Roassal 3d progressing

Building and deploying your first web app with Pharo

Sven wrote a nice tutorial on how to build and deploy your first Pharo webapplication. It does not use any of the known Smalltalk webframeworks (like Seaside, Aida, Iliad, ...) - it requires only the Zinc HTTP components that are already part of the Pharo image.

He also explains how to deploy the final result to the cloud.


Chapter on Blocks

The "Deep into Pharo" book now also contains a chapter about Blocks. Download is here.

Redline Smalltalk Eclipse plugin

The Eclipse plugin for Redline Smalltalk moves forward as this screenshot proves.


Athens on Amber

Athens - the Smalltalk graphic framework that is now also part of upcoming Pharo 3.0 is also available for Amber Smalltalk.

So you can write your graphics code in Pharo first and run it later in Amber directly within a webbrowser.
A demo is here. You have to move the splitter in the middle of the helios IDE to see the "do it" button.

Hopefully Amber and Pharo will continue to stay as much as possible compatible - then you can freely choose the appropriate platform for writing server side (Pharo or Amber on node.js), rich client (Pharo) or webbrowser (Amber) code in Smalltalk.

Playing with Helios in new Amber

Now that the new Amber 0.11.0 is released I'm sure you want to play with Smalltalk and the new Helios IDE of Amber in your webbrowser. For those who need some instruction:

 - open the Amber homepage:
 - press F12 in your Google chrome browser to get the debgging tools, now click on the Javascript console
 - evaluate "amber.loadHelios()" and press enter - now Helios is being loaded
- when loading is finished press CTRL + Space to open the Helios IDE

You can open Browser, TestRunner, Workspace and play with it.



Gradualtalk is a gradually-typed Smalltalk, which is fully compatible with existing Smalltalk code. Image is based on Pharo Smalltalk and the type system is deactivated by default. 


Amber 0.11.0 released

Amber Smalltalk 0.11.0 released with more fixes, more commiters, more tests, ....
This release includes also the Helios IDE (which is not yet the default but can be opened via JavaScript).

You can either download it or install it via NPM (the node.js package manager).

SourceCity for Pharo with CI job

SourceCity is a 3D visualization tool for analyse object-oriented systems. There is a new Jenkins CI job to build a "SourceCity" image right from the metacello config.

So you just need to download the image and run with the usual Pharo VM. To create a visualization just evaluate:

            SourceCity exampleRpackage

Note that SourceCity is meanwhile open source with MIT license. Code can be found on SmalltalkHub.
Read more about the project here (page is a little bit slow) or here.


Roassal with Sunburst visualization

There is also some progress on a Sunburst visualization for Roassal. Click the image to zoom the screenshot:



Roassal with 3D support

New class builder in Pharo 3.0

The latest updates of Pharo 3.0 contain a new class builder. Check out

  PharoClassInstaller example

 for an example.

 This will end up in the support of "slots" - a slot is a meta-object for accessing a field in an Object. This makes class building also more explicit - for instance you can define the layout when building a class (PointerLayout, ByteLayout, ...)

So instead of having an instanceVariables array you can now have real layout objects. The implementation also includes field modifications which can track changes required to migrated instances (adding/removing fields, shifting position, ...).

Read more about Slots here.
