Clock Rings by londonali1010 (2009)
This script draws percentage meters as rings, and also draws clock hands if you want! It is fully customisable; all options are described in the script. This script is based off a combination of my clock.lua script and my rings.lua 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.
Clock Rings Mod by Proxess (2009)
This modification permits you to add warning colours on both countdown values (batteries, wlan, etc) and status percentages (cpu, file system usage, etc).
To call this script in Conky, use the following (assuming that you save this script to ~/.conkygui/scripts/clock_mod.lua):
lua_load ~/.conkygui/scripts/clock_mod.lua
lua_draw_hook_pre clock_rings

And yeah, the more time you spend on this thread, the more often you tear up your Conky.
