smartfolds.nvim — Day 1: Parsing Folds and First Steps into Treesitter

Today marks Day 1 of building my new Neovim plugin: smartfolds.nvim!

After feeling stuck for a while doing the same kinds of projects, I promised myself I would step outside my comfort zone. This project is my attempt at that: trying new things, exploring new tools, and maybe (hopefully!) finding that spark again.

And wow, today was super exciting. 🚀

What I worked on today

The goal was simple (in theory):

"Get a rough version of fold parsing working."

In Neovim, folds usually just collapse code into a block and show a line filled with dots (······), which isn't super helpful when you're scrolling fast.

I want smartfolds.nvim to actually understand the code inside a fold and display something smart — like the function name and signature — instead of just the first random line.

Today, I managed to parse the folded text using Treesitter, and extract the function signature if a folded area contains a function!

Things I learned today

• vim.v
  I discovered that vim.v is a special table that holds Vim's predefined variables, like vim.v.foldstart and vim.v.foldend.
  Super handy for working with folds!

• Treesitter Basics
  This was my very first time playing with Treesitter.
  I learned how to parse the syntax tree for the current buffer, iterate over nodes, and find things like function declarations.
  It's still a bit magical to me, but I’m starting to get the hang of it.

Here’s what it looks like so far

The fold text now shows a little function signature instead of boring dots.
It's a small thing, but it already feels so much more powerful.

Final thoughts

Honestly, today felt amazing.

It’s a small first step, but it reminded me why trying new things is so important.
I have no idea if smartfolds.nvim will ever be "popular" or even "good," but I already feel proud that I started.

This is me getting unstuck, one fold at a time. (pun intended 😂)

Stay tuned for Day 2! 🚀
