Change #{ … } to #\< … \>

def puts(str)  
`document.getElementById("STDOUT")['innerHTML'] = document.getElementById("STDOUT")['innerHTML'] + "#<str>\n"`  
end

And if you move “puts” into module Kernel, then you can also use the “p”  
method, which is equivalent to puts(obj.inspect).

Michael

OK fine, thanks.

first i had a js error at line 609 (unterminated string) of the  
resulting file because i get :

document… = document… + "\_str  
";

instead of having :

document… = document… + \_str + “\n”;

and, after correcting that point i get from js console :

Error: uncaught exception: [object Object]

my html file being at :

index.html\>

Again, vielen dank 😉
