Writing a function to traverse a "configuration" array I have a series of if/elsifs that switch based on what kind of data it encounters, ie. by whatever ref() returns.

here's an mini-example:

my $ref = ref($_); if( $ref eq 'Regexp' ) { #ah, we are matching a match } elsif( $ref eq 'CODE') { #sombody slipped a sub{} in here, ok } elsif( $ref eq 'ARRAY') { #an @array we have found } elsif( $ref eq 'HASH') { #a %hash, obviously } elsif( $ref eq '') { #must be a $scalar } else { warn "Unknown ref() wth is a $ref ?!"; }

My question for the clergy is: what's a more elegant way to accomplish this? or what is your favorite idiom for this task?

also, have i hit on all the possible values that ref() can return?

  • 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).
