pyfeyn2 2.4.2 documentation

PyFeyn2

Forked from https://pyfeyn.hepforge.org/

PyFeyn is a Python-language based system for drawing Feynman diagrams. It was inspired by the C++ FeynDiagram system, and aims to provide the same functionality and quality of output as that, with the added benefits of a modern interpreted language, an improved interface and output direct to both EPS and PDF. Behind the scenes, PyFeyn uses the excellent PyX system - you can use PyX constructs in PyFeyn diagrams if you want, too.

Dependencies

• libmagickwand-dev (to display pdfs in a jupyter-notebook, might require a policy change of the imagemagick config for PDFs, see Troubleshooting)

• ghostscript

• latexmk

• (graphviz)

• (feynmp-auto/feynmf)

Installation

poerty install --with docs --with dev
poetry shell
