Conky with Lua

I am trying to use Conky, but I want to use lua with it. Lua is not compiled with conky when I use pacman. How do I solve this?

There is one in aur that has lau otherwise abs would be the way to go.

Memory Leakage in Conky with Lua

Hi there, I've been experiencing ongoing memory leakage using my Conky + Lua scripts. It tends to keep accumulating memory until I kill the process and restart it. Highest I've seen it go is 10% of my 4gb of RAM, so it does get to be substantial if unchecked.
I did google it, and it mentioned something about cairo_destroy(cr), so I inserted it at the end of functions randomly where it made sense (to my limited scripting skills) and where it didn't (just in case), but it didn't seem to make any difference.
Here is the lua script - it creates rings as % bars, I believe it was taken from somewhere on the arch forums months ago where it was also modified.
Ring Meters by londonali1010 (2009)
This script draws percentage meters as rings. It is fully customisable; all options are described in the script.
To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):

No I meant that the destroy functions should not be in conky_main at all. Why? Because you are using cr as an argument when you have no local cr defined. You are passing the undefined value (nil) to these destroy functions and they do nothing.
Like I said, I don't use conky or cairo but it is generally a good idea to destroy a resource you create. If you don't you will get memory leaks because "creating" is usually vague language that comes down to allocating memory and "destroy" deallocates memory.
This line from your own post creates a surface and stores it in the cs variable:
local cs=cairo_xlib_surface_create(conky_window.display,conky_window.drawable,conky_window.visual, conky_window.width,conky_window.height)
Yet you forget to deallocate the surface stored in cs. So add a line like this after each cairo_destroy(cr):
cairo_surface_destroy(cs)
I hope that helps.

[SOLVED] Error when compiling conky with audacious support

Edit: See post #8 for solution
Hello.
When trying to compile conky with the --enable-audacious option, I get the following error.
checking for Audacious... configure: error: Package requirements (audacious >= 1.4.0 audclient dbus-glib-1 glib-2.0 gobject-2.0) were not met:
No package 'audclient' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables Audacious_CFLAGS
and Audacious_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

My PKGBUILD is the one in the repos, with the addition of an --enable-audacious line. See below:

Using Conky with multiple MPD servers

Hello gang. I have 3 MPD servers that I connect to from my laptop (one is running on my laptop, 2 are on remote servers), and I'd like to have Conky report "now playing" info from whichever one is active at any given moment. My issue is with dynamically identifying the host/port within Conky.
I have a Python script that returns the host and port of the active MPD server, which is called like this:
$ python MpdInfoHandler.py -host
this.is.myhost
$ python MpdInfoHandler.py -port
6600
So, I tried putting this in my conkyrc:
mpd_host ${execi 300 python /pathtoscript/MpdInfoHandler.py -host}
mpd_port ${execi 300 python /pathtoscript/MpdInfoHandler.py -port}
This doesn't work - Conky seems to interpret the host and port as the actual strings appearing on each line. So, my question is: is there a way to assign the output of the script calls to "mpd_host" and "mpd_port"? Or does this only work when dealing with stuff underneath the "TEXT" section in conkyrc?
Thanks all

Conky with Gnome3 and dock plugin

Hi,
This is how my Conky looks like in Gnome3 with Gnome-Shell. I am using following preferences:
own_window_class Conky
own_window yes
own_window_type conky
own_window_transparent yes
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
While using dock, when application is maximized there is still a part of desktop background visible (the part of desktop above the Firefox icon on my screenshot). What I want to achieve is to use this spare space for conky.
I tried following configurations:
# Text alignment, other possible values are commented
alignment top_left
# Gap between borders of screen and text
gap_x 1500
and:
# Text alignment, other possible values are commented
alignment top_right
# Gap between borders of screen and text
gap_x -200
unfortunatelly none of above were working. Conky stays as shown on screenshot (even if I change the "gap_x" value to "2000" or "-500"). Any ideas how to move conky 50 pixels right?

Try commenting out own_window_hints.
When I moved to GNOME 3, I experienced the same problem, although my grip was the inability to use ctrl+alt+up/down if I stayed on an empty desktop with conky running.

Conky with a bash script

I am trying to change the color of my CPU temp text in conky to green, yellow or red based on the CPU temp. I am getting this in my conky:
Temperature: color green33
Here is my conky line:
${voffset 1}${goto 40}Temperature: ${font Droid Sans:style=Bold:size=8}${execpi 120 sensors | grep Core0 | paste -s | cut -c15-18 | xargs ~/.conky/colorize.sh}${hwmon 0 temp 1}°C${color}${font}${alignr}
Here is my bash script:
#!/bin/bash
# colorize.sh
COOL=65
WARM=80
if [[ $1 < $COOL ]];
then
echo "color green"
elif [[ $1 > $WARM ]];
then
echo "color red"
else
echo "color yellow"
fi
exit 0
Any help would be greatly appreciated.
Thanks

Using exec(p)(i) makes your conky run heavier, so, why wouldn't you use the built-in conky variables to achieve the same...
I'm using: (before "TEXT")
template2 ${color2}${if_match ${hwmon \1 temp \2}>75}${color orange}${if_match ${hwmon \1 temp \2}>90}${color red}${endif}${endif}${hwmon \1 temp \2}${color1}
and i call them like: (after "TEXT")
Temp ${template2 0 1}/${template2 1 1}/${template2 2 2}/${template2 2 4}
Of course you need to find out what numbers you need to pass to hwmon...

Help with LUA script

I need some help regarding the LUA scripting for the authentication of a vpn client. I am currently able to get the CN information from the certificate, but it comes in the form of last.first.middle.id#. what I need to do is write a script that isolates the id# which is a 10 digit number and then add a @mil to it. For instance if the certificate is returning ( smith.joe.chris.1111111111 ) I need to change that to 1111111111@mil. Thank you for your help in advance.

So all of this is just to set the column widths to the sizes pre-defined in a paragraph style, i.e., always the same?
I feel like I almost could do that in VB!
But in Javascript, all it needs is sth in the ilk of
var myWidths = [ 10, 50, 100, 50, 12 ]; // in whatever units you fancy
var myTable = app.activeDocument.stories[0].tables[0]; // (just grabbing some table)
for (i=0; i<myTable.columns.length; i++)
myTable.columns[i].width = myWidths[i % myWidths.length];
.. and the most interesting thing here (written from top of my head) is the "myWidths" lookup: it doesn't matter how many columns there are in this table, 'cause the widths array wraps around. (But you won't need this because you know all of your widths in advance.)

[Solved] Lua with Conky gives unwanted background color

Hi,
I've Googled and ransacked the forum looking for an answer. I have Conky with lua on KDE4 and I cannot run both together without creating an unwanted background. After getting sidetracked with KDE4 transparency considerations, I discovered that if I start Conky without Lua, I can get proper transparency. If I start Conky with Lua enabled I get a background color. The Lua script doesn't seem to have any background settings. I'm not sure what files are relevant to post, the conkyrc and or the Lua script, which is quite large. I'm reasonably au fait with Conky but this is the first Conky I cannot get to function correctly. My basic question is how to use Lua without starting a background color. Here is where I got the original files http://www.linuxandlife.com/2012/06/get … -your.html . Of course, I can post the relevant Lua file if necessary but, as I mentioned, it is quite large and I'm not clear on forum rules regarding posting large files of this type. Here's how Conky starts Lua:
lua_load ~/.conky/avi9526_conky.lua
lua_draw_hook_pre Widgets
Thanks for your time.
In case anyone is interested, changing line 1236 of the Lua script to cairo_set_source_rgba(CairoContext, 0.6, 0.61, 0.62, 0.0) did the trick.

If you set your minimum_size and maximum_width variables you can make it any size that you want.
So, lets say that you are using a 1280x1024 screensize.
You can set your minimum_size to be 1200. If you don't provide a second option, you are specifying the width.
Then, if you set your maximum_width to be 1280, or, if you want a 1 pixel gap on either side 1278, then your conky will not go off the sides of the screen, and if you use any align option, then it will stay within that specified width.
P.S. The reason that it doesn't go all the way across your screen right now, is because there is not enough information being displayed to warrant anything larger.

[SOLVED] Conky lua problem (transparency)

Hi,
I'm trying to transfer my conky from Ubuntu to Arch: below is a screenshot of the Ubuntu version (what it should look like). On Arch I have a solid black background. If it's relevant, I'm running Archbang rather than pure Arch, so with Openbox.
My main issue at the moment is the semi-transparency (and I'd like to have the rounded corners too). I understand that conky 1.8.0 can do transparency, but only with a compositor, and I'd rather keep my system as light as possible. So I've replaced my conky with 1.7.2 conky-lua from AUR and (don't know if this was necessary) installed cairo and lua from the repos. Unfortunately the lua script I used on Ubuntu isn't working; when I run conky in the terminal I get the message ".conkyrc: 121: config file error". At lines 120 and 121 I have my
lua_load ~/scripts/draw_bg.lua
lua_draw_hook_pre
My .conkyrc and lua script are below. Thanks for looking!

To call this script in Conky, use (assuming you have saved this script to ~/scripts/):
lua_load ~/scripts/draw_bg.lua
lua_draw_hook_pre
Changelog:
+ v1.0 -- Original release (07.10.2009)
-- Change these settings to affect your background.
-- "corner_r" is the radius, in pixels, of the rounded corners. If you don't want rounded corners, use 0.
corner_r=15
-- Set the colour and transparency (alpha) of your background.

The error in line 121 is because of lua_draw_hook_pre command must have a function name. In your file, it would be:
lua_draw_hook_pre draw_bg
To get the transparency put the command:
own_window_transparent yes
I have tried this in an AwesomeWM, with conky 1.8.0 compiled with lua support, and without compositing.

Sorry, I wanted to put code tags, but I was unaware of the command. I am running conky-lua-nv 1.8.0-1 from the AUR. There also seems to be some issue with the drawing of the rings, as it shows percents but not the graphical rings that go with it. I suspect it has something to do with the lua file. Anyone see any issue?

[SOLVED] Attempting to build conky-lua

Trying to get conky-1.9.0 to work with lua, got all the flags set so it does, but anytime I attempt to run make on it, It constantly gives me this error.

I'm decent with linux, rather new to Archlinux, so If anyone can give me a hand, I would appreciate it.

Conky-lua problem

I used this as a lua script guide for conky (semi-relvent)
error message I can't resolve with my current lua knowledge or though research/script reading.

Ive been trying to learn enough about lua and conky enough to make my own lua script for conky for flexabilty reasons. I want to be able to draw the background with lua which is what im trying to do here as a proof of concept.

I tried it. It had no effect. also I changed lua_draw_hook_post main to lua_draw_hook_post conky_main
and this is what i got. though i think its just annother error for the setting i just changed because its incorrect.

Shouldn't that be "Cairo" and not "Cario"?

[solved] Issue with conky and Kde 4

I have a small issue with conky and KDE 4.2. I start conky with a script which I stored under ~/.kde/Autostart. The script is simple and looks like this..
conky -c ~/.conkyrc_kde4
This works fine. But when I restart the first KDE and check with ps, I have 2 instances of conky running. The instances keep on growing with the number of restarts.
I think kde tries to restart all the apps which were running when the session was terminated. Is there a way to change this behavior in general or all the programs or for only a specific program like conky ?

I did
Systemsettings > Advanced > Session Manager > Start with an empty session
and put everything you want in Autostart

[SOLVED] Conky 100% transparent bg with Compiz

Enabling the Compiz Wallpaper (diffrent wallpaper at different desktop) with disabled nautilus/xfdesktop to draw on it..
How to make conky seems not to lose the transparency?

Hmm, I'm not too sure then. Have you tried asking in the compiz IRC channel? #compiz on freenode. Also these might be relevant:

Good luck!

Problem with Conky + Slim

Hello everyone!
I'm having an issue when running Conky with SLiM. Conky's background should be transparent, but on my desktop, instead of being transparent, shows a part of SLiM's background. I don't know how to fix this, could you help me??
Thanks in advance!

Hi everybody. I came across this post because conky was doing the same thing to me as to OP. I'm running SLiM and Xfce on top of Arch Linux PPC, and conky would show my underlying SLiM background instead of Xfce's when I wanted transparency. I tried all the solutions offered here without success, but fortunately I found another way.
What finally worked was enabling compositing in Xfce's Window Manager Tweaks dialog (Applications Menu --> Settings --> Window Manager Tweaks --> Compositor). I turned it on, fired up conky, and I got a beautiful, see-through conky showing my regular background. Woo!

I'd like to note that I needed own_window_type to be desktop. Setting to override shows the SLiM background again. Or maybe just a black background, I don't know. Anyway, choose desktop.
Just thought I'd share what worked for me, after hours of frustration.
