1. The is no such word as “Skup”.
2. There is no “Official” SketchUp Code Editor.
Instead, there are several 3rd party extensions, that are implemented in a web html dialog.
Unfortunately, the reality is that it is not Trimble’s responsibility to teach any kind of programming. Only to document their APIs.
I personally have spent many days and hours to compile lists of resources for novice SketchUp Ruby coders …
The list has links to free downloadable books on Ruby programming, as well as links to online blog posts and tutorials, many are SketchUp specific.
There are also a plethora of tutorials on the web for HTML, CSS, and JavaScript.
A forum is not really an adequate place to teach programming.
I am sorry that there is no way that we can “pour” the coding knowledge into novice brains.
Any person’s ability to absorb and apply new coding knowledge will depend upon their current foundation of the person’s programming knowledge.
This is why Steve asked you right away in the other topic on web dialogs …
… but you never really gave a good answer. So we didn’t have any good idea of your ability level.
So this basically makes me feel as though I’ve wasted two days of my time, when it comes to specifically helping you.
It is no one else’s responsibility but your own, to seek out and learn basic programming knowledge, so that when you ask questions, you are able to understand the answers.
I am not leaving. I am just not going to waste any more time giving advice that will not be used.
Hopefully other readers may find it useful.
