Spending a week teaching myself #Pascal because it's actually a great language with a pretty nice syntax if I can be honest.The type system isn't the best but hey it's a fun language and worth learning. I really have a thing for some of the older languages, there's something about them that just feels more right than those of the modern world.Don't get me wrong, there's a lot to love about #D with it's garbage collection, CRT for dynamic arrays and RTTI for managing OOP and polomorphism, VTABLES and the list can go on, but you can definately churn out good quality code in these older languages too.

AnsiStrings include what is known as a codepage which is technically something of antiquity. It dells the writeln() function which numbers map to which character and will actually translate those to what the VT100 terminal understands which is (thumbsucking) probably just our beloved UTF8 (with 99% of a guess).Antiquity, because these days to switch to Kanji we don’t switch codepages. We encode it all using the UTF8 codepage, but we hardly refer to it as a codepage as it is implied, we have all writing systemds in UTF8, no swithcing between encodings effectively.These strings are heap allocated and reference counted, so for the first part that means there is a length associated with them already on the heap table. The second part means that when the usage of the strings reach zero it will be free()-d.They are null terminated just for C cross-compat but these, as indicated in the documentation, are not used at all.

@deavmi if you were going to learn one of Rust or C++, I would just do Rust personally. C++ is nice, but has so much cruft. Standards committee really doesn't do enough. Then you have C++20 not even being fully implemented in any compiler.I think you might enjoy learning Zig though as a nice medium between Rust and C. I know I want to try it out eventually.

Perhaps Zig is my best bet.Yeah I asked about C++ knowing full well it's a living piece of trash. You simply don't need all those features. (Generics are ew), it also has streams?!?!?? Like bruh C++ is the one kid in the class that tried to be quircky and different but somehow became popular (in some timeline where hewas befriended), how this happens? I don't know I think it's more to do with C++ being the first to get OOP done as an extension to C, but I don't believe it was ever the best contender at least it could have been designed better (maybe not adding all the shit it has).

Okay, now this is great. String resizing is such a breeze when using the AnsiString type!That is so pleasing, now I can see why Araq (the developer of the NIm language) wrote the initial version of the Nim compiler in Pascal, it’s native and gives you this sort of nice features!

@colinsmatt11 @deavmi Starting about 20 years ago, Perl programmers recognized this problem and started writing code deliberately with fewer shortcuts for readability, as well as some aesthetics of formatting.You can make any language inscrutable to show off cool syntax tricks, but in my view, the best programmers use appropriate syntax and keep an eye toward readability.If you've ever had to maintain code you wrote ten years ago, you find that this approach has much wisdom!

I must say this is pretty interesting @caskd . It would appear Pascal provided a built-in method to do not just `Packing` which you can configure in most languages (I know you can in DLang) but also taking your `struct` and `BitPack`-ing it, which is nifty when the compiler automates it for you

@deavmi huh. I had a profess teach us about reference counting garbage collection after our University switched from C to Java (2001). Previously he had taught in Pascal (which they switched from years ago to C). I learned the hard way in an interview Java does not use reference counts. It locks and searches from roots (threads). His teaching makes more sense in this context. 🤔@caskd

The only thing with Pascal is it is overly elegant, it's hard to sometimes know what it is doing without seeing the implementation. In C you can easily now because of what data you are passing around but here, for all I know shit could be heavily macrotised, which I believe it is for many fucntions that work on a set of types.C isn't that heavily macrotised, then again it doesn't have dynamic arrays built in. But comparing to D, D doesn't really have macros but seperates the static arrays from dynamic ones in terms of functions etc, so it is more clear cut.

After having used Java for many years now, I was not even aware of that! I should get back into it, it can be an annoying language at sometimes but definately one I know how to use.I do recall them using some cursed as fuck string encoding though, like internally. It wanted to make me gorge my eyes out, it was like fucking spiced-up UTF16 or something

@deavmi It's been a long time since I looked it up, but IIRC, Java does a global lock, and a search starting at the entry-point (main) and all the Threads, and marks everything it encounters and GCs the rest. It has ways of determining which objects are long lived (like DB pooling objects for example) and marks them in such a way so they're not searched each time. (There's like .. the Eden space? and some other terms determining objects average age). So with such a system, you avoid memory leaks that occur when two objects reference each other but aren't referenced by a running thread (A has a reference to B and B has a reference to A, like with double-linked-list objects. The main function sets A = null. With reference counts, that would be a leak. When you search from the roots, they'd be unmarked and would get reclaimed).There have been a variety of different garbage collectors added to the JVM more recently. I haven't really kept up.@caskd @djsumdog

**Public Service Announcement** Remeber to set the VTABLE pointer for your function! If you don't implement it is will crash as the address is not valid!

There are two ways of doing object-orientation in Pascal today we did it using the so called object method, tomorrow we do it using this method shown below - the class method:

I’m now busy with getting used to the Free Pascal standard library and I must say it is very good, the unit Unix and UnixBase is great and basically mirrors glibc!

Programming in Pascal can actually be fun, now it's strongly typed but there's a huge load of types so it can be confusing what each is doing but the docs are there and you can make clever guesses too based on them.I had fun using the BaseUnix and Unix units (modules). I was able to map a bunch if memory in using the mmap() system call - as great test of a language is how easy one can do this.#programming #language #pascal #linux #unix

So in Free Pascal when using Delphi-Classes, if you don’t use the override word then it doesn’t switch out vtable pointers for said function and you are left, in this case, with the one in the parent class but which is abstract so that vtable pointer is most likely nilThis is what we see here.

We can also check the run-time type information of an object (whether the type given is in the tree of types of descendence of this object).

Static initializers and destructors! These let code run on static initialization of classes, which will happen during the unit’s (unit)’s initialization and likewise with the unit’s destruction.

It would seem that there is no implicit super constructor call in Delphi/Object Pascal mode in Free Pascal, so one must add it themselves if you wish to have that.
