Let me know if you want upgrades.

Note: This project made with AI. It does work. Use with caution. I quickly build this project (in 1 hour) just for using ZED with Blazor-Razor pages. It lacks structure, coding standarts, and every other professional aspect. Just an AI slop

A Tree-sitter grammar for ASP.NET Razor Pages (.razor, .cshtml).

This grammar provides robust parsing for the Razor syntax, including:

• Directives (@page, @inject, @code, etc.)
• Control structures (@if, @foreach, @switch, etc.)
• Explicit and implicit C# expressions (@(...), @someVar)
• HTML integration with attributes
• C# code block injection

• Accurate Parsing: Handles mixed C# and HTML content typical in Razor files.
• Syntax Highlighting: Includes queries for syntax highlighting.
• Injection Support: seamless C# injection inside @code blocks and control structures.
• Zed Editor Support: Ready-to-use integration for the Zed editor.

• Node.js (v18+)
• C Compiler (MSVC on Windows, GCC/Clang on Linux/macOS)
• Tree-sitter CLI (npm install -g tree-sitter-cli)

1. Clone the repository:

   git clone https://github.com/yourusername/tree-sitter-razor.git
   cd tree-sitter-razor

2. Install dependencies:

   npm install

3. Build the grammar:

   npm run build
   # or
   tree-sitter generate

Run the corpus tests to verify the grammar:

# Standard test run
tree-sitter test

# Windows specific helper (sets up VS environment)
.\run_test.bat

To parse a specific file and see the syntax tree:

tree-sitter parse test/counter.razor

This repository includes a local extension setup for Zed.

1. Navigate to the zed-razor directory.
2. Ensure you have a compiled WASM grammar:

   tree-sitter build --wasm
   copy tree-sitter-razor.wasm zed-razor\grammars\razor.wasm

3. Open Zed and install the extension as a "Dev Extension" pointing to the zed-razor folder.
