From 7731862e4b49f4e8f26722392c638c94c1531f00 Mon Sep 17 00:00:00 2001 From: alaa-eddine Date: Fri, 6 Mar 2026 14:12:06 +0100 Subject: [PATCH 1/6] =?UTF-8?q?Fix=201=20=E2=80=94=20Array=20pattern=20sco?= =?UTF-8?q?ping=20crash=20(StatementTransformer.ts):?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The arrayPatternElements set in ScopeManager is global (not scoped per function). When a function like calcFibLevels has local variables (fib236, priceRange, etc.) that share names with destructured tuple results in the outer scope, they were falsely flagged as array pattern elements. Fix: Added a shape guard — isArrayPatternVar is only true when decl.init is a computed MemberExpression (the _tmp_0[0] pattern from the AnalysisPass destructuring rewrite). This ensures same-named local variables in functions are processed normally. Fix 2 — Missing barmerge namespace (settings.ts): barmerge.gaps_off / barmerge.lookahead_off (used in request.security()) were not in the CONTEXT_BOUND_VARS list, so the transpiler didn't map them to the runtime context. Fix: Added 'barmerge' to the list. Fix 3 : MemberExpression handler: Skip recursion into context-bound namespace identifiers (mirroring the MainTransformer behavior) — these are namespace objects, not series variables Identifier handler: Added safety check to skip addArrayAccess for namespace identifiers that are objects of MemberExpressions Fix 4 : Added bounds checking — returns NaN (Pine's na) for negative or out-of-bounds indices instead of undefined. Test Results 1041 tests pass, 0 failures pressure-zone-analyzer.pine runs successfully (both stripped and full versions with ================================ Fixes Applied 1. Transpiler bug: Namespace identifiers in for-loop test conditions get $.get() wrapping File: PineTS/src/transpiler/transformers/StatementTransformer.ts Problem: In the for-loop test condition walker, the MemberExpression handler was unconditionally recursing into the object of namespace method calls (like math.min, array.size), which caused the Identifier handler to wrap namespace objects with $.get(). This turned correct math.min(array.size(...)) into broken $.get(math, 0).min($.get(array, 0).size(...)). Fix: Two changes: MemberExpression handler: Skip recursion into context-bound namespace identifiers (mirroring the MainTransformer behavior) — these are namespace objects, not series variables Identifier handler: Added safety check to skip addArrayAccess for namespace identifiers that are objects of MemberExpressions 2. Runtime crash: array.get() with out-of-bounds index File: PineTS/src/namespaces/array/methods/get.ts Problem: array.get(arr, -1) returned undefined (native JS behavior), causing crashes when accessing UDT properties like .strength on the result. Fix: Added bounds checking — returns NaN (Pine's na) for negative or out-of-bounds indices instead of undefined. Test Results 1041 tests pass, 0 failures pressure-zone-analyzer.pine runs successfully (both stripped and full versions with request.security) =========================== 1. While-loop test condition hoisting bug (the crash fix) Problem: while array.size(zones) > maxZones had array.size() hoisted to a temp variable outside the loop, making it a one-shot evaluation → infinite loop → crash on undefined.zoneLine Root cause: No WhileStatement handler in MainTransformer.ts, so the default walker let the CallExpression handler hoist calls from the test condition Fix: Added WhileStatement handler to MainTransformer.ts and rewrote transformWhileStatement in StatementTransformer.ts with proper call/member/identifier handling and suppressed hoisting 2. For-loop namespace wrapping (from previous session) math.min(array.size(...)) in for-loop tests was incorrectly wrapped as $.get(math, 0).min(...) Fixed by skipping addArrayAccess for context-bound namespace identifiers 3. barstate.isconfirmed (from previous session) Was checking last bar's close time via closeTime[length-1] instead of current bar Fixed to use closeTime.data[context.idx] (raw array access on the Series) 4. str.tostring format patterns (from previous session) Added support for "#", "#.#", "#.##", named formats 5. array.get bounds checking (from previous session) Out-of-bounds access now returns NaN instead of undefined --- docs/api-coverage/pinescript-v6/types.json | 58 ++-- docs/api-coverage/types.md | 58 ++-- src/namespaces/Barstate.ts | 14 +- src/namespaces/Str.ts | 53 +++- src/namespaces/array/methods/get.ts | 6 + src/transpiler/settings.ts | 3 + .../transformers/MainTransformer.ts | 4 + .../transformers/StatementTransformer.ts | 72 ++++- tests/namespaces/array/bounds-check.test.ts | 166 +++++++++++ tests/namespaces/barstate.test.ts | 186 +++++++++++++ tests/namespaces/constants.test.ts | 51 +++- tests/namespaces/plot/plot.test.ts | 27 ++ tests/namespaces/str-format-patterns.test.ts | 259 ++++++++++++++++++ tests/transpiler/for-loop-namespace.test.ts | 140 ++++++++++ tests/transpiler/pinescript-to-js.test.ts | 26 ++ tests/transpiler/scope-edge-cases.test.ts | 73 +++++ tests/transpiler/while-loop-hoisting.test.ts | 156 +++++++++++ 17 files changed, 1275 insertions(+), 77 deletions(-) create mode 100644 tests/namespaces/array/bounds-check.test.ts create mode 100644 tests/namespaces/barstate.test.ts create mode 100644 tests/namespaces/str-format-patterns.test.ts create mode 100644 tests/transpiler/for-loop-namespace.test.ts create mode 100644 tests/transpiler/while-loop-hoisting.test.ts diff --git a/docs/api-coverage/pinescript-v6/types.json b/docs/api-coverage/pinescript-v6/types.json index 56cede3..c5ab518 100644 --- a/docs/api-coverage/pinescript-v6/types.json +++ b/docs/api-coverage/pinescript-v6/types.json @@ -31,10 +31,10 @@ "backadjustment.on": true }, "barmerge": { -
