Create a brick tui

Brick is a terminal ui: https://hackage.haskell.org/package/brick

It shouldn't be hard. The main view would be equivalent to ghcup list and allow easier interaction per item.

@jtdaugherty wdyt?

Awesome idea! Then again, I have a certain bias on this question.

Yes, I think this is 100% feasible and would make a nice alternative to the current interface (although keeping the current interface makes ghcup easier to use in a scripting context, which I would think is important).

I am happy to be available for support via tickets and email if you tackle this. There is extensive documentation in the Brick library (not just Haddock; see the User Guide) as well as a large collection of demo programs.

Something you might want to consider: brick (via vty) is not compatible with (or supported on) Windows.

(That could just mean you conditionally compile that out on Windows; another reason to keep the non-TUI implementation.)

ghcup currently has zero windows support. It heavily relies on unix. Windows is just too much of a different platform, imo. There's also discussion at ghc/ghc#18104
