Want to separate a string by spaces, but not escaped spaces

Question

I would like to write some D code that would take a string, and split it by " ", but not "\ ". I normally use std.array.split for splitting, but it obviously can't handle this. What would be the best way to do what I want?

Answer 1

Regular expressions (+ lookbehind) is powerful enough for that:

import std.regex;
void main()
{
    auto parts = split(r"foo bar\ bar baz", regex(r"(?<!\\) "));
    assert(parts == ["foo", r"bar\ bar", "baz"]);
}
