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

Have you ever seen the Runops::Switch module (available from the CPAN).

That module allows you to override the way that perl interprets its opcodes.

I *imagine* that you could combine the techniques used in that module, together with the B::Deparse module in order to do what you want.

From what I remember, all "if" and "unless" statements in perl are internally translated into "AND" (or "OR") statements. So:- if(i > 3) { print "bob" } is internally the same as i > 3 && print "bob". So you probably want to start by looking at overriding the OP_AND opcode....

Title:
Use:  <p> text here (a paragraph) </p>

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.
