Your replies make it seem like you think others owe you something. As you're aware, nobody here is trying to "sell" you the project in an attempt to get you interested. I don't know why when someone shares a project they find interesting, people come out waving their little OS flags "but it doesn't run on my Amiga".
"patches welcome" imply "implement it yourself" as does a simple "not supported" or "wont fix".
Following the "patches welcome" logic to the extreme, you would never need anymore than a touring complete language, because you could implement everything yourself.
Of course you don't need to implement as much with free software as with closed one and that is great, but you need to invest time before you can use it and it is valid to criticize that fact.
Ok, thats an option. But I am not sure it its worth the effort.
Normally if I discover some interesting project, that I want to try out, I just check it out in /tmp, run it and then decide if I want to continue using it and install it or just remove it.
Setting up a ~20GB VM takes time and diskspace.
Also I looked at the source for a bit and from what I see it only needs the winapi to set the title of a console window, so in theory it should be platform independent if that is removed. Not sure it is, because it does a lot of other stuff.
Just as I said, nice project, but I am afraid its not for me in its current state.
