Can ghcjs compile itself? #693

Open louisabraham opened 6 years ago

louisabraham commented 6 years ago

I would like to make a haskell interpreter in javascript. Has anyone attempted to compile ghcjs to js?

My experience with ghcjs suggests to me that this would be extremely challenging at this time.

Luite has done it for one of his talks, but I'm not sure whether it still works or whether the performance is acceptable for real-world use.

I think that was compiling Fay, so still Haskell->JS in the browser. Would be super cool to see GHCJS self host!

@louisabraham something like code.world might be useful to look at; you can write a subset of Haskell therein.

cdsmith commented 5 years ago

@chessai @louisabraham You can write anything that GHCJS accepts at http://code.world/haskell, except for (a) no TemplateHaskell, and (b) available libraries include many widely used libraries, but not everything, and (c) projects must fit in one module (but @nomeata built https://github.com/nomeata/hs-all-in-one to consolidate multi-module projects into one module, if you are really desperate!).

It's worth noting that CodeWorld doesn't compile GHCJS for the browser, though; instead, it compiles on a server that I operate.
