If you're processing a list of upper-cased names and want to turn them into "properly" cased names, why not just do that?

See also Falsehoods Programmers Believe About Names.

It simply does not work correctly:

#30 There exists an algorithm which transforms names and can be reversed losslessly.

X:\>perl 'JAMES SMITH-JONES' -> 'James Smith-Jones''BOB SMITH-SMYTHE-SMITH' -> +'Bob Smith -Smythe-Smith''J. JONAH JAMESON' -> 'J. Jonah Jameson''BILLY BOB THORN +TON' -> 'B illy Bob Thornton''LUDWIG VAN BEETHOVEN' -> 'Ludwig Van Beethoven' X:\>type my @names = ( 'JAMES SMITH-JONES', 'BOB SMITH-SMYTHE-SMITH', 'J. JONAH JAMESON', 'BILLY BOB THORNTON', 'LUDWIG VAN BEETHOVEN', ); ;; for my $name (@names) { printf qq{'$name' -> }; $name =~ s{ \b ([[:upper:]]+) \b }{\u\L$1}xmsg; print qq{'$name'}; } X:\>

Ol' Ludwig needs a lower case 'v' in his name. Quoting Wikipedia:

The prefix van to the surname "Beethoven" reflects the Flemish origins of the family; the surname suggests that "at some stage they lived at or near a beet-farm".


Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)

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.
