> Is anyone else familiar with “modern” attempts at this? Glamorous Toolkit is the main one I have found, yah. The TruffleSqueak demos are pretty cool: https://github.com/hpi-swa/trufflesqueak Enso Analytics also runs on GraalVM: https://ensoanalytics.com/ Love the "Stop Writing Dead Programs" talk - and of course "Inventing on Principle" by Bret Victor is required viewing for anyone that hasn't seen it yet. https://youtu.be/PUv66718DII

> JS engines (which are descendants of the Self engine) are still significanly faster than Cog/OpenSmalltalk. This is almost entirely a function of effort expended. Several trillion dollar companies have large teams working on JavaScript engines, usually multiple engines each. The OpenSmalltalk VM is a volunteer effort of a very small community, with the main JIT produced primarily by a single person. "The F4 Phantom...America's proof to the world that with a big enough engine, even a brick can fly" https://www.youtube.com/watch?v=XqUgUgiToNs Fabio Niephaus hooked up Squeak to the GraalVM. https://github.com/hpi-swa/trufflesqueak Takes a while for the optimizer to reach a steady-state, but does it ever fly when it does. The Bouncing Atoms demo reaches around 10x the frame rate of the OpenSmalltalk VM. https://www.researchgate.net/public

I agree! Our work on TruffleSqueak [1] and on Polyglot Live Programming [2] has shown that it's possible to build language-agnostic live programming tools with GraalVM. If Espresso implements the required Truffle APIs correctly, our tools should also just work for Java. :) [1] https://github.com/hpi-swa/trufflesqueak/ [2] https://github.com/hpi-swa/polyglot-live-programming

Thanks! > I vaguely recall some mention in one of the docs I read a while back that you were having difficulties with the JIT causing noticable pauses/latency in interactive environments like Morphic, comparison to the OpenSmalltalkVM. Right, have a look at the sub-discussion at https://news.ycombinator.com/item?id=24182587. > Am I recalling correctly, and if so is it still the case? GraalVM and TruffleSqueak have evolved quite a bit, but it is still the case. With libgraal, TruffleSqueak warms up much faster, and we were able to further improved the performance of TruffleSqueak. If you'd like to give it a try, it should be fairly easy to get started: https://github.com/hpi-swa/trufflesqueak#getting-started > And more generally, in comparison to the OpenSmalltalkVM, what are the TruffleSqueak downsides? The upsides seem nicely obvious! Tr

Yes, you can load recent, 64-bit, stock Squeak or Cuis images. Pharo is not (yet) supported. The user interface should be identical. For the polyglot API to work, some additional image-side code [1] needs to be loaded in your image. [1] https://github.com/hpi-swa/trufflesqueak/tree/image

You can use TruffleSqueak for all languages supported by the GraalVM. Check out the demo videos at https://github.com/hpi-swa/trufflesqueak#demos.

Not having used them myself, I can't comment on the quality of the JVM based Smalltalks: http://www.redline.st/ https://github.com/hpi-swa/trufflesqueak Another project that I watched without trying myself was for .NET: https://refactory.com/sharp-smalltalk/ There was also Essence# but it doesn't seem active.
