python-lsp

A thin, dependency-free Python client that owns the LSP lifecycle against pyright-langserver --stdio and exposes high-value semantic queries.

Why, over tree-sitter / ripgrep: tree-sitter gives a CST — structural queries, call-site enumeration by name. It cannot do name resolution, type inference, or cross-file binding. ripgrep matches text, so it false-positives on shadowed / same-named symbols. pyright resolves bindings. This client is that semantic overlay.

Setup (self-installing)

The client bootstraps pyright on first use. Run the bootstrap explicitly, or let LSPClient do it via ensure_pyright():
