Re: Is there a True Boolean type in Perl?
On Mon, Oct 15, 2007 at 01:27:26PM -0700, Michael Barto wrote:
As both Java and Javascript both have a 'true' and 'false' or Boolean
data type, is there any interest in evolution of Perl to have a true
Boolean. Or what is the preferred method to do this in Perl.
The place to discuss this is the perl5-porters mailing list, not an
obscure platform-specific mailing list.
And the answer is no. Because we already have a real Boolean. We have
boolean *context*. An operator like ?: forces its first operand to be
evaluated in boolean context:
$value ? 'true' : 'false'
That first operand can, of course, be a complex expression, the end
result of which is evaluated in boolean context:
cheezburger-{$cutecat}-() ? print LOL! : print OH NOES!
We also don't have int or float or a numeric type (the internals do, but
Perl the language doesn't) - we have numeric context. Consider this:
$ perl -e 'print foo\n if 2abc == 2def'
The == operator forces both its operands to be evaulated in numeric
context before comparing them. As numbers, 2abc and 2def are both just
plain ol' 2, so the == returns true and we print. If we change it to
this:
$ perl -e 'print foo\n if 2abc eq 2def'
then the eq operator evaluates its operands in string context, where
2abc and 2def most definitely aren't the same.
The C programmers want me to use 0's and 1's.
Seems reasonable. Those do evaluate to false and true in perl. Perl's
comparison operators return 1 for true and the empty string for false.
In numeric context that's the same as returning 1 and 0 because:
'' == 0

if instead you're doing something like ...

If he says he wants ISO 8859 1 and he says he wants the Euro sign, then
he wants ISO 8859 15 which is identical to 8859 1 but with the generic

I am using MacOS X (10.1.5), and Perl, v.5.6.0. An excerpt from one of the author's programs shows the following three lines: open MAIL, |mail YOUR_ADDRESS_HERE; print MAIL bad news: $someone guessed $someguess\n; close MAIL; ($someone and $someguess have been assigned appropriate values prior to the above three lines.) I suspect the above works fine in a typical UNIX environment, e.g., open MAIL, |mail [EMAIL PROTECTED]; print MAIL bad news: $someone guessed $someguess\n; close MAIL; How can I get the above to work on my Macintosh? (I don't get an error message, nor do I receive an email.) Any help would be greatly appreciated. To send mail, you need two components. A mail client (aka a mail user agent or MUA) and an SMTP program (aka a mail transport agent or MTA). The 'mail' program is an MUA. It passes messages to a local MTA for delivery. IIRC on OS X the MTA (sendmail) is installed, but not configured, so 'mail' successfully hands the message over to sendmail, which then neither knows what to do with it, nor knows how to warn you of the fact. -- David Cantrell Beekeeping is like being a lion tamer, but with smaller lions, and more of them. -- arp
