# Description
We want to ignore everything on this path so that the build uses its own
dependencies rather than picking up, e.g., the wrong version of libpng
just because that's what someone has in their MacPorts.
This fixes https://github.com/OrcaSlicer/OrcaSlicer/issues/10460
## Tests
I confirmed that this patch fixes the build (`./build_release_macos.sh
-x`).

Flushing volumes only apply to SEMM and BBL printers. Multi-tool printers don't perform filament purging between tool changes, so the zero-volume warning was being incorrectly triggered.
# Description
Reverted PR #12191 and #12777 and added new fixes. This also resolves an
issue where, in some cases, the sliced result was immediately
invalidated after the first slicing.

# Description
Previously, wipe tower behavior was determined by the printer model.
In this PR, we introduced an option that lets users choose which wipe
tower type to use.
BBL printers remain hardcoded to Type 1. Qidi profiles default to Type
1.
This may be useful for users with a filament-cutter-based system
(similar to Bambu printers) who want to use similar configurations—they
can select the "Type 1" wipe tower. That said, Wipe Tower Type 2 is
generally recommended for all printers, whether they use a typical MMU
setup, a filament cutter, or a tool changer.

The check_profiles workflow used gh pr comment directly, which fails for
fork PRs due to read-only GITHUB_TOKEN. Split into artifact upload +
workflow_run pattern so comments post with proper write permissions.
## FIXES
• Corrects area height on windows while using 125% and 175% scaling. it
shows scrollbar when it incorrectly set. i have used directly size of
combobox this time instead static number
## IMPROVEMENTS
• Removes restriction for restarting orca when setting changed
# Description
Add the localization/ directory to the Flatpak source list so
run_gettext.sh can compile .po files into .mo translations.
Replace LC_ALL=C.UTF-8 with LC_NUMERIC=C in the entrypoint script to
preserve the user's language settings while still preventing
decimal-separator parsing issues.

This pull request fixes the bug where Orca Slicer enters an infinite
loop when a density of zero is introduced for the top layer solid infill

/>
Note: For bottom solid infill, this is not a problem because the minimum
density is 10%.
Makes sure all non-bbl printers go through the same filament reordering
code so custom filament sequence is properly handled, while skipping the
filament grouping part by mapping all filaments to group 0.
This is the same method used by BBL printer to calculate the optimal
filament grouping so should be robust.

Happy Hare now writes mmu lane data to the moonraker db similar to AFC,
so we can normalize to the one implementation. For now, i've just
re-ordered it so that the moonraker db is checked first. I want this
because I've actually updated the happy hare data to include more data
than we had access to via the "mmu" object. For happy hare we now have
access to vendor name, which we can eventually use to further fine tune
the auto-matched filament preset.

# Description
Qidi printers run Klipper and we don't want arc fitting enabled for
these.
This is wrongly enabled in QidiStudio as well, likely where these
profiles originated.
With certain irrational beam interlocking parameters, it will take a few
minutes to complete the interlocking generation; even worse:
cancellation doesn't work once it started.
This PR fix that by adding cancellation check inside some of the most
time consuming loops so it can be stopped ASAP.
Also cherry picked a sanity check from
https://github.com/bambulab/BambuStudio/pull/9925 by @mpaperno. Thanks!
The following test project (which was modified from the upper PR by
@mpaperno) took me more than 90s to complete with 0.1mm beam width:

# Description
I was just building the project and checked out the CMakeLists to see if
there are some optional features I can disable to speed up compilation
and tripped on this chinese comment.
This just translates the comment to English for consistency
Previously, wipe tower behavior was determined by checking if the printer
was a QIDI vendor. This introduces a configurable enum (Type 1 / Type 2)
so any printer can select its wipe tower implementation. BBL printers
remain hardcoded to Type 1. Qidi profiles default to Type 1.
# Description
The wipe tower config position (wipe_tower_x/y) could be outside the plate boundary (e.g. default y=250 on a 200mm printer). No constraint was applied at slice time, so the tower was generated out-of-bounds.

std::map::at() throws std::out_of_range when option.category or
"Basic information" is not present in the tab's category_icon_map,
crashing the app. Replace with a safe find()-based helper lambda
that falls back to an empty string (no icon) when the key is missing.
* Fix GIT_COMMIT_HASH not set in Flatpak builds
The env var check was gated inside the .git directory check, so
Flatpak builds (which exclude .git from the sandbox) always fell
back to "0000000". Lift the env var check to top level and inject
the commit hash into the Flatpak manifest via build-options.env.

Fix hotkeys blocked in Prepare view when notification is shown
Restore SetFocus() in the GLCanvas3D mouse-entering handler so the
canvas reclaims wxWidget keyboard focus whenever the mouse enters it
(provided the main window is active). Without this, clicking a sidebar
control or a UI update triggered by slicing could leave the canvas
without focus, causing hotkeys like Tab to stop working until the user
clicked the canvas or dismissed the notification.

The WipeTower2 code path never called construct_mesh(), leaving
wipe_tower_mesh_data as std::nullopt. GCode export then dereferenced
it unconditionally, triggering an assertion failure / crash.
