AnyType | Templates , and ready-to-use go lang source files

You need to specify text() to replace the inner text of a node. You also need to reference the anyType node, which you have not.

By the looks of things, none of the relevant nodes actually use the namespaces, so we don't need them at all.

In the NSWag settings, operationGenerationMode is set to MultipleClientsFromOperationId :

From the first operation tag and operation ID (operation name = operation ID, client name = first operation tag).

But the OpenAPI contract (swagger.json file in your case) don't specify operation's id.

I see two solution, choose a other value to operationGenerationMode or specify operation's id.

The other operationGenerationMode values are :

If you were using pure "shapes" without class information, each shape would typically have a common member, e.g., kind and you would use that as an identifier.

From to this thread on GitHub:

The downgrade of the typing module helped me (from the python repository) to version 3.5.2.2. You can also forcefully ignore the typing module in the overloading module by assigning typing = None after the 30th line in the file overloading.py, but I think the typing module features will not be available.

UPDATE: As pointed out by Martijn Pieters ♦ and MisterMiyagi in the comments, it would be much more practical to uninstall the overloading package, rather then degrading your python version, as the standard library already includes functools.singledispatch() to cover this functionality.

Your code with the cast is correct and neccessary.

I am not really sure what you are trying to achieve since you don't utilize the prop inside the styled-component styles, but usually I write something like this:

Remove the ANY lexer rule from your ID rule, it makes no sense to let input like ^ become an ID.

And creating strings is usually done in the lexer. Something like this should do it:

Because the type identifier exists on a different level than the other properties a wrapper class TypeSyntax needed. There are several open feature requests to add wrapping functionality to Jackson e.g. https://github.com/FasterXML/jackson-databind/issues/512

Fortunately polymorphism is supported in Jackson with @JsonTypeInfo and @JsonSubTypes annotations.

Wrapper class should look like:
