( #3333=superdoc: print w/replies, xml ) Need Help??

No, you're right. What's in the top-level curlies ends up being top-level code in the package. My parsers always look like:

use strict; use warnings; my $grammar = <<'__EOI__'; { use strict; use warnings; } ... __EOI__

Note the use of heredocs. Much better than q{} since you don't have to escape some backslashes and some curlies. For example, to have a production match a single backslash,

Single quote heredoc: rule: /\\/
Single quote literal: rule: /\\\/ or rule: /\\\\/

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.
