I have a file containing data like,

--- data.txt ---
abc, 1
def, 2
--- end data.txt ---

I try to read in the data like following, but the the codes do 
not compile:

--- mytest.d ---
import std.file, std.stdio;
void main() {
     auto arr = "data.txt".slurp!(string, int)("%s, %s");
     foreach(a; arr) {
         writefln("%s: %d", a[0], a[1]);
     }
}
--- end mytest.d ---

Any idea?

Thanks in advance,
Big Tummy

Use (I also have added a space after the second %s because slurp 
is buggy with Windows-style newlines):

auto arr = slurp!(string, int)("data.txt", "%s, %s ");

Bye,

Sorry, ignore this because it's essentially the same code as 
yours. What's the error you are receiving? (And better to ask 
such questions in D.learn).

Bye,

Not working for me. It seems to have something to do with string

dmd git head compiles your code. Use the cutting edge dmd or please wait
