not an issue but a question: whats the quality of this library? about jackson-jq HOT 5 CLOSED

Thank you for your comment!

jackson-jq aims to be a compatible jq-1.5 (or the future version of jq once it's released) implementation.

However, as jackson-jq being a java library, some features may differ when/if implemented in the future: Streaming, I/O, and Modules.

• For Streaming and I/O feature, I'm not sure if these can be added to jackson-jq. Actually, I have never tried the features on jq myself yet.
• For Modules, I've been thinking to make it more like a java integration feature which enables importing static methods directly from java classes or something like that.

Other than those, any incompatible behaviors in core language features and built-in functions are considered defects and should be fixed. The biggest issue I'm aware of currently is the lack of Complex Assignment support.

That said, the development will probably be slow. I will continue to work on this, but I haven't been able to spare much time recently.

BTW, I will be releasing jackson-jq v0.0.7 in a few days, which comes with some jq-1.5 features, such as destructuring, regular expressions (with Oniguruma), and so on.

FWIW, I did an experimental Java integration this week that enables me to call static Java methods. Basically, it's a Function implementation which wraps a java.lang.reflect.Method and then takes care of the type conversions. It's experimental, so it only handles some of the types, but the basic approach works. I wrote it in Scala, though.

Yes, I think. I also use jackson-jq for transforming responses from APIs before mapping to Java objects, eliminating the intermediate Java objects.

You should try jackson-jq tool and see if the exact jq code you want to use work or not.

Also, the list of features not yet implemented in jackson-jq might be of help.

Does this answer your question?

Wanted to say firstly thanks a lot for this excellent implementation of jq!

Secondly, I had a similar question - I see you've implemented this from scratch, starting with a javacc parser definition, and implementing nearly everything. An absolutely epic amount of work!

So I wondered if/how you planned to maintain feature parity?

I'm closing this for now. Feel free to reopen if you have further questions.
