Reading vt100 docs/relying on nim's terminal is not enough, it's best to test everything out there. Different terminal emulators, a few different OS'es or distros and also windows specific emulators.

Unless otherwise specified, everything falls back to Artix linux (basically the same versions of software as arch), x86_64, nim 1.4.2.

Notes on 26.2.2021

Found issues

  • (minor, doesn't affect repls) examples/editor does not scroll to the end right after opening when opening a file too large to fit in the screen.

  • (minor) examples/interactive_history when a history element is taller than the screen, it can cause issues with the rendering of the next history element when scrolling through history

tmux notes

  • ctrl+pageup and ctrl+page down do not create any input (not even for getch)
  • otherwise pass

tty notes

  • ctrl+(arrow keys) does not create a distinct key

powershell notes

  • editor issues:
  • on horizontal scroll conditions the line can overflow causing rendering bugs
  • on vertical scroll + page up the first line could disappear (maybe only when first line is a horizontal scroll candidate)
  • very slow experience, a lot of cursor jumping

cmd.exe notes

  • same issues as powershell
