Add parse_kwargs_flat method that ignores argument names for builtin function calls, matching OpenSCAD semantics where names like abs(n=-5) silently work by positional assignment. Only parse_kwargs (modules and user functions) does full named-argument matching.

Also includes test_text.scad font name update. check-in: 9ce4757d0c user: johnfound tags: openscad_lang

Module handlers (_handle_text, _handle_line, _handle_polygon, _handle_square, _handle_circle, _handle_test_internal_occt) now use _leaf_scope instead of manual push_stack/parse_kwargs/pop_stack, matching move/arc/spline pattern.

Fix parse_kwargs: named args no longer advance the positional counter. Positional args now skip parameter slots already claimed by named args, matching OpenSCAD semantics for mixed calls like fn(c=1, 7, 8) -> a=7,b=8,c=1. check-in: 86ae6723a0 user: johnfound tags: openscad_lang

Replaced minimal Git-like reference with detailed Fossil command tables covering status, file ops, committing, history, and remote operations. Added key Fossil concepts vs Git section and explicit warnings about non-existent Git commands (no fossil log, no staging area, etc). check-in: cc3ecb0bca user: johnfound tags: openscad_lang

Module handlers (_handle_text, _handle_line, _handle_polygon, _handle_square, _handle_circle, _handle_test_internal_occt) now use _leaf_scope instead of manual push_stack/parse_kwargs/pop_stack, matching move/arc/spline pattern.

Fix parse_kwargs: named args no longer advance the positional counter. Positional args now skip parameter slots already claimed by named args, matching OpenSCAD semantics for mixed calls like fn(c=1, 7, 8) -> a=7,b=8,c=1.

- Add SCLCapture class for collecting child shapes into compound - Add capture('name') { ... } module to store geometry in parent scope - Add 8 inspection functions: bbox_min, bbox_max, volume, surface_area, centroid, num_faces, num_vertices, num_edges - Add tests/lib/testing.scad with check_approx() function using norm() - Refactor 7 test files to use capture+assert(check_approx(...)) with analytical expected values instead of echo-only verification - Fix rotate() with no args: call ctx.rotate() to produce identity transform so capture() can store the resulting shape - test_capture.scad, test_rotate_openscad.scad, test_multmatrix.scad, test_linear_extrude_center.scad, test_resize.scad, test_fn_threshold.scad, test_import_center.scad check-in: b2b2730f61 user: johnfound tags: openscad_lang

- When a is a vector (Euler angles), v is now properly ignored with warning - When v is passed without a, emit warning (rotation on undef is meaningless) - Rewrite _handle_rotate: three clear branches (vector a, scalar a, no a) - Add tests/test_rotate_openscad.scad: 13 test cases verified against OpenSCAD check-in: 8a1ea30ab8 user: johnfound tags: openscad_lang

- Fix rotate_module_definition: add 'a' parameter alongside 'v' (was only 'v'), remove dual-path arg handling in _handle_rotate. rotate(45) = Z-rotation, rotate(90,[1,0,0]) = axis rotation, rotate([0,0,45]) = Euler angles.

- Add _module_scope context manager: block parsed in clean sandbox frame, sandbox popped BEFORE kwargs parsed. Prevents module args leaking to children.

- Add _leaf_scope context manager for leaf modules (no block, no context).

- Refactor 21 block+kwargs handlers to _module_scope: translate, rotate, mirror, scale, multmatrix, resize, color, loft, union, intersection, difference, hull, minkowski, offset, group, render, projection, linear_extrude, rotate_extrude.

- Fix loft scope leak: sandbox frame was staying on stack during kwargs eval.

- Refactor 10 leaf handlers to _leaf_scope: move, arc, spline, close, fillet, polyhedron, cube, cylinder, sphere, import.

- Add scl_examples/test_args_edge.scad: 11 rotate() edge-case tests. check-in: 937777c08a user: johnfound tags: openscad_lang

- Remove debug_parser=False, debug_expr_en=False, debug_expr() and all 38 if-debug_parser guards (block handlers, profile primitives, simple shapes, import, eval_scope). Net -121 lines in scl.py. - Rename color_module_definition param v -> c (OpenSCAD API). - Restructure _handle_color: parse_block before parse_kwargs in separate stack frames to prevent module args leaking into children. - Update AGENTS.md and docs/scl.md accordingly. check-in: edaf51fe12 user: johnfound tags: openscad_lang

- Add xmin/ymin/xmax/ymax (ink bbox coordinates) to TextShapeResult so Python can use them directly without recomputing via brepbndlib - _get_text_metrics(): call shape_text() directly instead of going through _make_text_shape(), use pen advance for advance (was incorrectly using bbox width, which is always <= pen advance) - _make_text_shape(): fix valign formulas — use ymax/ymin from bbox instead of h (bbox height). valign=bottom was identical to valign=top (copy-paste bug: both used dy=-h) - Update AGENTS.md: document new bbox methods on TextShapeResult check-in: dedfb4e315 user: johnfound tags: openscad_lang

- Replace nanobind with SWIG 4.4.1 (same version as pythonocc) for Python bindings - TextShapeResult: convert from plain struct to proper C++ class with private data (m_shape, m_width, m_height) and public const methods (shape(), width(), height(), is_null()). shape_text() is a friend function. - Remove BRep serialization hack (C++ no longer writes BRepTools::Write string) - TopoDS_Shape typemap: use SWIG_TypeQuery() for runtime type lookup instead of compile-time SWIGTYPE_p_TopoDS_Shape — avoids overwriting pythonocc's clientdata in shared SWIG runtime (fixes ShapeType AttributeError) - __init__.py: thin re-export (import OCC.Core.TopoDS + re-export from _swig), no manual wrapper classes - Remove nanobind dependency from pyproject.toml - Simplify build.sh: use pip install instead of cmake+manual copy - Delete rebuild.sh, _bcad_text_shaper.map (no longer needed) - Fix OutlineContext memory leak: destructor closes current wire, cb_move_to allocates new wire (was previously leaking on every move_to) - Update scl.py consumer: result.shape -> result.shape(), result.width -> result.width() - Update AGENTS.md: document SWIG binding pattern, TextShapeResult class API check-in: b55c3b529a user: johnfound tags: openscad_lang

- New C++ extension (cpp/bcad_text_shaper/) using HarfBuzz for shaping, FreeType for outlines, OCCT BRepBuilderAPI_MakeFace for faces - Proper RTL (Arabic, Hebrew), CJK, ligatures, kerning, vertical text - Auto-detect direction/script from text content via HarfBuzz APIs - Face orientation fix: ShapeFix_Face + BRepAdaptor_Surface normal check - Space handling: pen advance before glyph skip so spaces count in width - BRep serialization: C++ writes BRepTools::Write, Python deserializes - em parameter: matches OpenSCAD effective_size = em * 72.0 / 100.0 - direction/language/script/em params added to text() module definition - direction default changed from 'ltr' to '' for auto-detect (OpenSCAD compat) - spacing parameter now actually passed through (was silently ignored before) - 37 tests passing (12 basic + 25 exotic scripts) - AGENTS.md documented with full API and implementation details check-in: f414607b31 user: johnfound tags: openscad_lang

- text() module: renders text as 2D geometry via OCCT StdPrs_BRepFont font resolution via fc-match, default Liberation Sans supports size, font, halign, valign, spacing parameters creates proper child SCLPart3 context (fixes linear_extrude integration) - textmetrics() builtin: returns position, size, ascent, descent, offset, advance - fontmetrics() builtin: returns nominal/max ascent/descent, interline, font info - expr_dot extended for dict access (tm.size[0], fm.nominal.ascent) - 12 test cases all PASS check-in: d48ee6fbf1 user: johnfound tags: openscad_lang
