Function casts hid casting between potentially incompatible type
signatures (using int instead of Py_ssize_t). As it happens this seems
not to have caused any bugs on supported platforms so this change is
mainly for correctness and to avoid problems in the future.
Use struct identifiers in comments before the value.
This has some advantages:
- The struct identifiers didn't mix well with other code-comments,
where other comments were wrapped onto the next line.
- Minor changes could re-align all other comments in the struct.
- PyVarObject_HEAD_INIT & tp_name are no longer placed on the same line.
Remove overly verbose comments copied from PyTypeObject (Python v2.x),
these aren't especially helpful and get outdated.
Also corrected some outdated names:
- PyTypeObject.tp_print -> tp_vectorcall_offset
- PyTypeObject.tp_reserved -> tp_as_async
Recent refactoring to use uint relied on indirect includes and precompiled
headers for uint to be defined. Explicitly include BLI_sys_types where this
type is used now.
This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.
Regex find and replace: `UNUSED\((\w+)\)` -> `/*$1*/`
Use a shorter/simpler license convention, stops the header taking so
much space.

The header files in freestyle utilize the using-directive at the global
file scope. This is a bad practice as it pollutes the global name space
causing possible ambiguous reference compilation errors. In particular,
the DNA files that are included by freestyle will cause those ambiguous
reference errors when the developers adds a DNA member with a type name
that also exist in the Freestyle name space, such as Curve and possibly
others.
This patch does the minimal work needed to resolve that by moving the
using-directives from the headers into the corresponding translation
units.

While `tp_print` was deprecated, Python 3.8+ uses this for
'tp_vectorcall_offset' which wasn't stated in the comment from
efd71aad4f.
Instead of suppressing clang-tidy, use preprocessor a check since
this properly represents the difference between Python versions.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

This revision extends the Freestyle Python API to make for style module writing
easier.
- freestyle.types.Stroke: A proper support for reversed() is implemented. It
works the same with other Python sequence objects (returns an iterator starting
from the end). This is in effect equivalent to Stroke.stroke_vertices_end().
- freestyle.types.StrokeVertexIterator: An incremented, decremented and reversed
method are added. The first two methods return a new StrokeVertexIterator
object that has been incremented and decremented, respectively. The reversed
method returns a new StrokeVertexIterator object that will traverse stroke
vertices in the opposite direction.
- freestyle.types.Interface0DIterator: Its constructor now accepts a Stroke
object to create an Interface0DIterator that traverses stroke vertices. This is
in effect equivalent to Stroke.vertices_begin(). The new API makes stroke
shaders involving function calls much simpler as illustrated below:
# in the old API
it = stroke.stroke_vertices_begin()
for vert in it:
result = somefunc(Interface0DIterator(it))
# in the new API
it = Interface0DIterator(stroke)
for vert in it:
result = somefunc(it)

Changes were made in Stroke::Resample(int) in C++ to prevent a potential infinite loop
caused by an inconsistency between Stroke::_Length and the stroke length computed
based on stroke vertices. Such a stroke length inconsistency is usually caused by missing
calls of Stroke::UpdateLength() (i.e., API implementation bugs), but also may occur due
to scripting errors in user-defined style modules. This commit is meant to help script
writters to identify the latter error cases. Now Stroke.resample(int) may raise a runtime
error to signal an error condition.
* Proper handling of keyword arguments was implemented in Operators and ContextFunctions,
as well as in methods of Interface0D, Interface1D, Iterator, their subclasses, Noise and
IntegrationType.
* Operators' methods and functions in the ContextFunctions module were renamed from
CamelCase to lower cases + underscores. Style modules were updated accordingly.
* Additional code clean-up was also made.
Handling of keyword arguments in Python wrapper class constructors was revised.
This revision is mainly focused on Interface0D, Interface1D, Iterator, and
their subclasses, as well as a few additional view map component classes.
Implementation notes: Because of the extensive use of constructor overloading
in the underlying C++ classes, the corresponding Python wrappers try to parse
arguments through multiple calls of PyArg_ParseTupleAndKeywords() if needed.
The downside of this implementation is that most argument errors result in the
same error message ("invalid argument(s)") without indicating what is wrong.
For now this issue is left for future work.
* Now the instantiation of ViewVertex is prohibited since the underlying
C++ class is an abstract class.
* Removed the .cast_to_interface0diterator() method from CurvePointIterator
and StrokeVertexIterator. Instead the constructor of Interface0DIterator now
accepts the instances of these two iterator classes to construct a nested
Interface0DIterator instance that can be passed to Function0D functor objects.
Specifically, an iterator 'it' is passed to a functor 'func' as follows:
func(Interface0DIterator(it))
instead of:
func(it.cast_to_interface0diterator())
* Boolean arguments of class constructors only accept values of boolean type.
Input values of other types are considered as error.
* Additional code clean-up was made.
Major API updates were made to address code review comments.
This revision mostly focuses on Python wrappers of C++ 0D and 1D elements (i.e.,
Interface0D and Interface1D, as well as their subclasses).
* Most getter/setter methods were reimplemented as attributes using PyGetSetDef.
Vector attributes are now implemented based on mathutils callbacks. Boolean
attributes now only accept boolean values.
* The __getitem__ method was removed and the Sequence protocol was used instead.
* The naming of methods and attributes was fixed to follow the naming conventions
of the Blender Python API (i.e., lower case + underscores for methods and attributes,
and CamelCase for classes). Some naming inconsistency within the Freestyle Python
API was also addressed.
* The Freestyle API had a number of method names including prefix/suffix "A" and
"B", and their meanings were inconsistent (i.e., referring to different things
depending on the classes). The names with these two letters were replaced with
more straightforward names. Also some attribute names were changed so as to indicate
the type of the value (e.g., FEdge.next_fedge instead of FEdge.next_edge) in line
with other names explicitly indicating what the value is (e.g., SVertex.viewvertex).
* In addition, some code clean-up was done in both C++ and Python.
Notes:
In summary, the following irregular naming changes were made through this revision
(those resulting from regular changes of naming conventions are not listed):
- CurvePoint: {A,B} --> {first,second}_svertex
- FEdge: vertex{A,B} --> {first,second}_svertex
- FEdge: {next,previous}Edge --> {next,previous}_fedge
- FEdgeSharp: normal{A,B} --> normal_{right,left}
- FEdgeSharp: {a,b}FaceMark --> face_mark_{right,left}
- FEdgeSharp: {a,b}Material --> material_{right,left}
- FEdgeSharp: {a,b}MaterialIndex --> material_index_{right,left}
- FrsCurve: empty --> is_empty
- FrsCurve: nSegments --> segments_size
- TVertex: mate() --> get_mate()
- ViewEdge: fedge{A,B} --> {first,last}_fedge
- ViewEdge: setaShape, aShape --> occlude
- ViewEdge: {A,B} --> {first,last}_viewvertex
- ViewMap: getScene3dBBox --> scene_bbox
* Stroke::Resample(int nPoints) was not properly working when a wrong
value was returned from Stroke::getLength2D(), resulting in repeated
warning messages "Warning: incorrect points number" during stroke
rendering. The main cause was that stroke geometry shaders did not
update the two-dimensional (2D) length (also referred to as curvilinear
abscissa) after they modified the 2D points of stroke vertices. Now
all stroke geometry shaders make explicit calls for Stroke::UpdateLength()
that has been introduced for recomputing the 2D length. Many thanks to
Josef who reported the problem together with sample .blend files for
reproducing the issue.
* Missing Python wrapper of Stroke::getLength2D() was added.
(http://freestyle.sourceforge.net/doc/html/index.html) has been
incorporated into the Blender/Freestyle Python API implementation
in the form of Sphinx-based embedded docstrings. Some C++-specific
descriptions of classes and functions were revised so that they are
suitable for Python programmers. Missing docstrings were filled,
and sparse descriptions were extended. By means of the new
documentation system for Blender, an up-to-date Freestyle Python
API reference will be part of the Blender 2.5 documentation.
