Clangd Research Artifacts (CS323 Report)

This repository contains the modified source code and experimental scripts for the course report:
"Language Server Protocols: Surveying How Compiler Frontends Enable Intelligent Features".

The modifications were made based on the LLVM Project (approx. version 12-15). These instrumentations allow us to trace the internal lifecycle of LSP requests.

📂 Repository Structure

• src/clangd/: Contains the modified C++ source files from llvm-project/clang-tools-extra/clangd/.
  • Selection.cpp: Instrumented to dump the SelectionTree structure (Case Study 1).
  • XRefs.cpp: Instrumented to trace the locateSymbolAt and resolution layer (Case Study 1).
  • ClangdLSPServer.cpp: Instrumented to capture LSP layer requests (Case Study 1).
  • FuzzyMatch.cpp: Instrumented to print scoring details for code completion (Case Study 2).
  • Preamble.cpp: Instrumented to log preamble build triggers (Case Study 3).
• tests/: Contains the C++ test cases used to trigger the logs.

🚀 How to Use

1. Replace the corresponding files in a standard llvm-project source tree with the files in src/clangd/.
2. Recompile clangd using make clangd.
3. Run clangd with your editor or via command line to see the >>> [Experiment] logs.
