Parse Pine Script™. Run it. Deploy it. Own the AST.
ANTLR4 grammar, slotted ASDL tree, and a multi-run AST cache — every token inspectable.
Bar loop with incremental TA and a persistent InterpretSession — O(1) forming-bar ticks, O(delta) appends.
Warm Numba path and mode=auto — disk IR cache, prewarm, sub-ms reruns, object-mode residual recovery.
Strategy events, alerts export, and L2 webhooks — plus a live /ws/live plane with delta envelopes.

hoox-pyne 0.6.32 fixes outline symbols on generic types and re-packs VS Code 0.5.6. 0.6.31 ships dedicated compose datafeed and MCP daemons, publishes ghcr.io/hoox-sh/pyne/mcp, and matches AXIS hover/suggest chrome in the editor. 0.6.30 listed hoox-sh.pyne on the Visual Studio Marketplace with a scope-aware LSP semantic layer. This plate is the recent surface — not the full changelog.
hoox-pyne 0.6.34 · 2026-11-02
Full changelogTyped locals such as array<float> and map<string, float> no longer crash textDocument/documentSymbol — Specialize.args is an expression, not a list. The outline still returns any symbols already collected if a later visitor step fails. VS Code extension 0.5.6 re-packs the fix; the language server still comes from hoox-pyne.
Still openStill open: known TradingView® platform divergences and optional set0x community-corpus plot parity. Official TradingView® builtins are 0 MISMATCH vs compile (0.6.2). See the known-divergences note. The corpus figure is interpret coverage, separate from hosted-platform parity.
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.

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.
Desk CLI, HTTP API, and Cloudflare® Workers — one Pine Script™ grammar, five surfaces.
CLI · DESK SURFACE
The desk surface. Parse, lint, format, run, optimize, and catalog builtins without opening a browser. PyPI ships as hoox-pyne 0.6.34; preferred CLIs are pyne / pyne-lsp (pynescript* aliases remain).

Software freedom means the evaluator survives any single company. The code stays open; operators choose the best runtime of the code.
