callix

Polyglot code analysis in Rust. Parses Python, TypeScript, Go, Rust, PHP, C, C++ and YAML into a shared graph IR — with the type checkers linked in, so there are no language servers to install.

Documentation · Repository · Issues

Repository → Language Adapter → Graph (IR) → your code

Nodes and directed relations, typed and deterministic: functions, classes, modules, the calls between them, and the HTTP or gRPC boundaries where one service meets another.

Why

Code analysis usually asks you to assemble it — install a language server, put it on PATH, wire up the transport, keep the versions in step. callix links the analysis engines into the module instead:

Language	Symbol resolution	Extra setup
Python	ty, linked as a library	none
TypeScript	typescript-go, linked as a Go c-archive	none
Go	`go/packages` + `go/types`, same c-archive	a Go toolchain
Rust	`rust-analyzer scip` index, decoded natively	`rust-analyzer` and Cargo
PHP	a symbol table built from the sources	none
C / C++	a symbol table over the parsed sources	none
YAML	none — it declares no symbols	none

Python and TypeScript need nothing beyond the wheel — the checkers and their standard-library stubs are inside it. Go and Rust use the toolchain the project already has, because a standard library shipped as sources cannot be frozen into a wheel. PHP and the C family have no checker worth linking and no widely installed indexer worth shelling out to — every precise C/C++ option requires a compile_commands.json, which almost no repository ships — so callix builds a symbol table from the sources and reports degraded, honest about being a symbol table and not a type checker.

Installation

pip install callix

Python ≥ 3.10. Wheels for Linux glibc and musl (x86_64, aarch64) and macOS (arm64, x86_64); Windows is not supported.

The published release is 0.1.0 — four adapters (Python, TypeScript, Go, Rust) and Python ≥ 3.13. PHP, C, C++ and YAML are on main and unreleased; build from source to use them.

Usage

from callix import NodeKind, PythonAdapter

graph = PythonAdapter().analyze("path/to/project")

print(len(graph.nodes), len(graph.relations))
for node in graph.nodes_by_kind(NodeKind.FUNCTION):
    print(node.qualified_name, graph.callers(node.id))

graph.to_json(indent=2)          # serialization
old.diff(new)                    # structural diff

The same call works for every other language — TypeScriptAdapter, GoAdapter, RustAdapter, PhpAdapter, CAdapter, CppAdapter, YamlAdapter — and each discovers its own project roots, so a monorepo works without configuration.

Symbol resolution is on by default. resolve=False gives a structural graph; graph.metadata["resolver_status"] always says how complete the result is.

A Python server declaring @app.get("/users/{id}") and a TypeScript client calling fetch("/users/1") produce the same boundary node, so merging their graphs links the two services. See Cross-language analysis.

Versioning

Semver covers the graph contract — the node and relation kinds, the two id formulas, 1-based spans, node ordering, the serialization format — and the Python API as generated into the committed .pyi. It does not cover what the resolvers answer: the Python one is a pinned 0.0.x release of ty, the Rust one is whatever rust-analyzer the machine has. A patch release may change which CALLS edges appear. What is watched instead is the aggregate share of resolved queries, recorded per project in the baselines.
