Pull request overview
Refactors the model rendering API to support a mockable Cairo abstraction (ICairoShim), enabling unit tests to verify drawing behavior without a real cairo_t* and reducing direct coupling between rendering code and Cairo.
Changes:
- Added
ICairoShiminterface and a concreteCairoShimCairoadapter that forwards to native Cairo. - Introduced
draw(ICairoShim&)(and related helper overloads) acrossItemand many subclasses, often delegating to existingcairo_t*implementations viacairoContext(). - Updated
Wireand various UI/model items to support the new shim-based draw path.

Wire::draw(ICairoShim&, ...) is declared here, but ICairoShim is not declared or included in this header. This will fail to compile when including wire.h on its own. Add #include "ICairoShim.h" (or class ICairoShim; forward declaration inside namespace minsky) before the Wire class definition.

This ICairoShim-based implementation still calls raw cairo_* APIs (cairo_identity_matrix, cairo_translate, cairo_rotate, cairo_user_to_device) even though equivalent methods exist on ICairoShim. That bypasses the shim and prevents mocks from observing these operations. Use cairoShim.identityMatrix()/translate()/rotate()/userToDevice() here instead of calling through the underlying cairo_t*.

This new draw(ICairoShim&) path uses cairo_move_to / cairo_show_text directly. Since ICairoShim already exposes moveTo() and showText(), calling the raw Cairo APIs here defeats the testability goal of the shim (mocks won't see the calls). Route these through cairoShim instead.

cairoShimCairo.h is included from the model layer, but this file doesn't reference CairoShimCairo (only ICairoShim). Keeping this include adds an unnecessary engine dependency and increases coupling/compile time. Prefer including only the interface header (or relying on item.h’s ICairoShim include) and remove this include if unused.

Before merging this PR to main, we need to have fully abstracted cairo from all Item instances - no sneaky going around the back by downcasting to CairoShimCairo.

VariableBase::draw requires RenderVariable class refactoring to support ICairoShim. RenderVariable is a complex rendering cache that currently stores cairo_t* pointer and uses it throughout. Converting this properly requires:
- Changing RenderVariable to store/use ICairoShim instead of cairo_t*
- Updating all RenderVariable methods to use ICairoShim
- Similar changes to miniPlot rendering
This is a substantial refactoring beyond the draw method itself. Should I proceed with this or is there a simpler approach you'd recommend?

Partially implemented in 15aa917 - Ravel::draw now uses ICairoShim for most operations. CairoRenderer and SVGRenderer still use _internalGetCairoContext temporarily - these rendering classes need their own ICairoShim refactoring.
- Added drawTriangle(const ICairoShim&) overload to cairoItems - Fully implemented SwitchIcon::draw(ICairoShim&) without using _internalGetCairoContext - Fixed variable.h signature to use const ICairoShim& - Added drawUserFunction(const ICairoShim&) declaration for future implementation Co-authored-by: highperformancecoder <3075825+highperformancecoder@users.noreply.github.com>
- Added full drawUserFunction(const ICairoShim&) implementation - Converted most of Ravel::draw to use ICairoShim methods - Updated userFunction.h and dataOp.h to use new drawUserFunction overload - Remaining: DrawBinOp, CairoRenderer, SVGRenderer still need cairo_t* temporarily Co-authored-by: highperformancecoder <3075825+highperformancecoder@users.noreply.github.com>
Significant progress made. Successfully removed _internalGetCairoContext() from main draw logic: Fully converted (no _internalGetCairoContext in draw methods):
Partially converted (main logic uses ICairoShim, helpers still need work):

OK the pull request is now passing the regression suite. |
- PhillipsStock now uses ICairoShim methods for its own drawing (rectangles, fills) - Calls StockVar::draw(cairoShim) which internally still uses _internalGetCairoContext - Reduced _internalGetCairoContext usage from 11 to 10 locations - PhillipsStock's own drawing logic now fully abstracted Co-authored-by: highperformancecoder <3075825+highperformancecoder@users.noreply.github.com>
Started with PhillipsStock in 91caf2d. Converted its drawing operations to use ICairoShim methods (setSourceRGBA, rectangle, fill). Reduced _internalGetCairoContext usage from 11 to 10 locations. Remaining items prioritized by complexity:

- Added virtual iconDraw(const ICairoShim&) to OperationBase interface - Generated ICairoShim overloads for all 76+ Operation<Type>::iconDraw implementations - Updated OperationBase::draw to call iconDraw(cairoShim) instead of iconDraw(cairo) - Updated IntOp::draw to use DrawBinOpShim instead of DrawBinOp - ICairoShim iconDraw methods currently delegate to cairo_t* versions (migration step) - Removed direct _internalGetCairoContext usage from OperationBase::draw - IntOp still uses _internalGetCairoContext for RenderVariable (tracked separately) - Reduced _internalGetCairoContext from 10 to 9 direct usages in draw methods Co-authored-by: highperformancecoder <3075825+highperformancecoder@users.noreply.github.com> Agent-Logs-Url: https://github.com/highperformancecoder/minsky/sessions/b21274df-9484-488b-90c3-daceed36cadc
Implemented in e77029b. Added iconDraw(const ICairoShim&) interface to OperationBase with overloads for all 76+ Operation types. Updated OperationBase::draw and IntOp::draw to use the new interface. IconDraw implementations currently delegate to cairo_t* versions as a migration step, but the draw() methods themselves no longer directly use _internalGetCairoContext. IntOp also now uses DrawBinOpShim instead of DrawBinOp.
Continued in e77029b - completed IntOp and OperationBase refactoring. |
…rformancecoder/minsky into copilot/refactor-item-draw-method
plotwidget requires exposure to the cairo API - need to refactor EcoLab to use CairoShim also.
will need a deeper refactor of text rendering interface later on.

- Around line 153-159: In CairoShimCairo::renderSVG the MXE branch calls
rsvg_handle_render_cairo(&svg, cairo) using a nonexistent local variable; change
the call to use the SVGRenderer member handle by invoking
rsvg_handle_render_cairo(svgRenderer.svg, cairo) (no &), so the function uses
the existing svgRenderer.svg pointer consistent with the other calls in
renderSVG.
In `@engine/slider.h`:
- Line 22: Replace the C header include with the C++ header and use the std
namespace function: change the include from <math.h> to <cmath> and update any
uses of isfinite to std::isfinite (e.g., where the slider code checks numeric
finiteness). Ensure any using directives or overloads don't shadow std::isfinite
and include <cmath> at the top of engine/slider.h so the compiler resolves
std::isfinite correctly.

- Line 20: The generated type ICairoShim is declared but not exported causing
declaration emission to fail; update the code generator so that the generated
declaration for the shim is exported (e.g., produce "export class ICairoShim {}"
instead of "class ICairoShim {}") so all consumers of Item.draw(),
Item.displayTooltip(), Item.drawPorts(), Item.drawResizeHandles(),
Item.drawSelected() and exported methods on OperationBase, GodleyIcon, Group,
PhillipsStock, Ravel, etc. reference an exported ICairoShim; ensure the
generator emits the export keyword wherever ICairoShim is generated and rerun
generation to include the exported symbol in the library's .d.ts output.
In `@model/ICairoShim.h`:
- Around line 99-104: The call in renderSVG is passing an undefined variable
`svg` to rsvg_handle_render_cairo; update that call to use the SVG handle from
the SVGRenderer parameter (use `svgRenderer.svg`) so it matches the other
accesses (e.g., the calls on the surrounding lines that use `svgRenderer.svg`),
ensuring the renderSVG implementation calls
rsvg_handle_render_cairo(svgRenderer.svg, cairo).
In `@model/phillipsDiagram.h`:
- Around line 56-57: The declaration void draw(const ICairoShim&); in class
PhillipsFlow should be changed to void draw(const ICairoShim&) const override so
it properly overrides Item::draw(const ICairoShim&) const; also update the
corresponding definition in phillipsDiagram.cc (the PhillipsFlow::draw(const
ICairoShim&)) to include the trailing const and add override to the declaration,
ensuring signature matches the base virtual method and enables polymorphic
dispatch.
In `@model/plotWidget.cc`:
- Around line 219-223: The current PlotWidget::draw(const ICairoShim& cairoShim)
performs a dynamic_cast to CairoShimCairo which can throw; either make the
overload Cairo-only by changing the signature to accept a const CairoShimCairo&
(and update the corresponding call sites) OR add a virtual accessor to
ICairoShim (e.g., getCairoContext() or similar) that returns the underlying
cairo context and implement it in CairoShimCairo, then call that virtual instead
of dynamic_cast; apply the same consistent change to all other affected
functions (e.g., model/godleyTableWindow.cc, operation.cc, wire.cc, sheet.cc,
variable.cc, ravelWrap.cc, intOp.cc, group.cc) so no code performs dynamic_casts
to CairoShimCairo.

Continues ICairoShim abstraction by eliminating
_internalGetCairoContext()from drawUserFunction and substantially refactoring GodleyIcon, Group, PhillipsStock, OperationBase, and IntOp draw methods to use the abstract interface. Adds comprehensive type-safe SVG rendering support to ICairoShim.Changes
