Thus the first_layer_height is no more object specific. That makes
a lot of sense due to the brim calculation being performed over
all layers at once and due to future merging of supports of
different objects at first layer.
2) Because now first_layer_height is print specific, the relative
first layer height derived from the object layer height was partially
disabled: First the relative first layer height is converted to
an absolute value when importing config, second the side text
was changed from "mm or %" to "mm". Still the UI allows entering %.
Both changes may be controversial, let's wait for user feedback.
".gcode", ".gco", ".g" and ".ngc" were considered to be G-code file
extensions by the G-code import / export file dialogs, but not by
various other functions. Now the G-code extension is tested by
a single function is_gcode_file(string).
1) All slicer's exceptions are now derived from Slic3r::Exception.
2) New exceptions are defined for slicing errors.
3) Exceptions are propagated to the Plater to show.
It remains to modify the slicing back-end to throw the new SlicingError
exceptions instead of std::runtime_error and to show the other exceptions
by a message dialog instead of a notification.
wrappers around boost::format using C++17 variadic templates,
replacing the ugly and verbose
(boost::format("template") % arg1 % arg2).str()
syntax.
The wrappers also implictely convert input parameters including the template
from wxString to UTF8.
The new format wrapper has been applied at multiple places as a start,
also some double macros _(L()) with new single macro _L().
or option values that our poor software does not understand.
This applies to configs added by some forks of slic3r, for example
slic3r++
PrusaSlicer has encountered an error: Failed loading the preset file: #3909
by the PlaceholderParser.
Namely, all the options with the "ratio_over" reference are now handled
correctly by the PlaceholderParser with the exception
of the "first_layer_extrusion_width", which overrides speed of extrusions
by their respective extrusion type.
Also the various extrusion widths (extrusion_width, first_layer_extrusion_width,
external_perimeter_extrusion_width etc.) produce the same numbers
as if ran through the back-end, with the assumption of not overriding
layer height by the variable layer height editing tool or layer height
modifiers.
Extended ConfigBase with set() functions similar to the upstream Slic3r.
ConfigBase::set_deserialize() newly throws if the operation fails.
Extrusion width parameters are newly tested for negative values.
Reworked the FFF testing framework & ConfigBase::set_deserialize()
for more compact tests: set_deserialize() now accepts list
of key / value pairs.
Fixed an incorrect assert in LayerRegion.
DynamicPrintConfig::full_print_config()
new cheaper constructors of DynamicConfig / DynamicPrintConfig from ConfigBase
Unit tests: ported test_model from upstream Slic3r, thanks @lordofhyphens
Unit tests refactored to use less autos and initializer lists for readibility,
DynamicPrintConfig is handled by value, not by shared pointer.
Integration of the "cereal" serialization library.
Serialization / deserialization of the DynamicConfig / DynamicPrintConfig.
DynamicPrintConfig serializes ordinal identifiers instead
of the option key strings to conserve space.
Reworked command line processing for the GUI slic3r. Now the config is loaded first, then the model files (also the configs from AMF/3MF are applied), and lastly the free standing parameters are applied.
Fixed unescaping for command line parameters. The string parameters are now not unescaped, string vector parameters are unescaped only if enquoted.
Tab::load_current_preset() - disabled CallAfter for predictability. With CallAfter, it was difficult to call the method in sequence with other methods.
Fixed some missing ->Destroy() calls on dialogs created from MainFrame
Fixed some compiler warnings.
Added synchronization of GCodePreviewData between the front end / back end
(GCodePreview data is only used if PrintStep psGCodeExport is finished).
Added reset of GCodePreviewData on Print::apply() to conserve RAM.
