Backup your GitLab repos to GitHub

GitLab recently decided to silently delete any repositories that hadn't been accessed in the last year. The announcement didn't go over well and they soon caved to public pressure and decided to instead back up inactive repos to object storage instead of unilaterally deleting them. I'm glad they reconsidered, but the experience left me with a bad taste in my mouth, so I decided to look into (relatively) low

Best used by copying the downloaded file to your path. If downloading with a browser, right click and use 'Save Link As' and then choose 'keep' from w/in the download's dropdown to avoid security issues.

Example of how to 'install' bat from the CLI (and bypass above browser issues):

"""
A handy and cool recursive lambda (!) to safely get an item out of a deeply
nested list or iterable:

>>> unwrap = lambda x: unwrap(next(iter(x), None)) if '__iter__' in dir(x) and not isinstance(x, str) else x
>>> unwrap(2)
2
>>> unwrap(["hi"])
'hi'
>>> unwrap([[[[[[["ok ok, i get it"]]]]]]])
