Generate a complete OpenSCAD file from a list of geometry ScadNodes. Multiple objects are wrapped in a union().

Helper: run Lua code and return the collected ScadNodes.

Extract a float from a Lua table by string key.

Register a batch of simple BOSL2 functions onto a Lua table.

Execute LuaCAD code and return the resulting geometries. Returns `Ok(geometries)` on success, or `Err(message)` on failure.

Helper: export via manifold path and assert file is non-empty.

Extract a float from a Lua table by integer key.

Helper: create a CsgGeometry with only a ScadNode (no pre-materialized mesh).

Find the line start and end (including trailing newline) for the line containing `char_idx`.

Build a ScadNode tree from primitives, materialize it via Manifold, and return CsgGroups ready for OpenCSG rendering.

Multiply two column-major 4x4 matrices: result = a * b.

Extract a bool from a Lua table by string key.

Lint Lua source code using selene with LuaCAD's custom standard library. Returns a list of diagnostics, or an error if the code cannot be parsed.

Recursively evaluate a ScadNode tree into a Manifold object. All boolean operations, transforms, and primitives are performed directly by the Manifold

Persist the last opened file path (or clear it).

Run the same pipeline as export_3mf, returning (verts, tris) for inspection.

Export OpenSCAD source to a file.

Extract a 2-element size [w, d] from a Lua table key that holds a sub-table.

Get segments from table: checks "segments" and "fn" keys, returns default otherwise.

Return the axis-aligned bounding box as (min, max) in [x, y, z].

Export geometries entirely via the Manifold library. Walks each geometry's ScadNode tree, performing all boolean operations, transforms, and primitiv

Extract the triangle mesh (vertices + triangles) from a Manifold object.

redeclared from opencsg.h

An icon button: a small square button with a Lucide icon painted inside. Returns the `Response` so callers can chain `.on_hover_text()` / `.clicked()`

Format a Lua value as an OpenSCAD argument string fragment.

Return a reference to the mesh, materializing it first if necessary.
