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.

Redline Smalltalk Eclipse plugin

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.
Nice!

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:  http://amber-lang.net
 - 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

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.

Jun for Smalltalk - new release 795

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.

Custom icon themes for Pharo / Eclipse icons

As you may know you can change the UI theme in Pharo.

Just click "System" - "Settings" to open the settings browser and select the user interface in the appearance section. Beside the "Pharo" theme there are also themes called "Vistary" (if you like Windows) or "Watery"/"Watery2" (if you are used to Mac).

You can even implement own themes (as Doru demonstrates with his "White theme").

In the upcoming Pharo 3.0 you can even provide an own custom icon theme.Esteban demonstrates this with this goodie that allows Pharo to look like Eclipse since it uses the same icons as the Eclipse Java IDE.

                   

Click on the screenshot images to zoom. Very useful if you want to show someone fluent in Java the wonderful world of Smalltalk.

Barcodes in Smalltalk

Didnt know Barcodes are so easy to implement in Smalltalk. So I started with EAN13 barcode together with unit tests.

Project lives on: http://smalltalkhub.com/#!/~TorstenBergmann/Barcode

You can also load it using the config browser in Pharo 2.0 now. It is already usable - thanks to the power of Pharo.

Short Guide:

 To instantiate: BarcodeEAN13 value: '2109876543210'
You can get the binarySequence of a barcode:

(BarcodeEAN13 value: '2109876543210') binarySequence

calcuate the checksum (last digit):

 (BarcodeEAN13 value: '2109876543210') computeChecksum

 or visualize the barcode:

  BarcodeEAN13 example asForm asMorph openInWorld

 or to write to a file:

   PNGReadWriter putForm: BarcodeEAN13 example asForm onFileNamed: 'sample.png'

  Now includes EAN8 as well

Units in Smalltalk

I uploaded a "ConfigurationOfUnits" to the MetaRepoForPharo20. With this the "Units" framework is easily loadable from the Pharo 2.0 config browser.

Here are some examples from the Unit framework:

(10km + 10km) gives you 20km

You can also convert easily

  (10km + 24m) as: 1m

gives you  10024 metres.

It is also simple to compare:

  1hour < 10 seconds

which gives you false.

Smalltalk Debugging facilities for web development

A debugger is not only something a developer uses to hunt for bugs. It is also a tool that makes a developer more productive.

In Smalltalk the debugging experience is really impressive. As someone once said:

"I love Smalltalk. I love coding in the debugger, being able to archive processes and restore them exactly later if they encounter exceptions, the amazing reliability. The economy of expression and the brilliant class library."

Soon Amber Smalltalk will bring this debugging experience also to web development. Have a look at this demo video.
