<!-- openclaw-plugin-reference:manual-start -->

## Added languages

The base `diffs` plugin already highlights the common languages documented in [Diffs](/tools/diffs). Install this language pack when you want syntax highlighting for a broader set of Shiki-supported languages. If the pack is not installed, those files still render as readable plain text.

Examples include:

- Astro
- Vue
- Svelte
- MDX
- GraphQL
- Terraform/HCL
- Nix
- Clojure
- Elixir
- Haskell
- OCaml
- Scala
- Zig
- Solidity
- Verilog/VHDL
- Fortran
- MATLAB
- LaTeX
- Mermaid
- Sass/Less/SCSS
- Nginx
- Apache
- CSV
- dotenv
- INI
- diff files

See [Shiki languages](https://shiki.style/languages) for Shiki's upstream language and alias catalog.
