Circle is pretty cool. If I remember correctly, Sean didn't fork clang, but wrote his own C++ front end and then some. So one motivated person can do it, it's not insurmountable.

#22Links to the “whitepaper” just link to the repo. Is this the whitepaper: https://github.com/seanbaxter/circle/tree/master/new_whitepa... ?
There are also 3 walkthroughs that are kind of buried:
1. https://github.com/seanbaxter/circle/blob/master/walkthrough...

#23When coding in C++ I often thought "Why isn't there an imperative programming language in the preprocessor?"
This was the only thing holding me back from finishing my metacircular TODO app.

#24This seems useful for code generation. Cannot relate this to any previous problems I encountered using c++ Any other interesting use of this?
My favorite use is putting user-defined attributes on data members, and using reflection to generate a UI to manipulate those values. I do it with these shadertoys: https://github.com/seanbaxter/shaders#reflection-and-attribu... Just mark your declarations up with custom attributes: [[.imgui::range_float { .1, 5 }]] float Zoom = 1.5; [[.imgui::range_float { 0, 1 }]] float Speed = .15; [[.imgui::range_float { .1, 1 }]…
In c++ there are some hacks that can start to help getting someswhere close (https://ossia.io/posts/reflection/) but this solution with attributes is what everyone dreams of

Seems that it could be used to solve an old-time classic: generate a mapping from an enum value to its string representation. Another use case that comes to my mind is maybe automating test case generation. Occasionally I was running into situations where I thought code generation could be useful, but not sure what could be a "killer app" equivalent for this feature.

Re: Circle: C++ Automation Language
#27It's very neat but closed-source and by the looks of it is likely to stay that way. I can't see it being used in any mission-critical projects unless the source is fully disclosed and viewed/analysed by the community... until then it's a "nifty black box".
