Hi, it is well known that Dyalog APL and NGN APL both have an online demo version which is a very nice feature: * for trying some quick idea when not at home; * for letting other people discover GNU APL; * for providing some kind of "permanent link" in forums, etc. (for instance on "golf" challenge forums; * etc.
Both systems are quite different: * Dyalog APL has a server-side software * NGN APL has a client-side javascript software Of course, the server-side software needs some special care: * security issues if the user is allowed to execute some system commands; * CPU/memory/time quotas Wouldn't it be nice to have GNU APL providing its own demo-version? I browsed a little and found about Emscripten: https://github.com/kripken/emscripten/wiki https://github.com/kripken/emscripten/wiki/Tutorial It looks like even some large projects could be "easely" compiledinto javascript. Do you think it would be easy to do it with GNU APL? If someone is able to compile it to javascript, I could perfectly write the HTML/CSS/Javascript web interface as a contribution.
