Feature request: Add prefix/suffix to filename with timestamp and/or unique number before moving to archive folder

[spirkaa]

Add prefix/suffix to filename with human-readable timestamp (datetime.now().strftime("%Y-%m-%d %H:%M:%S")) and/or unique number before moving to archive folder. In my opinion, all files must stay in archive folder without overwriting.

My scanner (HP 426dn) can't generate unique filename with timestamp by himself, and when he scanning to empty folder (/inbox), filename is always myscan0001.pdf, meaning after ocrmypdf-auto proccessing this file and moving it to archive folder, previously scanned file will be overwritten.

This!! in addition to that, it would be great if I could just specify the filename, so my files get names like 2022-11-12_17-22-10.pdf

I kinda made it work by changing the following in ocrmypdf-auto.py:

   def _map_output_path(self, input_path):
        if self.output_mode == AutoOcrScheduler.MIRROR_TREE:
            return self.output_dir / (input_path - self.input_dir)
        else:
            assert self.output_mode == AutoOcrScheduler.SINGLE_FOLDER
#            output_path = self.output_dir / (input_path.name)
            output_path = self.output_dir / '{}{}'.format(datetime.now().strftime('%Y-%m-%d_%H-%M-%S'),input_path.suffix)
            unique = 1
#            if output_path.exists() or output_path in self.current_outputs:
#                suffix = '.{}.{}{}'.format(datetime.now().strftime('%Y%m%d'), unique, output_path.suffix)
#               output_path = output_path.with_suffix(suffix)

            while output_path.exists() or output_path in self.current_outputs:
                unique = unique + 1
                output_path = self.output_dir / '{}_{}{}'.format(datetime.now().strftime('%Y-%m-%d_%H-%M-%S'), unique,input_path.suffix)
#               output_path = output_path.with_suffix('.{}{}'.format(unique, output_path.suffix), depth=2)
            return output_path

I then mapped it to the container (docker compose):

volumes:      
      - "/path/to/modded/file/ocrmypdf-auto_modded.py:/app/ocrmypdf-auto.py"
      - "/etc/localtime:/etc/localtime:ro"
