Although this likely isn't the most efficient way to do this,
it's cropped up and here's what I have so far. The idea is to
drop all the unwanted pathname and only leave the filename (I'm
sure there's a function there already, just not finding it off
hand).
Why is this failing?
[quote]
bool skipOver(alias pred = "a == b", R1, R2)(ref R1 r1, R2 r2);
If startsWith(r1, r2), consume the corresponding elements off
r1 and return true. Otherwise, leave r1 unchanged and return
false.

import std.algorithm;
import std.stdio;
void main() {
string filename = r"something/long\or short";
bool skipped;
do {
skipped = false;
//try to handle either slash in this case.
skipped |= filename.skipOver('\\');
skipped |= filename.skipOver('/');
skipped |= filename.skipOver(r"\");
skipped |= filename.skipOver(r"/");
} while (skipped);
//originally was: do {} while(filename.skipOver('\\'));
//asserts, filename hasn't changed.
assert(filename == "or short", filename);
}
