I'm getting back to Perl after about a decade, so I am, at times, running into cluelessness issues. One I just had is some confusion with split.
I have to process surnames, some of which contain hyphens or whitespace.
If the name contains neither whitespace nor a hyphen, I want to change it to proper case (ucfirst(lc($_)), but if it's hyphenated or has embedded whitespace, I want to split it at either the hyphen or the whitespace, upcase each chunk, and rejoin it.
The way (doubtless close to pessimal) that I'm using right now is something like this:
my $name = $record[0]; # it's being pulled from a roster written (for
+some completely inane reason) in ALL CAPS)
if($name =~ /-| /) {
my @temp = split(/(-| )/,$name) {
ucfirst(lc($_)) foreach(@temp);
$name='';
$name =. $_ foreach(@temp);
}
else {
$name = ucfirst(lc($name));
}
I was expecting a name (say SMITH-JONES) to be divided into three pieces:
"SMITH", "-", "JONES".
This is not what happened: I got
"S","","M","","I","","T","","H","-","J","","O","","N","","E","","S"
What did I do wrong? The split's documentation
seems to say that / / doesn't split between every character, but " " does.

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).
