-- Change these settings to affect your background:
-- "corner_r" is the radius, in pixels, of the rounded corners. If you don't want rounded corners, use 0.
corner_r = 50
-- Set the colour and transparency (alpha) of your background.

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.
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)

a lua script has a main function...the one that is called in your conky rc.. in this case its called "combined"
this is the function that conky runs each cycle...
when you amalgamate scripts you need to identify which bits to put into the main function and which functions are outside and being called by the main function...
