There is a proposal for openCypher to introduce syntax for path constraints specification: - [Root](https://github.com/opencypher/openCypher/pull/187) - Context-free constraints in the original [CIP](https://github.com/thobe/openCypher/blob/rpq/cip/1.accepted/CIP2017-02-06-Path-Patterns.adoc#153-compared-to-context-free-languages) We are working on context-free path querying for RedisGraph which uses Cypher via [libsypher](https://github.com/cleishm/libcypher-parser/tree/23755428c5d6a70a83f55f34a2afae4180179fbc). It is necessary - [x] to extend libcypher to be able to use context-free (CF) constraints in Cypher - [x] to extend RedisGraph translator to support CF constraints - [x] introduce grammar normalization - [x] integrate with our CFPQ agorithm
