ok, I didn't test that first one very well. It worked for directory copies,
but I didn't test non directories. So here is the fixed operation for non
directories, where it just copies the single file.
So it now does two cases:
copy regular_file destinationDirectory
copy folder destinationDirectory
What I'd like to add is wildcard support for something like
copy folder/* destinationDirectory
I suppose also it could be enhanced to handle all the robocopy options, but I'm
just trying out the copy speeds for now.
module main;
import std.stdio;
import std.file;
import std.path;
import std.datetime;
import std.parallelism;
int main(string[] argv)
{
if (argv.length != 3){
writeln ("need to specify src and dest dir");
return 0;
}
// TODO expand this to handle wildcard
string dest = argv[$-1];
foreach(string dir; argv[1..$-1])
{
writeln("copying directory: "~ dir );
auto st1 = Clock.currTime(); //Current time in local time.
cpdir(dir,dest);
auto st2 = Clock.currTime(); //Current time in local time.
auto dif = st2 - st1 ;
auto ts= dif.toString();
writeln("time:"~ts);
}
writeln("finished !");
return 0;
}
void cpdir(in char[] pathname ,in char[] dest){
DirEntry deSrc = dirEntry(pathname);
string[] files;
if (!exists(dest)){
mkdir (dest); // makes dest root
}
DirEntry destDe = dirEntry(dest);
if(!destDe.isDir()){
throw new FileException( destDe.name, " is not a directory");
}
string destName = destDe.name ~ '/';
string destRoot = destName ~ baseName(deSrc.name);
if(!deSrc.isDir()){
copy(deSrc.name,destRoot);
}
else {
string srcRoot = deSrc.name;
int srcLen = srcRoot.length;
mkdir(destRoot);
// make an array of the regular files only, also create the
directory structure
// Since it is SpanMode.breadth, can just use mkdir
foreach(DirEntry e; dirEntries(deSrc.name, SpanMode.breadth,
false)){
if (attrIsDir(e.linkAttributes)){
string destDir = destRoot ~ e.name[srcLen..$];
mkdir(destDir);
}
else{
files ~= e.name;
}
}
// parallel foreach for regular files
foreach(fn ; taskPool.parallel(files)) {
string dfn = destRoot ~ fn[srcLen..$];
copy(fn,dfn);
}
}
}
