The Elementary OS is really powerful and beauty operation system, based on Ubuntu, and I want build programs for the OS. How can I start it? Any books, courses, step-by-step instructions etc? What do you can give advice to me for starting? I know the OS use Vala programming language, but I can't find any books for the one.
upd: Now I know on middle level CSS, HTML and PHP.
Thx for any answer, best

Start at the offical elementary website: https://elementary.io/docs/code/getting-started#getting-started
As stated by Florian Zwoch, the language of choice is Vala in combination with the GTK+ ("GUI-Framework").
Read https://chebizarro.gitbooks.io/the-vala-tutorial/content/ for a introduction to the Vala language itself.
Then go to Valadoc for a comprehesive documentation as well as some introduction turorials on the topic Vala in combination with GTK+ / Application development.
(Besides Vala, GTK+ has bindings for almost any language, with C/C++ and Python being the more popular)
Then you can look at the official Github repository and study the sources of the elementaryos apps: https://github.com/elementary
You find a few more helpful code examples on gnome.org: https://wiki.gnome.org/Projects/Vala/Examples
Valais some kind of modern language frontend forCprogramming, primarily for the GObject world (but not exclusively). That means for programing in the GNOME ecosystem.Not sure what you want to do - develop command line applications or graphical ones. For graphical ones you will want to learn the
Gtk+framework. It is based upon theGLibframework, which you would use if you want to create command line applications.I would recommend start reading on the
Gtk+documentation:https://developer.gnome.org/gtk3/3.22/
This is all in the
Cworld because the framework itself inC. So when usingValathings will be a bit different (but not too much). It can be challenging doing both at the same time - but it should be a good read and excercise to get a basic understanding on how things work.
