Advent_of_Code_in_Pascal VS mORMot2

I'm doing it in Lazarus/Free Pascal again.

Free Pascal - 2251/1744 34.5 seconds runtime No objects, no recursion After brute forcing part 1, I stared at part 2 until I though only handling the different values of X,Y,Z and letting the grid represent variable size cubes.. only to hit memory size limits anyway... and then I learned how to use BITPACKED array, and was able to eventually brute force part 2. Whew!

My pascal based solver eventually got valid text out of your input.

This article reads more like an ad for mORMot 2 than Pascal. I've been out of the Pascal game for a few years, so I had to look up mORMot 2.[0] Apparently Synopse are the maintainers of it.

The article basically compare their CSV/JSON serialising library to Go's standard CSV/JSON libraries. Looking at the Go code, it's pretty clear why it has memory issues, it reads all the lines into a single object (well, `[][]string`) immediately, rather than reading line for line (which takes advantage of the stream).

I am not sure how this is remarkable and impressive for Pascal. They talk about how you don't need to use the `try..finally..Free` routine all the time, but that's only if the object in question is an interface. Interfaces are somehow handled by a reference counter in Object Pascal, so you need to know how to operate on objects vs interfaces, because they act very different. Pascal is full of these quirks.

The most powerful and stable web framework is mORMot, it supports both FPC and Delphi. Here is its version 2 in development: https://github.com/synopse/mORMot2

I use Delphi all the time, IMHO, it's the best tool for Windows desktop app development - concise language, blazing fast compile time, easy UI design, flexible UI framework, all-in-one IDE, and so on. It's joy to me :)

And here is my new desktop software written in Delphi: https://docxmanager.com/
