pldb VS squeak.org

pldb.pub

How does it compare to https://pldb.com ?

Good Catch!

Updated here: https://github.com/breck7/pldb/commit/312d5dab32fda3782e8466...

We had this but the title was set to "xtclang". Just fixed (https://github.com/breck7/pldb/commit/1673baa00e5d44e7fd8ac9564480d6301063aa25). Thank you!

Don't have time to install but I would pay $10 in NEAR coin if you can email or post the results of my repos to me ([email protected]):

Interesting! I built a new system from the ground up for this sort of thing called TreeBase. It powers PLDB.com (https://github.com/breck7/pldb).

I don't have much experience using GraphQL. Is it a fun language to use? I wonder if we should provide a GraphQL API to PLDB.

Ok. Thank you! I just swapped with your code: https://github.com/breck7/pldb/commit/42d5562583e18fd141b979b16d30a8a4d7c5619c

Also, it's not really an "operating system", nor was it implemented by the ST. It's just part of Squeak (you got the name right), the "engine" Scratch 1.x was made with (which lets you edit the code in the same window it's running in).

Just downloaded https://squeak.org/ to play around with this concept.

I wonder if there is already a modern tool/suite for Node/Python inspired by Smalltalk...

AFAIK the major SmallTalk distributions are https://squeak.org/ and https://pharo.org/. I've heard that Pharo is more complex and "practical", while Squeak is more educational and beginner-friendly. But both stick to their roots with "everything is an object or method", extreme reflection, and integrated runtime/IDE.

Your concept looks nice, it reminds me a bit of the Lisperati: https://www.hackster.io/news/the-lisperati1000-is-a-cyberdec...

So, did you consider Lisp or maybe Smalltalk? Plan 9 or Inferno might also be options.

Plan 9 comes in different variants, the "classic" one (with a Raspberry Pi port by Richard Miller) or 9front, an Inferno porting tutorial can be found at https://github.com/yshurik/inferno-rpi

Lisp and Smalltalk can run with or without Linux underneath, e.g. on the Raspberry Pi.

Bare-metal Lisp is available with interim: http://interim-os.com

Finally, bare-metal Smalltalk is available in my crosstalk system: https://github.com/michaelengel/crosstalk

Of course, Lisp and Smalltalk can also run hosted under Linux, e.g. using Squeak (https://squeak.org), Pharo (https://pharo.org) or InterLisp (https://github.com/Interlisp/medley).

Or - a crazy idea - build an emacs-only machine. That would be fun! :)

This repository contains multiple projects closely related to (hardware-accelerated) rendering in Squeak/Smalltalk.

Packages related to using OpenGL in Squeak/Smalltalk.

Author here, feel free to ask any questions you have :).

It's amazing this little project shows up again here. So far, I received a lot of very positive and friendly feedback about this little pet project of mine.

The whole project would not have been possible without the work of Rene Stange, who created the circle bare-metal library for the Raspberry Pi (https://github.com/rsta2) and Dan Banay, who created a C++ implementation of the Smalltalk-80 VM (https://github.com/dbanay/Smalltalk). I mostly hacked together some glue code...

If you want to dig deeper, the Blue Book by Adele Goldberg and David Robson (scan provided by Stephane Ducasse, thanks a lot!) is _the_ reference on both the language and the structure and implementation of the underlying bytecode VM: http://stephane.ducasse.free.fr/FreeBooks/BlueBook/Bluebook....

Beware, though it's fully functional, crosstalk is still limited by constraints of the original Smalltalk 80 system - e.g. in terms of color (black and white only), possible screen resolution (2^20 pixels, the system crashes if you try to increase the resolution beyond this) and available memory (~1 MB!).

Nevertheless, I think it's a rather authentic reproduction of a more than 40 year old system and I learned (in a comment thread on a completely different topic) that one of our fellow hackernews regulars used it to teach his kid Smalltalk programming - love it! I haven't tried to optimize it significantly, so there's no JIT compiler or bitblit acceleration using the Raspberry Pi GPU.

There's a more modern bare-metal Smalltalk implementation based on Squeak (https://squeak.org) for the Raspberry Pi by Pablo Marx, though this seems to have some stability problems according to the author: https://github.com/pablomarx/RaspberrySqueak

Finally, if you are interested in alternative bare-metal language/OS environments for the Raspberry Pi, you could also give Lukas Hartmann's (of MNT Reform notebook fame) Interim OS a try: http://interim-os.com

Came here to mention Smalltalk. In things like Smalltalk-80 and Squeak, there was no build system, there are no source code files, there isn't anything but the Smalltalk Development Environment. With something like ENVY/Developer, building involved generating an exported image from the environment.

If OP wants to try it: https://squeak.org/

She missed the biggest ‚programming portal‘ of all: Squeak (Smalltalk) (https://squeak.org/)

Inspecting objects, ‚live‘ coding, a GUI that's intimately tied to its CLI - that's exactly Squeak!
