Out of curiosity, is it possible to output a json AST of a .d.ts file with dukat? https://github.com/Kotlin/dukat

What for do you need it? And which AST do you need?

If you need original d.ts AST you can just use typescript.

I'm creating bindings for clojurescript based on typescript .d.ts files. I've forked dukat and managed to generate a JSON representation of the nodes visited in the translator-string project. I just wanted to know if there was some util that's already there.

hmm, what do you mean by I can use typescript? Is their a tsc flag or something I can use? I've read this: https://github.com/Microsoft/TypeScript/wiki/Using-the-Compiler-API and my main concern is I'm not sure in a .d.ts that I would accurately get what is exported out of it. Since I'm essentially just using dukat to eventually output clojurescript I figured it would be good to leverage since all the hard work of breaking down all the exports is already done.

I'm not sure if I'm using the term AST correctly, mostly I just want to know what classes and objects are exported with their members and arguments.

dukat does add a bunch of imports no matter what which makes the JSON a bit bigger than what I need it for, but here's what leftpad's index.d.ts looks like (actual useful stuff near the bottom)

Something nice about using `dukat`'s representation is it breaks up all the types of args, which in the future might be useful to generate clojurescript spec tests.
