My joke generator got a complaint about getting lost in all the map transforms, so in an effort to make my code easier to follow (ahem) I have limited myself to only four occurrances of map in this little project, instead using the trinary operator, a lot of conditionals and comparisons, and far too many variables for such a short program. Enjoy :-)

Oh, you can take out the sleep 1 for hyper speed, if desired, which is useful if you want to use the command-line argument to specify large numbers of fighters. 500 ninjas take too long to duke it out with the sleep statement in.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
