-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 near the end of the script 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/clock_rings-v1.1.1.lua
- lua_draw_hook_pre clock_rings
-
-Changelog:
-+ v1.1.1 -- Fixed minor bug that caused the script to crash if conky_parse() returns a nil value (20.10.2009)
-+ v1.1 -- Added colour option for clock hands (07.10.2009)
-+ v1.0 -- Original release (30.09.2009)
