Conky Config Errors

duke11235 · 2010-08-24 02:34:24

I have conky installed and edited the file to "use" one I found on the thread,but I am having some difficuties adapting it and was wondering if someone could show me where I need to make changes for my Macbook 4,1.

Ring Meters by londonali1010 (2009)
 
This script draws percentage meters as rings. It is fully customisable; all options are described in the script.
 
IMPORTANT: if you are using the 'cpu' function, it will cause a segmentation fault if it tries to draw a ring straight away. The if statement on line 145 uses a delay to make sure that this doesn't happen. It calculates the length of the delay by the number of updates since Conky started. Generally, a value of 5s is long enough, so if you update Conky every 1s, use update_num > 5 in that if statement (the default). If you only update Conky every 2s, you should change it to update_num > 3; conversely if you update Conky every 0.5s, you should use update_num > 10. ALSO, if you change your Conky, is it best to use "killall conky; conky" to update it, otherwise the update_num will not be reset and you will get an error.
 
To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):
    lua_load ~/scripts/rings-v1.2.1.lua
    lua_draw_hook_pre ring_stats
 
Changelog:
+ v1.2.1 -- Fixed minor bug that caused script to crash if conky_parse() returns a nil value (20.10.2009)
+ v1.2 -- Added option for the ending angle of the rings (07.10.2009)
+ v1.1 -- Added options for the starting angle of the rings, and added the "max" variable, to allow for variables that output a numerical value rather than a percentage (29.09.2009)
+ v1.0 -- Original release (28.09.2009)

        for i in pairs(settings_table) do
            setup_rings(cr,settings_table)
        end
    end
end

The current problem is that it fails for battery life(I think), maybe network, and it doesn't draw the rings
Thanks guys

Which version of conky are you running? And it would be helpful if you posted the errors that you get when you start conky...

(And I edited your post to include code tags: please don't post long code excerpts).

I can't see the relevant area for battery life. If you can, try this.

Sorry, I wanted to put code tags, but I was unaware of the command. I am running conky-lua-nv 1.8.0-1 from the AUR. There also seems to be some issue with the drawing of the rings, as it shows percents but not the graphical rings that go with it. I suspect it has something to do with the lua file. Anyone see any issue?
