From e5d3480fa3b16ba80d8a5c841fd22fcdc11ead2a Mon Sep 17 00:00:00 2001 From: Antigravity Agent Date: Mon, 9 Mar 2026 14:45:21 -0400 Subject: [PATCH] fix: C/C++/C# language support - flows from 0 to 300 on real repos MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - fix(c/cpp): isExported was hardcoded false; now checks static linkage - fix(c/cpp): findEnclosingFunctionId - function name is nested in declarator -> function_declarator -> identifier/qualified_identifier, not a direct 'name' field. All CALLS were sourced from File nodes. - fix(cpp): qualified_identifier methods (ImGui::Foo) were registered as 'Method' nodes but findEnclosingFunctionId returned 'Function' label, causing ID mismatch. Fix sets label = 'Method' for qualified_identifier. - fix(c#): CSHARP_QUERIES used 'simple_base_type' which is not a valid node type in tree-sitter-c-sharp. Query silently failed to compile, producing 0 nodes/flows for all C# repos. Fixed to use correct AST structure: base_list directly contains identifier/generic_name. - fix(builtins): Remove 'open', 'read', 'write', 'close' from BUILT_INS set — these are real POSIX syscalls in C, not Python builtins to ignore. - feat(entry-points): Expand C/C++ entry point scoring patterns (~30 new patterns: _init, _run, handle_, _handler, cmd_, server_, session_, etc.) - feat(cpp): Add tree-sitter query for inline class methods defined inside class body (field_declaration with function_declarator) Results on test repos: - tmux (C): 0 → 300 flows, 0 → 22,686 edges - curl (C): 300 flows, 53,229 edges (verified meaningful) - imgui (C++): 218 flows, 5,476 edges, Method CALLS working - ShareX (C#): 0 → 300 flows, 31,338 edges (was completely broken) --- gitnexus/src/core/ingestion/call-processor.ts | 23 +++++++-- .../src/core/ingestion/entry-point-scoring.ts | 49 +++++++++++++++++-- .../src/core/ingestion/parsing-processor.ts | 22 +++++++-- .../src/core/ingestion/tree-sitter-queries.ts | 7 ++- .../core/ingestion/workers/parse-worker.ts | 40 +++++++++++++-- 5 files changed, 123 insertions(+), 18 deletions(-) diff --git a/gitnexus/src/core/ingestion/call-processor.ts b/gitnexus/src/core/ingestion/call-processor.ts index 9b6dfc3f4..32ee30c38 100644 --- a/gitnexus/src/core/ingestion/call-processor.ts +++ b/gitnexus/src/core/ingestion/call-processor.ts @@ -75,10 +75,26 @@ const findEnclosingFunction = ( current.type === 'async_function_declaration' || current.type === 'generator_function_declaration' || current.type === 'function_item') { // Rust function - // Named function: function foo() {} + // Try direct name field (JS/TS/Python/Rust) const nameNode = current.childForFieldName?.('name') || current.children?.find((c: any) => c.type === 'identifier' || c.type === 'property_identifier');
