Adding dot-repeat to your Neovim plugin

In Neovim, the . character repeats "the most recent action"; however, this is not always respected by plugin actions. Here we will explore how to build dot-repeat support directly into your plugin, bypassing the requirement of dependencies like repeat.vim.

The Basics

When some buffer-modifying action is performed, Neovim implicitly remembers the operator (e.g. d), motion (e.g. iw), and some other miscellaneous information. When the dot-repeat command is called, Neovim repeats that operator-motion combination. For example, if we type ci"text<Esc>, then we replace the inner contents of some double quotes with text, i.e. "hello world" → "text". Dot-repeating from here will do the same, i.e. "more samples" → "text".

Think twice before abandoning X11. Wayland breaks everything!

Wayland breaks everything! It is binary incompatible, provides no clear transition path with 1:1 replacements for everything in X11, and is even philosophically incompatible with X11. Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.
