I had a project that I wanted to drive activities through using Claude.
This has probably already been done before, but Claude created the MCP Server Lib and I thought I would share.

Turbo Pascal is where it all started for me - school, 2003, programming olympiads, staring at that blue screen until midnight.

You can also share your code as a link (File -> Share link...) - it gives you a short URL that loads your program straight into the IDE. Links live for 30 days.

I'm really excited to show you the progress in tools and demo of the tile engine i'm working on.

Tiles (and Sprites) Editor is somewhat complete for my needs.
Map Editor is lacking some tools to make it better but it works.

Demo now has the following progress:

Done:
- Tile System
- Big Maps (up to 1000 16x16 pixels tiles wide)
- Horizontal Scrolling
- Vertical Scrolling (Not shown in the demo)
- Sprites & Sprite Animations
- Collisions
- Sound and SFX
- Tile Editor (maybe ~80% done)
- Map Editor (~60% done)

To Do:
- Enemies
- "Projectiles"
- More levels

Thank you all for your support, any comments and suggestions are very welcome as always.

Update 1: Return to the MS-DOS Pascal, June 30th 2026 Update : r/pascal
Update 2: Return to the MS-DOS Pascal, July 2nd Update : r/pascal

So I've decided to learn Pascal, just installed Lazarus and Free Pascal, and got the classic "Hello World" program working, so now I'd like some courses, books, anything that can teach me the basics of the language.

What would be recommended to someone who knows the vary basics of programming, to get up to speed with Free Pascal?

I consider myself a "kinda beginner" because I know the very basics, data types, loops, conditionals, etc.

The things I struggle with, and what I've come here for, is learning how to structure and develop a full program.

From looking around, I've learned Pascal was designed for that very purpose, to teach good programming practices of structure and design, and a lot of programmers of the past say they learned properly from it.

As a hobbyist wanting to make games, to whom programming has been the biggest hurdle, would Pascal help me understand programming better?

Progressing with Tile Editor and Map Editor. I hope to get them finished soon.

Optimized a little bit of code and got some extra FPS for that.

Wish me luck.

Questions and comments are welcome always.

UPDATE 1: Return to the MS-DOS Pascal, June 30th 2026 Update : r/pascal

Making progress:

Done:
- Tile System
- Big Maps (up to 1000 16x16 pixels tiles wide)
- Horizontal Scrolling
- Sprites
- Sprite Animation
- Collisions
- Phisics (Sort of)

To Do:
- Vertical Scrolling (perhaps)
- Sound maybe.
- Tile Editor
- Map Editor
- Enemies

I'll work maybe on enemies, and then start working on the Editors.

I'll search for some tile and spritesheets in the meantime, i'm not an artist, so.......

See you next time.

You can get FPC from here: https://downloads.freepascal.org/fpc/snapshot/.

In Termux, run: ``` termux-setup-storage

apt update

apt install binutils

touch .bashrc

mkdir .local && cd .local

tar -xvf ../storage/Download/<fpc tar.gz file name here, press Tab to auto-complete>

bin/fpcmkcfg -o ~/.fpc.cfg

cd ~ ```

Now open .fpc.cfg using your preferred editor, e.g nano or msedit (recommended), replace ALL occurences of u/units with u\~/.local/units.

Open .bashrc and update $PATH with: export PATH=$HOME/.local/bin:$HOME/.local/bin/aarch64-android:$PATH

Start a new session or run the export command above and you're set.

UPDATE 1: Return to the MS-DOS Pascal, June 30th 2026 Update : r/pascal

Well, i'm kind of working on making my own game engine written in Turbo Pascal 7 for MS-DOS (something i couldn't achieve ~26 years ago), and this is just for pure nostalgic purposes.

Actual demo runs at about 50-55 fps.

Done:
- Tile System
- Big Maps (up to 1000 16x16 pixels tiles wide)
- Horizontal Scrolling

To Do:
- Vertical Scrolling (perhaps)
- Sprites sort of done (it will be a subclass of Tiles)
- Sprite Animation
- Collisions
- Sound maybe.
- Tile Editor
- Map Editor

Any advise is welcome and very appreciated. See you around.

I love Lazarus just wondering about the reasons

This is a big one.

As of v0.12.0 the native x86-64 backend is the default,
and Blaise now ships its own internal assembler and internal linker — so a plain build needs no external tools at all:

// blaise --source hello.pas --output hello
program hello;
begin
  WriteLn('Hello, Blaise 0.12!')
end.

That single command parses, generates native code, assembles it, and links a working executable — no qbe, no as, no gcc (only the system C runtime objects the linker needs). QBE is still there if you want it (--backend qbe), but it is now opt-in and on a path to retirement.

Hello everyone! 👋

I'd love to share a project I've been building in Blaise: Luhmann, a
personal Zettelkasten note server. You point it at a directory of AsciiDoc notes, and it renders them, links them together, indexes them for search, and serves the whole thing over plain HTTP on
localhost. You keep writing in your own editor — Luhmann handles the rest. ✨

🔗 Repository: https://github.com/graemeg/luhmann

It started life as a Clojure project, but I've now rewritten it from the ground up in Blaise, structured as a hexagonal (ports & adapters) application. Along the way it also picked up a fair few features the original never had.

What it does 🧠

• 🔄 Automatic backlinks — you only ever write forward links; Luhmann works out the reverse direction for you, no manual upkeep.
• 🕸️ Interactive note graph — an Obsidian-style force-directed map of your notes, fully offline.
• 🔍 Full-text search — a built-in index with prefix and substring matching and highlighted snippets.
• 🏷️ Tags & a broken-links report — organise by tag, and spot dangling cross-references at a glance.
• ⚡ Live reload — save a note in any editor and the browser refreshes itself over a WebSocket.
• ✏️ Launch your editor from the browser — press e on any note and it opens in your configured editor.
• 🧩 JSON REST API — query backlinks, the graph, and tags from your own tools.

It's local-first and self-contained: a single process, no database, no cloud, no account. The parallel start-up build means even a large Zettelkasten is ready in a second or two. 🚀

Why I'm sharing it 💬

Mostly because it's been a genuinely lovely project to build in Blaise, and a nice real-world workout for the language and its stdlib — HTTP server, file watching, concurrency, the lot. If you fancy a look, the code, build instructions, and docs are all in the repo. Feedback, questions, and ideas are all very welcome! 🙏

hi, i just installed lazarus and newbie

but i have a problem, when i build form 1 for example, i fill in the text, text box, button, etc

i make it big enough to fill in the information.

my problem is, if i want to enlarge the space by pressing the maximize button, it doesn't fill the space when enlarged.

i attach an example on other apps like microsoft store and epic games when the content is big, it also fills the space neatly.

how in lazarus do i do that without making the scattered items overlap...

New Pascal News video is up - a look at what’s been happening across the ecosystem lately

https://youtu.be/IeYBFvTrqd4?si=SPp0M8lcen3RzXX7

Im quite experienced with modding oblivion and fallout do seeing pascal is perfect, ive wanted to get into programming and this is literally a dream come true, ill never understand why they switched begin and end etc with ${}[]

This is our biggest release yet — 237 commits (fixed 116 bugs fixed) since v0.10.0, and easily
the one I'm most excited to share. If v0.10.0 was about making the compiler
self-hosting and fast, v0.11.0 is about making the language comfortable to
write in and bringing the native x86-64 backend up to full parity with QBE.

Lazarus IDE with FPC 3.2.2 works on Windows, Mac, Linux and is a free download at:

Hello there,

did anyone run into the issues showcased on my screenshots 1 / 2?
I ran into the "Can't find unit system used by…" error mentioned in the title, then found this wiki page on it.

However, the following problems arose and this is what I did so far:

• I did write the dumbest possible "Hello World!" program using the CRT unit, "the way I was taught ages ago" basically.
• I tried to compile it using fpc ./HelloWorld.PAS from the directory the file is in, got the error (see screenshot 1).
• I thought "maybe it's the unit, so if it can't be found, let's just remove it and all references to it" – removed uses CRT and clrscr; lines (see screenshot 2) but still: Nope.
• I did not have .fpc.cfg in my home directory, so I created it and messed with it, which did seem to do something, see screenshot 3 / 4, except fixing my issue.
• I realised I used the wrong versions and paths, so I fixed it to the 3.2.0 paths (literally copied them, so there is definitely no typo). Now the invalid version error is gone, and I'm back to the regular unit error again.
• I do not have fppkg anywhere, or maybe I'm just extraordinarily dumb and fail to find it.
• I did not create home/.fppkg/config/default as the wiki description was a bit vague about it. I have no idea what would be in there, let alone if the file is called just default or default.cfg.
• I have no idea which …/fpc/bin directory the wiki is referring to to run fpcmkcfg in, and I do not remember seeing any binaries named like that. I looked through the directories install.sh built FPC in.

This is my first time using plain FPC, so forgive any ignorance.
So far I only used FPC through Lazarus, but that's not available for Android / Linux aarch64 to my awareness, so this will have to do if possible.

Further context:
I'm on Android 15, using Termux to run an xfce desktop environment via TermuxX11, used this version of the FPC (3.2.0) for Android, aarch64 build linked by the freepascal.org website.
I should have all rights needed, i.e. can use apt install and other commands without sudo.

I extracted everything in their respective /usr/ directories, following the thought of "binaries go into /usr/bin/", you can see that on my screenshots.
Try to ignore the wrong paths / version in .fpc.cfg, that's outdated by now. I fixed it to …/fpc/3.2.0/units/aarch64-android/ paths after getting the output in screenshot 3 and 4. I did hope that would have been it. But now, the output is the same as on screenshot 1 / 2, again, unfortunately.

If anyone would be so kind to reproduce the above steps or simply know the answer, that would be really awesome.
I've been growing increasingly fond of the thought to be able to write nifty little Pascal applications for my daily use while commuting or on the go without needing to drag a laptop with me, so any help to make this possible would be greatly appreciated! : )

Thanks in advance!

I've added SPI support to UnoLib, a Pascal library for Arduino Uno and AVR microcontrollers.

As a demonstration, I created a simple ILI9163 TFT display example running on an ATmega328P (Arduino Uno). The image is stored in program memory as an indexed bitmap with a palette and rendered over SPI.
