Slangd - SystemVerilog Language Server

Slangd is a SystemVerilog language server implementing the Language Server Protocol. Built on the Slang compiler frontend, it provides accurate language intelligence for SystemVerilog projects.

Features

• Diagnostics - Real-time syntax and semantic error detection
• Go-to-definition - Navigate to symbol definitions across files
• Document symbols - Outline view for modules, classes, packages, and more
• Workspace indexing - Fast cross-file navigation and symbol resolution
• Flexible configuration - Auto-discovery with directory skipping, explicit file lists, path filtering, and more

Development

Project Goals

• Build a SystemVerilog Language Server (slangd) using Slang and C++23
• Provide a reusable, language-agnostic LSP core library (lsp)
• Implement clean asynchronous LSP communication using jsonrpc and asio
• Follow modern C++ design practices for robustness and maintainability

Requirements

• Bazel 7.0+ for bzlmod support
• Clang 20+ for C++23 support

Building and Testing

Build the project:

bazel build //...

Run tests:

bazel test //...

Generate compile_commands.json for IDE integration (optional):

bazel run @hedron_compile_commands//:refresh_all
