« on: May 17, 2011, 03:21:26 PM »
can anyone please make a conky 1.8.1 extension?
the conkies in the repos are stripped down,
i want conky that supports xft, and lua with cairo bindings

..and I guess you'd like an extension for tolua also  ;)

..something to do with lua bindings for cairo.

We'll also need a shared lua lib, which doesn't appear to be in any of the extensions.

I've got conky to compile with lua bindings - just waiting to see what the lua extension maintainer would like to do about the shared lib.

It seems to be working now - I'll post it after some more testing.

Note:

1. I had to remove references in your configs to /media/sunny and 4 cpus  :P
2. Your config will only work with Xorg-7.5 and not Xvesa

Thanks for the script. I added it to my conky, plus I submitted conkyforecast to the repo.
