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
