( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I'm not entirely clear on what you want to accomplish, but maybe what you meant was that you want the token type of each token to trigger certain processing? For example, if you have a name "foo" and your parser says it is a variable declaration token, you want to be able to trigger certain processing rules depending on whether that declaration is for an integer, email address, day of week, or some other special type?

If you need to trigger special processing based solely on the combination of a name and a type, you could use a slightly modified version of cdarke 's solution:

use strict; use warnings; package Cow; { sub speak { print ${$_[0]}, " says Moo\n" } } package Horse; { sub speak { print ${$_[0]}, " says 'Hi, my name is Ed'\n" } } package Sheep; { sub speak { print ${$_[0]}, " says Baaaah\n" } } # mapping names to types my %Pasture = ( Bessie => 'Cow', , Annie => 'Cow', , Joe => 'Horse' , Lily => 'Sheep' , James => 'Sheep' ); while (my ($name, $animal) = each(%Pasture)) { # assign a class to each name based on type my $oAnimal = bless(\do{my $anon=$name;}, $animal); # do processing that involves both name and type $oAnimal->speak(); }

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.
