conky-draw

Easily create beautiful conky graphs and drawings.

The main idea is this: stop copying and pasting random code from the web to your monolithic conkyrc + something.lua. Start using a nicely defined set of visual elements, in a very clean config file, separated from the code that has the drawing logic. "You ask, conky_draw draws".

Examples

Simple disk usage.

{
    kind = 'bar_graph',
    conky_value = 'fs_used_perc /home/',
    from = {x = 0, y = 45},
    to = {x = 180, y = 45},
    background_thickness = 20,
    bar_thickness = 16,
},

Normal vs critical mode. You can even decide what changes when critical values are reached.

{
    kind = 'bar_graph',
    conky_value = 'fs_used_perc /home/',
    from = {x = 50, y = 120},
    to = {x = 120, y = 45},

    background_thickness = 5,
    background_color = 0x00E5FF,

    bar_thickness = 5,
    bar_color = 0x00E5FF,

    critical_threshold = 60,

    change_color_on_critical = true,
    change_thickness_on_critical = true,

    background_color_critical = 0xFFA0A0,
    background_thickness_critical = 10,

    bar_color_critical = 0xFF0000,
    bar_thickness_critical = 13
},

Everybody loves ring graphs in conky.

{
    kind = 'ring_graph',
    conky_value = 'fs_used_perc /home/',
    center = {x = 75, y = 100},
    radius = 30,
},

Lord of the customized rings.

{
    kind = 'ring_graph',
    conky_value = 'fs_used_perc /home/',
    center = {x = 75, y = 100},
    radius = 30,

    background_color = 0xFFFFFF,
    background_alpha = 1,
    background_thickness = 35,

    bar_color = 0x00E5FF,
    bar_alpha = 1,
    bar_thickness = 15,
},

Or even ring fragments.

{
    kind = 'ring_graph',
    conky_value = 'fs_used_perc /home/',
    center = {x = 75, y = 100},
    radius = 30,

    background_color = 0xFFFFFF,
    background_alpha = 0.7,
    background_thickness = 2,

    bar_color = 0xFFFFFF,
    bar_alpha = 1,
    bar_thickness = 6,

    start_angle = 140,
    end_angle = 300,
},

Right now you can define bar and ring graphs, and static lines and rings. Plans for the future:

Draw text elements (on arbitrary positions/areas, not like traditional conkyrc).
More basic elements: filled circles, rectangles, ...
Other more complex visual elements (example: clocks)

Installation

Copy both conky_draw.lua and conky_draw_config.lua to your .conky folder (your own conkyrc should be there too).
Include this in your conkyrc:

lua_load ./conky_draw.lua
lua_draw_hook_post main

or this if you are using conky 1.10 or newer:

conky.config = {
    -- (...)

    lua_load = 'conky_draw.lua',
    lua_draw_hook_pre = 'main',
};

Customize the conky_draw_config.lua file as you wish. You just need to add elements in the elements variable (examples above).
Be sure to run conky from inside your .conky folder. Example: cd .conky && conky -c conkyrc

Full list of available elements and their properties

Properties marked as required must be defined by you. The rest have default values, you can leave them undefined, or define them with the values you like.

But first, some general notions on the values of properties.

If the property is a...	This is what you should know
point	Its value should be something with x and y values. Example: `from = {x=100, y=100}`
color	Its value should be a color in hexa. Example (red): `color = 0xFF0000`
alpha level	Its value should be a transpacency level from 0 (fully transparent) to 1 (solid, no transpacency). Example: `alpha = 0.2`
angle	Its value should be expresed in degrees. Angle 0 is east, angle 90 is south, angle 180 is west, and angle 270 is north. Example: `start_angle = 90`
thickness	Its value should be the thickness in pixels. Example: `thickness = 5`
conky value	Its value should be a string of a conky value to use, and when used for graphs, should be something that yields a number. All the possible conky values are listed here. Example: `conky_value = 'upspeedf eth0'`
max value	It should be maximum possible value for the conky value used in a graph. It's needed to calculate the length of the bars in the graphs, so be sure it's correct (for cpu usage values it's 100, for network speeds it's your top speed, etc.). Example: `max_value = 100`
critical threshold	It should be the value at which the graph should change appearance. If you don't want that, just leave it equal to max_value to disable appearance changes. Example: `critical_threshold = 90`
boolean	It should be either true or false, with no quotes. Example: `change_color_on_critical = true`

Now, the elements and properties

line:

A simple straight line from point A to point B.
from (required)	A point where the line should start.
to (required)	A point where the line should end.
color	Color of the line.
alpha	Transpacency level of the line.
thickness	Thickness of the line.

bar_graph:

A bar graph, able to display a value from conky, and optionaly able to change appearance when the value hits a "critical" threshold. It's composed of two lines (rectangles), one for the background, and the other to represent the current value of the conky stat.
from (required)	A point where the bar graph should start.
to (required)	A point where the bar graph should end.
conky_value (required)	Conky value to use on the graph.
max_value and critical_threshold	For the conky value being used on the graph.
background_color, background_alpha and background_thickness	For the appearance of the background of the graph in normal conditions.
bar_color, bar_alpha and bar_thickness	For the appearance of the bar of the graph in normal conditions.
change_color_on_critical, change_alpha_on_critical and change_thickness_on_critical	Booleans to control wether the color, alpha and thickness of both background and bar changes when the critical value is reached.
background_color_critical, background_alpha_critical and background_thickness_critical	For the appearance of the background of the graph when the value is above critical threshold.
bar_color_critical, bar_alpha_critical and bar_thickness_critical	For the appearance of the bar of the graph when the value is above critical threshold.

ring:

A simple ring (can be a section of the ring too).
center (required)	The center point of the ring.
radius (required)	The radius of the ring.
color	Color of the ring.
alpha	Transpacency level of the ring.
thickness	Thickness of the ring.
start_angle	Angle at which the arc starts. Useful to limit the ring to just a section of the circle.
end_angle	Angle at which the arc ends. Useful to limit the ring to just a section of the circle.
Extra tip: start_angle and end_angle can be swapped, to produce oposite arcs. If you don't understand this, just try what happens with this two examples: `start_angle=90, end_angle=180` `start_angle=180, end_angle=90`

ring_graph:

A ring graph (can be a section of the ring too) able to display a value from conky, and optionaly able to change appearance when the value hits a "critical" threshold. It's composed of two rings, one for the background, and the other to represent the current value of the conky stat.
center (required)	The center point of the ring.
radius (required)	The radius of the ring.
conky_value (required)	Conky value to use on the graph.
max_value and critical_threshold	For the conky value being used on the graph.
background_color, background_alpha and background_thickness	For the appearance of the background of the graph in normal conditions.
bar_color, bar_alpha and bar_thickness	For the appearance of the bar of the graph in normal conditions.
change_color_on_critical, change_alpha_on_critical and change_thickness_on_critical	Booleans to control wether the color, alpha and thickness of both background and bar changes when the critical value is reached.
background_color_critical, background_alpha_critical and background_thickness_critical	For the appearance of the background of the graph when the value is above critical threshold.
bar_color_critical, bar_alpha_critical and bar_thickness_critical	For the appearance of the bar of the graph when the value is above critical threshold.
start_angle	Angle at which the arc starts. Useful to limit the ring to just a section of the circle.
end_angle	Angle at which the arc ends. Useful to limit the ring to just a section of the circle.
Extra tip: start_angle and end_angle can be swapped, to produce oposite arcs. If you don't understand this, just try what happens with this two examples: `start_angle=90, end_angle=180` `start_angle=180, end_angle=90`
