I don't know if something like this already exists or if this even works for everyone.
I am using the Arduino software and often i just want to know if there is already a library for the thing i want to do,
if there is a new version of a library or just to download and install a library easily.
i made an application in C++ and wxWidgets to do exactly this.
It is using currently using 7zip for extracting the libs after download.
It was my first try in coding with wxWidgets and Gui development in C++ so i hope it is not too bad.
I only tested it on my windows machine and compiled it there, but i tried to only use things that are multiplatform compatible.
I put a quick and small webpage together here:http://ardulibrary.code-i.de/
The Sourcecode is in my SVN repository accessible with the username "gast":http://svn.code-i.de/ardulibrary/
a small Screenshot:
there are not all librarys in the list at the moment but it does not mean i like this more than the other libs.
The list is of course maintained by hand.
a doubleclick on a library sends you to the homepage of that lib.
