copyPath function
Copies all of the files in the from
directory to to
.
This is similar to cp -R <from> <to>
:
- Symlinks are supported.
- Existing files are over-written, if any.
- If
to
is withinfrom
, throws ArgumentError (an infinite operation). - If
from
andto
are canonically the same, no operation occurs.
Returns a future that completes when complete.
Implementation
Future<void> copyPath(String from, String to) async {
if (_doNothing(from, to)) {
return;
}
await Directory(to).create(recursive: true);
await for (final file in Directory(from).list(recursive: true)) {
final copyTo = p.join(to, p.relative(file.path, from: from));
if (file is Directory) {
await Directory(copyTo).create(recursive: true);
} else if (file is File) {
await File(file.path).copy(copyTo);
} else if (file is Link) {
await Link(copyTo).create(await file.target(), recursive: true);
}
}
}
