history

Project history and usage

pylyzer is a fast Python type checker and language server written in Rust.

Project history

pylyzer was developed as a Rust-written Python static analyzer and language server built on the Erg type checker. Upstream now describes it as being in maintenance mode and points users toward Astral's ty for future feature development.

Adoption history

The supplied package facts record Homebrew and Nix packaging. Upstream also documents installation through pip, Cargo, GitHub releases, and a VS Code extension.

How it is used

Run `pylyzer file.py` to analyze files, invoke it without a path to search for a package entry point, or use `pylyzer --server` with an LSP-aware editor. Project options can be declared in `pyproject.toml`.

Why package nerds care

pylyzer belongs to the wave of Rust-based Python developer tools that pursued much faster analysis while offering language-server integration. Its use of the Erg type checker makes it an unusual bridge between Python tooling and the Erg language ecosystem.

Timeline

  • Maintenance phase: Upstream limited pylyzer development to bug fixes while its author began cooperating on ty.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.

local files

Configuration and credential file locations

These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval.
