Why? I mean what’s the reason to use a different regex engine?

Oh it’s not regex at all. I got confused. Sorry!

Yup, it's a DSL for matching against dependency grammar.

While regex matches characters in strings, this matches grammar and other kinds of language data.

Within a directed graph of nodes (words) related by grammatical relations.

That’s sounds pretty cool!

Are there examples of interesting usages?

Not really interesting usages, but there are a few examples in the rich comment block https://github.com/simongray/datalinguist/blob/master/src/dk/simongray/datalinguist/dependency.clj#L351-L376

I am thinking about making another DSL on top of it since I actually kinda dislike using text-based DSLs in Clojure 😆

since it is matching against nodes in a directed graph it should be possible to represent it using Datomic-style triples

I want to use it for building patterns to detect various Chinese sentence patterns

I actually made my own Java API for doing the same stuff years ago, not knowing CoreNLP included such a feature already… https://github.com/simongray/StatementAnnotator/tree/master/src/main/java/statements/patterns
