## What it is
conform.nvim is a lightweight yet powerful code formatter plugin for Neovim. It wraps external formatter binaries and LSP formatting into a simple API while preserving extmarks, folds, and cursor position via minimal diff application.

## Use cases
- format code on save in neovim
- run prettier or black from neovim
- format only a selected range in a buffer
- format code blocks inside markdown files
- fix LSP servers that replace the whole buffer when formatting
- replace null-ls formatting in my neovim setup

## When to choose
- you use Neovim 0.10+ and want fast, configurable code formatting
- you need minimal-diff formatting that preserves folds, extmarks, and cursor position
- you want range formatting even for formatters that don't natively support it

## When to avoid
- you don't use Neovim (e.g. you use VS Code or vanilla Vim)
- you need an all-in-one linting/Diagnostics/hover solution rather than just formatting

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