Renamer

Demo
You configure how each file needs to be renamed with Python code.
In rename.py, edit the one-line function rename_filename() to define your rename.
This allows you to rename without limitations, as Python code can be as simple or advanced as you want!

Usage

• Edit the rename.py file to define how files need to be named
• Run the renamer.py script by double clicking it
• Select a folder in which to rename the files in

You will need to have the latest Python version installed.

Undoing renaming

• Double click the undo_rename.py script
• Select the folder in which to undo renaming in

Advanced options

Call from terminal

You can also run the scripts from the terminal, offering more options.
See the available command line options:

python rename.py -h

Installing additional features

The script comes with optional pip packages to improve functionality:

• iterate files as shown in file explorer
• allow picking multiple folders with system picker

Open terminal in the cloned folder and create a virtual Python environment called venv to prevent package issues:

python -m venv venv

Activate the created virtual environment:

venv\Scripts\activate

Install required Linux packages, pyqt may also be needed:

yay -S gobject-introspection 

Install the required Python packages:

pip install -r requirements.txt

On Windows, you might need to install some C++ redistributable (see error you will get)

Debugging / testing

Run the script with the verbose option -v and testing option -t for example.
See all options with -v.

How does undoing renaming work?

How it works: After renaming the files, a .rename_history_TIMESTAMP.txt file is saved in the folder.
This can be used to undo the renaming by running the undo_rename.py script:

python undo_rename.py

This launches the folder picker again, where you choose a folder in which the renaming needs to be undone. In the selected folder, it seeks the last created .rename_history_TIMESTAMP.txt file, undoes the renaming according to this file, and deletes it.
