Enum from YANG-Model #478

Closed temabeloglinski closed 5 months ago

temabeloglinski commented 7 months ago

Hi Olof! I have a question about enumeration from yang-model. Is it possible by any method using Clixon to select data not only about the configured values, but also about all possible values? For example, via restconf.

You can get the YANG schema itself via netconf or restconf.

@olofhagsand I understand correctly that through netconf or restconf you can get a similar structure with all enumeration values?

Yes,in RFC 6022, for example,ietf-netconf-monitoring.yang defines container schemas state and get-schema RPC, to retrieve the YANG definitions. Clixon sypports this by default. See option CLICON_NETCONF_MONITORING. There is also the module-set including a module list in RFC8525 ietf-yang-library.yang that lists the modules. That is about getting the schema.

Regarding enum values, a recent commit improved the enum/value API by two new functions: yang_enum2int()and yang_enum_int_value().

Maybe this is more what you are looking for?
