Geometer is a geometry library for Python 3 that uses projective geometry and
numpy for fast geometric computation. In projective geometry every point in 2D
is represented by a three-dimensional vector and every point in 3D is
represented by a four-dimensional vector. This has the following advantages:
There are points at infinity that can be treated just like normal points.
- Projective transformations are described by matrices but they can also
represent affine transformations i.e. also translations.
- Every two lines have a unique point of intersection if they lie in the same
plane. Parallel lines have a point of intersection at infinity.
- Points of intersection, planes or lines through given points can be calculated
using simple cross products or tensor diagrams.
- Special complex points at infinity and cross ratios can be used to calculate
angles and to construct perpendicular geometric structures.
- Most of the computation in the library done via tensor diagrams (using
numpy.einsum).
NOTE: If this package has multiple flavors (see below), then use one of them instead of the name specified above. NOTE: This is a Python port. Instead of py311-geometer listed in the above command, you can pick from the names under the Packages section.
all: remove explicit versions in USES=python for "3.x+"
The logic in USES=python will automatically convert this to 3.8+ by
itself.
Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

- Remove upper bound of py-numpy for now
- Bump PORTREVISION for package change
We should remove all PYNUMPY and use the real version requirement.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
(Only the first 15 lines of the commit message are shown above )
Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.
