# git-watch: A streaming perspective of git changes and commits.

# Monitors the current repository for:
|
|
# - New commits (displays 'git show')
|

# - Working directory & index changes (displays 'git diff HEAD' and untracked files)

|

# Prefers 'watchexec' for responsiveness but falls back to a loop.
