how to filter out source files without declarations during emission?

[boan-anbo]

Hello, my use case is to generate file by namespace.

I createSourceFile in each namespaceContext call, but that means generating files for all namespaces, empty or not.

I only want to write non-empty source files.

I could access the asset emitter after the emission but only to get information about source files and their declarations in globalscope, I don't know what I can do to filter these out before calling writeOutput().

Or perhaps I was not following the correct control flow in creating source file in the first place?

Other than the empty files for empty namespaces, the generated files are OK.

Thank you.

I asume you are talking about the emitter framework, if you registered your declarations on the right scope you should be able to get all declarations added to a file and decide if you want to emit it or not.

typespec/packages/json-schema/src/json-schema-emitter.ts

Line 720 in ff1725c

content.$defs[sf.globalScope.declarations[0].name] = this.#finalizeSourceFileContent(sf);

Side note: emitter framework in its current state as a lot of issues and is not ideal, we are working on a completely different approach to help emitter authors

Got it. Thanks so much and look forward to the alternative approach!
