I have written a simple D script that helps me rename files in a dataset to the following format: prefix_id.extension.
I am using foreach loop and std.file.rename for this purpose. After a few tests I have discovered that it deletes files. For example, 186 => 177 => 91 => etc...
I traced the problem down to foreach loop, but I still can't figure out what is wrong. Is it a side effect of foreach loop?
How can I fix this?
Here is the code:
foreach(i, file; list[0..n]) {
// retrieve extension, oldName, newName
immutable extension = (file.canFind(".") ? ("." ~ file.split(".")[$-1]) : "");
immutable oldName = dir.buildPath(file);
immutable newName = dir.buildPath(prefix ~ i.to!string ~ extension);
writeln("extension: ", extension);
writeln("oldName: ", oldName);
writeln("newName: ", newName);
oldName.rename(newName);
}
Any help is greatly appreciated.
Thanks in advance.
