String interpolation with code containing strings

[Rodrigo de Salvo Braz]

Hi,

I notice that

Nemerle.IO.print("This is string interpolation: $(if (true) "true";
else "false";)");

won't compile. I guess the nested strings confuse the parser. Is this
a bug? In principle it seems that it can be avoided although it may
complicate the parser.

I am asking because I was considering writing a note about it in the
"Grokking" section.

Thanks!

No. This is by design. Use nested string instead:
Nemerle.IO.print(<#This is string interpolation: $(if (true) "true";
else "false";)#>);

The "print" is a macro which take string in parameter. You try pass to
it following literals:
1) "This is string interpolation: $(if (true) "
2) true
3) "; else "
4) false
5) ";)"
