I don't understand what happens to the output. On windows, I
can keep
entering lines but no output gets displayed. Also, can someone
explain a
bit more about lockingTextWriter?
Thanks!
1) The example has a typo; there should be a '.' between the
byLine call
and the array call.
void main() {
stdin.byLine(KeepTerminator.yes) // 1
.map!(a => a.idup) // 2 '.' was missing start
of this line
.array // 3
.sort // 4
.copy( // 5
stdout.lockingTextWriter()); // 6
}
2) The example collects all input before writing anything (so
that it can
sort). Hit your end-of-file character (Ctrl-D) for me to end
the input.
Or direct a file into the process' stdin (not sure how to do
this on
Windows, it's been so long).
On Windows you send EOF by using the Ctrl-Z key sequence.
