## Description

sourcekit-lsp is a language server protocol implementation and IDE code intelligence backend. It functions as a Swift language server and source code indexer, providing semantic analysis, autocomplete, and navigation features to compatible text editors.

The project integrates directly with the Swift toolchain and SourceKit framework to deliver precise type information. It also leverages Clang-integrated parsing to provide semantic analysis for C-family languages, enabling cross-language navigation across project files.

The server manages source code indexing and symbol lookups while using a file-watching event loop to handle incremental updates. It communicates via a standardized JSON-RPC protocol to provide consistent editor support across different host applications.
