Hi, I'm following through TDPL and am trying to import a txt

Currently I have

foreach (line; stdin.byLine()) {

}

and would like it to analyse the supplied text file. Is this 
possible in the way that I'm thinking, or is there another way?

Thanks

#!/usr/bin/rdmd <file.txt

That's limitation of the shebang line. Most implementation's only 
accept one argument.

However, you can simply do:

./foo.d < foo.text

or:

void main() {
   auto f = File(args[1]);
}


or rdmd --loop for tiny scripts:

 echo "abc" | rdmd --loop='line.splitter("").writeln
