Thank you so much, Erel!
This is very instructive for the lesson.

Is there an opportunity to see the compiler itself, and the dialog shell (IDE)?
What are they written on?

Accidentally not on .Net?

thank

Anything else not in the Github repository is not open source. The IDE is based on .Net Framework.
