Treesitter from Scratch — Syntax Highlighting, Text Objects & Code Folding | Episode 8

Add Treesitter to your Neovim config for AST-powered syntax highlighting, smart text objects, and code folding! In Episode 8, we install nvim-treesitter with 7 language parsers, create text object keymaps for functions/classes/parameters, and set up incremental selection and fold commands. Every keystroke is shown on screen with 3-second pauses so you can follow along at your own pace. What You'll Learn: - nvim-treesitter: AST-powered syntax highlighting and indentation - build = ":TSUpdate": compiles parsers on install and update - ensure_installed: parsers for lua, python, kotlin, tsx, javascript, html, css - highlight = { enable = true }: replaces regex with AST awareness - indent = { enable = true }: treesitter calculates correct indentation - incremental_selection: Enter expands by AST node, Backspace shrinks - :InspectTree: view the full AST for any file - nvim-treesitter-textobjects: select, move, and swap code by structure - af/if: around/inner function, ac/ic: class, aa/ia: parameter - ]m/[m: jump to next/previous function start - foldmethod = "expr" with treesitter foldexpr: fold by syntax - zM/zR: close/open all folds, zc/zo/za: close/open/toggle Timestamps: 0:00 - Introduction 0:15 - What You'll Learn (Preview) 0:45 - Treesitter Setup (Plugin Spec + Highlighting Demo) 4:04 - Text Objects (Select, Move, Swap) 8:27 - Selection & Folding (Incremental Selection + Fold Commands) 11:34 - Recap: 5 Key Takeaways This is Episode 8 of the Neovim Tutorial Series.
