Description:

Conky Basic displays only the most basic information about your system.
In the lua file you can change the color scheme used by Conky Basic, show all CPU cores or not and set a battery alert level.
You can also choose what to display, only CPU, storage, memory , details about storage etc..

Thanks to autocrosser1 and soundrolf for their ideas and code contributions

When using a laptop don't forget to set the show_battery option to yes.

If you modified Conky Basic make a backup of your files first before installing this version !!!

Installation
- unpack source file
- copy the file .conkybasic to your home directory
- copy the file .conkybasic_c110 to your home directory
- copy the basic folder into ~/.lua
- install the Unique font in ~/.lua/basic

Start conky via 'conky -c .conkybasic -q'
If you are using Conky version 1.10.0 start conky via 'conky -c .conkybasic_c110 -q'

Keep in mind that Conky 1.10.0 uses a new configuration file format and is still work in progress. That's why I used some work-arounds to get things working, so your mileage may vary.

hi soundrolf, I have just put a new version online which has a Radiotray tab. Just enable the user preference to make the tab visible.

hi soundrolf, I have a raw version working at the moment, still need to do some fine-tuning though about displaying text.

When it's ready I put it in the next version.

Well, spoke to soon. v0.5 still does work with ${cpu cpu2). Strange things is that if you put that same command in the TEXT [[]] in the rc file, the lua part works. Don't ask me why.

I will look if the radio part is possible autocrosser :)

Well, a quick and dirty workaround did the trick. In the .conkybasic_c110 file I put a ${cpu cpu1} call and set it offscreen. Then the lua part gets correctly processed and displays the CPU cores in Conky 1.10.0

Yes--that works :) I have 8 showing...Now a "odd one" and a couple of questions.

For some reason my /home is being shown as a separate "Root"--not sure why.

I wrote a couple of additional segments "CPU_Processes" & MEM_Processes"...they work, but when I move them around I get errors..Not sure how to add extra segments in....The cpu segment looks like this:

-- parameters idem conky_wired_tab_cpu_proc
function conky_wired_tab_cpu_proc(x,y,width,height,text,font,font_size,r,g,b)
local vuheight=15 --VU barheight
local onebarheight=vuheight+8
local basey=y
local barfs=12 -- VU bar fontsize

if height <= 60 then
print("ERROR conky_wired_tab_cpu_proc: insufficient height. Must be higher than 60")
return
end

local aspect=math.floor(height/60)
local corner_radius = height / 10.0
local radius = corner_radius / aspect
local degrees = math.pi / 180.0

conky_lctexta(x+width,y+15,text,font,font_size,r,g,b)

conky_lctexta(x+150,y+80,conky_parse("${top cpu 5}"),"Arial",11,themes.tred,themes.tgreen,themes.tblue)

return (x+width),(y+height)

end -- conky_wired_tab_cpu_proc

Second question is what is the easiest way to shuffle the order of the segments?

[For some reason my /home is being shown as a separate "Root"--not sure why.]
I only checked for the existance of a forward slash in a mountpoint name so it also caught /home as well.
On row 866 change the if statement in "if string.len(v) == 1 and r == 1 then" should fix that.
I will add this fix in the next release.

[what is the easiest way to shuffle the order of the segments?]
At the top of the code you find several "if show_memory == "yes" then [[code]] end" blocks to determine if a tab must be shown or not.
To rearrange the order of the tabs just cut and past a "if show_* then [[code]] end" block and place it below or above an other if/end block.

If you want to put a tab above the 'Processor' tab change the starty variable in the conky_wired_tab_cpu call to "rety+tabvsep"
I will add this change in the next release

I will add the "own_window_argb_visual = true" configuration option in the next release

Thanks for your feedback.

??? I just downloaded again & the basic.lua only goes to line 848.....line 866?

I also did a string search & that one is not showing up.

For a few moments it will display with 8 CPUs & try to start working, then it throws the "trying to use more cpus than you have" error & folds... Looked great while it was trying to work...Maybe someone playing with 1.10 over at Arch or Siduction might have a idea....If I find out anything I'll post it.

Thanks for trying!!!!

To bad :(
I had the same error about 'conky: attempting to use more CPUs than you have!' and thought I had it fixed. It does seem to work on my Ubuntu 15.10 though. You could try to set the squash_cpu option.

Otherwise it's time to go back to version 1.9.0

I just remembered from my programming in python---

conky: llua_do_call: function conky_main execution failed: /home/dean/.conky/basic.lua:670: 'for' limit must be a number

Is referring to for i=1,tonumber(hardware.cpucores) do
cpucores[i]=i

is not converting to a number-staying as text?

Well, it's definitively a conky version problem. Just updated my test system to Ubuntu15.10 which has conky 1.10.0 and I've got all the errors you described, $pre_exec, for 'limit must be a number' etc.

I will look in to it to see what needs to be changed.

In the mean time this script will only function correctly with conky version 1.9

Ah Well--it's what I pay for doing testing work...I have to admit that Sid has been very stable of late. I had to rebuild my install about a month ago & nothing has gone "wrong" lately (crossing my fingers as I say this). I keep a second install updated every week as a backup. It is "fun" to get software that needs to be debugged--I do enjoy the challenge.

Yep, that's the price of living on the edge :-)

The $pre_exec, for 'limit must be a number' errors I solved but now it keeps giving me errors on cpu. For some reason ${cpu cpu0} works wel but ${cpu cpu1} keeps on exiting conky

Still busy testing on conky 1.10.0

If you change the code into the following:
hardware.cpucores =tonumber(conky_parse("${pre_exec cat /proc/cpuinfo | grep 'processor' | wc -l}"))
for i=1,hardware.cpucores do
cpucores[i]=i
end

Do you still get the 'as a number' error message than ?

Strange that you get all those error messages while on my system I get no error message at all.

I will see if I can test my script with conky 1.10 as it complains about the top_right parameter in the conkyrc file. My guess is that it has something to do with a difference between conky versions.
