OK

I have got my deg variable recognized as wetter[11] will add the other three as 12-14.



Safari, Sogoodi!

[Logansfury]

Bleys can you please help me with a conversion script?

I got this to convert wind degrees number into an alphabetic direction

Code: Select all

${execpi 3600 echo "$(awk 'BEGIN{dir[1]="N";dir[2]="NE";dir[3]="E";dir[4]="SE";dir[5]="S";dir[6]="SW";dir[7]="W";dir[8]="NW";for(i in dir) if(i*45-45<$wetter[10] && $wetter[10]<=i*45) print dir[i]}')"}

How could I use this in the script to apply the outcome of above to a variable I could then print onscreen along with the degree number. I would like degree and direction to both display please.

[Bleys]

Bleys can you please help me with a conversion script?

this is much easier and more elegant to implement. wetter.lua, add 2 Lines after the fDrawImage line:

Code: Select all

	        local arc_deg = (2 * math.pi / 360) * wetter[11]
                fDrawImage(cr,home_path..'/.conky/wettericons/arrow.png',76,80,16,16,arc_deg)

find an arrow that suits you, name is arrow.png and place it inside Weather Icon Folder. I made a simple one with gimp:

arrow.png (1.79 KiB) Viewed 442 times

Screen Capture_select-area_20240207222640.jpg (12.92 KiB) Viewed 442 times

Do not forget: As with placing, fDrawImage rotates images around the center of the image.

This does look nice, but I was hoping to get an alphabetical readout following the degrees display, such as:

Code: Select all

Wind Dir: 90° E

Koentje had a great idea, have conky launch a bash script that prints the outcome of the script to a text document, then have conky read the text document and display the result. His forte is bash however, could you please help me compose this for .lua?

[Koentje]

Koentje had a great idea, have conky launch a bash script that prints the outcome of the script to a text document, then have conky read the text document and display the result.

You're worse at explaining what you want. You said that the bash script was started by something else, not by conky. If i knew it was started by conky, then you didn't have to save it to a text file first, but just echo it to the terminal and execute the script with ${execp script}. P for PASTE output to conky.

[Logansfury]

You're worse at explaining what you want.

Probably an Italian-American thing >.<

Plus pulling all nighters, my mind is a void sometimes.

Lemme see how much of this I can pull off without needing help formatting.

Actually I am already at a loss. I have a terminal style script to convert degrees to direction, How do I get the conky variable wetter[11]'s contents run by the script?

I have two conversion scripts to work with:

Code: Select all

wetter[11]=$(awk 'BEGIN{dir[1]="N";dir[2]="NE";dir[3]="E";dir[4]="SE";dir[5]="S";dir[6]="SW";dir[7]="W";dir[8]="NW";for(i in dir) if(i*45-45<$1 && $1<=i*45) print dir[i]}')

Code: Select all

-- degrees to direction
${execpi 3600 echo "$(awk 'BEGIN{dir[1]="N";dir[2]="NE";dir[3]="E";dir[4]="SE";dir[5]="S";dir[6]="SW";dir[7]="W";dir[8]="NW";for(i in dir) if(i*45-45<$wetter[11] && $wetter[11]<=i*45) print dir[i]}')"}

Have a wonderful evening Bleys! That compass image is beautiful!!

If I can manage to get the alphabetic conversion done, I think I would like to use that on one linux box, and the compass you just displayed on my 2nd box

Perhaps tomorrow you can set me up with that image file?

Take care

[Bleys]

Ok.. I probably wouldn't have had any peace of mind until I had a solution. So then, without much description. Everything that generates the output is outlined in red.

Addition: To cover N (North) right add this line:

Code: Select all

                if dir==17 then dir = 1 end

bevor the last write_text

[Logansfury]

Coming along nicely. I am working with a pair of these, One closer to original for comparison:

[Bleys]

Ups.. The arrow must be reversed. This way it points in the direction from which the wind is coming. Just rotate the Arrow 180°

You are like unto a forum GOD That is exactly what I wanted thank you! I do also very much like your compass art and would like to have that sometime tomorrow for linux box #2

I wish you well-deserved rest

[Logansfury]

It looks awesome to me! The arrow is pointing to SW so I'm happy. When I swapped it pointed to NE (Yes I am keeping your awesome arrow )

[Logansfury]

I have 2 versions of your weather conky prepared. One to possibly go in my Minimalis, the other for the other linux box, which I have formatted to make room for the compass artwork.

[Logansfury]

Hey Bleys,

When you have time please look at this. I noted in my wetter.lua that the update symbol in your conky was displaying like a rectangle with symbols in it. I went to your site with the original weather only documents, and noted you had Font Awesome as the font for that symbol. I found a font awesome download, and it has files full of symbols, but when I open it in gimp and type out its only alpha-numeric chars. Then I noticed that after loading the font, my display in text editor of wetter.lua showed the same 90 degree turning arrows forming a box as you had in your first conky pictures! However, while I have this update symbol in the .lua, it is NOT showing on the widget. Note the image below with arrows pointing to the pertinent items. Do you know what I need to do to get conky to display like my text editor does?



Here is how it showed before I installed the font:

[Logansfury]

I just saw something else intriguing in your work! In this conky:


I note a sunrise font symbol by the 08:23 time and a sunset font symbol next to 17:03 time.

May I have the font for those please?

I am currently traveling with my Notbook. The Compass picture will come this afternoon.

Got em! Thank you so much! What about the Font Awesome? I downloaded one that corrected the output and showed the flowing arrows in the .lua but its still displaying as a blank rectangle on screen
