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". ;-)

    ... "properly" ...   Nobody ever mentioned lossless reversal. :)
