lei interactive TUIs (ncurses/vim/emacs)

[Eric Wong <e@80x24.org>]

I hardly have any experience in this area; but automatic
end-to-end tests for ncurses and other TUI stuff seems
like a huge pain...

I've also noticed vim has scripting abilities (like Emacs?) and
notmuch bundles a vim extension we can take inspiration from.
Perhaps we could bundle vim and Emacs extensions for lei, too...

While I use vim[1], I've always kept my vim decoupled from Perl
(or Lua, Python, Ruby, TCL, etc) and rather tie stuff together
with pipes.  IOW, I'm happy my editor can run arbitrary shell
commands; but don't want stuff linked into my editor (since more
code is usually more fragile).

So, any thoughts on this matter?

Anybody willing to maintain an lei TUI for emacs?
I might give a vim TUI a shot...

But writing and testing a FUSE FS is much more natural...


[1] My choice to use vi/vim is merely because it's the most
    widely-installed editor on random systems I ssh into.
    It also mostly works the same after a few decades w/o
    needing UI changes; same goes for Perl.
