perform console initialization in windows

[dankamongmen]

Elements of this are alluded to in #2014. There are a few termios-like functions we need to call in Windows during initialization.

• SetConsoleMode() https://docs.microsoft.com/en-us/windows/console/setconsolemode
  • ENABLE_PROCESSED_OUTPUT, ENABLE_VIRTUAL_TERMINAL_PROCESSING, ENABLE_WINDOW_INPUT, ENABLE_MOUSE_INPUT all look relevant
• See catch resize events on windows #1961 regarding use of GetConsoleScreenBufferInfo() for screen geometry

it looks like we can disable line discipline events with ENABLE_PROCESSED_INPUT, enter cbreak mode with ENABLE_LINE_INPUT, and disable echo (see #2019) with ENABLE_ECHO_INPUT

Do try to do things the VT way as much as possible. Some of those things like GetConsoleScreenBufferInfo() are Win32 API, not VT. I'm sure a mix of sorts is needed in the case of a library like this but ideally there's a way to find the VT equivalent within the OpenConsole code over at https://github.com/microsoft/terminal. In theory, we shouldn't need win32 APis, especially if terminals are going through ConPTY but we'll see.

I'd honestly take whatever you need from PDCurses. You could probably use much of what's there to even provide the ncurses shim you've file an issue for.

i think that failure to enter cbreakesque mode is our main blocker now on Windows Terminal, as we hang up after sending queries, but progress if the user hits enter on the keyboard.

as we hang up after sending queries, but progress if the user hits enter on the keyboard.

You should be able to simulate pressing that enter key. Typically simulating user actions are for tests but if that's what's needed until another method can be found, it's a quick work-around.

alright, we're now advancing forward to creation of the initial plane, which breaks because we don't have good geometry on windows yet

the scroll PoC now starts in a WIndows Terrminal when run from a directory containing all necessary DLLs

closing this, and we'll pursue remaining windows issues in their own bugs
