I have studied most of the available options for ruby: optimist, optimist_xl, rationalist, slop etc.</p> <p>I have also built several parsers of my own.. using different approaches.</p> <p>Today I started thinking: What is the <em>main</em> problem when parsing arguments.</p> <p>Well, the main problem is to know whether an item is a key or a value.</p> <p>Example:<br> <code>--name Olle --age 32 --verbose my_file.txt</code></p>
