[0.9.0] - 2026-02-27 - Box, Table & Polyline Namespaces, Pine Script Compliance & Critical Fixes

Added

• Box Namespace (box.*): Full implementation of the box drawing namespace — box.new(), box.copy(), box.delete(), and all setter/getter methods (set_left, set_right, set_top, set_bottom, set_bgcolor, set_border_color, set_border_width, set_border_style, set_text, set_text_color, set_text_size, set_extend, etc.).
• Table Namespace (table.*): Full implementation of the table drawing namespace — table.new(), table.cell(), table.delete(), and cell/table setter methods. Tables are positioned at fixed screen locations (position.top_left, position.bottom_center, etc.) and rendered as DOM overlays in QFChart.
• Polyline Namespace (polyline.*): Implementation of polyline.new() for rendering multi-point connected paths from arrays of chart.point objects, with support for curved lines, closed shapes, and fill color.
• Primitive Type Declarations: Added support for int(), float(), and string() cast/conversion expressions in Pine Script syntax (e.g., x = int(someValue)).
• enum Keyword Support: Added enum keyword handling in the transpiler for Pine Script v6 enum declarations.
• Test Coverage: Comprehensive new test suites — box.test.ts, table.test.ts, polyline.test.ts, linefill.test.ts, fill.test.ts, hline.test.ts, line.test.ts, plot.test.ts, constants.test.ts, request.test.ts, ta-backfill.test.ts, parser-fixes.test.ts (1000+ new test cases).
• Missing extend.* enum conributed by @dcaoyuan

Changed

• Type Name Compliance: Renamed internal type constant names to match Pine Script's naming convention exactly (e.g., label.style_label_up → label.style_label_up). Aligned string constants across label styles, line styles, shape types, and size presets so PineTS output is directly compatible with QFChart renderers without manual mapping.

Fixed

• hline consistency : Fixed by @dcaoyuan
• na == na Equality: Fixed na == na to correctly return false in Pine Script (unlike NaN === NaN in JavaScript which is also false, but the equality transpilation path was not applying __eq() consistently in all cases).
• TA Backfill in Conditional Closures: Fixed backfill logic for ta.* window-based functions (sma, highest, lowest, stdev, variance, dev, wma, linreg, cci, median, roc, change, alma) when the function call is inside a conditional block (e.g., if someCondition => ta.sma(...)). Previously, the source-series backfill would fail because the method wasn't being called on bars where the condition was false, leaving the window incomplete.
• TA Function-Variable Hoisting: Fixed ta.obv, ta.tr, and other TA function-variables that behave as both a function call and a variable. These must be evaluated on every bar — even when referenced inside a conditional block — to maintain accurate rolling state. They are now hoisted to the top of the context function.
• RSI Fix: Fixed RSI calculation accuracy for edge cases.
• math.round Compliance: Fixed math.round to match Pine Script's rounding behavior (rounds half away from zero, matching Pine's math.round() semantics rather than JavaScript's Math.round() which rounds half towards positive infinity).
• request.security — syminfo.tickerId: Fixed request.security to correctly parse syminfo.tickerId when it contains the provider prefix (e.g., "BINANCE:BTCUSDT"), stripping the provider ID before lookup.
• request.security — Tuple Returns: Fixed request.security to correctly unwrap and return tuple values from the secondary context.
• Transpiler — Multi-Level Nested Conditions: Fixed transpiler handling of deeply nested if/else if/else chains that span multiple indentation levels.
• Transpiler — IIFE Statements: Fixed handling of already-transformed IIFE (Immediately Invoked Function Expression) nodes to prevent double-transformation.
• Transpiler — Switch/Case Edge Cases: Fixed several edge cases in switch statement transpilation including missing default cases and complex multi-line case bodies.
• color.* Fixes: Fixed several color.* function edge cases for correct RGBA string generation.
