diffs.nvim

Syntax highlighting for diffs in Neovim

Enhance vim-fugitive and Neovim's built-in diff mode with language-aware syntax highlighting.

Features

• Treesitter syntax highlighting in :Git diffs and commit views
• :Gdiffsplit / :Gvdiffsplit syntax through diff backgrounds
• Background-only diff colors for any &diff buffer (:diffthis, vimdiff)
• Vim syntax fallback for languages without a treesitter parser
• Hunk header context highlighting (@@ ... @@ function foo())
• Configurable debouncing, max lines, and diff prefix concealment

Requirements

• Neovim 0.9.0+
• vim-fugitive (optional, for unified diff syntax highlighting)

Installation

Using lazy.nvim:

{
  'barrettruth/diffs.nvim',
  dependencies = { 'tpope/vim-fugitive' },
  opts = {},
}

Or via luarocks:

luarocks install diffs.nvim

Documentation

:help diffs.nvim

Known Limitations

• Syntax "flashing": diffs.nvim hooks into the FileType fugitive event triggered by vim-fugitive, at which point the buffer is preliminarily painted. The buffer is then re-painted after debounce_ms milliseconds, causing an unavoidable visual "flash" even when debounce_ms = 0.
