Support for extends?

[vanthome]

Hi,
I'm currently comparing some JSON Schema validators and would like to know whether you support the extends attribute for schema "inheritance"
Thanks

extends probably doesn't do what you think it does. It's actually implemented wrong in the library right now. According to the specification, extends takes an array of additional schemas to validate against. In v4, it was renamed to allOf, so if you'd like this functionality, use that instead, which is implemented correctly. Using extends should be considered deprecated.

Is this what you were looking for?

Hi, I look for a functionality which allows me to inherit certain common attributes from something like a base schema to multiple other schemas -- think inheritance.
I just researched a bit and I think you're completely right... in v4 terms what I'm seeking for is "allOf."
Is this already supported by this lib?

[awwright]

Yes, this is in the current master branch, as is anyOf and oneOf. We still need some documentation to describe that fact, which will come along with more v4 features sometime soon.

Maybe join forces with this effort I've found yesterday:
https://github.com/geraintluff/tv4
?

[awwright]

To accomplish what? If you're looking for other specific functionality, then you should probably open a new issue. And if you've found the functionality you were originally looking for, you should probably close this one.

This was just a hint that there are other efforts to implement a v4 compatible validator.
I close this.
Many thanks!
