Hi! This is the staged-recipes linter and your PR looks excellent! 🚀 |

mg5amcnlo looks up all the tools it knows about and can use for code generation using MG5_aMC/input/mg5_configuration.txt. The author assumed you would always compile everything from scratch on every machine you ever used it on. To avoid this and get the correct paths for the conda-forge packages installed as run requirements, use REPLACE_WITH_ variables in mg5_configuration.txt to overwrite with the value of their $PREFIX paths so they will be found correctly at install time.
Instead of trying to properly sed -i edit each line of mg5_configuration.txt during the build, include mg5_configuration.txt as a file in the feedstock source to then overwrite and mv into what is packaged.

At the moment this could technically be noarch, but as the goal is to add compiled components to support Pythia8 in the future, it would have to move away from noarch, so might as well start off as non-noarch.

* Add MadGraph5_aMC@NLO v3.5.7. - c.f. https://github.com/mg5amcnlo/mg5amcnlo - Add tutorial example (tutorial.mg5) for a simple test. * Integration with Pythia8 via MG5aMC_PY8_interface is not yet supported. - c.f. https://github.com/mg5amcnlo/MG5aMC_PY8_interface * Detection of existing libraries (ninja, collier) for NLO calculations is not supported yet either given bugs.

@conda-forge/staged-recipes, ready for review! This is partly a python package, but it is a bit of an odd collection. cc @chrisburr given the particle physics context here. |

.tar.gzfrom the official source or the archive).MadGraph5_aMC@NLOvendors multiple pieces of software, written by the same author. (c.f. Requirements for packaging on conda-forge mg5amcnlo/mg5amcnlo#156). To combat this, as much as possible has been added to conda-forge as packages (c.f. Package mg5amcnlo dependencies hep-packaging-coordination/packaging-hep-simulation-stack#3) though the last bits that exist under the$PREFIX/MG5_aMC/vendorare currently not used and the goal is to eventually work to get these properly moved out. The code under$PREFIX/MG5_aMC/vendoris not accessed until NLO calculations are performed at which time is it compiled. So it is possible to usemg5amcnlowithout triggering this ever (though this limits you to leading order).url) rather than a repo (e.g.git_url) is used in your recipe (see here for more details).
