SyntaxWarning: invalid escape sequence

[imTHAI]

Hello,

I just reinstalled my Mac and did a restore:

$ mackup restore
/opt/homebrew/Cellar/mackup/0.8.41/libexec/lib/python3.13/site-packages/docopt.py:165: SyntaxWarning: invalid escape sequence '\S'
  name = re.findall('(<\S*?>)', source)[0]
/opt/homebrew/Cellar/mackup/0.8.41/libexec/lib/python3.13/site-packages/docopt.py:166: SyntaxWarning: invalid escape sequence '\['
  value = re.findall('\[default: (.*)\]', source, flags=re.I)
/opt/homebrew/Cellar/mackup/0.8.41/libexec/lib/python3.13/site-packages/docopt.py:207: SyntaxWarning: invalid escape sequence '\['
  matched = re.findall('\[default: (.*)\]', description, flags=re.I)
/opt/homebrew/Cellar/mackup/0.8.41/libexec/lib/python3.13/site-packages/docopt.py:456: SyntaxWarning: invalid escape sequence '\S'
  split = re.split('\n *(<\S+?>|-\S+?)', doc)[1:]

Do you know what's wrong? It is not the first time I use mackup after I install one of my Mac but it's the first time I get this error.

Same issue here after upgrading via homebrew to version: 0.8.41

Same. Related to https://github.com/lra/mackup/issues/1986. Not sure why that one was closed.

@muzimuzhi posted what seems to so far be a working solution in that closed issue. I'm pasting it below for posterity.

It looks like docopt hasn't been updated in 7 years.
