Italics in Tmux using Kitty's terminfoEvan Travers
I'm presently using Kitty as my terminal emulator.
I had been using iTerm2 for years, and it is an excellent emulator. After trying Alacritty1, I settled on Kitty. Kitty was fast, cross-platform, and simple to configure. I use tmux as my multiplexer, so having a very bare-bones terminal that is easy to configure makes lots of sense to me. I haven't looked back.2
Kitty has another advantage that I discovered only very recently. I recently switched my font to Jetbrains Mono on a lark, and started to look and see what would be required in order to get italics and underlines to work properly in my terminal. To get tmux to play nice with italics, you have to specify a terminfo file that also supports it, and most people were rolling their own custom one.
It turns out that kitty supplies a custom terminfo
that supports all the features I could ever want, so all I have to do is tell
tmux to use
xterm-kitty3, and I'm done! It was a lot easier than
making a shell script that copies my standard terminfo, patches it with italic
support, and installs it using tic.
I've tested it only a little bit, but this appears to work in other terminals
as well. You could just
brew cask install kitty, and continue to use it in
Terminal.app or iTerm2.
If you don't like messing with things, it's probably the best choice. As it was, I wanted to look around at the other options… especially with an eye to speed, and I wanted a simple textfile configuration option rather than the messy plist format that iTerm stores its data in. ↩
I still miss one iTerm feature: I haven't found a suitable replacement for iTerm2's mark system. It's wonderful.
