Ghostty Configuration

I got recently annoyed with iTerm2 encountering random lag and using infinite CPU slowing everything down. It happened at a moment of personal exasperation so I decided to try out Ghostty since I've tried alacritty before and it was too minimal for me. I know some people prefer managing their panes in tmux but I prefer having my terminal emulator provide windowing features. So the minimal amount of things I needed were:

• Window Splits
• Tabs
• Keyboard control on MacOS to move between those

After I actually used Ghostty, I realized I also wanted:

• A block cursor, that in neovim follows the insert-mode-bar, normal-mode-block convention
• Support for Shift-Enter in Claude Code

Ghostty fortunately supports both of these, though it has its MacOS configuration file in a very MacOS location and I would have preferred that it live in ~/.config. It claims to support that path but doesn't actually seem to, so I just decided to use the weird "Application Support" path. In any case, here are the requisite configuration options

# Cursor configuration
# https://github.com/ghostty-org/ghostty/discussions/3836
cursor-style = block
cursor-style-blink = false
# no-cursor removes the default blinking bar
# ssh-terminfo,ssh-env,sudo transmit the terminfo so CLIs know how to handle paging / colors
shell-integration-features = no-cursor,ssh-terminfo,ssh-env,sudo

# Claude Code Shift-Enter
# https://github.com/anthropics/claude-code/issues/1282
keybind = shift+enter=text:\x1b\r
