**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`](https://github.com/tpope/vim-fugitive) (optional, for unified
|
|
diff syntax highlighting)
|
|
|
|
## Installation
|
|
|
|
Install with your package manager of choice or via
|
|
[luarocks](https://luarocks.org/modules/barrettruth/diffs.nvim):
|
|
|
|
```
|
|
luarocks install diffs.nvim
|
|
```
|
|
|
|
## Documentation
|
|
|
|
```vim
|
|
: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`.
|
|
|
|
- **Conflicting diff plugins**: `diffs.nvim` may not interact well with other
|
|
plugins that modify diff highlighting. Known plugins that may conflict:
|
|
- [`diffview.nvim`](https://github.com/sindrets/diffview.nvim) - provides its
|
|
own diff highlighting and conflict resolution UI
|
|
- [`mini.diff`](https://github.com/echasnovski/mini.diff) - visualizes buffer
|
|
differences with its own highlighting system
|
|
- [`gitsigns.nvim`](https://github.com/lewis6991/gitsigns.nvim) - generally
|
|
compatible, but both plugins modifying line highlights may produce
|
|
unexpected results
|
|
- [`git-conflict.nvim`](https://github.com/akinsho/git-conflict.nvim) -
|
|
conflict marker highlighting may overlap with `diffs.nvim`
