Hi Jeffrey, at least two of the pages you link to reference the github of the package, which has a very short example. That alone is not very useful, but the magic seems to happen in the runMatchfunction. That function obviously comes from is the package you linked to, so we know where to find the source code. There you can see that runMatch basically just callsrunGraql. (And it also presents the results in a somewhat nicer form than pure json, but that's not relevant.) The runGraql function in turn is just a few lines below in the source code and exposes thatit does nothing more than call the graql.sh shell script. So all the library does is to add a bit of Haskell type checking on top of the Java+JavaScript+Bash proprietary behemoth. That means even if someone has a Haskell program, the core question is how to use the graql.sh script – which is outside the scope of a Haskell mailing list I suppose, but I hope the Grakn project has some documentation about that. The Grakn approach to modeling a knowledge graph looks good, but I'm not even sure if we have something equivalent Haskell-side. We do have the necessary hypergraph libraries and all, and it's a fun area, so we probably do. But I highly doubt whatever we do have supports Graql. After all, why use an extra language if you can use functions directly? Sorry I have to disappoint you there. Cheers, MarLinn On 2017-03-14 04:53, Jeffrey Brown wrote:
Graql[1] is a (and stands for) graph query language. It is unusually expressive, allowing relationships to be members of other relationships[2] -- effectively, allowing one edge to be an endpoint of another edge.
Someone named Felix posted a Haskell library for generating Graql queries[3].
Does anyone have a Haskell program that not only generates but uses such a query?
