Re: [Haskell-cafe] ghci & ghc -> JS (Emscripten)

Thank you for all the replies. Luite Stegeman - I was thinking that the LLVM IR code is optimized already or you can run LLVM IR optimization passes to get rid of such things. I think compiling with ghc -fllvm generates LLVM bitcode and then you can simply run emscripten on it to get Javascript - and it should work as expected. We are creating an online graphics (HTML5 canvas, webgl) processing tool - we want to use Haskell as our processing language and we want allow users to interactively process graphics in a functional, lazy manner. We want GHCI to be run inside browser, to allow for smooth work. So what about compiling GHC to JS - please look at: http://repl.it/languages There are a lot of interpreters (like python or ruby) compiled to javascript using emscripten. Would it be possible to compile the GHCI (written in haskell?) with GHC -fllvm to IR bitcode and then to javascript to get the online GHCI interpreter? (not such "online" tools like "Try Haskell", which under the hood compute everything on server) 2013/6/28 Tikhon Jelvis

My understanding is that Try Haskell actually runs the submitted code on a server with mueval rather than compiling it to JavaScript and running it in the client. This is different from some of the other "try" websites (like try.ocamlpro.com), so it's easy to get confused.

Does anybody tried, or is there anywhere a project, of online ghc or ghci (compiled to JavaScript with Emscripten)?

There is Try Haskell![0], source code can be found on GitHub[1]
