Phase 7: Shell Prompt

Oh-My-Posh: BROKEN on ARM64 Termux

Oh-my-posh crashes on ARM64 Termux with Go runtime panics (writeSegmentsConcurrently race condition). All themes crash, including built-in minimal themes. disable_async = true does not fix it.

Do NOT use oh-my-posh on Termux. Also: pkg install oh-my-posh installs via pkg (ARM64 native), but the underlying Go binary still panics.

Solution: Use Starship

Starship is Rust-based and works reliably on ARM64.

curl -sS https://starship.rs/install.sh | sh -s -- --bin-dir ~/.local/bin

# Remove oh-my-posh if installed
rm -f ~/.local/bin/oh-my-posh
rm -rf ~/.cache/oh-my-posh

Configure Starship in .zshrc

# Comment out oh-my-posh (broken on ARM64)
sed -i '/^if command -v oh-my-posh/,/^fi$/s/^/#/' ~/.zshrc

# Add starship init
echo 'eval "$(starship init zsh)"' >> ~/.zshrc

Apply a Theme

# List available presets
starship preset --list

# Apply tokyo-night (matches workstation theme)
starship preset tokyo-night -o ~/.config/starship.toml

exec zsh
