> … so that, when you look at an image, or when you use it, browse the code, you can easily see what are changes and what is the base image… You seem to be asking about something that is in documentation from 1984. http://stephane.ducasse.free.fr/FreeBooks/TheInteractiveProg... > i am not suggesting that smalltalk needs to be changed… Smalltalk has been changed, several times. "With ENVY/Manager the image becomes a discardable by-product of development, secondary to the repository that stores and coordinates all work." https://www.google.com/books/edition/Mastering_ENVY_Develope... "The way ChangeSets are created and managed in Cuis is different from Squeak." https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/ma...

https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev Download and search !Compiler in: ./Cuis7-0-main/CuisImage/Cuis7.0.sources :and you'll see the commented Compiler class source code: "The compiler accepts Smalltalk source code and compiles it with respect to a given class. The user of the compiler supplies a context so that temporary variables are accessible during compilation." It would be easier to install Cuis Smalltalk and use the Smalltalk browsers to explore the Compiler code.

Cuis shares the OpenSmalltalk Virtual Machine with Squeak, Pharo and Newspeak. Cuis Smalltalk was originally forked from Squeak Smalltalk. What sets Cuis apart from other Smalltalk systems is the focus on the original values of the Smalltalk project at Xerox PARC, and an active attitude towards system complexity: https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/ma...

The web version uses squeakjs and a 32bit image. There's also: https://github.com/nmingotti/The-Cuis-CookBook/wiki/Run-Cuis... And: https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/ma... Which points to 64 and 32 bit VMs: https://github.com/OpenSmalltalk/opensmalltalk-vm/releases The cuis smalltalk images are in the repo, eg: https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/ma... https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/ma...

So there is [1] https://squeak.js.org/ and [2] https://github.com/codefrau/SqueakJS which seems to be able to not only run Squeak, but also [3] https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/wiki/Ru... and [4] https://github.com/carolahp/pharo to shrink and adapt these images to be able to run on common JS-runtimes in acceptable speeds and memory usage. There is also [5] https://caffeine.js.org/ and [6] https://github.com/ErikOnBike/CodeParadise bidirectionally <=> bridging the gap between Smalltalk and JS even more, with [7] https://www.webcomponents.org/ I think it should be possible to port, maybe to even have some hypercard-like visual website builder/explorable explanations thing.

To complement the Pharo recommendation, I would also recommend cuis smalltalk. It also forked from squeak, but went on an aggressive diet, shedding much complexity in the base image, and modularising (using git) much of the rest. Smalltalk newcomers may find cuis is easier to "digest" and get to grips with. Having used pharo and squeak myself, I find myself preferring cuis for more serious development. YMMV. - full instructions on install & first steps at [main cuis repo](https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev) - ["The Cuis Book"](https://cuis-smalltalk.github.io/TheCuisBook/index.html) - [cuis docs repo](https://github.com/Cuis-Smalltalk/Learning-Cuis) - [cuis related repos on github](https://github.com/search?o=desc&p=1&q=cuis-smalltalk&s=upda...)

I absolutely love the ethos behind Cuis Smalltalk[1]. It’s something I try to keep in mind when working on my own projects (though I’m not always able to be as strict!) I really wish I could stomach using Smalltalk for my own projects (beyond just exploration), but I find the VM is just too alien to be comfortable. If I could do it all from within Emacs I’d be delighted. [1] https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev#the-phi...

If you want something like Smalltalk 80, get Cuis. https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev

Didn't Cuis[1] branch off from Squeak even before that to be closer to its ST-80 roots. Although, if I recall correctly, it does at least use Morphic and not MVC. [1]: https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev

> All I can see in the terminal is a message about pthread_setschedparam failing, Just spotted this on Cuis smalltalk github page: "If you get this error message (you won't get it if you run Cuis as root or sudo): pthread_setschedparam failed: Operation not permitted ... Then you need to do this (just one time): sudo cp Cuis-Smalltalk-Dev/squeak.conf /etc/security/limits.d/squeak.conf Log out and log back in, or reboot the machine." Might be something similar for pharo? https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/ma...

This is lovely, we use Cuis University in the UNQ (and I know that it's used in the UBA as well), an argentinian university to teach OOP, and it's amazing how easy is to transmit the ideas. But also smalltalk in general is great to understand the full stack of a language, from the VM to the trivial libraries, including the GUI; and all using that powerful debugger! Cuis is a fork of Squeak, like Pharo, but simpler. Check it out https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev https://sites.google.com/view/cuis-university

I was going to say that it sounds a little like that Smalltalk IDE Squeak, and then it dawned upon me that this is actually a Smalltalk dialect too. :D I'm going to throw this in here: "Squeak or Pharo for the beginning Smalltalker?" https://stackoverflow.com/questions/8426981/squeak-or-pharo-... And a third option that is much leaner and maybe less overwhelming especially if you are interested in actually learning Smalltalk itself to begin with: https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev

For anyone interesting in trying out, here are the open source Smalltalk implementations available: Pharo [1] Squeak [2] Cuis [3] Note that these implementations have FFI and which you can modify / build shared libraries for. The creator of Cuis, who works at a satellite company, did just that by integrating OpenCL because he wanted the liveliness of Smalltalk. Cuis is also the most minimal of the lot.
