Hey Roboticus,
Talking about translationThanks for your reply and I perfectly know what you are talking about. Little details can produce an unsupportable overhead. I spend much time meditating over JS and there are indeed many problems not easily solved. BUT I learned not only a lot about JS but also about Perl. Saying so I have my personal toy project patching B::Deparse to generate JS and eLisp from a limited Perl dialect. Avoiding the mental overhead to always switch between different keywords and syntax already pays off for me. (like sub {} <-> function () {...} for lambdas or my <-> var for lexicals.). This is far away from a full automated translation of the whole language but good enough for me, since I am aware of the different scoping rules of lexicals and I can check against possible conflicts. =)
But the intention of my question was differentWhen digging into Ruby I'm always surprised to be surrounded by Perl idioms hiding behind a pretty syntax, to an extent that Ruby feels like a Perl-dialect + a prebuild object system. (It's somehow fascinating and disturbing hearing people praising Ruby-idioms taken from Perl and simultaneously bashing the source of that features.) This has lead me to the question if anyone ever tried to use sourcefilters to completely tokenize and translate a different language ( not necessarily more than 90% compatible to an existing one) and then to evaluate the generated Perl-code.
Cheers Rolf ( addicted to the Perl Programming Language) In reply to Re^2: sourcefilter with complete parser?
