Message-Id: <IM9DCx.poM@zorch.sf-bay.org>
I'm pleased to announce the first CPAN release of DBIx-Threaded,
a pure Perl module that provides an apartment
threaded implementation of the DBI, thereby permitting DBI
objects (connection and statement handles) to be passed
between arbitrary perl threads (via Thread::Queue::Duplex objects).
Details available at http://www.presicient.com/dbixthrd,
or (shortly) at CPAN.

I'm working on Linux. I have some Perl programs that launch a program by
just putting the command line in backticks. So if program A launches
program B this way, is there any way for program B to get the PID of
program A?
Thanks!

Linux provide getppid(2) which gets the parent process ID. Perl supports
getppid().

Great! That's exactly what I need! (It also saves the pain of adding
functions to make launching programs add an argument like
"--launchpid=$pid" as well as reading it in the launched program!)
Thanks.

Which will probably return the PID of the shell that the
backticks started rather than the PID of program A.

Subject: How to find all modules, required by a given CPAN module
Message-Id: <431a3ee2$0$161$a3f2974a@nnrp1.numericable.fr>
Hi,
I'd like to install the Pixie module (CPAN)
Is there a fast way of finding recursively all modules needed by Pixie.
Currently my methodology is less than satisfying.
I make and make test the Pixie module.
If it fails I'm looking at the error messages and try to locate and
install the modules mentioned in the error messages.
Then I retry to build / test pixie again.
I'm quite sure, that there is a better way of doing it.
Thanks in advance for any pointers and bye

And you haven't even tried:
perldoc -q module
yet?

The CPAN module will find and install the dependencies for you:
perldoc CPAN

I wrote one

Besides simplifying, it shows work and plots math formulas. It is not
available publicly though. There is a Math::Symbolic module, but I
found it extremely lacking.

Also, it doesn't give the right answer.
"Text form: ((x^2-6x+9)/(x^2-3x-10))/((x^2-5x+6)/(x^2-8x+15)) simplifies to
(x-3)/(x+2)"
No, it doesn't.

I will appreciate corrections and suggestions. What's the right answer
there?

Subject: Variable::Strongly::Typed 1.0.0 released
Message-Id: <IM9DCK.n7A@zorch.sf-bay.org>
DESCRIPTION
This modules allow you to strongly type your variables. Also known
as the 'no fun' module - it can greatly enhance you code's quality
and robustness.
By enforcing types on some (or all) of your variables you will
eliminate
a large class of careless (& not so careless) errors.
This could also aid an editor or code-browsing tools to verify code
correctness without having to execute the script.
SYNOPSIS
use Variable::Strongly::Typed;
my $int :TYPE('int'); # must have an 'int' value
my $float :TYPE('float'); # must have a 'float' value
my $string :TYPE('string'); # must not be a reference
my $file :TYPE('IO::File'); # must be an IO::File
my @array_of_ints :TYPE('int'); # Each slot must contain an
int
my %hash_of_floats :TYPE('float'); # Each value must be a
float
my @array_of_rgb :TYPE(\&red_green_blue); # my enumerated type
# ... and later ...
$int = 23; # All is well
$int = 'howdy!'; # This line will croak with a good error
message
$float = 3.23; # All is well, nothing to see here
$float = new XML::Parser; # croak!
$array_of_ints[23] = 44; # Groovy
$array_of_ints[12] = 'yah '; # croak!
$hash_of_floats{pi} = 3.14159; # no problem
$hash_of_floats{e} = new IO::File; # croak!
# Return 1 if this val is RED, BLUE, or GREEN
# 0 otherwise
sub red_green_blue {
local $_ = shift;
/\A RED \z/xms || /\A BLUE \z/xms || /\A GREEN \z/xms;
}
$array_of_my_very_own_types[23] = 99; # croak!
$array_of_my_very_own_types[2] = 'BLUE'; # OK!
Available at a CPAN near you!
