• I refuse to believe this way is the only way to capture every single digit… It’s horrible.

  I know about regex101.com, but it's not helping me in this case. The struggle isn't a logical one, it's a syntactical one. Since I can't find in the documentation said syntax I would assume it does not exist. But I kinda refuse to believe this horrible redundancy can't be shortened without losing the single digit matching. No matter how I turn it either matches the whole thing as one long digit, or the last digit... - Source: Reddit / 24 days ago
