passagemath-macaulay2

=================================================================================================== passagemath: Computing in commutative algebra, algebraic geometry and related fields with Macaulay2

passagemath <https://github.com/passagemath/passagemath>__ is open source mathematical software in Python, released under the GNU General Public Licence GPLv2+.

It is a fork of SageMath <https://www.sagemath.org/>__, which has been developed 2005-2025 under the motto “Creating a Viable Open Source Alternative to Magma, Maple, Mathematica, and MATLAB”.

The passagemath fork uses the motto "Creating a Free Passage Between the Scientific Python Ecosystem and Mathematical Software Communities." It was created in October 2024 with the following goals:

• providing modularized installation with pip,
• establishing first-class membership in the scientific Python ecosystem,
• giving clear attribution of upstream projects <https://groups.google.com/g/sage-devel/c/6HO1HEtL1Fs/m/G002rPGpAAAJ>__,
• providing independently usable Python interfaces to upstream libraries,
• offering platform portability and integration testing services <https://github.com/passagemath/passagemath/issues/704>__ to upstream projects,
• inviting collaborations with upstream projects,
• building a professional, respectful, inclusive community <https://groups.google.com/g/sage-devel/c/xBzaINHWwUQ>__,
• [empowering Sage users to participate in the scientific Python ecosystem <https://github.com/passagemath/passagemath/issues/248](https://github.com/passagemath/passagemath/issues/248)https://github.com/passagemath/passagemath/issues/248>__ by publishing packages,
• developing a port to Pyodide <https://pyodide.org/en/stable/>__ for serverless deployment with Javascript,
• developing a native Windows port.

Full documentation <https://doc.sagemath.org/html/en/index.html>__ is available online.

passagemath attempts to support and provides binary wheels suitable for all major Linux distributions and recent versions of macOS.

For the Linux aarch64 (ARM) platform, some third-party packages are still missing wheels; see <https://github.com/passagemath/passagemath?tab=readme-ov-file#full-installation-of-passagemath-from-binary-wheels-on-pypi>__ for instructions for building them from source.

Binary wheels for native Windows (x86_64) are are available for a subset of the passagemath distributions. Use of the full functionality of passagemath on Windows currently requires the use of Windows Subsystem for Linux (WSL) or virtualization.

The supported Python versions in the passagemath 10.6.x series are 3.9.x-3.13.x.

About this pip-installable distribution package

This pip-installable distribution passagemath-macaulay2 provides an interface to Macaulay2 <https://github.com/Macaulay2/M2>_.

What is included

• Python interface to Macaulay 2 <https://doc.sagemath.org/html/en/reference/interfaces/sage/interfaces/macaulay2.html>_

• The binary wheels published on PyPI include a prebuilt copy of Macaulay 2.

Examples

Using Macaulay 2 on the command line::

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-macaulay2" sage -sh -c 'M2'

Finding the installation location of Macaulay 2::

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-macaulay2[test]" ipython

In [1]: from sage.features.macaulay2 import Macaulay2

In [2]: Macaulay2().absolute_filename()
Out[2]: '.../bin/M2'

Using the Python interface::

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-macaulay2[test]" ipython

In [1]: from sage.all__sagemath_macaulay2 import *

In [2]: R = macaulay2('QQ[x, y]'); R
Out[2]: QQ[x..y]

In [3]: S = R / macaulay2('ideal {x^2 - y}'); S
Out[3]:
QQ[x..y]
--------
  2
 x  - y

In [4]: S.gens()
Out[4]: {x, y}
