Generic type OpenAPI generation seems not supported

[satoufuyuki]

To Reproduce
Steps to reproduce the behavior:

1. Make a struct that has generic type like this:

type BareSuccessResponse[Res any] struct {
	StatusCode int    `json:"statusCode"`
	Result     Res    `json:"result"`
	Message    string `json:"message"`
}

2. Use the struct as return type like BareSuccessResponse[ExpectedResultStruct]
3. Open swagger

Expected behavior
It should generate the proper extended types for the response

Screenshots

Framework version (please check if it happens with the last
Fuego version before posting): 0.17.0

Go version (please check if it happens with the last Go version before posting): 1.23.4

Additional context
My current workaround is explicitly specify the response type using OptionAddResponse. But that actually removes the BareSuccessResponse structure.

Well spotted! It's probably related to the Kin dependency, I'll have a look this week.

For information, this doesn't impact running code, just OpenAPI description.

@rizerkrof identified it as a regression, it was available on previous versions. It'll be fixed for the next release :)

Yes, regression was introduced by this commit.

Oops my bad, I'll fix and add a test for generics args to make sure it won't happen again

I've identified the bug. It seems unrelated to 72a07362.

It seems that the generic names are not supported by OpenAPI specification:

schema \"BareSuccessResponse[github.com/go-fuego/fuego/examples/petstore/models.Pets]\": identifier \"BareSuccessResponse[github.com/go-fuego/fuego/examples/petstore/models.Pets]\" is not supported by OpenAPIv3 standard (charset: [\"a-zA-Z0-9._-\"])"

@ccoVeille @dylanhitt I'll add a function to replace invalid characters and strip module name except last path, are you ok with this?

BareSuccessResponse[github.com/go-fuego/fuego/examples/petstore/models.Pets] -> BareSuccessResponse_models.Pets

Here's a proof that a simple renaming works

It'll be available in the next release. In the meantime, you can work with the @main version of Fuego instead of the @latest.
