Path patterns support
The syntax for path patterns as described in this proposal (with this fix) is supported. This extension allows one to express RPQs and CFPQs (regular and context-free path queries) in Cypher.
- Syntax description.
- Discussion of the proposal in the openCypher community.
The previous request which contains some discussion, was closed during branches renaming.
Sorry for the delay on this one. I've been busy and not paying a lot of attention to these projects. I'll try to look at it again soon!
After a sabbatical from coding, I'm getting back into things by looking over some outstanding code. This is one of those.
I've done some updates to get this code (mostly) working, as well as proposing some changes to the AST structure, which are in a commit here: https://github.com/cleishm/libcypher-parser/commit/9c35a7e28e2bf2cb2912062cb64e6e98502f8acf. The branch https://github.com/cleishm/libcypher-parser/tree/path-patterns-support is this PR merged onto the current main branch.
If you're still interested in the PR, I'd be happy to discuss the proposed AST format and give thoughts and some effort toward implementing.
Hello, Chris.
Thank you very much for your feedback! We are looking forward to working with you on this extension and would be happy to hear your thoughts on it.
