Optional path needs to be supported

In Hyak when a part of the path is set to be optional, if the optional argument in the path is not provided, it would not include the optional path. This is not supported with AutoRest, which is needed by Key Vault service.

For example for /subscriptions/{subscriptionId}/[resourceGroups/{resourceGroupName}]/resources if {resourceGroupName} is provided, the base URL should be /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/resources and when {resourceGroupName} is not provided, the base URL should be /subscriptions/{subscriptionId}/resources

Optional path parameters are supported in URI Templates (RFC 6570) , but they don’t work the way the original example suggested.
Consider this template:

 /subscriptions/{subscriptionId}/resourceGroups{/resourceGroupName}/resources 

Note the / is inside the curly braces. When {resourceGroupName} is not provided, the URL would be,

/subscriptions/{subscriptionId}/resourceGroups/resources 

I realize that doesn’t help much, but if OpenAPI are going to support optional parameters then it is likely going to be the 6570 way. I doubt we could reach consensus on the idea that the parent path segment is “attached” to the parameter segment.

Howdy!

In our planning for driving towards a stable ‘1.0’ release, I’m marking this issue as ‘deferred’ 💤 and we’re going to review it during the post-1.0 planning cycle.

It’s not to say that we’re not going to work on it, or that this isn’t not important, but at the moment, we’re picking and choosing the stuff we must do before 1.0. 🏇 🏇 🏇

We’ll make sure we pick this back up at that point. 🎉
