Usage
>>> from rene.exact import (Contour,
... Empty,
... Point,
... Polygon)
>>> square = Polygon(Contour([Point(0, 0), Point(4, 0), Point(4, 4),
... Point(0, 4)]),
... [])
>>> square == square
True
>>> square & square == square
True
>>> square | square == square
True
>>> square - square == Empty()
True
>>> square ^ square == Empty()
True
>>> len(square.border.vertices) == 4
True
>>> len(square.holes) == 0
True
>>> from rene.exact import ConstrainedDelaunayTriangulation
>>> (ConstrainedDelaunayTriangulation.from_polygon(square).triangles
... == [Contour([Point(0, 0), Point(4, 0), Point(0, 4)]),
... Contour([Point(0, 4), Point(4, 0), Point(4, 4)])])
True
>>> from rene import Location
>>> from rene.exact import Trapezoidation
>>> trapezoidation = Trapezoidation.from_polygon(square)
>>> all(vertex in trapezoidation for vertex in square.border.vertices)
True
>>> all(trapezoidation.locate(vertex) is Location.BOUNDARY
... for vertex in square.border.vertices)
True

Development
Bumping version
Preparation
Install
bump2version.
Pre-release
Choose which version number category to bump following semver
specification.
Test bumping version
bump2version --dry-run --verbose $CATEGORY

where $CATEGORY is the target version number category name, possible
values are patch/minor/major.
Bump version
bump2version --verbose $CATEGORY

This will set version to major.minor.patch-alpha.
Release
Test bumping version
bump2version --dry-run --verbose release

Bump version
bump2version --verbose release

This will set version to major.minor.patch.
Running tests
Install dependencies
python -m pip install -r requirements-tests.txt
