Parse Pine Script™. Run it. Deploy it. Own the AST.
ANTLR4 grammar, ASDL tree, and multi-run AST cache — every token inspectable.
Bar loop with incremental TA, unused-derived skip, and strategy events — Python, Workers, or isolate.
Warm Numba path and mode=auto — disk IR cache, prewarm, sub-ms reruns when hot.
Strategy events, alerts export, and L2 webhooks — desk, Pro API, and edge.
Usage — section loads with JavaScript. Open docs
Surfaces — section loads with JavaScript. Open docs
Four entry points, one stack. Pick the surface that matches the job — desk, API, edge, or editor.
pip install "hoox-pyne" — import package is pynescript. Parse, lint, evaluate, and round-trip Pine Script™-compatible scripts with high fidelity on your machine — see the status matrix for live coverage.
$pip install "hoox-pyne"Open CLI →POST scripts and OHLCV to a stable evaluate contract — mode, alerts, libraries, optional webhook_url. Same payload shape on desk, worker, or custom host.
$curl -X POST $HOST/run …API surface →Deploy pyne-worker for edge POST /run. Import PyneTS (@hoox-sh/pynets) for in-process TypeScript evaluate. Optional pyne-agent-worker writes scripts from chat.
$npx wrangler deployWorkers →Install the LSP and the PYNE VS Code extension. Autocomplete 940+ builtins, diagnostics, hover docs, outline — VS Code, Neovim, Zed, Emacs. Opens .pyne and .pine.
$pip install "hoox-pyne[lsp]"LSP setup →Strategies should not die with a tab. Evaluate at the edge or on a server you control — with alerts out via webhooks.
Multi-year bars on data you store — not a 20k ceiling tied to a subscription. Series caps and incremental TA keep long series practical.
ANTLR4, ASDL, public builtins. If you cannot inspect the runtime, you cannot trust the fill.
The desk surface. Parse, lint, format, run, optimize, and catalog builtins without opening a browser. PyPI ships as hoox-pyne 0.6.4; preferred CLIs are pyne / pyne-lsp (pynescript* aliases remain).
