at the placeholder parser.
Implemented a new PlaceholderParser::evaluate_boolean_expression()
functionality to evaluate just a boolean expression using the full
expressive power of the macro processing syntax. This function
will now be used for deciding, which print or filament preset
is compatible with which printer preset.
in a form similar to Perl:
Following expression returns true, if the variable matches the regex:
variable =~ /regex/
Following expression returns true, if the variable does not match the regex:
variable !~ /regex/
The Clipper library is not stable when calcuating offsets of contours
with holes. Replaced a single call of offset2 with offset_ex(offset_ex()).
This is not the most efficient solution, but it fixes this problem.

"Multimaterial printer switches filament at the wrong time during a print"
https://github.com/prusa3d/Slic3r/issues/607
There was a single layer between the raft top and the object first layer
missing on the wipe tower, and after this missing layer all the tool
changes were shifted by one layer, meaning two color print had the colors
switched.
bundled with Slic3r installation, and install it into user's Slic3r profile.
These bundled config bundles will be contained in the Slic3r source
tree under Slic3r/resources/profiles.
Breaking change! The Slic3r user directory has been renamed to Slic3rPE
for the Prusa Edition. Also it is likely, that the Slic3rPE directory
will be reorganized before the final 1.38 release to reserve space
for temporary profiles downloaded from the Internet.
The PlaceholderParser is currently used by the GCode.cpp
and by Printer.cpp to generate a new name for the exported G-code or SVG file.
The PlaceholderParser::process() will throw a runtime_error with
a comprehensive error message.
The G-code export will include these error messages into the G-code text
with !!!!!! separators, and the GUI will inform the user, that the G-code
export failed.
both single_extruder_multi_material and wipe_tower are enabled,
and the print prints with a single extruder only.
Newly the same situation will be handled through a conditional G-code
in the following format:
{if not has_wipe_tower}
; Do the priming
{endif}
fixed crashes when loading a config.ini with "compatible_printers"
disabled export of "compatible_printers" into gcode and config.ini
Enabled compatibility of printing multiple objects with support / no support
with a wipe tower.
gap created between the support and the support sheath.
Now the support sheath will overlap with the support base by 10%
of the extrusion width by default.
G-codes in case of single extruder multiple material setup:
At the start of the print, the filament_gcode_start is executed
for the active extruder only, and the filament_gcode_start /
filament_gcode_end are then executed at each tool change.
When the Prusa MM wipe tower is active, the tool changes are handled
a bit differently: M900 K0 is emited before the wipe tower extrusions start,
and the filament_gcode_start code is executed after the wipe tower extrusions
are done. This rule effectively disables the linear advance over the wipe tower.

Improved handling of custom G-code blocks: Slic3r will try to extract
the target extruder and bed temperatures from the custom G-code blocks.
Removed Perl Flow::new_from_spacing bindings.
Some Fill C++11 beautification.
Fix of a support_material_1st_layer_flow, brim_flow and skirt_flow logic to use the extrusion_width if both first_layer_extrusion_width and support_material_extrusion_width are undefined.
Documented the extrusion width logic in the config tooltips, including the default values.
The values of StaticPrintConfig derived objects were searched by a name
walking through a huge chained if.
Now they are being mapped with a std::map.
Also initialization of StaticPrintConfig classes from their ConfigOptionDef
defaults is done by maintaining a single global definition of each
StaticPrintConfig derived class, and a new instance is initialized
from this static copy.
Also the ConfigOption instances are casted using static_cast
wherever possible, and their types are verified by a virtual type() method.
This approach avoids insiginificant performance penalty of a dynamic_cast.
Also the compare and clone methods were added to ConfigOption,
and the cloning & compare work on binary values, not by serialization.
discover_horizontal_shells() fron Perl to C++, where
the already calculated bridge direction was being lost.
Improved constness of the debug methods

The XS module has to be linked without perl.lib and with
the following parameters to produce a bundle: -bundle -undefined dynamic_lookup
merged "Use submenus for listing options in dropdown menu." #3905
thanks @alexrj
Adapted the "Use submenus" code to sort the menus in the same order
as they appear in the parameter tabs.
Removed the Perl dependencies on Encode, Encode::Locale and Unicode::Normalize.
Added dependency on boost::locale.
Added encode_path, decode_path, normalize_utf8 functions to Slic3r.xs
Slic3r.xs has been made mostly utf8 safe by using the boost::nowide library,
thanks to @alexrj for the idea.
Simplified the encode_path / decode_path stuff:
wxWidgets are unicode already, so there is no need to decode_path() from it.
Perl / win32 interfacing is non-unicode, so decode_path() is executed
on ARGV just at the beginning of the perl scripts.
variable. When set to zero, the usual automatic bridge detection applies.
The bridging angle override may be set at the Infill->Advanced settings,
or through a modifier mesh.

Change of the PlaceholderParser:
All vector configuration values stored into the PlaceholderParser
are expected to be addressed by the extruder ID, therefore
if a vector configuration value is addressed without an index,
a current extruder ID is used.
Also a small fix of fan handling: The fan speed is set to zero
at the start of the G-code if the cooling for the initial extruder
is disabled.
Added UNUSED macro to libslic3r.h, used it to reduce some compile warnings.
Split the Int128 class from Clipper library to a separate file,
extended Int128 with intrinsic types wherever possible for performance,
added new geometric predicates.
Added a draft of new FillRectilinear3, which should reduce overfill near the perimeters in the future.
1x nozzle_dmr for support and top infill,
and 1.125x nozzle_dmr for the rest.
This corresponds roughly to the default values tuned for the Prusa MK2
for normal prints.
Added an "overlap" member variable to fill classes in the preparation
for futher move of the "infill / perimeter" overlap to the Fill class.
Moved the orientation predicates from Fill to Geometry.

The constraint for the "Wipe Tower" checkbox has been raised, so
one will get this error message only if the printer settings has more
than one extruder configured, as the wipe tower does not get generated
for a single extruder print.
due to avoiding the 128bit multiply operations:
A filtered predicate is tried to calculate SlopesEqual()
to minimize the invocation of 128bit multiply operations.

This is a regression of the cooling buffer changes done for multi-material
(supporting different cooling settings for different filaments)
don't apply this extruder to supports. This did not make sense
as the new "don't change tool (0)" extruder choice fits well for non-soluble
and the soluble supports should not be overriden as well.
perimeters if not necessary, don't take the bridging time into account
when slowing down the print.
Removed Extruder & GCodeWriter Perl bindings.
Improved Extruder for constness.
Refactored GCode::m_elapsed_time to struct ElapsedTime.
values to GCode generator, one per active extruder:
bed_temperature
bridge_fan_speed
cooling
disable_fan_first_layers
fan_always_on
fan_below_layer_time
first_layer_bed_temperature
max_fan_speed
min_fan_speed
min_print_speed
slowdown_below_layer_time
Now it remains to extend Slic3r to correctly apply these values.
