## What it is
A format runner plugin for Neovim written in Lua that executes external formatters asynchronously on buffers. It provides opt-in default formatter configurations per filetype, conditional formatting, and before/after hooks.

## Use cases
- format code on save in neovim
- run stylua or prettier from neovim
- remove trailing whitespace across filetypes
- set up per-filetype formatter configurations
- asynchronous code formatting in neovim
- conditionally skip formatting for certain files

## When to choose
- you use Neovim and want a Lua-native, configurable formatting runner
- you need fine-grained control over which formatters run per filetype
- you want asynchronous formatting with buffer locking to avoid race conditions

## When to avoid
- you use plain Vim rather than Neovim
- you prefer an all-in-one LSP-based formatting setup with no external plugin
- you need an IDE with built-in formatting

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