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

A note on usage. The tr/// operator does not have [...] character classes like regexes (as might be used in s///), but only ranges, e.g., a-z, so the \[ [ ] sequences in the tr/\[A-Z]/[a-z]/ expression in the OP represent literal [ ] characters (see tr/// in Quote-Like Operators in perlop).

So '[' is being translated to '[' and ']' to ']'. This does no harm (indeed, the tr/// compiler may optimize this away), but suggests a misunderstanding of tr///.

And since the tr/// is just translating upper case to lower, a simple
    $_ = lc;
statement might be clearer, hence better (see lc).

Update: I see now that Marshall has already made this point at the end of this post.


Give a man a fish:  <%-{-{-{-<

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.
