terminfo support (scrolling broken without TERM=xterm)

[Ericson2314]

I noticed when using Alacritty that scrolling in reflex-ghci didn't work unless I set TERM=xterm. I would guess this means that reflex-vty isn't doing some terminfo black magic.

I presume ghcid works in that setting?

I don't think ghcid supports scrolling.

True.

What's the value of your TERM variable?

https://github.com/alacritty/alacritty/blob/master/extra/alacritty.info something from there (on phone so can't check directly)

[matt@nixos:~/]$ echo $TERM

Can you share your alacritty configuration? In particular the mouse sections.

{"font":{"size":4.5},"scrollback":{"faux_multiplier":-1,"multiplier":-1}}

That's it. Everything else is the default.

This problem has also been reported with urxvt and TERM=rxvt-unicode-256color.

This looks relevant: https://github.com/jtdaugherty/vty/issues/199

I can confirm that running in alacritty with TERM=xterm-256color or setting the Graphics.Vty.Config termName value to xterm-256color makes mouse interaction work.
