Hi all,
I'm porting some C++ code into D that uses istream to read lines like
label 3
where there can spaces or tabs between the 2 fields. In c++, this is:
string l;
int i;
istr l i;
What's the equivalent in D? It appears that D formatted read for
strings grabs everything up to a newline

You can use the C++ plugin, which provides a debugger. Just make
sure you aren't using optlink, I don't think it generates
