Hi,
I need an Input Range that iterates a file character by
character. In bioinformatics this is often important, and having
a D-range is of course preferable than any foreach-byLine
combination, since we can apply filters and other goodies from
std.algorithm. In this implementation, I am simply filtering out
new-lines, as an example.
import std.stdio;
import std.conv;
import std.algorithm;
void main() {
auto f = File("someFile.txt", "r");
foreach(c; f.byChunk(1).filter!(a => to!char(a[0]) != '\n'))
write(to!char(c[0]));
}
Is this the right way to do it? I was a bit surprised that
std.stdio doesn't provide a "byChar" or "byByte" range. Is there
a reason for this, or is this a too special need?
