1 --[[  2 Clock Rings by londonali1010 (2009) Edited by jpope  3   4 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.  5   6 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.  7   8 To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):  9     lua_load ~/scripts/clock_rings.lua 10     lua_draw_hook_pre clock_rings 11      12 Changelog: 13 + v1.0 -- Original release (30.09.2009) 14    v1.1p -- Jpope edit (05.10.2009) 15 modified by putputput (13.10.2010v0.01£»14.10.2010v0.02) 16 ]] 17  18 settings_table = { 19     { 20         -- Edit this table to customise your rings. 21         -- You can create more rings simply by adding more elements to settings_table. 22         -- "name" is the type of stat to display; you can choose from ‘cpu‘, ‘memperc‘, ‘fs_used_perc‘, ‘battery_used_perc‘. 23         name=‘time‘, 24         -- "arg" is the argument to the stat type, e.g. if in Conky you would write ${cpu cpu0}, ‘cpu0‘ would be the argument.
