Hi there,

Thanks for creating this library.

I'm searching for a Haskell library that will let me play with edge-weighted directed graphs. igraph seems to offer this, but it only supports igraph-0.6, which I can't find.

Are there any plans to add the possibility of weighted edges (and Dijkstra's algorithm) to this library? If not, could you briefly explain what needs to be done, so I can create the PR myself?

Cheers :)

Hello @kaizhang,

I am writing on behalf of the igraph development team. It's great to see this project, and that igraph is being exposed from more programming languages! We were not aware of haskell-igraph before.

igraph development has picked up momentum. We are aiming for a 1.0 release with a stable API, hopefully within the year. This also means that at the moment lots of breaking changes are being made. We just released version 0.9.0 with a new build system and many infrastructural improvements. It is useful for us to be aware of downstream projects, so that their needs can be taken into account when planning for 1.0. Therefore, I would like to invite you to the igraph forum at https://igraph.discourse.group/ and encourage you to give us feedback on the experience of hooking up igraph to Haskell, as well as any issues you might have encountered with version 0.9.

May relate to ghc-8.6:
