* feat(extract): add Pascal/Delphi language support Adds full AST extraction for Pascal and Delphi source files using tree-sitter-pascal (https://github.com/Isopod/tree-sitter-pascal). Supported file extensions: .pas, .pp, .dpr, .dpk, .inc Extracted nodes: - File node (the .pas file itself) - unit / program / library declarations - class, interface, and helper type declarations - procedure and function implementations Extracted edges: - file --contains--> module - module --imports--> dependency (via uses clause, resolved to path-based IDs) - class --inherits--> base class / interface - class/module --contains/method--> procedure or function - procedure --calls--> procedure (in-file call resolution) Key design: uses clause targets are resolved to path-based node IDs by scanning all Pascal files under the project root (_pascal_project_root + _pascal_resolve_unit helpers). This avoids dangling import edges that result from resolving bare unit names like "SysUtils" to IDs that never match any file node. Bare procedure calls (e.g. `Reset;` without parentheses) are detected by inspecting statement nodes whose sole named child is an identifier, in addition to the standard exprCall nodes used for calls with arguments. Requires: pip install tree-sitter-pascal (https://github.com/Isopod/tree-sitter-pascal) If not installed, extract_pascal returns {"nodes":[], "edges":[], "error": ...} so the rest of the pipeline is unaffected.

The extractor parses `object Name: TClassName ... end` blocks to build a containment graph of form components, and captures `OnXxx = HandlerName` event bindings as `references` edges (context: "event") linking each component to its handler procedure. extract_lazarus_package() — .lpk (Lazarus Package files) .lpk files are XML package definitions. The extractor reads the package name, required package dependencies (→ imports edges), and listed unit files (→ contains edges). Unit names are resolved to path-based node IDs via _pascal_resolve_unit so they connect to the same nodes produced by extract_pascal on .pas files. Both extensions added to CODE_EXTENSIONS in detect.py and to _DISPATCH. 13 new tests in test_pascal.py cover both extractors. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(pascal): fix dangling inherits-edge targets and capture all base classes The declType/typeref handler built inherits edge targets with _make_id(_read(child)) — just the bare class name. But class nodes use _make_id(stem, type_name), so targets never matched, making the entire class hierarchy invisible in the graph. Add _pascal_class_stem_cache and _pascal_resolve_class(): strips the conventional T/I prefix, locates the defining file by stem lookup (same cache mechanism as _pascal_resolve_unit), and returns the correct _make_id(file_stem, class_name) ID. RTL/unresolvable bases (e.g. TObject) fall back to _make_id(bare_name) with an explicit stub node, following the same pattern as the Python extractor. Also remove the `break` that stopped after the first typeref, so all parents are captured (e.g. class(TBase, IInterface)). Extend test_pascal_no_dangling_edges to also assert that within-file edge targets (contains, method, inherits, calls) resolve to real nodes. * feat(extract): add Delphi .dfm form file support Adds extract_delphi_form() for Delphi Form files (.dfm), which use the same `object Name: TClassName ... end` text syntax as Lazarus .lfm files. Binary .dfm files (FF 0A magic header) are skipped gracefully with an informative error message so the pipeline is unaffected. Text .dfm files are parsed identically to .lfm: component containment (`contains` edges) and event handler references (`references`, context "event"). Adds .dfm to _DISPATCH and CODE_EXTENSIONS. 10 new tests in test_pascal.py, including a regression test for the binary-format detection. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Add .lpr extension and fix removesuffix in Pascal extractor Address review feedback from @safishamsi: - Add .lpr (Lazarus program file, identical syntax to .dpr) to _DISPATCH in extract.py and CODE_EXTENSIONS in detect.py so Lazarus project entry points are indexed. Completes the promised Lazarus IDE support. - Replace rstrip("()") with removesuffix("()") in the call-resolution dict comprehension for precise suffix removal (rstrip strips individual characters, not the literal string "()"). - Add .lpr assertions to test_pascal_dispatch_registered and test_pascal_detect_extensions_registered.
