( #3333=superdoc: print w/replies, xml ) Need Help??
Thanks for help ;-)

I've actually made it work by taking a slightly different approach. The rewrote the to_case() sub to return a reference to appropriate case subroutine (lc(), or uc() ...)
use strict; sub to_case { my ($char) = @_; if ($char eq "\U$char") { return sub {uc(shift)}; } else { return sub {lc(shift)}; } } print to_case("FOO")->("bAr") ."\n"; print to_case("foo")->("BaR") ."\n";
Here's the output produced by the script:
BAR bar
Sometimes, asking questions helps to come come up with an answer (eventually ;-). I'd appreciate it if you could show me another approach to solving my 'problem'. I'm not sure if returning sub references is a good thing?

Of course, I realize that my 'solution' presented here is way worse than what you've suggested since I might as well just pass that string which I want to modify (it's case) to the sub and simply return it's modified version in the end. However, in my script I might need to format a number of separate strings to matching case, and most of those strings may not be 'known' at the time i first invoke the to_case() sub (say, i may call it once and store sub reference for later use...).

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 How to display code and escape characters are good places to start.
