Boy its really hard to navigate this forum for an old thread.
Seems like a lot has changed in D since this thread. Here is the
correct snippet if someone comes searching for "error: undefined
identifier splitter" like me :) (using DMD64 D Compiler v2.058)
import std.stdio, std.string, std.algorithm;
void main() {
ulong[string] dictionary;
foreach(line; stdin.byLine()) {
foreach(word; splitter(strip(line))) {
if(word in dictionary) continue;
auto newID = dictionary.length;
dictionary[word.idup] = newID;
writeln(newID, '\t', word);
}
}
}

This is a bug in the C runtime that D uses, where pipes are not
used correctly. I'm working on getting Walter to fix it as
it's needed for the new std.process as well.
Try:
wordcount2.exe< wordcount2.d
Bye,

Shouldn't the original way work too?
Yes, but the main difference is, bearophile's method simply
opens a file, which FILE * obviously supports no problem. Your
method creates a process with a pipe as the input.
