You have to understand that Perl 5 was released in 1994 (28 years ago as of this writing) and when we refer to Perl we usually mean Perl 5. That's many years, and there are many old scripts not following the modern Perl best practices (as they didn't exist yet). So yes, legacy scripts may be difficult to read. Japanese may be difficult to read too if you don't know Japanese, though.</span><br /> -<br /> -<span>To come back to the question: Is Perl a write-only language? I don't think so. Like in any other language, you have to apply best practices in order to keep your code maintainable. Some other programming languages enforce best practices, but that makes these languages less expressive. Perl follows the principles "there is more than one way to do it" (aka TIMTOWDI) and "making easy things easy and hard things possible".</span><br /> -<br /> -<span>Perl gives the programmer more flexibility in how to do things, and this results in a stronger learning curve than for lesser expressive languages like for example Go or Python. But, like in everything in life, common sense has to be applied. You should not take TIMTOWDI to the extreme in a production piece of code. In my personal opinion, it is also more satisfying to program in an expressive language.</span><br /> -<br /> -<span>Some good books on "good" Perl I can recommend are:</span><br /> -<br /> -<a class='textlink' href='http://modernperlbooks.com'>Modern Perl</a><br /> -<a class='textlink' href='https://hop.perl.plover.com'>Higher Order Perl</a><br /> -<br /> -<span>Due to Perl's expressiveness you will find a lot of obscure code in the interweb in form of obfuscation, fancy email signatures (JAPHs), art, polyglots and even poetry in Perl syntax. But that's not what you will find in production code. That's only people having fun with the language which is different to "getting things done". The expressiveness is a bonus. It makes the Perl programmers love Perl.</span><br /> -<br /> -<a class='textlink' href='https://en.wikipedia.org/wiki/Just_another_Perl_hacker'>JAPH</a><br /> -<a class='textlink' href='http://www.cpan.org/misc/japh'>http://www.cpan.org/misc/japh</a><br /> -<a class='textlink' href='https://www.perlmonks.org/index.pl?next=20;node_id=1590'>Perl Poetry</a><br /> -<br /> -<span>Even I personally have written some poetry in Perl and experimented with a polyglot script:</span><br /> -<br /> -<a class='textlink' href='./2008-06-26-perl-poetry.html'>My very own Perl Poetry</a><br /> -<a class='textlink' href='./2014-03-24-the-fibonacci.pl.c-polyglot.html'>A Perl-Raku-C polyglot generating the Fibonacci sequence</a><br /> -<br /> -<span>This all doesn't mean that you can't "get things done" with Perl. Quite the opposite is the case. Perl is a very pragmatic programming language and is suitable very well for rapid prototyping and any kind of small to medium-sized scripts and programs. You can write large enterprise scale application in Perl too, but that wasn't the original intend of why Perl was invented (more on that later).</span><br /> -<br /> -<h2 style='display: inline' id='is-perl-abandoned'>Is Perl abandoned?</h2><br /> -<br /> -<span>As I pointed out in the previous section, Perl 5 is around for quite some time without any new major version released. This can lead to the impression that development is not progressing and that the project is abandoned. Nothing can be further from the truth. Perl 5.000 was released in 1994 and the latest version (as of this writing) Perl 5.34.1 was released two months ago in 2022. You can check the version history on Wikipedia. You will notice releases being made regularly:</span><br /> -<br /> -<a class='textlink' href='https://en.wikipedia.org/wiki/Perl_5_version_history'>Perl 5 version history</a><br /> -<br /> -<span>As you can see, Perl 5 is under active development. I can also recommend to have a look at the following book, it summarizes all new Perl features which showed up after Perl v5.10:</span><br /> -<br /> |
