Ring Meters by londonali1010 (2009)
<< Modified by Crinos512 with inspiration from Proxess >>
<<< Modified some more by dmllerct >>>
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:
+ v1.3 -- Added color_background to set colors to background ring as opposed to indicator ring -dmillerct (24.11.2009)
+ 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)

-- 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='cpu',
-- "arg" is the argument to the stat type, e.g. if in Conky you would write ${cpu cpu0}, 'cpu0' would be the argument. If you would not use an argument in the Conky variable, use ''.
arg='cpu0',
-- "max" is the maximum value of the ring. If the Conky variable outputs a percentage, use 100.

-- "bg_colour" is the colour of the base ring.
bg_colour=0xFFFFFF,
-- "bg_alpha" is the alpha value of the base ring.
bg_alpha=0.0,
-- "fg_colour" is the colour of the indicator part of the ring.
fg_colour=0xFFFFFF,
-- "fg_alpha" is the alpha value of the indicator part of the ring.
fg_alpha=0.8,
-- "x" and "y" are the x and y coordinates of the centre of the ring, relative to the top left corner of the Conky window.

-- "radius" is the radius of the ring.
radius=87.5,
-- "thickness" is the thickness of the ring, centred around the radius.
thickness=15,
-- "start_angle" is the starting angle of the ring, in degrees, clockwise from top. Value can be either positive or negative.
start_angle=90,
-- "end_angle" is the ending angle of the ring, in degrees, clockwise from top. Value can be either positive or negative, but must be larger (e.g. more clockwise) than start_angle.
end_angle=450,
-- "color_coding" is the variable that defines if there's a colour state level
colour_coding=false,
-- "coding_direction" simply indicates if it's a countdown (false) or a status (true)
coding_direction=false,
-- "color_backgroud" is a true / false value to determie if the background ring is what recieves the color_coding value as opposed to the foreground ring

-- "warning" is the value that defines the state of the warning
warning=75,
-- "warning_colour" is the value that defines the state of the warning

-- "danger" is the value that defines the state of the danger
danger=85,
-- "danger_colour" is the value that defines the state of the danger
