STCursorword

A concise, precise, and high-performance cursor word highlighting plugin for Neovim, implemented in Lua.

Reasons for creating this plugin

🎉 There are many plugins that do this, but none of them support disabling for certain filetypes. So, If I accidentally open a binary file such as .png file it gives me an error

🛠️ Other plugins always reset highlighting when the cursor moves, whereas this plugin does not. It only resets the highlighting when the cursor moves to a new word.

For example, if the cursor is on the character h in the word hello, and you move the cursor to e, other plugins will remove the highlighting from the word hello and then highlight it again, even though the cursor is still on that word. Consequently, when you move to the o, it will undergo highlighting five times.

🍕 Easily to disable and enable when needed.

🚀 And a subjective reason is that I used to use the nvim-cursorline plugin before, but I don't use the cursorline feature. Another plugins i found that nvim-cursorword, it works quite similar to this plugin, but its setup method is not like the plugins I usually use. So this is the reason for this plugin.
