How to get a directed hypergraph

[whyydsforever]

It is a really great project!
However, I met some issues in the process. Is this package able to deal with a directed hypergraph or not? Because in the hypergraph, I still want to remain the directed graph structure.

I have the same question

Please add support for directed hypergraph asap (see #31). Thanks.

Confirming the current status: directed hypergraph is not yet implemented.

• dhg/structure/hypergraphs/directed_hypergraph.py is an empty file (0 bytes)
• BaseHypergraph declares abstract methods like _add_hyperedge and _merge_hyperedges that support v2e/e2v direction parameters, but no concrete DiHypergraph class exists
• dhg/__init__.py does not export a DiHypergraph

For now, if you need directed high-order relationships, a workaround is to use DiGraph with clique expansion from a hypergraph via Graph.from_hypergraph_clique, though this loses the hyperedge structure. The directed hypergraph implementation would be a significant feature addition.
