I tried Ghostty earlier in the week, but couldn’t get it set up to look the same as iterm2 (the colours are off and text looks different somehow with the same typeface at the same size). Which is just cosmetic but makes it feel wrong viscerally.
Somehow this is the first time I see anyone else bring this up, but the fonts are absolutely displayed with wrong kerning on my mac, for my font (at 12pt) I was able to make it look the same as iTerm2 with adjust-cell-{width,height} both set to -5%.
I had an issue where Ghostty failed to render the text "th", so I think Ghostty just generally has a lot of font issues. Gave up trying to use it within minutes.
It seems that I had iTerm2 configured to display bold text as bright text (instead of bold). And I use bold, coloured text in my prompt, so that threw me.
I configured
bold-is-bright = true
and suddenly everything looks fine. I'll see how I get on with it.
I noticed the colors looked off when I was trying out Ghostty as well. Adding this line to my config fixed it after restarting the app: `window-colorspace = display-p3`
Ghostty supports iTerm themes, so you should be able to transfer your preferred look-and-feel directly. I just picked one I liked, so I'm not familiar with the process, but it can be done.
It looks like the process is more manual than I thought, sorry. There's something which imports themes from the iTerm2 color schemes website weekly, but from what I can find that isn't a feature which ships with Ghostty itself.
Here's the relevant docs page, which I hope explains why I mistakenly thought that transferring a theme directly from iTerm to Ghostty was possible. You could upload your theme to the website they're being sourced from, and wait a week. But that's clearly not the same thing.
I’ll give it another go at the weekend.
