Do you all know of a good place I can study or learn about these short/compact functions? Is it called perl golf? What is perl golf?

Re^3: Golf code in perl (Context)

And no, please don't use "golfed" code for any other purpose than to play golf. It's simply unmaintainable in that form, write-only code in its purest form. Prefer writing longer, readable code that you (or any other maintainer) will still understand in half a year, a year, or five years. If you resort to "dirty tricks" (like string xor plus counting NUL bytes), add a comment that explains how the trick works and the requirements for that trick (e.g. strings must only contain ACGT, all upper case, both the same length, etc). Don't make your future self invent a time machine to come back and severely hurt you for the mess you will have written.

Title:
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.
