Re: Show us your conky

I've got two identical Lua mistakes in two Configurations from @wlourf

textLUAfehler.th.jpg textLUAfehler1.th.jpg bargrapLUAT500.th.jpg

The originals from 2010 are here:
https://wlourf.deviantart.com/art/Text- … -169288805
https://wlourf.deviantart.com/art/Bargr … -171334092

Has anyone seen this "triangular superimposition" and maybe a solution for me?

Thank you for your time.  smile

Use https://
It seems accuweather doesn't answer to curl calls over simple http anymore.
I'll force this in the script.

Re: Show us your conky

^ Thank you, loutch.

No, I don't have a chance. :8

I thought it was because of the writing "Japan", too.

But now I have found it, in both Conky's must be in the text.lua
to comment out the line (99). Then the display is correct. big_smile

		{
			text=conky_parse("${time %H:%M}"),

--			radial={0,-0,0,0,-80,70}        <---
		},

But I don't know anything about Lua.
I'm sure you know better than that.   wink

BARGRAPH WIDGET
v2.1 by wlourf (07 Jan. 2011)
this widget draws a bargraph with different effects 
http://u-scripts.blogspot.com/2010/07/bargraph-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.cairographics.org/samples/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 colours 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, parallel, 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 available 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
		    values 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"

Re: Show us your conky

Hello conky users,
I use the draw_bg.lua script since a while but I don't understand why few time ago it's no longer working, nothing is displaying on screen and I don't have any errors in the terminal... ? Does someone encounters this problem too with this script?
I circumvented the problem by using imagemagick and drawing semis-transparent backgrounds...

Re: Show us your conky

Hello ragamatrix,

I have no problems with the script. I'm running correctly in some distributions.
Maybe you have a simple mistake in the label:

draw_bg.lua
or
draw-bg.lua

no I think I correctly call the script that's the reason why I don't understand... but thx wink

With Sector11 we have tried this in conky1.10 and the "round corners" (per draw_bg.lua) already laboriously. We didn't succeed. It just didn't work and we had not found a solution in this conky-version.

excuse me   :8

my test with the
this one upstairs with "post" hook_post.th.pngwith "pre" hook_pre.th.png

and

I'm not sure, but the original lua-script should be "rewritten"....   big_smile

Re: Show us your conky

Recently a general question regarding conky popped in my mind:

Getting things like battery info or fan info grabs data from the root part of the system.

However when I edit conkyrc, I do not need sudo (i.e. root privileges).

Is there maybe a genaral explanation how conky gets root data without having root privileges?

You don't need to be root to read your system's /proc and /sys folders.

Look at your /sys/class/power_supply/BAT0 file, which has info about your battery; anyone can read it.

And I had an r_g_b error:

^ Yes, that's the same mistake I have and no solution.  sad

I have also studied intensively your link to Lua and conky1.10. Again, there is no hint for draw_bg.lua. Maybe it will come yet....
Here people in their spare time are struggling to regain their former condition in Conky!
What is significant is that with the introduction of Conky1.10, the simplicity of editing the configuration file has been lost.

Recently a general question regarding conky popped in my mind:

Getting things like battery info or fan info grabs data from the root part of the system.

However when I edit conkyrc, I do not need sudo (i.e. root privileges).

Is there maybe a genaral explanation how conky gets root data without having root privileges?

You don't need to be root to read your system's /proc and /sys folders.

Look at your /sys/class/power_supply/BAT0 file, which has info about your battery; anyone can read it.

Indeed, I can read those files in the BAT0 folder without sudo. I'm wondering why I needed sudo, when I tried to edit conkyrc on an ubuntu machine?
Also when I gave conkyrc from Bunsenlabs to users on different distros, without sudo it did not show all the data (e.g. not for fan speed, battery, etc.).

I can use the ragamarix draw_bg.lua in ascii with conky 1.10.6 adding a main function 

function conky_main()
    return ''
end

And using the same way to call the function as he does.
