Conky v1.9 Thread

Gordon · 2013-03-09 10:15:56

Hi Folks

well I have got rid of the warning

WARNING: gnome-keyring:: couldn't connect to: /home/gordon/.cache/keyring-f9X7

by coping an existing basic conky that comes with the distro but won't mark this as solved as I have no idea what caused it.

still no luck with the lua script though but I will keep trying

lionhead · 2013-03-09 10:32:01

i have a little problem. i would like to display the status of the weather from this webpage:

if they show a specific image they display a special text, for example:

http://www.gco.org.au/weather/clearsky.gif ---> shows the word: clear

this is the code from their wegpage:

<SCRIPT LANGUAGE="JavaScript">
var boltwood='1'
var icon
var bolttext 
if (boltwood == 0)
{icon = 'unknownsky.gif';bolttext='Unknown'}
else if (boltwood == 1)
{icon = 'clearsky.gif';bolttext='Clear'}
else if (boltwood == 2)
{icon = 'partcloudsky.gif';bolttext='Partly Cloudy'}
else if (boltwood == 3)
{icon = 'cloudsky.gif';bolttext='Very Cloudy'}
else if (boltwood == 4)
{icon = 'rainsky.gif';bolttext='Raining'}
document.write('<BR> <ALIGN=CENTER><IMG SRC=\"' + icon + '\" BORDER=0><BR>');
document.write('<ALIGN=CENTER><B><font color="yellow" face="Arial" size="2">' + bolttext + '</P></B>');
</SCRIPT>

</SCRIPT>

So, it's that "boltwood" variable is changing, rest is static.
Then you can hardwire your own table with both icon and text depending on this variable and search for this variable value only:

 --[[

 	default interval=3600 of conky updates (1h if conky_updates=1)

 		lua_draw_hook_pre conky_sunriseset
 
 	set custom interval=4000 of conky updates (1h 10m if conky_updates=1)
 		lua_load $HOME/path-to-script/sunriseset.lua
 		lua_draw_hook_pre conky_sunriseset 4000
 --]]

 local function fetch_weather(updates, interval)
 	if startup then if (updates % interval) ~= 0 then return "100" end else startup=true end
 	os.execute("wget -q "..file_uri.." -O "..file.." &")
 end
 
 local function fetch_file(fw, updates, interval)
 	if ( fw ~= "100" and fTab[1] ~= nil ) or (updates % interval) ~= 0 then return "" end
 	i=0
 	local f=io.open(file, 'r')
 	if f then io.close(f) else return "200" end
 	for line in io.lines(file) do
 		i=i+1
 		fTab[i]=line
 	end
 end
 
 local function parse_table(ff)
 	if ff == "200" or fTab[1] == nil then return "300" end
 	local t, i, k, v = {}, 0, nil
 	for k, v in pairs(fTab) do
 		if string.find(v, ">Sunrise") then
 			for k in string.gmatch(v, "%d%d:%d%d:%d%d") do i=i+1; t[i]=k end
 		end
 		if string.find(v, "var boltwood") then t[0]=string.gsub(v, ".*(%d).*", "%1") end

 end
 
 function conky_sunriseset(interval)
 	if conky_window == nil then return "0" end
 	local updates=tonumber(conky_parse('${updates}'))
 	if updates <= 5 then return "0" end
 	if not interval or tonumber(interval) < 3600 then interval=def_interval else interval=tonumber(interval) end
 	
 	fw=fetch_weather(updates, interval)
 	ff=fetch_file(fw, updates, 15)
 	pt, sunrise, sunset, weatherNo = parse_table(ff)
 	if not sunrise or pt == "300" then sunrise=def_sunrise end
 	if not sunset or pt == "300" then sunset=def_sunset end
 	if not weatherNo then weatherNo=1 else weatherNo=tonumber(weatherNo)+1 end

 end

Just a thought - maybe you've picked up on this already:

-- ####################################
ptint ('hello world')
-- ####################################

ptint = print <<-- I do the same all the time

I figure since I already posted the code when I was looking for help, I should just show what my new lua project looks like so far.

so here is your sneak preview.

I think once I have finished making it, that I want to make it into an interactive conky... maybe, we shall see.

VastOne · 2013-03-09 18:55:41

Very nice ansem_of_nexus!

Reminds me of an xBox controller...

Where do I find the keyring mentioned or do I just go to the .cashe and make it ?

This is only a warning message and won't cause any problems if you ignore it.

You have to run

/usr/bin/gnome-keyring-daemon --start --components=pkcs11

with your window managers "run command at login" function to get rid of that warning.
There are more options that may need to be added to the "--components=" section (as a comma separated list) if you use programs that need them but conky wants the "pkcs11" option.

Gordon · 2013-03-10 11:16:45

Hi Folks,

Thanks for your help

@ Sector11,

Thanks for that but just for once I had actuall spotted that typo

@ arclance,

Thanks for the info. Not sure that I understand what you are saying when you say windows manager. Do you mean slim and if so how do I add that command or is it in oopenbox that it has to go ?

Sector11 · 2013-03-10 14:08:29

@ Gordon ...

OpenBox is the Window Manager of choice in #!

Probably need to put that command in ~/.config/openbox/autostart

Personally, I just deleted the keyring, I don't need it.

arclance · 2013-03-10 14:49:39

^ I believe that is correct for openbox but it needs to be

/usr/bin/gnome-keyring-daemon --start --components=pkcs11 &

if your window manager uses a startup script.

Gordon · 2013-03-10 15:54:10

Hi arclance,

Thanks for the quick reply.

I have just opened openbox autostart and that line is already inserted, still not to worry as it causes no problems I'll just ignore it in future.

Next question if I can tag it on Iget this

Conky: llua_load: /home/gordon/lua/GordonsScripts/hello:5: '=' expected near 'yes'

I have nothing in the script that has a yes near it what is that about please ?

Post your whole "~/.config/openbox/autostart" file to see if there is anything that could cause it not to work in there.

I would need to see your script as it is now to help you with that.

Naik · 2013-03-10 23:27:18

Hey! i used the wallbydesk-script (thanks to ragamatrix) and non-sticky conkys to build kind of an command center on first desktop:

yes, for me there is a slight delay when switching desktops but only in combination with conky, which means the bg of the conkys changes about half a sec later than the rest, but this is not much of a problem and the mem-usage in idle increased by 2mb.
next step is to make the bottom-right conky clicky (i d love to only show the fs_bars on click) and to place a quarter ring launcher in the bottom left.

@ansem_of_nexus: love your new projekt!

@ all: thanks for all the knowladge and inspiration!

This is wrong you can't call each component argument separately like that.
I think this was a error in a old version of #! when things were being tried to get rid of the "gnome-keyring" warning.
The correct command would be like this.

I don't know if you need the

/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 && \

line or not in Openbox but I don't need it with Fluxbox.

All of this belongs in your .conkyrc not your Lua script, they are separate files.

You load the lua script with "lua_load" in your .conkyrc and run it with "lua_draw_hook_pre" or "lua_draw_hook_post" most of the time.
There are other commands to run a script with but they are for more specialized scripts than the one you are working on.
You can find the documentation on those settings here.

Gordon · 2013-03-12 18:06:34

Hi arclance

Thanks for that. I will try all that out later, poss tomorrow, going out now for the night with the ball and chain for a meal etc.
will let you know how it all goes later on

Gordon · 2013-03-13 18:39:37

Hi arclance,

Well I have got there in the end. It is now working. I managed to find a couple of mistakes that I had made

The first one was I had pointed lua_draw_hook_pre to the wrong place / item ( main_box instead of conky_main ) in .conkyrc

The second one was a complete mess up of ' if updates ' which I had jumbled up with ' local updates '. All put ito one line of nothingness

Anyway thanks for all your time and efforts to sort me out without which I doubt that I would have got anywhere at all

THANK YOU

i made a function that displays several variables in conky and adds automatically custom endings.

the most variables that shows the unit 'percent' have the word 'perc' or 'percent within the name of the variable, for example

memperc

the variable 'cpu' also displays the unit % the problem is that this word doesn't use the word 'perc'. but there are also other variables that contain the word 'cpu' within, for example cpugauge

when i use this then it wont work

string.find(conky_variable, "cpu")~= nil

do u have an idea how i fix this?

ansem_of_nexus · 2013-03-14 16:15:33

happy pi day

So I was wondering if anyone had tested out the Conky GUI editor, to find out if it is any good?

dunno how you use it but this snippet works for me in LUA terminal:

test="acpugauge"; if string.find(test, "cpu") then print("it is") else print("it is not") end

@ansem_of_nexus:
I tryed to, but recently i can`t get it to work...

edit: as for my last post: is there by any means a chance to wrap the output of the conky to the surface of the tablet? maybe with lua?
