🦑 Hyjinx 🔬

Functions and macros for modern living in the Hy REPL.

Compatible with Hy ≥ 1.2.0 · Python ≥ 3.13

Hyjinx is a utility library for Hy. When a module stabilises, it gets spun out into its own package (e.g. beautifhy).

CLI

$ hyjinx where hyjinx.macros.defmethod
/path/to/hyjinx/macros.hy:94

$ hyjinx where json.dumps --json
{"line": 184, "module": "json", "file": "...", "language": "python", "extension": "py"}

$ hyjinx dir hyjinx.result
hyjinx/result.hy  [14 definitions]

$ hyjinx dir hyjinx.lib --kind defn --no-params

$ hyjinx source hyjinx.api.format-surface --no-highlight
(defn format-surface [defs * [show-params True] [show-line False]]
  ...)

$ hyjinx doc hyjinx.api.api-surface
Return a list of definition dicts for a source file.
Each dict has keys: kind, name, params, line.
No imports are performed — purely static analysis.

The dir command uses static analysis — it parses source files without importing them, so it never triggers side effects (DB connections, GPU init, etc.).

Install

pip install hyjinx

Optional dependencies:

pip install hyjinx[zmq]   # ecdsa, pyzmq, zstandard, msgpack
pip install hyjinx[llm]   # openai, anthropic
pip install hyjinx[dev]   # pytest + all optional dependencies

For offline Hy/Hyrule/Toolz documentation:

hy -m hyjinx.docs

For in-terminal sixel rendering of LaTeX in LLM replies, install pdflatex, dvipng, and img2sixel, and use a sixel-capable terminal.

Hylights

• defmethod — polymorphic type dispatch via multimethod
• Result type — ok/err with result->, let-result, match-result, try-result
• defstruct — frozen dict-like records
• Static API inspection — api-surface parses Hy/Python source without importing
• Hy-aware inspect — getsource, getsourcefile that handle macros and multimethods
• LLM integration — discuss code with ChatGPT, Claude, or local models
• ZMQ lazy pirate — reliable RPC client/server with automatic retries
