[Vala] deleting folders

2012-09-21 Thread D.H. Bahr 
Hello everyone!

GLib.File provides a 'delete' method to delete files and empty folders.

I need to delete a non empty folder so I thought of a recursive method
like this:

bool remove_directory (string path) {
  bool flag = false;
  var directory = File.new_for_path (path);
  
  var enumerator = directory.enumerate_children (
FileAttribute.STANDARD_NAME, 0
  );
  
  FileInfo file_info;
  while ((file_info = enumerator.next_file ()) != null) {
if ((file_info.get_file_type ()) == FileType.DIRECTORY) {
  /*
What should I do here? 
How can I get a File from a FileInfo so I can use the 
'delete' method on it?
  */
}
  }
  return flag;
}


Best regards,

D.H. Bahr

You obviously can't, but you can do the following:

string file_name = file_info.get_name ();
var file = directory.get_child (file_name);

And after that, you can call file.delete().

Regards,
Victor.

Re: [Vala] deleting folders

2012-09-21 Thread Victor Eduardo 
My last message was incomplete. I meant that you can't get a GLib.File directly 
from a GLib.FileInfo object, but you can do it using the way I suggested.

Hope this helps.

Hi,

Victor has already given you the answer - you have to use the parent
directory's get_child method.

If you want, you can consult my Emperor file manager's deletion code
at
https://github.com/tjol/emperor/blob/master/src/modules/basic_actions/basic_actions.vala#L256

As this is a GUI file manager, the code is more complex - it uses
asynchronous methods, asks the user for confirmation, and does error
handling. The core loop, equivalent to what you've been writing, is
here:
https://github.com/tjol/emperor/blob/master/src/modules/basic_actions/basic_actions.vala#L348
