Console Capability Tests
Raw
README.md

These is a basic console capability test. Clone this repo (https://gist.github.com/58553b13c477de79069e.git) and use node cat console-test.txt to dump the test to your screen. (On Mac & Linux you can just use cat.) There's also a hide-cursor.txt and show-cursor.txt that should do what they say.

All of this is about me trying to figure out what actually is shared cross platform and what isn't.

What I've learned so far is:

  • Windows & OSX both support cursor controls (to my surprise!)
  • Windows does not support italics or underline (no surprise)
  • Examining of Windows behaving around positioning ^[[1;1H and screen clearing ^[[J, seems to imply that it treats the line the program started on as 1,1 for positioning purposes and there's no way to position above your starting line.
  • Region scroll events are not supported on Windows.

Output on different terminals:

OSX Terminal (uncustomized)

Uncustomized Terminal.app

iTerm2 (customized colors)

Windows cmd.exe

Interesting! I would probably throw cmder in the mix for Windows terminals - most "devs on Windows" that I know use it. If I had a Windows environment immediately available, I'd go ahead and run these tests myself. :P
