hi, i was interested if perl is still relevant in this day and age. Perl has been on the decline for a very long time now. Perl 6 (now named 'raku) not being backwards compatible with perl 5 code made the already small perl community even smaller by splitting it in half. A good example is lisp with it’s thousands of different dialects.
Is it still worth using or is it bound to legacy software forever? Like cobol.
I write Perl at work. Supporting an actively developed Perl based application.
It’s honestly not that bad as a language, the biggest downside is that the ecosystem of libraries around it are often abandoned or outdated. The language isn’t perfect and it needs a bit of discipline to avoid creating unreadable code, but honestly it’s not as bad as its reputation might have you believe.
It has quite a few tricks and unexpected bits of flexibility that make it quite a bit more expressive than other languages - you can really craft nice compact, elegant code with it if you want to.
These days I use other languages too (Python, Ruby, JS, etc) but none of them quite match Perl for expressiveness.
Oh also it’s great for oneliners. That expressiveness can be abused for brevity in some really interesting ways.
The worst one I stumbled across while reading a colleagues script was the three separate namespaces for symbols of type scalar, array, and hash.
You mean the fact that you can have a hash called %foo, an array called @foo and a scalar called $foo all at the same time? I agree that’s a weird choice and there’s potential for insanity there, but it’s pretty easy to just not do that…
20+ years of Perl experience and while Perl has a load of idiosyncrasies that make it harder to work with than other languages, I don’t think that particular one has ever caused a significant problem.
Yes, exactly. Those definitions aren’t clashing, so they must have separate namespaces.
I wouldn’t do that either, but my colleage apparently did. So far I’m having a harder time reading perl than writing it.
Do you work for booking.com? Only place I’ve seen that advertises the fact they run on a perl codebase
Nope. But I know a bunch of people that do or have, and have interviewed several (it’s a pretty small sector!)
