Error running yfc #37

After "npm install -g yang-forge" as root, and running yfc, I get this error -

Thanks for flagging this issue. We're currently planning an update to yang-forge to leverage latest development in yang-js and yang-express modules and will have a newer build published shortly. I'll update this ticket once new package ready for testing.

Thanks! On Fri, Aug 5, 2016 at 7:09 AM ramukima notifications@github.com wrote:

Got same error with existing yang-forge code. Is there any update on when the new code will be available? Thanks

sekur commented 8 years ago

I expect to publish an update in about a week. It'd be helpful to know what features from YF you're interested in that is not provided by yang-js/yang-express so I can prioritize those capabilities in the upcoming update.

jfulreader commented 8 years ago

Thanks for the quick reply. Initially I am mainly looking for functionality that would allow me to plugin different data providers underneath the northbound APIs. Later am looking to use the Yang model registry and composition capabilities.

Got it. In that case, I think you'd find an upcoming "yang-store" module more interesting. I haven't published it yet but the idea is to define ORM style data backend providers using YANG modules. What types of data providers did you have in mind?

jfulreader commented 8 years ago

Mine would be REST or NETCONF to agents running on other hosts.

Exactly what I am looking for as well, and for that, the store API must go beyond connect/import. If the store APIs align to -

  1. set/get for leaf
  2. iterator, get-next, set for list

or alike, things would perfectly fit for someone to be able to implement their own store provider implementation for a given YANG module. Further better will be to allow hooking up store at individual datastructure levels e.g. container/list/leaf etc. Imagine a Person object where the name/age comes from one datastore while the address/phone number comes from another datastore.

Not sure if this is what you planned for 'Store' module, looking at current code, it does not appear to be. May be you can describe your plan for Store module in more details, and that will help correct few of my assumptions.

sekur commented 8 years ago

@jfulreader - in that case, yang-express should be sufficient I think.

@ramukima - that's an interesting approach. I wasn't planning on many-to-one (multi source to a model) but rather one-to-many (a model to multi source) type implementation. Also many-to-many as in different models coming from different sources (but not at the level of schema tree elements as you describe). I've just split off yang-store as a separate module and going through the appropriate "rpc" operations that should be expressed. It'd be great to get further input on it.
