Test code:

require('gaze')('/tmp', function (error) {
  if (error) {
    console.error(error);
    return;
  }

  this.watched(function (error, files) {
    if (error) {
      console.log(error);
      return;
    }
    console.log('watched:', files);
  });

  this.on('added', function (file) {
    console.log('added', file);
  });
  this.on('changed', function (file) {
    console.log('changed', file);
  });
  this.on('deleted', function (file) {
    console.log('deleted', file);
  });
  this.on('renamed', function (file) {
    console.log('renamed', file);
  });
});

1. With this setup, no file creation, deletion, renaming or change in the /tmp directory is picked up.
2. I suspect it's because I need to use the '/tmp/*' pattern to indicate I want to watch files inside.
   But now, if file change and deletion is correctly detected, addition and renaming still does not work.
3. Maybe it is because the parent directory should also be watched to detect new files so I set ['/tmp', '/tmp/*'] as the pattern. But I still get the same behavior 😢
4. I have seen in other issues that you suggest to use the cwd options so now I use '*' for the pattern and '/tmp' as cwd. Now we're getting somwhere! The creation, change and deletion work but still no luck for renaming, I only get a delete event :/
   Another problem is that when I delete all files (rm -f *) only the deletion of the first one is picked up.

What am I doing wrong?

gaze works on file patterns rather than file paths, so you're correct about using the cwd option if you're targeting files in a different cwd than process.cwd().

You should get a rename event.

• Which version of node and OS are you on?
• Are you doing gaze('*', { cwd: '/tmp' }, function() { /* ... */ })?

I have to use cwd because absolute path patterns are not supported?

I am on Debian Jessie and I use Node v0.10.32.

And yep I am doing gaze('*', { cwd: '/tmp' }, …).

And after some time, I get the following error:
