01:10:59

OK, you've won.

Yes I've now understood how he does it: he BYPASSES the internal conky parameter that calculates the cpu TEMP by using 'sensors' as an external tool to get the same result.

[edit] I GOT IT!!

Thanks for the help everyone, now that you had the will to bear with me, the profit will be on YOU!
The 7th (!) approach actually worked. I knew that ${eval} must be the key, just had to study several LUA calls to get the right idea how to pass the parameters to the bash script. Plus, it took so long because the lackluster kind of way that ${eval} is officially documented may almost be called a great impudence. Can't word it any differently, sorry.

${eval $${execpi 0.5 ~/.conkyhelper_cpugraph.sh ${cpu}}}

Now all I need to do is obtaining PERFECTLY smooth color gradient values for each single cpu usage percentage, and voila !!

So much for "you cannot pass parameters to bash, just vice-versa."

Case successfully closed.

Has anyone got/know how to make conky show time since the laptop was unplugged?

Showing the last, current, best, and average would be awsome, similar to what's available for phones....

Any pointers?

PackRat · 2014-09-15 20:05:35

^ You might be able to get that information from upower, and run the scripts in conky. I don't know if it's installed by default with #!.

I did not know about ${eval} because I do everything in lua, good research on that.

This is an example of how to calculate a gradient between two RGB colors in Lua.

function linear_gradient(Left_Color, Right_Color, Length, Position)
	local positionPercent = Position/Length
	local red = Right_Color[1] + (math.abs(Right_Color[1] - Left_Color[1]) * positionPercent)
	local green = Right_Color[2] + (math.abs(Right_Color[2] - Left_Color[2]) * positionPercent)
	local blue = Right_Color[3] + (math.abs(Right_Color[3] - Left_Color[3]) * positionPercent)
	return red,green,blue
end --# function linear_gradient()

You would use the percentage a temperature was between two different reference temperatures (0 and 100 C for example) for positionPercent instead of what is used here.

Right_Color would be your low temperature color and Left_Color would be your high temperature color.
They are RBG triplets in an array like {255,255,255}.
math.abs returns the absolute value of the input value.
Conky wants color hexcodes so you would need to convert to that before you could use it.

This what I use to give the graphs in my conky a horizontal gradient.

I have no idea how you do math in a shell script though so I can't help with that.

I've done the math in my head, which worked as well to some extent

Found this on wikimedia:
http://upload.wikimedia.org/wikipedia/c … GB.svg.png

First of all, I set a fixed width at 150, between 460 and 610 nanometers in spectral light, so each cpu percent will be 1.5 nanometers.
Then I turned on my "Rainbow" (Firefox add-on), selected "Color Inspector", used suitable steps (skipping a bit, since too narrow skip intervals won't occur as color change to the inert human eye), noted them down and built my array of 100 pretty homogenous values.

That was GOOD.

To get things to the 'VERY good' level, I would need one decimal of CPU usage (e. g. 57.3 percent) to create interim values. However, I haven't found any tool that can output realtime CPU usage in short intervals AND in high frequency.
'mpstat 2 1' takes up to 1 whole second to calculate, so I can't use that.

Hello all. I am relatively new to conky and have a minimal desktop system monitoring config that I am very happy with, but I have one annoying issue. The conky update seems to overwrite what is already on the screen so that I have both old and new information on the screen at the same time. The effect is that it gets blurry and unreadable over time. Any advice would be kindly appreciated. I have included my conkyrc below...

Hey all. So, I'm new to linux, new to conky, new to it all. Been using windows forever, super comfortable with doing anything on windows.... And then my HDD in my laptop crashed, and I'm not in a place where I can buy a new one just yet. So I grabbed the 4gb spare flashdrive that I have sitting around, got on a friends PC and looked into which versions of Linux I could throw on it that were full functioning. For some insane reason I chose Crunchbang over the more GUI filled, user-friendly types like Linux Lite or some of the other, highly popular ones.

And I have fallen in love. There's a decent learning curve to someone that hasn't ever used an OS that's pretty terminal based, short of loading up games in the MS-Dos command line. But I must say, this is one OS that I have come to enjoy. I'm now using my mom's old dell desktop, that for some reason has a 750gb HDD inside it (apparently she upgraded a few years ago... not knowing that 750 was WAY more then she needed. Win! ) So now I'm sitting here playing around with Crunchbang with tons of space to play with, learning the ins and outs of this great OS.

To the point of this post. Over the past 3 days I've studied the coding that Tint2 and Conky use, respectively, and I've built what I can say is a rather appealing, yet simple, Conky. Here's my config and a screen

# conky configuration

@valinote: how are you starting conky?

valinote · 2014-09-23 18:27:16

Hi chepioq and head_on_a_stick. This is exactly what happens when people (me for instance) cut & paste things without really knowing what they are doing! I sat down and went through the conky parameters/values one by one and made sure that they were set correctly for what I was trying to accomplish. And also I found some redundancy and commands that were no longer supported. I should have done this before I posted in the forum. The end result is that now my system monitor is working correctly without the overwriting phenomenon. I appreciate your help and thank you for the quick replies. Kindest regards...8-]
