Build, test, and debug regular expressions
Matches an 8-line block of newline-separated numeric data: a single digit, a decimal number (digits and dots, likely an amount), several lines of comma/space-separated numbers, a comma-separated numeric line, and a trailing line that may contain negative values. Anchored with $ in multiline mode and applied globally, it parses structured financial exports—likely bank or transaction records (the title 'moitepari' is Bulgarian for 'my money')—capturing each field for further processing.
