Post your .conkyrc files w/ screenshots

[VinDSL]

Heh! Speaking of commands...

Here's a cute one, for you:

killall -SIGUSR1 conky

Kills & reloads your .conkyrc in a single step.

That's cheating too...


EDIT

BTW, I changed exec to pre_exec, in the script (uses less resources).

[mrpeachy]

[QUOTE=42dorian;10844053]Yeah, I got bored and did some cleanup on my scripts. Including reducing the number.

@mrpeachy I found there were errors with the way you were doing the positive and negative arcs in a single script (Specifically every time it started it "Forgot" that some of the rings went counter-clockwise, and therefore needed to be "Told" by saving the script again before they would draw the right direction.) Fixed now. So... I kinda compiled everything I know (that you've taught me really) into reformatting the script entirely. It's a bit of a hack job right now, but it's all working. In case you wanted to see it.

end

if its working then its working but this doesn't seem a very efficient way of doing it
seeing as you have 2 separate function, one that draws positive and one that draws negative, you really dont need two main function called seperately in the conky rc

just copy all the setups and drawing function calls from function conky_draw_neg() into
function conky_draw_pos()

like so

function negative(x,y,z)
end

function positive(x,y,z)
end

function main
setup positive ring
x=x
y=y
z=z
call positive ring function
positive (x,y,z)

setup negative ring
x=x
y=y
z=z
negative (x,y,z)

end main function

you can also remove direction as a setting sent to the function as it no longer serves any purpose
i think its always a good idea to keep track of your variables and keep them in check

ive started putting lines like this at the end of the main functions

end-- if updates>5
cairo_destroy(cr)
cairo_surface_destroy(cs)
cr=nil
end-- end main function

a good idea borrowed from wlorfs scripts

and sometimes it is easier to draw rings without the need for functions at all, when you just need one or two

cairo_set_source_rgba (cr,0.5,0.5,0.5,1)
cairo_set_line_width (cr,14)
cairo_arc (cr,sx,sy,117,((math.pi)/180)*(92.5),((math.pi)/180)*(175))
cairo_stroke (cr)
root=conky_parse("${fs_used_perc /}")
cairo_set_source_rgba (cr,102/255,122/255,119/255,1)
cairo_arc_negative (cr,sx,sy,117,((math.pi)/180)*(175),((math.pi)/180)*(175-((82.5)*(root/100))))
cairo_stroke (cr)

for example
sx and sy are defined elsewhere in the script

understanding what the numbers mean in the various cairo commands is extremely important

[Abdus]

I just reinstalled my system, so some specs changed, and obviously I also went for a new, fresh look. This brought a need for a semi-transparent conky background.

I used the conky+compiz method to get it semi transparnt, but the effect is BAD: everything in conky is semitransparent now, including text, pictures and graphs, and I want only the background transparent.

Any tips?

[42dorian]

Oh... sorry mrpeachy... I don't mean YOU were doing it wrong, I mean that I was getting errors when it ran the old way. It wasn't drawing the negative rings in the negative when I first started it, so I had to save the script before it would draw them properly. And now it draws them perfectly every time.

I'm quite aware of the massive inefficiency of the code as it is. But, it works for me, and I actually understand enough of it that I can fix it if it breaks (to a degree.) and I still don't quite get what you just told me. I am, by far, not your best student. Thank You though! Ultimately I only brought it to your attention in case you got offended that I wedged the netring in the way I did.

I kinda get the surface destroy at the end of the function part though. I think I might add that eventually.

if i post some code on a forum then people can do whatever they want with it and i wont get offended

unfortunately i don't have the original script to test, as i would like to find out what was going on for future reference

you arent the first person who has tried a script i wrote that didnt work, and upon later inspection turned out it was a mistake in the script by me causing the problem

Hi Degan
I just posted an updated version of this script here
http://crunchbanglinux.org/forums/post/123465/#p123465

take a look and see if that script works for you

the whole sun moon concept is still a work in progress

[mrpeachy]

Anyone have an idea of how I could set up conky to show my current user-agent?

do you use more than 1 browser?
this site tells you your user-agent
http://whatsmyuseragent.com/

but the problem is you cant use curl to access the site because then the user-agent is curl and not your browser

i wrote a lua script that lets conky display open windows and identify the active window
http://crunchbanglinux.org/forums/post/121198/#p121198

if you have more than one type of browser open then you could identify which was active and then display info from whatismyuseragent

but i cant think of any simple way

[VinDSL]

but i cant think of any simple way

I can't either.

Too bad we can't prompt the browser to run this from the addy bar:

javascript:alert(navigator.userAgent);

...and write the output to a text file.
