Why is your project not so well-known?

vtm is just starting to become usable. Until recently, it was just a demo. But even now it has several serious drawbacks that do not allow it to be used in production:

  • Built-in terminal is very memory hungry. But his greed can be tempered by about 30 times, See #147
  • Built-in terminal can only run in main process space, not as a standalone process, and memory is not reallocated when it is closed, See #148
  • Cannot be operated with keyboard only, See #86

How did you learn things like this

Many different subjects

  • Unicode Standard (latest), About the Unicode. It is important to read it and understand it. It is one of the fundamental things.
  • Character encodings in particular UTF-8, but also historical encodings you need to know to understand the subject.
  • Font technologies are also fundamental. Font and Computer font. A comprehensive description of this technology can be found in the FontForge documentation. There is also a lot of information about fonts in the various SDK documentation, for example Win32 Fonts.
  • Writing systems. Writing systems list for understanding key principles:
  • History and principles of operation of terminals, as well as many IT-standards associated with it.
  • Basic knowledge of operating systems POSIX(Unix) and Microsoft Windows (Win32).
  • Some knowledge of Algebra and Mathematical analysis (mainly for video FX, but not only).
  • Well, programming itself.
