Thanks for the work. Got a little refactoring to do, mainly in the future I'd recommend using Python's argparse module if you haven't as it's less error-prone than the old getopt.

For example, this code will handle the help message + validate every argument properly and return you a neat dictionary. You don't have to keep the help, argument logic, and testing arguments separate.

def parse_command_line_arguments():
    """
    Parses command line arguments and returns a dictionary containing options and arguments.
    """
    parser = argparse.ArgumentParser(description="This script performs text extraction from the application and move "
                                                 "generated POT files in the translations project in order to compare "
                                                 "with translations source and output a translation completion "
                                                 "indicator for each language.")
    parser.add_argument("translations_path", help="relative or absolute path to GD-Learn-translations directory.")
    parser.add_argument("-t", "--threshold", type=int, help="Minimum completion percentage value for a language to be integrated. "
                                                            "Language integration is skipped if no value is given.")
    parser.add_argument("-E", "--skip-extract", action="store_true", help="Skip the extraction of strings and POT files generation.")
    parser.add_argument("-S", "--skip-sync", action="store_true", help="Skip the synchronization and merge of PO files with the reference POT files.")
    return vars(parser.parse_args())

The dictionary returned by the function looks like this:

{'translations_path': 'test', 'threshold': None, 'skip_extract': False, 'skip_sync': False}

Anyway I'll refactor, test, and this should be good to merge.

Just tackled the first half, I pushed the changes to your branch directly. I had only a good half hour to work on this but will refactor the second half and merge ASAP, hopefully tonight, otherwise, tomorrow.

Note that I'm pushing commits directly to your branch, so you don't have anything to do, as mentioned before this makes the contribution process more efficient for everyone. If you have any questions about the changes don't hesitate to use the Files changed tab to leave comments.

Another note regarding additions to .gitignore: in general if you participate to open source projects maintainers will ask you not to push changes that are specific to your development environment.

Instead of using the shared .gitignore file, you can add exclude patterns to .git/info/exclude, which is always local to your copy of the repository.

Thank you so much for taking the time to work on this! I'll take it for a spin and make a new release by the end of the week :)

I think you said you're French too, right? If you happen to go to Game Camp in June, in Lille, ( https://gamecamp.fr/ ) let me know! My teammate and I will be there

Also good to know. I have to admit I saw both solutions in documentation and choose getopt for its simplicity, but the result with arparse is indeed much cleaner.

You're welcome, I'm glad I helped ! Don't forget there is still this strange behavior regarding the wrapped strings that resulted in unrecognized translations in the end.

The script will do it's job, but we might not be quite at the end of the road yet. Let me know how it went with your tests. Maybe you can open another issue if you spot something ? You can get my screenshot and comments if needed.

I've scrolled into GD-Learning code without much success on spotting where strings are actually used. If you need me to continue I might need a few advices on which scenes or GD scripts to look into.

Yes ! I live in Nantes. I'd love to go and meet you there ! Unfortunately I'm pretty sure I won't make it, I have already several work appointments on those dates.

But don't worry, I'll stick around ! This first contribution was a really good experience to me. Helps me keeping a few fingers in true development work. You're refactor is also very interesting. So I'll see if there is another issue that I can give a hand on. Feel free to send suggestions if you have anything in mind, now or later.
