My vim/nvim secret sauce

Here is an overview of some of the core customizations I have built for my own vim/nvim setup over the years. Sometimes I try to explain and share to friends and people online, but it's very difficult to summarize what they are, so I am collecting an overview and code snippets of the current state of my tweaks at the time of writing, here. You can find my full and up to date vim config at my dotfiles repo

Along the way whenever I describe workflows in vim I will highlight the count of keystrokes. In a sort of pragmatic vim golf fashion many of my tweaks are made with an eye toward reducing the number of keystrokes required to achieve a given common task.

Enhanced dot: A search and repeat synergy

This gist is written to address challenges related to copying data out of buffers that you may encounter when using tools in the terminal, in particular in dealing with modern versions of tmux and vim. Care is taken to use these tools with their configuration that is provided out of the box.

Couple of notes:

All of this applies across Linux and macOS.
Note that the "copied to clipboard" notification you will see in demos below is being generated by the Clipboard Indicator GNOME extension tool. It is useful to demonstrate as it happens when content is successfully preserved into our system clipboard. It also offers very useful clipboard history management, although many other apps can be used for the same purpose. For example, on macOS, I prefer to use the clipboard manager that is built into BetterTouchTool.

Let us proceed!

Outside tmux (plain terminal)

Click+drag to select content. Your terminal emulator will either implicitly g

	if ! git diff --quiet HEAD --; then

	echo "Please commit or stash your changes before running git-undo." >&2
	exit 1
	fi

	# lf Previewer Script with Caching for Performance
	#
	# Design Goals:
	# 1. Fast Scrolling: Avoid re-running expensive generation (like bat) on every scroll.
	# 2. Caching: Generate full preview content once per file version, store it.
	# 3. Cache Invalidation: Use file modification time (mtime) in cache keys to automatically
	# handle file changes.
	# 4. Large File Handling: For text-based files, only process the head and tail lines for faster generation.
	# 5. File Type Handling: Support various types (text, json, binary, compressed).
