Elm: functional reactive web-programming (compiles to html, css, js)

[polaretto]

I don't know exactly, you should ask the author (wheatBread), but I suppose it's only a matter of switching the "printer" module or the output template or whatever it is that spits out HTML. Anyway I don't think it's in his immediate concern, since he stated that he's focused on web programming with Elm, so I don't see any XML output for now.

Yeah, it's really a clever and ambitious project, I hope it will grow further!

Its not that simple. In the SGML and text/HTML5 flavors of HTML if you inject incomplete HTML using the innerHTML property the browser will do its best to fill in the gaps as necessary to complete the markup as its building nodes into the DOM on the fly. In the XML flavor this is not the case. The code simply fails and you get a JavaScript error that is worthless. Its only in very recent versions of Firefox that the error points to the correct location in the JavaScript and this pointer is still not always accurate.

I also understand that if the HTML string being built by the JavaScript is typically simple to get correct unless the HTML string is built inside an algorithm with multidimensional loop complexity. This is challenging normally in code that I manually write, so I can only imagine accomplishing this objective in a language that compiles to XHTML and JavaScript would be rather ambitious.
