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) +]] + +settings_table = { + { + -- Edit this table to customise your rings. + -- You can create more rings simply by adding more elements to settings_table. + -- "name" is the type of stat to display; you can choose from 'cpu', 'memperc', 'fs_used_perc', 'battery_used_perc'. + name='time', + -- "arg" is the argument to the stat type, e.g. if in Conky you would write ${cpu cpu0}, 'cpu0' would be the argument.
