# Description
Python plugins currently have no way to localize their own dialogs to
match the app: the UI language is stored in `OrcaSlicer.conf`, which the
plugin audit hook deny-lists by design (the file sits next to cloud
secrets), and the host API exposes no app info. As a result, localized
plugins have to guess the language from the OS locale, which does not
always match the slicer UI (and the embedded interpreter often gets no
`LANG` at all in GUI sessions).
This PR adds a minimal read-only accessor:
```python
orca.host.app_language() # -> "en_US", "ru_RU", ...
```
It returns `GUI_App::current_language_code_safe()` — only the language
code string, nothing else from the config, so the audit-hook security
model is untouched.
No breaking changes; one file, +10 lines.
# Screenshots/Recordings/Graphs
(screenshots of the test dialog will be attached below)
## Tests
- Built on macOS (arm64, Ninja) with this change — compiles clean.
- Ran a minimal script-capability plugin calling
`orca.host.app_language()` on a system with Russian UI: the dialog shows
`'ru_RU'`.
- Guard before GUI init follows the same exception pattern as the
neighbouring `plater()`/`preset_bundle()` accessors.

With the gap wall on a multi-tool printer, quantize the ram band up to its
whole reserved rows (as the BBL tower does for the old-tool purge) and start
CP TOOLCHANGE WIPE at the left-edge boundary on a fresh row below it instead
of continuing from wherever the ram serpentine ended. The entry scrub then
runs at the wall gap on ram toolchanges too, and the wipe box is whole rows,
so it is filled completely like the no-ram case. SEMM and skip-points-off
behavior is unchanged.
The entry scrub now matches the BBL tower's toolchange_wipe_new sequence:
after the ironing drag the retracted nozzle runs a dry expanding-square
spiral centred on the wall-gap entry point before resuming the purge row.
The spiral runs whenever the gap wall is on (disable per filament via
filament_tower_ironing_area = 0); WipeTower2 no longer reads
prime_tower_flat_ironing.
Without ramming, each purge block reserved one wipe pitch more than its
rows occupy (ceil+1 rounding plus the ram-geometry start offset), and the
wipe began a full pitch inside the block, leaving a blank band of exactly
two pitches between adjacent blocks. Plan the block as whole wipe rows,
start the first row so the row lattice continues across the block
boundary, and fill the reserved box instead of stopping at the ordered
volume, mirroring how the BBL WipeTower keeps planned depth identical to
printed rows. Ram-printing toolchanges (SEMM with ramming enabled,
multitool ramming) are unchanged.
The planner reserved ramming rows gated only on enable_filament_ramming and
sized them with the SEMM 0.25s time step, while toolchange_Unload rams on
(semm && enable_filament_ramming) || filament_multitool_ramming with the
multitool time step. Disabling multitool ramming therefore left ~3 unprinted
rows per toolchange as blank bands in the tower. Without ramming the first
wipe line also needs reserved depth of its own (it no longer rides the last
ramming row), plus the y_step/2 offset the wipe start inherits from the
ramming start position - otherwise the tightened boxes truncate the ordered
purge at the box edge.
Plugins have no way to localize their own dialogs: the UI language lives in
OrcaSlicer.conf, which the plugin audit hook deny-lists because the file sits
next to cloud secrets. Add a read-only host accessor that returns just the
language code (current_language_code_safe), so plugins can match the app
language without touching the config file.
Port the BBL tower's entry line ironing: extrude the first 3 mm of the
purge, retract, drag the nozzle 1.5x back out through the wall gap at
F600, creep back at F240 and unretract, so the toolchange start blob
ends up in the gap instead of on the wall. Fires only when the purge
starts at the left-edge entry heading right (in-place toolchangers);
SEMM ram/cooling wipes start mid-box and the priming line has no wall,
so both keep their previous output.
* For dialog without explicitly `SetMinSize`, we should use `SetSizerAndFit` instead, otherwise the dialog will not show correctly on GTK3. (OrcaSlicer/OrcaSlicer#14561)
- and if `SetSizer` is called before the full layout has been built, then an extra `SetSizeHints` should be called before layout/fit so the min size can be properly set automatically based on children's min sizes accordingly.
* Fix GTK3 dialog min size: SetSizer → SetSizerAndFit for dialogs without explicit SetMinSize
Replace SetSizer() with SetSizerAndFit() in 11 dialog constructors that
neither call SetMinSize() nor SetSizeHints(), ensuring proper minimum
size propagation from child widgets on GTK3.
SetSizerAndFit internally calls sizer->SetSizeHints(window), which
sets the window's minimum size based on children — the same fix
applied to ProjectDropDialog in 8a7662083e.
Also drop sizer->Fit(this) calls where present, since they only
resize but don't set the min size hint needed by GTK3.

On multi-tool printers without ramming the tool changes away from the
tower and the entry travel is the tcr's own positioning move, which went
straight across the printed wall. Append the avoid-perimeter path to the
change-filament gcode instead, so the head approaches around the tower
and enters through the wall opening (append_tcr parity).
prime_tower_skip_points was stubbed for Type2 towers: the wall call
hard-coded skip_points=false, the gap cutter received an empty vector,
and append_tcr2 never routed the entry travel. Now the toolchange entry
positions are precomputed from the finalized plan, the wall is cut open
at each entry, and the entry travel approaches around the tower bounding
box through the opening when it starts outside the tower. The geometry
helpers are re-synced with the BBL versions (add_extra_point guards,
per-point side selection). The cone wall keeps its separate path, where
the option stays inert.
Behavior change: non-BBL towers now honor the (default-on) checkbox with
gap walls and routed entries; with the option off the output is
unchanged, and the BBL tower path is untouched.
A boolean cut whose tool misses the target is a perfectly legal
operation: OCCT reports IsDone(), the shape comes back unchanged, and the
feature lands in the recipe reporting ok:true. Driving the MCP socket,
that produced two consecutive {ok: true, bodies: 1, error: ''} responses
for a hole that was never drilled -- same viewport, same 46939.11 mm3 --
and the tree grew two Hole features that will never cut anything. A
caller, an agent especially, has no signal at all that the thing it asked
for did not happen.
Measure the volume across the op in route_feature's in-place branch and
refuse the no-op. Only for removals: Hole, Thread, and Extrude / Revolve
/ Sweep / Loft in Cut mode. Everything else may legitimately leave the
volume alone -- a Transform certainly does. The tolerance is relative,
because an absolute epsilon is wrong across the mm-to-metre range of real
parts, and a cut that shaves a numerically invisible sliver is a miss
too. The existing rollback in the MCP actions already preserves the
reason, so a missed hole now answers ok:false with the error and undoes
the feature.
The confusion underneath was not itself a bug: hole's x/y are in the
sketch plane's frame, whose origin is describe_scene's modeling_origin,
and describe_tools documented them only as "number, unit mm". Passing the
world centre put the hole 135 mm clear of the solid. All six x/y params
on hole / hole_styled / hole_standard now say which frame they are in,
since the wrong guess was silent.
Regression test drives the reported failure directly: a hole at x=135 on
a 20x20x20 box is rejected and leaves the body untouched, the same hole
at the origin still removes exactly pi*4^2*20, and a cut-mode extrude
whose profile sits at x=200 is rejected too. 152 cases / 2083 assertions
green on both forks.
snaporca-daf.
Like the BBL tower: the layer's sparse infill, wall, and brim go to the
first toolchange to a non-support/non-soluble filament, or are printed
with the incoming filament before any toolchange. The minimal-purge
clamp now also covers toolchanges that get no finish-layer saving.
Output is unchanged when no support/soluble filament is used.
All 17 single-letter sketch shortcuts were dead. The dispatch gate was
circular: the sketch key map was consulted only when
m_viewport->is_sketching() was already true, but is_sketching() is a
whole-session flag whose only riser is begin_sketch(), called from
select_tool() -- which is precisely what every sketch key closure calls.
So the first letter after entering sketch mode fell through to the
feature map, where the keys are Shift+letter, matched nothing, and did
nothing. The mouse worked only because the toolbar flyout row reaches
select_tool() directly, bypassing the gate.
Which key MAP applies is a question about the mode. Split the flag:
'sketching' (live session) still drives undo/redo, Delete and the
section-view branch, where a session genuinely has to exist; a new
'sketch_mode' (m_ui_mode == UiMode::Sketch alone) drives the map choice.
Verified headless end to end, keyboard only: Shift+S, then R draws a
143.4 x 133.7 rectangle on XY reporting 4 degrees of freedom, then F and
L arm Fillet and Line (artifacts/shots/0udb-01..03). Note the toolbar
strip does NOT change when a tool is armed by keyboard -- the family
buttons are flyouts and only show their own pressed state -- so the
pixel diff on that strip, which is how this was originally measured,
reads 0 for a tool that is live. The status line is the surface that
actually reflects the armed tool.
Also fixed, from snaporca-d9i's list: the plane-pick status line said
"press Sketch to draw on it", naming a button that exists only in
Feature mode. It is now mode-aware.
Adds a SNAPORCA_KEYTRACE=1 trace in the CHAR_HOOK printing key, ui mode,
is_sketching, in_text and the focused window's class. It is what
separated "the fix does not work" from "the surface being measured never
moves", and it costs a full GUI build to re-add, so it stays.
snaporca-0ud, partial snaporca-d9i.
Two P0s in the same gesture. Filleting a corner of a parametric rectangle
produced either nothing at all or a sharp corner with a stray arc floating
above it.
Trigger (snaporca-cq2): the only routes that ever reached confirm_op were
finishing the whole sketch and an unsignposted click on empty space.
set_tool() dropped a ready op, so typing a radius or dragging the arrow and
then touching any other tool threw the value away. Commit a ready op on tool
change (before m_mode is reassigned — op_ready() and confirm_op() both switch
on it), commit on Enter in the radius editor, and drop the pending op before
Esc's tool downgrade so Esc still cancels rather than applies.
Substitution (snaporca-pl5): libslvs writes its last Newton iterate into the
params whether or not it converged, and SketchSolver read them back
unconditionally, so every REJECTED solve deformed the sketch. The fillet
ladder tries a deliberately over-constrained rung first (a tangent on each
leg, against the legs' own H/V); it is correctly rejected, but its wreckage
then failed rungs 2 and 3, which solve cleanly on their own. The arc ended up
with no constraints at all, the rigid loop won, and the corner snapped shut.
Measured: from pristine geometry rung 1 gives result=INCONSISTENT with 3 bad
constraints, rung 2 gives dof=6 with the arc's radius intact.
Read the geometry back only on success. try_add_constraints then needs no
"restore" re-solve — the entities still hold the prior solved state.
Kernel suite 151 cases / 2072 assertions green on both forks; the GUI check

The card decides between a single picked edge and a whole face-group from a
viewport pick it never mentioned. With no edge picked the user saw only the
group combo and concluded per-edge rounding did not exist; with an edge picked
the combo still read "All" — the opposite of what Confirm would do.
Adds a Target row that names the actual target and greys the group combo out
while an edge is picked, wired at the same three points Shell already uses:
the selection-changed handler, the re-edit load, and open_tool.

estimate_wipe_tower_polygon reserved the arrange footprint and clamped the
tower X position with the raw prime_tower_width, under-reserving space
whenever the rib wall squares the tower to a different width.
The rib tower is now always square (prime_tower_width is ignored, as the
GUI already implies), carries the rib origin offset like the BBL tower so
the rib tips sit inside the configured position, clamps the rib length to
the tower diagonal, and extends the ribs for short towers.
The CAD sources are meant to be byte-identical across the two forks, with exactly
two permitted divergences: DesignPanel.cpp's flyout plumbing (30 lines — mainline's
DropDown is Item-based where the other fork takes three parallel vectors) and
DesignCanvas.cpp's Bed3D::set_shape signature (16 lines). DesignPanel.cpp had drifted
to 105.
Nothing failed to announce this. The kernel suite does not compile the GUI, and all
four defects are interaction-level, so both forks stayed green while only one of them
had the fixes. The parity diff is what found it.
* combo_append_index and its five call sites. Orca's ComboBox keeps client data in
its own vector, so Append()'s clientData argument never reaches wxItemContainer
and m_clientDataItemsType stays wxClientData_None. GetClientData() opens with a
wxCHECK_MSG, which is an early return — so every read came back NULL and every
caller resolved it to index 0, silently, because 0 is a legal answer. Affects the
rib sketch picker, the sheet-body picker, both mate coordinate-system pickers and
the sweep path picker.
* Wrap(240) over the card labels. wxStaticText never wraps itself, so a one-sentence
hint sets its card's minimum width to the width of the whole sentence and every
control in that card is clipped at the sidebar's right edge.
* Shell and Draft face-label initialisation in open_tool. Both read the face from the
live pick at Confirm time, but only the pick handler wrote their labels, so picking
a face and then opening the card left the card describing one operation while
Confirm performed another.
* SurfaceOffset and ThickenSurface added to build_candidate's negative list. Both read
a sheet body from their own combo and both had it overwritten by the picked solid's
index. The list is a negative one, so a tool that picks its own body breaks by
omission — noted in a comment now.
Also drops a stray <cstdio> left behind by a debug probe.
Verified by building the GUI here for the first time since these landed: 461/461,
liblibslic3r_gui.a links. DesignPanel.cpp is back to exactly 30 divergent lines and
every other CAD file is byte-identical again.

The inline editor special-cased Escape and Skip()ped every other key, so Tab fell
through to wx's default navigation. Its popup frame holds exactly one control, so
focus came straight back to that control with its text re-selected.
Type 60, Tab, 40, Enter — expecting to fill two dimensions — and the 60 is gone: Tab
neither committed it nor advanced, so the 40 just replaced the re-selected text. A
re-selected field is pixel-identical to a freshly opened one, so nothing on screen says
a number was dropped. Tab-to-next-dimension is what Onshape, SolidWorks and Fusion do,
which is exactly why it is the key a user reaches for.
Tab now calls do_commit(), the same path Enter takes; the caller's on_commit is already
what walks to the next dimension. Verified by driving the GUI: 37 Tab 24 Enter now
produces a 37.0 x 24.0 rectangle, where before it produced 24 and a mouse-derived value.

A filleted solid arrived on the plate as a broken model: the slicer reported
"8 non-manifold edges" on an 80x50x12 box with r=3 on all edges, and advised
repairing it in another CAD application -- the exact round trip the Design tab
exists to remove. The same box without the fillet committed cleanly.
Measured rather than guessed. Each of the 8 bad edges is degenerate, both
endpoints the same vertex:
open tri=145 edge=1 face=5 v59(3.000000 3.000000 0.000000) v59(3.000000 3.000000 0.000000)
open tri=538 edge=1 face=6 v87(3.000000 3.000000 12.000000) v87(...)
... one per corner, 8 corners
OCCT triangulates a degenerate surface parameterization with a triangle at the
pole; a corner sphere patch has exactly one. Its two pole nodes are distinct in
the per-face triangulation and collapse to a single vertex when the faces are
welded, leaving a zero-area triangle whose v->v edge can never pair with a
neighbour. its_face_neighbors counts it as open, and the field the object panel
prints as "non-manifold edges" is in fact stats.open_edges.
So the geometry was never wrong -- the B-rep volume matches the Steiner formula
for a box dilated by a ball to 0.016%. Only the bookkeeping was.
Dropping those triangles after the weld removes 8 of 3492 and takes open_edges
to 0. Zero area, so nothing about the shape changes. tri_face is compacted in
the same pass, since it must stay index-aligned with the triangle list that the
face picking and per-body colouring both index into.
Guarded by a new [CadDocument] case that asserts open_edges == 0, no degenerate
triangle survives, and both per-triangle maps still match the triangle count.
The existing suite only ever checked B-rep volumes and areas, which is why a
mesh defect this visible went unnoticed: 150 cases / 2049 assertions green on
both forks.
snaporca-agw
OCCT_LIBS is an explicit single-pass static link order — dependents first, TKernel
deliberately last. The CAD block appended its two extra toolkits to the END of that list,
which puts them after everything they depend on:
list(APPEND OCCT_LIBS TKFillet TKOffset)
TKOffset references BRepAlgo_Loop, and nm against the built deps prefix shows TKBool is the
only toolkit that defines it (TKTopAlgo, TKBO, TKPrim, TKFillet and TKOffset all define it
zero times). TKBool sits first in the list, so a single-pass linker has passed it long before
it reaches the appended TKOffset and will not go back:
libTKOffset.a(BRepOffset_MakeLoops.cxx.o): undefined reference to
BRepAlgo_Loop::BRepAlgo_Loop()
Only one configuration ever objected — the Snapmaker fork Flatpak (aarch64). Ordinary Linux,
macOS and Windows links resolve it regardless, and the mainline fork Flatpaks pass, so six
green platform legs said nothing about whether this list was correct.
Prepended via set() rather than list(PREPEND), which needs CMake 3.15 while this project
supports 3.13.
Worth knowing for later: TKFillet and TKOffset are mutually dependent, 20 symbols needed in
each direction, so a stricter single-pass link could still trip on that pair. It does not on
any current platform, so no --start-group or duplicate entry is added here; if something ever
complains about ChFi or BRepFill symbols, that cycle is the reason.

* feat: add getters/setters for wxInspector plugin access
Add minimal public accessors to DPIAware (set_scale_factor,
set_prev_scale_factor, set_em_unit, force_rescale), Button
(GetStyle, GetType, IsSelected), CheckBox (IsHalfChecked),
TextInput (GetCornerRadius), and LabeledStaticBox
(GetCornerRadius, GetBorderWidth, GetBorderColor, GetScale).
* feat: add wxInspector plugin registration helper
Add RegisterOrcaInspectorPlugins() inline function that creates

The header forward-declares a long list of wx types and omitted wxBoxSizer, wxTextCtrl and
wxListCtrl. All three are used as pointer members only (m_expr_text, m_var_list,
m_parts_hdr, m_hdr_tree_row), so a forward declaration is all they need — but there was
none. Every ordinary build compiled anyway because the wx/panel.h + wx/scrolwin.h chain
happens to pull the real headers in transitively.
The Snapmaker fork Flatpak build (aarch64) has a wx that does not, and it failed outright:
DesignPanel.hpp:511: error: 'wxTextCtrl' does not name a type; did you mean 'wxTreeCtrl'?
DesignPanel.hpp:521: error: 'wxListCtrl' does not name a type; did you mean 'wxFileCtrl'?
DesignPanel.hpp:663: error: 'wxBoxSizer' does not name a type; did you mean 'wxSizer'?
plus a cascade of "m_var_list / m_expr_text / m_parts_hdr was not declared in this scope".
Not an environment quirk: the header was simply not self-contained, which is exactly what
breaks a reviewer building in an unfamiliar configuration. The mainline fork Flatpaks passed
on both arches, so only that one manifest exposed it.
Audited the rest of the header afterwards: every other wx pointer type is either
forward-declared or genuinely included — only wxScrolledWindow and wxWindow are undeclared,
and both come from the real wx/scrolwin.h include.

store_bbs_3mf reaches Model::get_backup_path(), which builds
temporary_dir() + "/orcaslicer_model/" + timestamp. temporary_dir() returns a file-static
that ONLY OrcaSlicer.cpp's startup sets, so in a test binary it is the empty string and the
backup path becomes "/orcaslicer_model/..." — absolute, at the filesystem root. An
unprivileged process cannot create that, so the save returned false and the scenario died
on REQUIRE(store_bbs_3mf(sp)).
This was the SINGLE failure in this fork's Unit Tests — 1 of 566, on Linux x86_64, Linux
aarch64 and macOS arm64 — from CI run 30191490709:
Failed to create backup path "/orcaslicer_model/Sun_Jul_26/08_49_41#5398#1":
boost::filesystem::create_directories: Permission denied [system:13]
It hid because that job had never run to completion on this branch before: every earlier
run was cancelled by the concurrency group first. It also passed on Windows x64, where the
drive-root path is writable, and it passes in the local build container, which runs as root.
Verified against the same defect in the Snapmaker fork by running the built binary as
uid 1000: permission denied before, 4 assertions passing after.

snaporca-tkz, the last quarantined test. Root cause read out of the vendored
source rather than guessed: slvs/constrainteq.cpp, Type::ARC_LINE_TANGENT does
ExprVector ap = SK.GetEntity(arc->point[other ? 2 : 1])->PointGetExprs();
so it dereferences the ARC'S ENDPOINTS. A full circle entity carries only
point[0], its centre. point[1] and point[2] are zero handles, FindById throws
"Cannot find handle", and the process ABORTS rather than failing the solve —
taking every later test in the binary with it. That is also the wrong equation
for a circle regardless: it only makes the line perpendicular to the radius at
an endpoint that does not exist.
CT::Tangent no longer hands a full circle to that constraint. For a circle it
emits PT_LINE_DISTANCE(centre, line) = radius, which is precisely what tangency
to a circle means. Arcs keep the ARC_LINE_TANGENT path they are built for.
One limitation, stated rather than buried: the slvs C API takes a constant
distance and offers no way to reference the circle's radius parameter, so the
radius is captured when the constraint is emitted. That is exact whenever the
radius is fixed or is simply not driven by another constraint in the same
solve, and re-solving restores tangency if something else moves it. Tying them
would need an auxiliary point constrained onto both the circle and the line.
With this and eeca6794e7, both quarantined tests are gone and the exclusion in
kernel-test.sh goes with them. A green run now means the whole CAD suite

Follow-through from eeca6794e7. The header claimed two pre-existing failures
are excluded and named both; the internal-thread case now runs like any other,
so only the solver SIGABRT is left. A comment that lists a test which is no
longer excluded sends the next reader looking for something that is not there.

snaporca-kzy was filed as "internal thread cuts too little material". It does
not. Measured on the test's own fixture, a 40x40x20 box:
plain Ø12 bore removes 2261 mm3
internal thread removes 2157 = 1571 (minor bore) + 586 (groove)
apply_thread bores at the MINOR radius (radius - depth = 5) and then carves the
groove out to radius + depth = 7. A tapped hole therefore keeps the crests
between turns and holds MORE material than a plain clearance hole at the
nominal radius — which is what every real tapped hole does. The test asserted
the opposite, so it was asking for something physically wrong and had been
quarantined for it since it was written.
One hypothesis discarded on the way: that the shortfall was a tessellation
artefact, since chords on a helical surface undercut a concave bore. Exact
BRepGProp::VolumeProperties agreed with the tessellated volume to within
2.5 mm3, so that was not it and is not offered as a hedge.
The reference is now the tap-drill bore the thread actually starts from (Ø10),
against which the groove's 586 mm3 is the meaningful quantity — that is what
"the thread cuts" means. Test re-tagged [CadDocument][thread], so CI covers the
thread path again instead of skipping it.
Also documented the (void)internal in make_thread_profile. It reads like a bug
and is not: the V is the same shape either way and the caller decides, fusing
it onto a shaft or cutting it out of a wall. Someone "fixing" it to point
inward for the internal case would make the groove sweep already-empty bore
space and cut nothing — the exact failure the old comment described.
Suite 148 cases / 2035 assertions, with this test now among them.
