That will do the filtering correctly - but what I was hoping
was to actually prune at the directory level and not drill down
to the files in of an unwanted directory (e.g. .git). The
problem with this and what I'm trying to overcome is accessing
lots of files and directories recursively all of which I want
to skip. Much like there is a *followSymlink* it would be nice
if a predicate were accepted to *followDirectory* in general or
some way to cause that.
what about the following?
import std.algorithm, std.array, std.regex;
import std.stdio, std.file;
void main()
{
auto exclude = regex(r"\.git", "g");
dirEntries("/path/GIT", SpanMode.breadth)
.filter!(a => match(a.name, exclude).empty)
.writeln();
}
I think if you go breadth first, you can filter out the unwanted
directories before it delves into them
