- # Clock Rings by Linux Mint (2012) reEdited by Altin.
- #
- # 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 324 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 in your conkyrc:
- #
- # lua_load ~/.conky/clock01_rings.lua
- # lua_draw_hook_pre clock_rings
- #
- # Changelog:
