Not loading/parsing unknown terminfo files

[mitchellh]

Describe the bug Hi! 👋 I'm working on a new terminal emulator. It is very full featured and has dozens of full time testers. One recently reported lazygit doesn't work in it, and I realized that doing TERM=xterm-256color lazygit fixes everything.

Ghostty sets TERM to xterm-ghostty but also sets TERMINFO to a valid terminfo database path. (See https://man7.org/linux/man-pages/man5/terminfo.5.html) See below:

To Reproduce I can get you access to the terminal, but running lazygit with a TERM thats unknown and a TERMINFO set to a path that defines $TERM will work just as well.

Expected behavior lazygit should dynamically parse terminfo to accept terminals it doesn't know about.

Screenshots The below happens instead, but it renders and functions perfectly if I set TERM=xterm-256color.

Version info:

commit=, build date=, build source=homebrew, version=0.40.2, os=darwin, arch=arm64, git version=2.36.0

Additional context I dug into it a bit and it looks like your dependency tcell supports dynamically parsing terminfo/termcap files. Please let me know if I'm doing anything wrong here.

Similar issue here. I use iterm2. I have compiled and installed the iterm2's terminfo file to ~/.terminfo. Other command line utilities (like macOS builtin ls) are confirmed to respect the installed terminfo file.
