Add --ignore-gooey option to README

Hi!

Not a bug so much as an oversight in the readme perhaps?

I spent quite a long time agonising about how to make a CLI interface and a GUI option play nicely together. I knew there had to be an elegant solution somewhere (such as switching between framework/non-framework python.

I noticed in the STDOUT while the program ran however, that it spits out a verbose version of the full call to python which highlighted the --ignore-gooey option which suffices for this perfectly - but there is no mention of this in the README, or any docs I could find.

Could I suggest/request this be highlighted somewhere (and perhaps a more full guide with it if there are other things to consider when using --ignore-gooey that I’m not aware of).

Otherwise, love the package!

I also have this, so if you run my app with no parameters you get the GUI, but if you run in with any parameters you can the CLI version; so this is backwards compatible with the tool before gooey

    if len(sys.argv)>=2:
        if not '--ignore-gooey' in sys.argv:
            sys.argv.append('--ignore-gooey')

This is exactly what I needed (only start Gooey if the script is started without argument, otherwise operate as CLI). It is very simple and straightforward, however there is a caveat that took me some time to understand:

⚠️ you need to place the code before the @Gooey() decorator.

So for example, you can do like this:

import sys
from gooey import Gooey, GooeyParser
# other imports...

# this needs to be *before* the @Gooey decorator!
# (this code allows to only use Gooey when no arguments are passed to the script)
if len(sys.argv) >= 2:
    if not '--ignore-gooey' in sys.argv:
        sys.argv.append('--ignore-gooey')

@Gooey(options=...)
def main():
    parser = ....
    # rest of your code


if __name__ == '__main__':
    main()

Initially I tried putting it in the if __name__ == '__main__' section, but that won’t work.

if __name__ == '__main__':
    # this does NOT work, it is executed too late
    if len(sys.argv) >= 2:
        if not '--ignore-gooey' in sys.argv:
            sys.argv.append('--ignore-gooey')
    main()

1. In Windows I was able to use sys.stdout.isatty().

import sys
def prompt_for_one_of(prompt_text, *args):
    if sys.stdout.isatty():
        while True:
            print(prompt_text)
            for i,s in enumerate(args): print(f'{i+1}. {s}')
            i=input()
            try:
                return args[int(i)-1]
            except:
                pass
        
    else:
        import PySimpleGUI as sg 
        window=sg.Window(Path(__file__).stem,
                         [ [sg.Text(prompt_text)],
                           [sg.Button(t) for t in args] ])
        event, values = window.Read()
        window.Close()
        return event

response=prompt_for_one_of('Would you like to save?', 'Yes', 'No')
