This is a Neovim extension that is supposed to offer two things:
- a framework for highlighting "heat".
- some useful builtins
A simple builtin is highlighting timestamps by recency.
This is very useful for git-blame views, and the plugin also automatically colors vim-fugitive blame (ft=fugitiveblame) buffers.
However, its more general than that: say, something that you're working with maps (at least in your mental model) to "heat"; some of these values are "hotter" (more significant), others are "colder" (less so). Then, as long as you can find and label these values, you can use the plugin to color them nicely. 🙂
