React - Functional error boundaries

Thanks to React hooks you have now happily turned all your classes into functional components.

Wait, all your components? Not quite. There is one thing that can still only be implemented using classes: Error boundaries.

There is just no functional equivalent for componentDidCatch and deriveStateFromError yet.

How to have some fun using the terminal.

	set ruler " Show the line and column numbers of the cursor.
	set formatoptions+=o " Continue comment marker in new lines.
	set textwidth=0 " Hard-wrap long lines as you type them.
	set modeline " Enable modeline.
	set esckeys " Cursor keys in insert mode.
	set linespace=0 " Set line-spacing to minimum.
	set nojoinspaces " Prevents inserting two spaces after punctuation on a join (J)
	" More natural splits
	set splitbelow " Horizontal split below current.

	# Download this script as "git-recentco" (no extension), chmod it to be executable and put it in your
	# path somewhere (e.g. /usr/bin). You can then use it via `git recentco` from inside any git repo.

	# Example:
	#

	# put this in your .bash_profile
	if [ $ITERM_SESSION_ID ]; then
	export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
	fi

	# Piece-by-Piece Explanation:
	# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
	# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
	# the $PROMPT_COMMAND environment variable is executed every time a command is run
