Yup, it's still used plenty in banks and fintech, but it's going the way of COBOL. Which I guess means I will finish my career as one of those weird old programmers who has perfect job security maintaining some bank's legacy Perl system. Perl rocked, but Python won in the end. I can't see how it would be worth starting a career in Perl today, unless your company already used it. Also, hi fellow Perlmonks dude! That was an amazing place for a while. Especially when a bunch of people were on there recommending everyone learn Scheme, and that taught me how to program properly, finally.

It might be a good place to work if you like perl. larry wall worked at a lot of places - from what i can tell, pretty much any perl project that got big and gross enough hired him on at least as a consultant you know what, maybe i'm thinking of randal schwarz. all i know is that one of them worked at a previous job (well before i worked there though)

I’m surprised print isn’t trying to use reverse as a filehandle and output to it. I used Perl professionally for a decade+, and I’m still surprised by the semantics at times. It’s one of my favorite languages, but it’s a bad language to build software in.

I am actually starting to like perl for things like data-wrangling way more than using, say, something like bash. Kind of in a weird phase of learning this for professional work but it also pays off that its just included in most *nix operating systems anyways.

Ruby and Python are better languages for building software, but for throw-away Unix command line uses you really can’t beat learning either Perl or Awk+Sed.

Ruby probably isn't better than Snek for its objective--I don't think it would run in 2 kB RAM. Python wasn't a bad choice to base Snek on. It is a relatively small language. I'm kind of surprised they didn't just roll with Lua and call it a day, but Lua is weird too.

In a Perl shoppe now. The product seems to have exactly the same level of technical debt and under/over designed issues that I've seen in Java and Python heavy solutions, but the language seems a good fit to focus on the data being managed. Even the newer PMs look at the code, so there don't seem to be many learning troubles. Sadly some of the long tenured people are wrong on some of the details and reluctant to make improvements.

I taught myself Perl last year because I've been using Linux a lot more and Perl comes in the standard Debian install. I've used it for a few things because it's honestly the fastest thing I know how to use for doing text stuff and it's also pretty easy to use to send arbitrary stuff over IP sockets. I don't like how it handles function arguments but at least the stuff I write is so simple I don't need functions. A+ would recommend if you have it sitting on your hard drive anyway

Ooo part of an RPM even. I haven't dinked with building RPMs in about ten years. Bash takes a different mindset; it can be a fun exercise. Here's a fun one I didn't know until recently. You know how sed has a range operator, such as /open/../close/d ? It bleeping exists in Perl as well.  In list context the .. range operator generates the range, duh, but in scalar context it's a boolean flip-flop operator. You can even do !defined(blah) .. /regexp/ and similar things, multiple instances without collision (ie nested loops work).

Feral Integral posted:I never bothered with ruby, beyond reading about ror stuff like a decade or so ago. Curious as to why you think its a better language than snek Rubys strength is its weakness. Its really great for defining little DSLs in and creating highly magic based libraries. The problem with magic though, is when it goes wrong, its loving impossible to debug. And Rubys killer app, Rails, was the king of that. If you made a NATO standard regulation web app, that wasnt too dependent on its awful ORM, it was phenomenal. But as soon as poo poo gets weird in your requirements and you have to color outside the lines, Rails kinda falls apart conceptually and suddenly those neat natural-languageish lines turn into a metaprogramming clusterfuck Productiveity wise though it'll clean the clock out of any language you could throw at it. Honestly, the hipsters abandoned Ruby for NodeJS because most of them are loving stupid. Its no wonder Python took off. NodeJS creates unmaintainable messes, and Rails just isnt cool anymore. Python was innevitable (yes I know its probably the oldest language of all of them. The hipsters dont know that) duck monster fucked around with this message at 15:31 on Oct 27, 2023 |

It’s fun to think about the evolution of languages, and how each evolves to fit a niche, and has to continue to evolve or die. Perl 5 lost almost ten years of progress when it decided to put all changes on hold while waiting for Perl 6, and that’s when Python and Ruby just took over.

Perl diving headfirst into the Osborne Effect and then sleeping for a decade certainly didn't help, but I agree that the core reason Python and Ruby took over is because they have easier to read syntax. TMTOWTDI is a great philosophy until you discover it means to understand everyone else's code that you need to know every dark corner of the language; and that's a huge drag on adoption in every niche outside of single-maintainer/one-off scripts.

But this is the Perl thread, so we love Perl here. As with any language, you get to maintain crap code if you write crap code, but when you adopt better patterns you get to enjoy beautiful code. Perl, as many like to point out, has more than one way to do things, so you are free to adopt a code organization and presentation that matches the needs of the project. Procedural? Yep. Class based? Yep. Functional? Yep. Loaded up with 75 libraries and three lines of code? Yeap, even that. It's so straightforward - rather, conditions, loops, flow control, are "universal", duh - that I worked with TPMs who filed ticket requests with code details and references. I never saw that at the Python, Ruby, and Java shops. They couldn't even find the relevant code.

The Benchmark module has a subtle imperfection: It finds a baseline runtime for an empty eval based on the type of underlying tests but does so only once. Delays at that time may result in later runtimes being reported as negatives, particularly when using the direct timing functions (instead of cmpthese). Obviously benchmarking comes with a ton of caveats, but it's common to build representative baselines, which themselves require statistical measurement. Reporting and subtracting that runtime is likely to make more sense when performance profiling compared to getting some tests with negative average runtimes. I really like how easy it is to quickly benchmark in Perl but this was an interesting choice. If you see some negative times when using the timing functions of Benchmark coupled with timediff, this is the likely culprit. It's much less likely that your clock is jumping backwards.

In 1997 I got my first digital camera. I also discovered ImageMagick and perl that year, and so I built a basic image processor out of perl and Image::Magick to automate managing my photo folders of JPEGs and generating thumbnails and HTML catalog views I could view in Netscape. Almost 30 years later I still use and tinker with this system, but now it lives on a server on my network and manages a photo collection of 400,000 images I've taken in the decades since. It handles archiving and metadata for all my terabytes of raw source files, version control for edited 16-bit wide-gamut JPEG2K master versions (from Photoshop and Lightroom), and still after all these years it uses the ever-dependable Image::Magick to export a variety of viewing and sharing versions of the masters in standard formats and color spaces. It's all glued together with watch folder automation. I still consider it a perl project though in recent years a couple of heretical python plugins have crept in to use some AI models for auto-generating keyword search terms and image descriptions, recognizing people and tagging features and regions of interest.

Tis interesting that pointers will always cause problems for programmers. One of the most frequent syntax questions I get from our software peeps is their confusion about accessing things in basic and object types. They get confused because there are lots of places in our code where people have chosen to use references and arrow dereferencing. I get the impression that the mid engineers really don't know what's happening and are just trying things until it works. Sadly, but I still see lots of ahha moments when people are sharing examples, doing code reviews and the like. It's amazing how consistent the original syntax is after all these years and language requests.
