Is Fortran "A Dead Language"?
Looking at the activity on the Free Pascal compiler[0] compared to some other, non-dead languages like Crystal[1], I would say Pascal isn't dead.
They had a major release to their most popular IDE just a few weeks ago[2].
A lot of these projects built with FP aren't as visible in the HN community, because they related to different hobbyist fields, aren't keystone components in the startup ecosystem etc. But they for sure exist.

I come here not to bury Delphi, but to praise it (2019)
Free Pascal has fcl-web which should provide a HTTP/HTTPS client (among other things, it can be used to make web apps), though it comes with libcurl bindings out of the box so you could also use that too. fcl-json provides a JSON parser. FWIW "fcl" means "Free Component Library" which contains various tools (mainly exposed as classes).
The packages[0] directory of FPC contains a lot of stuff that come out of the box with the compiler and they often have an "examples" and/or "tests" directory with code you can check. There is some documentation[1] but sadly FCL is really not that well documented - you just have to check the sources for most things.
Note that this is for Free Pascal itself. Lazarus builds on it (LCL, the "Lazarus Component Library", is built on top of FCL) and adds a bunch of additional components of its own. Though usually for non-GUI stuff you just use the Free Pascal classes, Lazarus has some of its own "wrappers" that integrate with the IDE and the form/object designer. The "weblaz" package (it comes with Lazarus but you need to install it manually from Package -> Install/Uninstall Packages) provides a bunch of components for working with the web (mainly for making web apps), including the "TFPHttpClient" component which can be used to make HTTP requests. As a simple example, if you throw a TMemo (multiline text editor) control in a form, throw a TFPHttpClient component and then doubleclick on the form to edit the code to execute during the form's creation you can type "Memo1.Text:=FPHTTPClient1.Get('https://news.ycombinator.com/');" and it will put the HTML code for this forum in the memo (note that you may also need to add the opensslsockets unit in the uses section at the top of the code). Of course that is a very simple example but if you browse the properties and events of the component in the object inspector as well as the available methods by typing "FPHTTPClient1." and pressing ctrl+space in the code editor you can find most of the other functionality the component provides.

Web target – progress and plans
We’ve encountered FPC issue #40229 (Wasm32 symbol xxx without index value error) but it is now happily fixed :) Many thanks go to Nikolay Nikolov from FPC team for fixing, and Andrzej Kilijański for preparing a code to easily reproduce the issue.

CSVDocument Unit
No sure what you mean with "some sight", but the whole source code can be found here: https://gitlab.com/freepascal.org/fpc/source/-/blob/main/packages/fcl-base/src/csvdocument.pp

The project with a single 11,000-line code file
In Pascal that is really common, since the files are the modules. You publish your library as one file, and the user can import it by the file name.
I ran wc on FreePascal to search for some. There are a few, but not as many as I expected.
9k file, data structures for the compiler itself: https://gitlab.com/freepascal.org/fpc/source/-/blob/main/./c...
30k file: Pascal parser/scope resolver: https://gitlab.com/freepascal.org/fpc/source/-/blob/main/pac...
And the record:
119k file, Sharepoint API (but it seems to be autogenerated): https://gitlab.com/freepascal.org/fpc/source/-/blob/main/pac...
As far as libraries go, this is one of my favorites:
23k file, regular expression library: https://github.com/BeRo1985/flre/blob/master/src/FLRE.pas
I searched my own files and found a 197k file to parse HTML entities. But that was an autogenerated trie (one switch/case for each letter)

Re: Zlib memory corruption on deflate (i.e. compress)
I wonder if FreePascal is affected
Looks like they ported zlib to Pascal in 1998 and left it pretty much unchanged:

Is Fortran "A Dead Language"?
The Castle Game engine is not mentioned often, but it looks pretty mature from the screenshots and has been in active development for many years. Most recent news update was a few weeks ago. I have not gotten around to try it yet. Only started playing around with FreePascal a bit last year after not having used Pascal at all for some 25 years.

Modern Object Pascal Introduction for Programmers
This is a nice introduction. Apparently the author also implemented a full game engine in Object Pascal: https://github.com/castle-engine/castle-engine/. I wonder whether the performance is sufficient; according to available benchmarks (e.g. the CLBG) the code generated by FreePascal is about three to four times slower than C/C++; does anyone have experience with it?

Web target – progress and plans
Trung Le (Kagamma) has been doing lots of work with CGE + FPC WebAssembly. His fork contains a branch wasm32-wasi-port with lots of active work. I absolutely expect that we’ll merge it to CGE webassm\platformer\test at some point, and then to master branch :)

International fonts improvements: better sizing properties, better IME support on Windows (to input e.g. Chinese in TCastleEdit), better example
.2. With big thanks to Freedomax, our TCastleEdit now works with Windows IME much better. The IME popup appears at a proper place, and is thus visibly associated with the input box. This is great for languages relying on IME for input, like Chinese. See PR 457 for movie how it looks.

What is a better option to learn, C++ or C# ?
Delphi is a good language to learn. Compile fast to native machine code. C++ compiles slower and C# has garbagecollection which can cause hickups. Game engine in Delphi https://castle-engine.io/
What are some alternatives?
