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

This is one of those cases where for readability sake, I would separate the split logic from the case logic. This isn't going to win any perl golf competitions but future maintainers will not try to hunt you down!

#!/usr/bin/env perl use strict; use warnings; my $input = "I am a GIRL"; my $output = []; # split input by non-words ... if you need to keep non-word # characters then you'll need a different regex foreach my $word ( split( /\W+/, $input ) ) { # if the word is all upper case and it's not a single letter if( $word =~ /^\p{Uppercase}+$/ && length( $word ) > 1 ) { push( @$output, $word ); } else { push( @$output, lc $word ); } } print join( ' ', @$output ), "\n";


update: Fix regex from /\p{Lu}+/ to /^\p{Uppercase}+$/

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.
