About this pip-installable distribution package

This pip-installable source distribution passagemath-palp provides an interface to the Package for Analyzing Lattice Polytopes <http://hep.itp.tuwien.ac.at/~kreuzer/CY/CYpalp.html> (PALP) by M. Kreuzer and H. Skarke, a set of C programs for calculations with lattice polytopes and applications to toric geometry.

What is included

• The binary wheels published on PyPI include a prebuilt copy of PALP.

Examples

Using PALP programs on the command line:

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-palp" sage -sh -c 'echo "14 2 3 4 5" | class.x -f -po zbin'
0kR-0 0MB 0kIP 0kNF-0k 5_13 v8r8 f10r10 10b6 0s 0u 0n
14 2 3 4 5 R=152 +0sl hit=0 IP=276 NF=179 (0)
Writing zbin: 152+0sl 0m+0s 644b  u36 done: 0s

Finding the installation location of a PALP program:

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-palp[test]" ipython

In [1]: from sage.features.palp import PalpExecutable

In [2]: PalpExecutable("poly", 5).absolute_filename()

Use with sage.geometry:

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-palp[test]" ipython
