comment on

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

I didn't say "is wrong", I said "looks wrong" (yes, I know you didn't say I said that either, but you seem to have reacted as though I did). It looks wrong to the extent that it should either be rewritten to "look right" or be commented. However the only appropriate comment effectively says "I did a dumb thing that needs an even dumber comment so that you know I'm being silly". Much better to rewrite it as:

$x = $y; if ($x) { ... }

which makes it quite clear that the assignment is intended and also quite clear what is being tested. Most countries don't tax code by the line so the cost of being clear is pretty low. ;)

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.
