Hi,
I will create a GTK3-based application that creates Debian (*.deb) files. Once it is done, I will upload the src to my website (DCJTech.info), and then, I will share the link to the application. Thus, we can more easily generate *.deb files for Geany.
Is there any need to? We got Debian and Ubuntu packages a few minutes after the last the last release as we are in regular contact with the Debian and Ubuntu maintainers. Additionally, we have nightly builds available as Debian packages (http://nightly.geany.org/).
Are you missing anything?
By the way, sometime this week or next week, I will add the Squirrel filetype to the wiki.
Nice!
Regards, Enrico
