Twenty buttons on the CONSTRAIN bar, nine of them exercised. The other eleven were "implemented" in the sense that the kernel builds the right def for them -- which is exactly what was true of Parallel yesterday morning, right up until a user pressed it and got nothing. What a kernel test cannot see is whether the BUTTON is wired to the index its name claims. CON_BTN is 449 + 42*i over a hand-written name list, and it has drifted once already: six buttons were inserted, everything from index 6 on pointed at the wrong control, and nothing caught it for months because no rung pressed past index 5. D13 presses index 6; D14 through D22 press 8 to 19. The map turned out to be intact, which is worth knowing rather than assuming. D12 vertical, D13 equal_radius (its own button, not Equal's promotion), D14 concentric, D15 tangent, D16 midpoint, D17 symmetric (the three-pick form), D18 sym_h, D19 radius, D20 diameter, D21 fix, D22 dist_y. Three are shaped around a specific way the code could be wrong rather than around "does something happen": D20 exists for a factor of two. Diameter wired to the Radius handler gives r = 30 for a typed 30, and nothing on screen looks wrong. D21 -- Fix alone is unfalsifiable: nothing moved, so nothing proves the constraint exists. It only becomes observable when a SECOND constraint would otherwise move the fixed point, so the rung drives the pair to a 70 mm gap and checks which end travels. D14 asserts the radii did NOT change. Concentric is about centres; a solve that also equalised the radii would pass a naive check. D17 failed on its first run and the rung was wrong, not the app: all three entities are free, so the solver is entitled to satisfy the mirror by moving the AXIS instead of the points -- and it did, landing the pair symmetric about x = -8.18. It now measures signed perpendicular distance to the axis where the axis actually is, which is the stronger property anyway. Coverage: 20/20 buttons pressed, up from 9. Ladder 135 -> 177 properties across 43 rungs, all holding. snaporca-l2vm
Design-tab scripts
Everything here supports the parametric Design tab (src/libslic3r/CAD/,
src/slic3r/GUI/CAD/). Nothing here is needed to build or run OrcaSlicer — these
are the development and verification tools for that one feature.
The verb in the name is the role:
build-… |
produce a binary |
start-… |
bring something up and leave it running |
run-… |
run a suite and report pass/fail |
check-… |
one specific assertion, usually driving a live app |
Verification
| Script | What it proves | Needs |
|---|---|---|
run-kernel-tests.sh |
The CAD kernel builds and the Catch2 [CadDocument] tags pass — every case builds a document, recomputes it and asserts on real geometry. Exit 0 is the verification contract. |
Docker only. No display. |
run-all-checks.sh |
Every check below, in one command. The gate before pushing a Design-tab change. | Docker + the GUI container |
check-sketch-engine.py |
A ladder of 2D sketches of increasing complexity, judged on loop count, closure and void attribution rather than on area. | Kernel only |
check-sketch-engine-corpus.py |
The same ladder graded against a systematic sample of real drawings instead of shapes we chose. | Kernel + corpus |
check-gui-sketching.py |
The same profiles drawn the way a person draws them — synthetic mouse gestures and typed values. | Headless GUI |
check-gui-context-menu.py |
That right-click is the pivot of the design gesture, and adapts to what was clicked. | Headless GUI |
check-mcp-sketch.py |
The sketch layer driven over the MCP socket, asserting what decides whether a profile is buildable. | Headless GUI + SNAPORCA_MCP |
run-kernel-tests.sh is the only one CI can run. The rest need a live
application with an OpenGL canvas and synthetic input, which hosted runners do not
have. The kernel suite itself is already in CI by an ordinary route: the cases are
registered in tests/libslic3r/CMakeLists.txt under if (SLIC3R_CAD), so they are
part of libslic3r_tests and run under ctest on every platform like any other
unit test. This script exists for the local loop, where it is a two-minute round
trip instead of a full application build.
Build and run
| Script | Purpose |
|---|---|
build-gui.sh |
Build the GUI binary in a throwaway container, writing into the build-cache volume the long-lived GUI container reads. |
build-gui-incremental.sh |
Incremental build against the deps-baked image, for a fast edit/compile loop. |
start-headless-gui.sh |
Bring the app up on a headless X display (Xvfb + a window manager), ready to drive or attach to over VNC. |
Two constraints that are not obvious and have each cost a session:
- Never build inside the GUI container. Its baked source tree silently reconfigures the shared build directory and this fork's targets vanish.
- A window manager is required. Without one, windows are never focused, and an unfocused GTK app ignores synthetic keys — which looks exactly like a code bug.
docs/rig_build_traps.md documents these and three more, with symptoms and exact
recovery commands. Read it before debugging a configure or link failure one of
these scripts reports.
