Ropipe

Convert Roman numbers to integers and vice-versa in pipes.

What is ropipe?

Ropipe converts base-10 integers to Roman numbers and vice versa, reading from stdin and printing to stdout. It is designed to be used primarily in pipes. By default, it converts integers to Roman numbers.

Options

• -r: Roman to integer conversion. Integer to Roman is the default behavior.
• -h: Display help message and exit.
• -s: Fail silently, with no output on invalid input.
• -q: Accept quirky Roman numerals like IIII for IV.
• -k: Don't quit on invalid input; continue processing subsequent inputs.

You can use the options concatenated, like -rsk or individually, like -r -s -k.
