Geniunely curious, how projects like these get approved in an org at the scale of Microsoft? Is this like a side project by some devs or part of some product roadmap? How did they convince the leadership to spend time on this?
As they explained, they needed a text editor that works in a command line (for Windows Core server installs), works across SSH (because for a while now Windows included an SSH Server so you can completely manage it through SSH), and can be used by non-vi-experienced Windows administrators (i.e. a modeless editor).
This is not a rewrite. Maybe it’s slightly inspired by the old thing, especially with having GUI-style clickable menus (something not seen often in terminal editors), but it’s much more modern.
