The only problem with hashes (and hashes of hashes) is that they are seen as "advanced" and noone talks about them until way to late, when the programmer already needs to use... composite data structures. In Perl you (as usual) have to make these for yourself using hashes.

I remember learning Perl. Until someone mentioned hashes when I asked for data structures, I thought that there was no such thing in Perl! The next, mountain like, hurdle was the syntax for dereferencing complex data structures (and subs returning e.g. hashrefs).

Explain these concepts by example and you don't have a problem.

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 or How to display code and escape characters are good places to start.
