Re: My progress in Perl

[Levi Elias Nystad-Johansen via beginners]

Hi,

Learning Perl is a great book, but anyone looking for an alternative should 
check out Minimal Perl by Tim Maher. I've found this book to be a little 
clearer and with more practical examples.

I've used Perl on windows for years, as it is far more powerful and portable 
than Batch and Powershell. Of course I also use it on mac and linux, and I can 
use the same scripts on all platforms :)

Most of my coding has been in making small command line utilities.
Like a script for renaming multiple files at once - which I use a lot for 
renaming photos from my camera and downloaded movies.

And one that runs a command whenever a file changes in a directory - I use this 
all the time for automatically running tests when I make changes to a code base.

I also use perl every time I need to process or generate reports.

While other languages, like python, offer more employment opportunities, I 
don't see myself switching. Perl is simply better and more suited for the tasks 
I use it for.

Perl has stronger regexes than anything else, has custom delimiters to avoid 
leaning toothpicks and similar issues, and allows for quick building and 
manipulation of strings, lists, and hashes.

My problem with Python (beside my inability to think oriented object) is
the very bad choice to have idents to represent blocks hierarchy.

In my every day work, I often write scripts I will use only once, and I
reuse pieces I copy from other script.

As it is onetime use only, I don't care about the identation, I just cut
and paste from { to }. I am not sure Python would react nicely to a
nightmare of identation.

RE: My progress in Perl

[Claude Brown via beginners]

Steve,

I agree.  Someone just starting out should go with Python.  It pains me to say 
it, but Perl isn’t a good skills investment.

My team and I program every day in Perl – we have 100’s of libraries and system 
integrations.  I love it and it is my first choice for backend work.Sadly, 
we are trying to figure out our path to Python.  We barely know Python, so it 
will be a difficult – but necessary – journey.
Cheers,

Claude.

Honestly, my advise is if you are beginning to learn programming using perl in 
2023. Don't.
Pick up python and go from there.
If you already know some perl and want to advance, yes go right ahead.
2023, is perl dead? no. It's a tool and it's still a swiss army of programming 
language and lot can be done.
I would say writing concise and compact programming for regex related 
processing, it still is right up there with anything out there today.
But def if you are learning programming in 2023, you should start w/ python.
To be truly useful, you have to learn several language but python(or to lot of 
extend, javascript) should be the first language you should learn(until AI can 
take over the world).

Having said this, I still love my perl.

Re: My progress in Perl

[armando perez pena]

In my case Perl was my first programming language.  What I did was.

1) Read "Learning Perl" book.
2) After 2nd chapter more or less start to apply it and continue reading.

What I learned was applicable for other languages like python because the 
concept are similar.

But for sure you need a project where you need to apply it.

Once I read one advice. If you have doubt which language learn for example Perl 
and Python learn both. There is nothing bad with that.

Armando

That is great advice.  Write a program to open your directories
given a key word.  I use that program dozens of times every day.

William,

Beginning Perl of Curtis Ovid Poe.

I started with a lot of passion but then lost interest, the monotony conquered
me. Actually I am learning references and Complex Data Structures in Perl.

I never learned that in Perl and I have been using Perl for 25 years at
least.

I never learned Perl from a book either, I used it for some small
tasks/projects and learned new bits when I needed them.


I have a lot of doubts in my mind:

What is my purpose with this language?

For me, Perl is an unvaluable tool for automatisation of system tasks,
manage users, create accounts, etc. My last scripts are used to
synchronize print quota between two very dissimliar systems.


In my country don't exist use of this language
I am boring and tired

SpamAssassin is a large project in Perl, but even that is not using very
complicated data structures. Perl was designed to manipulate reports,
extract data and create new reports. It is not a general usage language.

I am not sure it is the right way to try to learn Perl without any
project. Try to learn by doing something that you need.

Most of the CPAN extensions (modules), you don't need them, you will
never need them unless you have a direct use for them. Also, depending
on the operating system you are using, some of the Perl modules may be
part of the packages distriubuted for your OS.

Also, for me the real strength of Perl is the strong system of regular
expressions, I have an extensive use for them in each of my scripts (a
software produces some logs, I have to extract some significant lines
from the logs, etc.)

Best regards,

Olivier
