@agbuckley, as discussed in issue #4, it would be interesting for some projects to have access to the more basic features of LHAPDF (set management, maybe parsing
.info file to know what's in there) in a pure-python package (for instance, if I don't need the interpolation features) which can be uploaded to pypi so no gcc management needed, system agnostic, etc.
I put a (at the moment separated) small module in a
At the moment it doesn't have all the features from the
lhapdf script but only exactly the features I needed at this particular point. Once it is fully compatible with the
lhapdf python script I guess it would make sense for the script and this package to become one and the same.
Here's a readme file with the currently supported features: https://gitlab.com/scarlehoff/lhapdf/-/blob/master/python_management/readme.md
I've also added a pyPI file so it can be easily used
pip install lhapdf-management
It installs a script
lhapdf_management which basically does the same as the
lhapdf at Leading Order (and even Next to Leading order). There are a few features from the
lhpadf script that I haven't implemented or I have done it a bit differently but it seems to do most of the stuff (that I often do).
Some technical notes and caveats:
- The module is not doing anything magical, most of it is basically what was inside the
lhapdfscript with changes whenever the
lhapdfinterface was imported
- I removed some/most python2 hiccups (now that debian stable is python3 I feel no need to keep old compatibility, I understand if this is a requirement though)
- I don't currently have access to any cern cluster and I realise that's an important use case (and there are some parts of the script probably dedicated to dealing with it). I'll try to keep it working "by eye" but obviously can't truly test it.
- It is currently separated from the installation of lhapdf but it should be easily done if necessary if people actually like it
