A basic overview of how to manage dot-repeating in your Neovim plugin, as well as manipulate it to "force" what action is repeated.

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".

How to make a game loop for your idle game

How do I make a game loop for my Idle Game?

Interval-Based Resource Generators

So, you want to build an idle/incremental game in JavaScript and you’ve read on the internet that setInterval is the way to go when it comes to handling resources that automatically generate over time.

You get started, you write down your setInterval function, you set it to trigger once every 1000 milliseconds, and every time it triggers, you add 1 to the player’s total resource count. Perfect. It works.

Uh-oh.
