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.lua
lua_draw_hook_pre ring_stats
Changelog:
+ 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)

--[[ BARGRAPH WIDGET
v2.1 by wlourf (07 Jan. 2011)
this widget draws a bargraph with different effects
http://u-scripts.blo...aph-widget.html
To call the script in a conky, use, before TEXT
lua_load /path/to/the/script/bargraph.lua
lua_draw_hook_pre main_rings
and add one line (blank or not) after TEXT
Parameters are :
3 parameters are mandatory
name - the name of the conky variable to display, for example for {$cpu cpu0}, just write name="cpu"
arg - the argument of the above variable, for example for {$cpu cpu0}, just write arg="cpu0"
arg can be a numerical value if name=""
max - the maximum value the above variable can reach, for example, for {$cpu cpu0}, just write max=100
Optional parameters:
x,y - coordinates of the starting point of the bar, default = middle of the conky window
cap - end of cap line, ossibles values are r,b,s (for round, butt, square), default="b"
http://www.cairograp...s/set_line_cap/
angle - angle of rotation of the bar in degress, default = 0 (i.e. a vertical bar)
set to 90 for an horizontal bar
skew_x - skew bar around x axis, default = 0
skew_y - skew bar around y axis, default = 0
blocks - number of blocks to display for a bar (values >0) , default= 10
height - height of a block, default=10 pixels
width - width of a block, default=20 pixels
space - space between 2 blocks, default=2 pixels
angle_bar - this angle is used to draw a bar on a circular way (ok, this is no more a bar !) default=0
radius - for cicular bars, internal radius, default=0
with radius, parameter width has no more effect.
Colours below are defined into braces {colour in hexadecimal, alpha}
fg_colour - colour of a block ON, default= {0x00FF00,1}
bg_colour - colour of a block OFF, default = {0x00FF00,0.5}
alarm - threshold, values after this threshold will use alarm_colour colour , default=max
alarm_colour - colour of a block greater than alarm, default=fg_colour
smooth - (true or false), create a gradient from fg_colour to bg_colour, default=false
mid_colour - colours to add to gradient, with this syntax {position into the gradient (0 to1), colour hexa, alpha}
for example, this table {{0.25,0xff0000,1},{0.5,0x00ff00,1},{0.75,0x0000ff,1}} will add
3 colurs to gradient created by fg_colour and alarm_colour, default=no mid_colour
led_effect - add LED effects to each block, default=no led_effect
if smooth=true, led_effect is not used
possibles values : "r","a","e" for radial, parallelel, perdendicular to the bar (just try!)
led_effect has to be used with theses colours :
fg_led - middle colour of a block ON, default = fg_colour
bg_led - middle colour of a block OFF, default = bg_colour
alarm_led - middle colour of a block > ALARM, default = alarm_colour
reflection parameters, not avaimable for circular bars
reflection_alpha - add a reflection effect (values from 0 to 1) default = 0 = no reflection
other values = starting opacity
reflection_scale - scale of the reflection (default = 1 = height of text)
reflection_length - length of reflection, define where the opacity will be set to zero
calues from 0 to 1, default =1
reflection - position of reflection, relative to a vertical bar, default="b"
possibles values are : "b","t","l","r" for bottom, top, left, right
draw_me - if set to false, text is not drawn (default = true or 1)
it can be used with a conky string, if the string returns 1, the text is drawn :
example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
v1.0 (10 Feb. 2010) original release
v1.1 (13 Feb. 2010) numeric values can be passed instead conky stats with parameters name="", arg = numeric_value
v1.2 (28 Feb. 2010) just renamed the widget to bargraph
v1.3 (03 Mar. 2010) added parameters radius & angle_bar to draw the bar in a circular way
v2.0 (12 Jul. 2010) rewrite script + add reflection effects and parameters are now set into tables
v2.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"

--[[ GRAPH widget v1.1 by wlourf (07.01.2011)
this widget draws some graphs with some effects
http://u-scripts.blo...aph-widget.html
To call the script in a conky, use, before TEXT
lua_load /path/to/the/script/graph.lua
lua_draw_hook_pre main_graph
and add one line (blank or not) after TEXT
Parameters are :
3 parameters are mandatory
name - the name of the conky variable to display,
for example for {$cpu cpu0}, just write name="cpu"
arg - the argument of the above variable,
for example for {$cpu cpu1}, just write arg="cpu1"
arg can be a numerical value if name=""
max - the maximum value the above variable can reach,
for example for {$cpu cpu1}, just write max=100 or less or more
Optional parameters:
x,y - coordinates of the bottom-left corner of the graph,
relative to the top-left corner of the conky window
default = bottom-left corner of the conky window
width - width of the graph, default = 100 pixels
height - height of the graph, default = 20 pixels
nb_values - number of values to display in the graph, default=width
i.e. 1 pixel for 1 value
autoscale - if set to true, calculate the max valeu of the y axis and
doesn't use the max parameter above, default=false
skew_x - skew graph around x axis, défaut = 0
skew_y - skew graph around y axis, défaut = 0
angle - angle of rotation of the graph in degress, default = 0
i.e. a horizontal graph)
inverse - if set to true, graph are draw from right to left, default=false
background - if set to false, background is not drawn, default=true
foreground - if set to false, foreground is not drawn, default=true
foreground = plain graph
bg_bd_size - size of the border of the background, default=0=no border
fg_bd_size - size of the border of the foreground, default=0=no border
Colours tables below are defined into braces :
{position in the gradient (0 to 1), colour in hexadecimal, alpha (0 to 1)}
example for a single colour table :
{{0,0xFFAA00,1}} position parameter doesn't matter
example for a two-colours table :
{{0,0xFFAA00,1},{1,0x00AA00,1}} or {{0.5,0xFFAA00,1},{1,0x00AA00,1}}
example for a three-colours table :
{{0,0xFFAA00,1},{0.5,0xFF0000,1},{1,0x00AA00,1}}
bg_colour - colour table for background,
default = {{0,0x000000,.5},{1,0xFFFFFF,.5}}
fg_colour - colour table for foreground,
default = {{0,0x00FFFF,1},{1,0x0000FF,1}}
bg_bd_colour- colour table for background border,
default = {{1,0xFFFFFF,1}}
fg_bd_colour- colour table for foreground border,
default = {{1,0xFFFF00,1}}
bg_orientation, bg_bd_orientation, fg_orientation, fg_bd_orientation,
- "orientation" defines the starting point of the gradient,
default="nn"
there are 8 available starting points :
"nw","nn","ne","ee","se","ss","sw","ww"
(n for north, w for west ...)
theses 8 points are the 4 corners + the 4 middles of graph
so a gradient "nn" will go from "nn" to "ss"
a gradient "nw" will go from "nw" to "se"
draw_me - if set to false, graph is not drawn (default = true)
it can be used with a conky string, if the string returns 1, the graph is drawn :
example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
v1.0 (31/10/2010) original release
v1.1 (07/01/2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"
