What happened to this? Any possibility to make FPC compile to javascript+html5?
I don't know anything about Smart Pascal, but FPC trunk does have the fppas2js converter that's in active development. You could take a look at that.
I'm not sure where something like this would be useful in Web development, quite honestly. The idea of "recompiling" a desktop app into JS and putting it up on the Web doesn't really make sense, from the UI perspective and everything else.
Maybe it would be useful if you needed to write quite a lot of JS and so you did it in Pascal instead.
Almost all modern Web apps integrate with existing Javascript libraries. I don't really see how the Pascal code would work with these. Seems like you would need a Pascal "interface" to the JS libraries.
