# Terminal Type Configuration (for Tmux compatibility)
[env]
# Explicitly set the terminal emulation type for optimal compatibility
# Alacritty identifies itself by default, but this ensures correct behavior inside tmux
TERM = "xterm-256color"
# When inside tmux, it usually wants screen or tmux-256color for optimal performance
# For most use cases, Alacritty's default configuration will handle this handshake
# internally, but you can explicitly set it here if necessary:
# TERM = "screen-256color"
