  use-extension:
    "@autorest/modelerfour" : "~4.1.0" 
  

  • each Http operation (via .protocol.http) will now have a separate path and uri properties.
    Both are still templates, and will have parameters.
    The parameters for the uri property will have in set to ParameterLocation.Uri
    The parameters for the path property will continue to have in set to ParameterLocation.Path

  • autorest-core recently added an option to aggressively deduplicate inline models (ie, ones without a name) and modeler-four based generator will have that enabled by default. (ie deduplicate-inline-models: true)
    This may increase deduplication time on extremely large openapi models.

  • this package contains the initial code for the flattener plugin, however it is not yet enabled.

  • updated @azure-tools/codemodel package to 3.0.241:
    uri (required) was added to HttpRequest
flattenedNames (optional) was added to Property (in anticipation of supporting flattening)
