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".

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.

In mongodb it's easy to make at upsert, meaning update-or-insert by calling

db.collection.update({criteria}, {updated fields}, true)

The third parameter means - insert a new document if the document doesn't exist yet. So, for example, the following will insert a new document for the user if there's no document for that user yet, and will update it if it already exists:

 db.users.update({user_id: '1234'}, {user_id: '1234', name: 'Ran'}, true)
