SqueakJS JavaScript bridge

Didnt notice (until today) that SqueakJS has a JavaScript bridge allowing you to call JavaScript from Squeak running in your browser. Nice!

BTW: when it does not work when you visit the page first time, then just reload the page. Bert already has a bug for this.

Dolphin Smalltalk 7

Dolphin Smalltalk is a nice Smalltalk System for Windows. Version 7 will be available today and it will be fully open source with MIT license on GitHub. Read more.

The sources for both the image and the virtual machine will be available.

For those who do not know it:
Dolphin is a Smalltalk system for Windows provided by Andy Bower and Blaire McGlashan from www.object-arts.com. The article from BitwiseMag gives an overview.

The existing Dolphin 6.2 codebase was brought by Andy Bower now under Git and compiles completely under VisualStudio Community 2013. This is a new version, Dolphin 7, that is modelled off the previous X6.1 Professional Edition (although you can choose to build Dolphin Community Edition from it if you like).

It is simplified implementation of text tools which operate on single text instance

The case of Pharo and Moose

The 8th ACM SIGPLAN International Conference on Software Language Engineering was held in Pittsburg during 25-27 October 2015.

There was a keynote from Stéphane Ducasse entitled: "What's the value of an end user? Platforms and Research: The case of Pharo and Moose".

It summarizes a little bit what has been achieved so far with Pharo, although it does not include all the community efforts. Here are the 171 slides

Want to work with Pharo? Noury Bouraqadi is looking for a PhD student to work on multi-robot exploration and mapping.

Smalltalk vs JavaScript

Richard Eng continues his Smalltalk series with "Smalltalk vs JavaScript".

In my opinion even when JavaScript is not optimal it is highly dynamic as well and a lot can be done with it. It might become the next assembly layer to stay portable (WebAssembly, asm.js and EmScripten can be used as target). We all know that the web grows and there are more devices where you can run on with JS out of the box. And yes: Amber and PharoJS are interesting projects for this as well.

For sure emulation/virtualization technology will increase in the future: you can already boot Linux in a browser, even with network support. You can also run a whole Smalltalk environment in your browser like with SqueakJS or Amber.

New Scratch version for Raspberry Pi

There's a new version of Scratch for Raspberry Pi: it's faster, and has built-in GPIO support and access to the camera module. Examples are available to help you get started with easy projects using LEDs, sensors and motors, and a beginners' tutorial is on the way. I guess Scratch is the most widely distributed Smalltalk app (written in Squeak Smalltalk)

Pharo and OpenMP

Looks like Pharo's NativeBoost works great with OpenMP. Read more.

Smalltel

Pharo 5 now fully includes Opal Compiler - the old one will be removed. This allows for many nice extensions.

 For instance Ronie Salgado has a small package called "Smalltel" - the name is an abbreviation for Smalltalk string template language. The package provides a class SmalltelCompiler as a subclass OpalCompiler.

There is also a class SmalltelObject overriding the method #compilerClass to return the new compiler class. With the custom compiler one can provide templates with expressions in Smalltalk, a little bit similar to what Java has with Expression Language (EL):




condition: cond value: value
 ^ ByteString streamContents:
<[Here goes a header:
 ${ cond ifTrue: [ }$
  Conditional value: $( value printString )$
 ${ ]. }$
]>

Roundtrip

When I use Eclipse and Java I still like the nice eUML2 AddOn Tools as they allow to define quickly a conceptual model in UML. It's also the only tool I've found for Java that is able to support roundtrip engineering and that allows you to keep close to the code while still doing modeling.

DynaCase for Pharo looks promising but such roundtrip tools are still missing in the Pharo tools universe.

Unified IDE

Lots of new editors for JavaScript appear - Atom, Brackets, ... and now Nuclide.

The web page of the last one tells us that Nuclide is a "A unified IDE". Hey - wake up! It is just a fancy editor - nothing more and I really wonder if these guys have ever see a real unified IDE with browsers, refactoring tools, test runner etc.

NeoConsole

Sven provides a nice demo that shows how to use his new project NeoConsole, a command line (REPL) interface, to interact with and control a running, headless Pharo image.

The video also shows how to start from scratch, downloading Pharo, installing NeoConsole, running a headless image with the REPL installed in the background. Next, an HTTP server is added to the image and later a specific response is added as well.

Short summary: Pharo is well suited for maintaining cloud and web based applications as it allows live interaction even after deploying.

The application is written in Seaside on top of Pharo and is hosted on PharoCloud.

NanoStrand - Pharo Smalltalk bindings for nanomsg

nanomsg is a simple, fast socket abstraction library that supports many communication patterns ("scalability protocols").

NanoStrand is a gate to the nanomsg world for Smalltalk users. Since there are many language-bindings for nanomsg, integrations with other network programs would be much simpler via NanoStrand.

The project page includes a nice description on how to use it in Pharo, there is also a presentation available.
