formatter.nvim

Formatter.nvim is a Neovim plugin that runs external code formatters on your files. It provides a flexible and asynchronous way to format code across many languages, helping developers maintain consistent code style without leaving the editor.

Key Features

• Asynchronous Execution — Runs formatters in the background without blocking the editor.
• Buffer Locking — Prevents modifications during formatting with lock commands.
• Opt-in Default Configurations — Includes pre-built formatter setups for common filetypes that you can choose to use.
• Conditional Formatting — Allows formatter configurations to include logic for when to run.
• Before/After Hooks — Execute custom code before and after formatting via autocommands.
• Filetype-specific Setup — Configure different formatters per filetype with ordered execution.

Philosophy

Formatter.nvim believes in providing a robust, non-blocking formatting experience while giving users full control over their configurations, avoiding assumptions about preferred tools.
