Help System for Pharo/Squeak

Some months ago I wrote a help system for Pharo and Squeak
to provide an easy way to browse available documentation
for the open source Smalltalk systems.

You can use it to display available API documentation
(extracted from class/method comments) and to provide custom
documentation in form of simple written text books.
These informations are extracted from the image by two
predefined help builder classes that convert the help contents
to instances of "HelpTopic".
These HelpTopics can be nested (book structure) and displayed
in a HelpBrowser. Since help text is extracted/stored in
classes and methods you can use the usual tools to maintain
and package help contents together with your code.

The design is simple but nonetheless powerfull since by
allowing you to integrate own custom help builder classes
you can easily integrate documentation extracted from any
source available to you.

It was accepted by the community and integrated in both
standard images (Pharo 1.1/Squeak 4.1). Thanks guys!

Laurent now created a new screencast to show you how to use
it:

http://pharocasts.blogspot.com/2010/09/document-with-helpsystem.html

Starting from now, no excuses not to write documentation ;)

It is still ASCII based but I have plans to integrate other media
types (especially HTML) in the near future...

Instantiations bought by Google

Instantiations was acquired by Google - mainly to get the Eclipse, Java expertise. Interesting enough the company now continues with its VA Smalltalk business:

"The new Instantiations will focus entirely on Smalltalk and remains fully committed to supporting and evolving the products we all know and love!"

The Wave is closed

Google Wave is closed. I think there was too much of a hype than usable technology. Read the announcement.

BTW: The announcement was written by Urs Hölzle who formerly worked at Animorphic systems (yes, the company that had one of the fastest Smalltalk JIT's and that was later acquired by Sun).

There is now also a nice app called "TextLint" which is written in Pharo Smalltalk. It is a lint tool for common style errors in natural language. You can use it to process your text/latex/... files.

Here are videos (1 and 2)showing the tool in action.

Pharo 1.1. Setup for Windows

The new Pharo 1.1 release comes (similar to the first version) as a large download: the one-click image with virtual machines for all major platforms (Windows, Mac, Linux).

As before for those who want to use/run Pharo 1.1. on Win32 system only I additionally prepared a smaller installer for the new release. Read more. As ever it is also available on the Pharo project site.

Sunset or Eclipse with Oracle JVM

When you run the new Oracle JVM 6u21 and Eclipse you may encounter frequent Eclipse crashes.

Eclipse launcher (which is written in C/C++) reads the JVM vendor and if it detects a Sun JVM, it adds a necessary memory parameter for Eclipse to function.
Since now the "Java" vendor was changed from Sun to Oracle it crashes.

So the current version of Eclipse does not work with the current version of Java on the most popular platform - at least not out of the box.

There is a bug report already ...

Smallthought Systems bought by Twitter

The Smallthought Systems company which is known for dabbledb.com (an online data tool written in Smalltalk using Seaside) was acquired by Twitter today.

Interesting, looks like dabbledb.com service continues but does not allow new registrations and Avi (who is also the creator of the original Seaside framework) is now working for Twitter in the Twitter's analytics team. Either he will now switch to Ruby again or we can expect Twitter services driven by Smalltalk in the future. Who knows ...

Interesting. Should we play more golf to promote Smalltalk? Why not - a golf course is often the place where business decisions are made ... ;)

Squeak and Pharo Installer for Windows

There are different ways to get Smalltalk installed on your machine.

Pharo by default provides a one click image (30MB) which is useful if you want to work with different platforms. It's a simple ZIP file.

I additionally prepared a Windows installer which is only 10MB and more aligned with what a Windows user expects. You can try Pharo 1.0 with it here.

Meanwhile Ian has picked up my script for Squeak and it is nice to see one can also easily install Squeak 4.1. with it now too.

Apple removes Scratch from iPhone

The discussion on the license change for Apple continues.
Meanwhile Scratch (which is written in Squeak Smalltalk)
was also removed.

Apple tries to keep complete control - I'm sure this wont work. Especially since there are alternatives like Android which offers more freedom.

Pharo 1.0 released

We finally made it ... Pharo 1.0 is released.

Just go and download it.

Future of Java

Oracle bought Sun, now they provide Sun server hardware and also "own" Java (and other technologies like MySQL, JavaFX, ...). I know that there is a JCP, but I think the driving force behind Java development is now Oracle.

Interesting that James Gosling (inventor of Java) now left Oracle.

Interesting times ...

The Moose Book

If you want to do software and data analysis then you should read the

about the Moose technology. Moose is an analysis platform written in Smalltalk.

The (yet unfinished) book already includes descriptions on how to use Moose, how to build a browser with Glamour or how to load the latest Moose version into Pharo using Metacello.

One interesting aspect (beside a good documentation on Moose) is that this is now the second dynamic web book on Smalltalk technologies (after the Seaside online book) which is written using the Smalltalk based Pier Content Management System.
