I like to use the Ternaries as suggested in the book "Perl Best Practices".
use strict; use warnings; sub print_response; my $response_code = 200; my $response_content = "All's well!"; use constant OK => 0; use constant BAD_INPUT => 1; use constant SERVICE_ACCESS_ERROR => 31; use constant SERVICE_EXECUTION_ERROR => 32; use constant SERVICE_ERROR => 30; use constant UNDEFINED => 255; $_ = $response_code; my $return_status = /200/ ? OK : /400/ ? BAD_INPUT : /403/ ? SERVICE_ACCESS_ERROR : /500/ ? SERVICE_EXECUTION_ERROR : /503/ ? SERVICE_ERROR : UNDEFINED ; print_response $response_content if $return_status == OK; exit $return_status;

The constants may be overkill, but if the names are important enough to include as comments, why not make them part of the actual perl code?

UPDATE -- Corrected sense of if statement

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.
