Install the latest pip & setuptools packages versions

python -m pip install --upgrade pip setuptools

Download and install the latest stable version from PyPI repository

python -m pip install --upgrade bentley_ottmann

Download the latest version from GitHub repository

git clone https://github.com/lycantropos/bentley_ottmann.git
cd bentley_ottmann

Install dependencies

python -m pip install -r requirements.txt

Install

python setup.py install

With segments

>>> from ground.base import get_context
>>> context = get_context()
>>> Point, Segment = context.point_cls, context.segment_cls
>>> unit_segments = [Segment(Point(0, 0), Point(1, 0)), 
...                  Segment(Point(0, 0), Point(0, 1))]

we can check if they intersect

>>> from bentley_ottmann.planar import segments_intersect
>>> segments_intersect(unit_segments)
True

With contours

>>> Contour = context.contour_cls
>>> triangle = Contour([Point(0, 0), Point(1, 0), Point(0, 1)])
>>> degenerate_triangle = Contour([Point(0, 0), Point(2, 0), Point(1, 0)])

we can check if they are self-intersecting or not

>>> from bentley_ottmann.planar import contour_self_intersects
>>> contour_self_intersects(triangle)
False
>>> contour_self_intersects(degenerate_triangle)
True

Install bump2version.

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
