Not working with latest 'regex' release

[gazpachoking]

Seems there is an issue when the lastest release of the 'regex' module is installed. There is a ticket on that repo about the change as well. It would also be nice if there was a way to disable the use of that module other than setting the env variable.

Here's a traceback of what's happening:

Yea, this is a problem inherited from rebulk which uses regex as a drop-in replacement for the built in re package if it is installed. Although not a requirement for guessit, regex is installed by many popular packages, e.g. black. As a result, due to a recent API change in regex, guessit's use of rebulk will break if regex is installed.

Heres is another exception report:

Ideal upstream fixes would be for rebulk to offer another option than an environment variable to disable using the regex package or to use the ignore_unused kwarg when calling re.compile.

As a quick fix you can add from os import environ; environ["REGEX_DISABLED"] = "1" before importing guessit. For example, as done here.

I'd prefer the ultimate answer to not be an environment variable. Having to set that from the importing package before the import happens isn't a very nice interface. (But at the moment, we are also setting that env variable.)

[JohnVillalovos]

So what is the environment variable for those of us who would like to work around this issue?

Never mind, I see:

REGEX_DISABLED=1

Fixed with rebulk 2.0.1, just released.
