dts2as pretty much does the same job as externc, except it uses TypeScript definitions instead of JS externs. So yes, it probably could replace externc.
One thing to keep in mind is that dts2as requires Node.js. Everything in the SDK currently uses Java, as far as I know. Requiring another runtime will make it more challenging to build everything. - Josh On Sun, Mar 13, 2016 at 2:47 PM, Michael Schmalle <teotigraphix...@gmail.com > wrote: > Curious Josh if your typescript definition compiler can replace externc? > How much overlap is there? > > I wanted to do exactly what you did with typescipt and use it's compiler > but I didn't have enough time so I went the gcc extern route, there was a > couple massive discussions a year ago bout that and using typescript > definition files. > > Mike > > On Sun, Mar 13, 2016 at 4:08 PM, Christofer Dutz < > christofer.d...@c-ware.de> > wrote: > > > Thanks for the explanation :-) > > > > And what's actually happening in GCL?
