## What it is
TreeSJ is a Neovim plugin written in Lua that splits and joins blocks of code such as arrays, objects, and dictionaries using Tree-Sitter. It works from anywhere in a block, supports recursive and nested-language operations, toggle mode, and dot-repeat.

## Use cases
- split a multi-element array onto separate lines in Neovim
- join an object or dictionary back into a single line
- toggle code block formatting with one keypress
- recursively expand or collapse nested code blocks
- refactor code layout without moving the cursor to specific positions

## When to choose
- you use Neovim 0.9+ with Tree-Sitter and want splitjoin-style refactoring
- you need language-aware splitting/joining across nested languages
- you want toggle, recursive, and dot-repeat support in one plugin

## When to avoid
- you don't use Neovim or prefer editor-agnostic tools
- you need formatting beyond split/join, such as full code style enforcement

## Facets
- artifact type: plugin
- maturity: active
- function: editor, developer-tools
- domain: developer-tools, text-editors
- platform: editor-plugin, cli
