Perl in 100 Seconds

IMO, the key to writing really terse code in Perl is $_ and the fact that you don't usually need to evern type it. It probably also makes code bewildering to people who don't know Perl.

Why did the Perl code break up with its girlfriend?

Because she said she needed more space, but Perl kept adding unnecessary complexity!

this aint 100 seconds 💀 100 seconds in 1 minute 40 seconds

OUR variable 🫱🐰🫱

Love the idea of "my" for local and "our" for global variable, makes it sound like a team project

The elements of an array or hash have the dollar sign as their sigils! It is not @nums[1] (that would be an array slice) or %friends{'Larry'} (that is an compile time error), but $nums[1] and $frieds{Larry}!

Why does it looks so similar to bash...

How about the video "Pascal in 100 Seconds"? 😀

They're not kidding about its string parsing abilities.

how it started: things that are different should look different
how it's going: things that are the same look completely different

Even after all these years still love unless

one great feature you didn't mentioned and probably because is an obscure one, is that when you read any data that is not local, like data from the web, Perl throws always an error if you try to use it without parsing it with regex. Perl forces you to parse input with a regex, Perl called this "tainted variable" so to untaint it you use the regex, and this made sites written in Perl a lot more secure than with PHP, and for many people this was one of the reasons to make fun of PHP. The problem is that noobs still wouldn't know what to look for with the regex, but it helped them to find the documentation to avoid sql injections.

I love perl, is one of the reasons I chose ruby over python back in 2004 because the ruby man page says "inspired by lisp and perl" and that was a selling point to me.

Once I had to maintain an email server written in Perl. It was a single file, 10,000 lines long. The worst language ever. I still have nightmares.

“I remember back in nahn-teen.”

I'm having flashbacks of that time I decided to use Perl to do my assignments in a CS low level graphics course (early 2000s). Definitely the wrong tool for the job, but looking back I think what held it back more was a lack of understanding good structure. Still, Perl/CGI is what got me into programming during high school, so it'll always hold a place in my heart. I just hope never to have to use it ever again.

Was the second "internet" programming language I learned. Was disappointed when I found out literally no other languages have reg-ex by default.

I know everyone dunks on cryptic Perl one-liners, but that's a design decision. It makes it so system admins can copy/paste whole ass programs them into terminals.

Nice

my exam is in 7 hrs and this helps❤thank youuu

I have a question, how perl can be an interpreter because it converts the code into byte code and then it is compiled into machine instructions. It has both interpreter and compiler features ? Can anyone clear my doubt ?

Interesting. I'd be curious to see an example of how good perl text processing is. I believe one of the design goals of ruby was simply to be a better perl: same text processing and array manipulation features but with a much more readable syntax. I wonder if it actually matches perl.

Nice description in a short time...

I don’t know why, but this language connects with me on a deeper level. I love the fact that Perl isn’t like every other programming language. It’s uniqueness is what makes it so beautiful. Graciously powerful.

I wrote a ton of Perl code in the late 90s into the early 2000s. I used it on web sites, in system administration, and in bioinformatics projects.

I'm here because Dustin Moskovitz learned this in 3 days with the book Perl for dummies.

Wow. This language is shit.

Raku is even better than Perl 6, it's like the production ready version at the end of the line of prototypes. I've found difficult to reach a conclusion about Raku thought, just because it has everything and them some to it, it's a really really feature reach language, and although I don't like it in languages e.g. C++, just because the language is always surprising you no matter how long you've been programming in it, Raku seems to have done many many things right.

As much as I love perl because idk it just seems to be easier to do things in it, autivivication does sound like necromancy.

Thanks. Now I"m a Perl expert.

I think Perl is super underrated

Perl Advocate: But does you language have...Autovivification!?!?!?!?

Average Developer: Well, considering that I haven't heard of that term until 1 second ago, no it doesn't.

Perl Advocate: Checkmate, bitch.

I hate perl and I had to deal with it in my first job to fix bugs left behind by developers who had left the company. It was awful.

Man, this was a blast from the past. I haven't written Perl code in nearly 20 years and completely forgotten how ugly it was. It definitely got the job done, though!

This is actually a better intro to Perl than most Perl books.

my brain feels like i just finished a Calculus lecture

Perl gets a lot of hate but it was one of my first languages and imho it's still better than JavaScript. That's not saying a lot but for some reason everyone seems to think JavaScript is a good solution for everything nowadays.

I spent around a decade working with an open source library system called Koha that's written in Perl. I'm still fond of it and the community, but Perl was never one of the pros.

How many of you think that he removes the code step by step and then just keeps on pressing the Ctrl + Z command throughout the video to undo the changes?

can you talk about Delphi next?

Not enough $&&&$$&&$$&&$$&😂

When I first met Perl, I got a veeeery painful headache just by reading the code. :-)

I remember from a vocational class where I learned Microsoft's Powershell. The instructor ranted about Perl for 10-15 straight minutes. The abridged version of this is

"Now Powershell has some influences, one of them happens to be a programming language called Perl. Perl was created by a linguist, as in not-a -programmer background kind of computer scientist wannabe, who has some mild obsession with Unix shell commands and a deep obsession with another programming language called AWK. He pretty much merged his interests with C and some other popular languages. So you can see a very tiny influence of Perl in Powershell. The bigger point is that Perl is so unusable for anybody today to the point that its steep learning curve indirectly inspired other programmers to develop more approachable programming languages for the market today. So, thank you, Perl?"
