Missing interface in non-modular code generation

[alfie80]

Hi Team,

I have below model definitions in Typespec and I found the the interfaces CatDef and DefaultPets will be missed in the generated codes. However, switching to modular mode (setting is-modular-library to true), the interfaces are generated.

model DefaultPets {
    catList?: CatDef[] = #[
        #{
            catType: "American Shorthair"
        }
    ];
}

model PetSettings {
    petList?: {
      cat?: DefaultPets.catList;
    },
}

model CatDef {
  catType: string;
}

The problem seems relates to cat?: DefaultPets.catList in model PetSettings. After changing it to below, the interface CatDef can be generated.

model PetSettings {
    petList?: {
      cat?: CatDef[] = #[
        #{
            catType: "American Shorthair"
         }
      ];
    },
}

Here is my emitter setting in tspconfig.yaml:

emit:
  - '@azure-tools/typespec-ts'
options:
  "@azure-tools/typespec-ts":
    azure-sdk-for-js: false
    enable-operation-group: true
    include-shortcuts: true
    is-modular-library: false
    ignore-property-name-normalize: true

It seems there is bug in RLC for referenced model generation. @alfie80 May I know why we generate RLC libraries(that is is-modular-library: false) in your case? I am asking because RLC is in maintaince mode and any issues reported may be handled as low priority. Could we switch to Modular(that is is-modular-library) then?

Thanks @MaryGao for your reply. Does that mean the RLC will not be supported any more in future? Do you know when? We now generate RLC as our SDK's low level codes. Is the Modular our only choice? Thanks.

Hi @MaryGao, any chance to check my questions above? Is the Modular the only support mode going forward? Or any equivalent RLC mode will be supported? We notice there are significant diffs between these two and we have to carefully consider the migration to Modular if RLC is not supported any more. Appreciate your advice. Thanks!

@alfie80 Sorry for the late response. RLC is in maitinanace model now which menas we will never build any new features and we will only work on fix when necessary. In your case, I think we could directly update the original typespec to not use reference type to workaround. But moving forward Modular would be our supported mode and here is a quick start guide and complete guide.

We would encourage you to switch to Modular which is also bundle size optimization but with more friendly usage. But let us know if any concern!
