--[[ 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. To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua): lua_load ~/scripts/rings-v1.2.1.lua lua_draw_hook_pre ring_stats Changelog: + v1.2.2 -- Converted to one4all module by dk75 (03.2012) + 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) ]] local modname = ... local M = {} _G[modname] = M package.loaded[modname] = M --[[ ############################################################################### ### SETTINGS ### ############################################################################### --]] local 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'. -- If you set it to nil value then base ring only will be drawn. 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.
