SQLite3 for Pharo updated and moved

In the past PierceNG and me were maintaining SQLite3 driver for Pharo. As in 2019 another Pharo community member (Julien Delplanque) contributed to the project it was better to align and move the project to a more community owned location.

So SQLite3 for Pharo was reworked to be fully standalone and it was moved to community owned "pharo-rdbms" location:

  https://github.com/pharo-rdbms/Pharo-SQLite3

Additional Docu and CI support was added with green builds for Pharo 6.1, Pharo 7 and Pharo 8.

The old locations were marked deprecated.

ReStore for Pharo

ReStore - an object relational database framework originally available for Dolphin Smalltalk was ported to Pharo.

Nice - I should give it a try.

Pharo XML support packages moved to GitHub

In November 2019 some time was spend to move the XML Support for Pharo from old SmalltalkHub to a community managed location on GitHub:

     https://github.com/pharo-contributions

For the detailed packages this means

• BitmapCharacterSet moved to GitHub
• XMLWriter moved to GitHub
• OrderPreservingDictionary was updated to 1.5.0
• XMLParser moved to GitHub
• XMLParserHTML moved to GitHub
• XMLParserStAX moved to GitHub
• XPath moved to GitHub
• Pastell moved to GitHub

Fortunately there is a nice tool from Peter Uhnak called "git-migration" that helped a lot in this transition and preserved original commit history as much as possible. 

Additionally some more cleanups were applied and a continuous integration (CI) was established.

The move to GitHub should help to better maintain contributions to these projects and also verify that the XML support runs on newer Pharo versions.

Pharo Bootstrapping Challenges

In the beginning of the year 2019 I already wrote that Pharo is able to bootstrap the image. This is based on the Pharo Bootstrap project from Guille and already used in the Pharo Bootstrap process itself to form images like Pharo 7 and Pharo 8 for the releases.

If you look in the Pharo project repository you will find a bootstrap folder with the code that is used to bootstrap the standard pharo image if you are interested.

But sometimes you want to build and bootstrap an own fully custom image. There are new tools helping you to do this like the nice Pharo Bootstrapper project. This project allows you to use Pharo build small images and bootstrap own Smalltalk systems if you like.

I can also recommend to read the paper: "Challenges in Debugging Bootstraps of ReflectiveKernels"

Pharo Headless - Beta

An early preview - but you can already get real headless vm and image from zero-conf and play with it. This is work from the Pharo Consortium Team from the last couple of months.

Some interesting features:

• Image handles creation of main world - so the Pharo world instantiation and handling is even more shifted to the image side - allows to play with new ideas on world and window creation This will provide more backends: the regular VM support (compatibility with non-headless VMs), and OSWindow with two additional backends: SDL and GTK3+ (implemented using UFFI calls)
• Handling of events on the image side - which will hopefull allow for better event handling as we can process events directly within the image and not the VM
• VMMaker code migrated to Tonel and update on VMMaker to execute in Pharo 7 and 8 - this allows for easier VM building of the Pharo virtual machine (which is based on OpenSmalltalk VM)
• Removing GPL code from the VM repository - to be more license clean

And the one I like most: the virtual machine is now a dynamic library. Which is the first but an important step towards embedding Pharo into other applications!

If you want to try it out check the headless branch within the OpenSmalltalk VM repository:

https://github.com/pharo-project/opensmalltalk-vm

There is also a Continuous integration (CI) job available.

Pharo bindings to the LLVM disassembler and Unicorn library

Guille Polito wrote bindings to the LLVM disassembler and Pharo bindings to the Unicorn library. Both projects are available on GitHub:

https://github.com/guillep/pharo-llvmDisassembler
https://github.com/guillep/pharo-unicorn

This should allow for better machine code simulation directly within Pharo.

 

Spec2

The UI framework in Pharo receives an update. Spec2 will replace Spec over time - it is already included within upcoming Pharo 8 (which is still in development). Both run in parallel to ease migration.

Source code is also on GitHub: https://github.com/pharo-spec/Spec

It is possible to load Spec2 into latest Pharo release - Pharo 7. You will find a script on the project page. Some early documentation on Spec2 is already available as PDF booklet - but as the framework itself work in progress.

Spec2 will also allow for a binding to other backends like Gtk (which is based on Mars project from Esteban):

https://github.com/pharo-spec/mars-gtk

Pharo Compiler: add the concept of a Production Environment

In Pharo so far the Compiler compiled into instances of class CompiledMethod. Now, there might be the case that the result of the compiler (the compiledMethod) should not be an instance of the class CompiledMethod from the environment in which we compile, but from some other environment.

The Pharo compiler is now able to support that as Marcus explains here.

This is more flexible and should allow for cross compiling locally or into remote environments. One could use it to build up a new environment within the existing one, ...

Nice!

Telemon: Pharo and TIG

Pharo and native UIs - from Mars to Spec

Pharo 7 (beside many other features) was focused on being able to bootstrap an image right from the source as well as the transition to using git. Also stabilizing Iceberg tool with Git binding to have an improved source code management and give Pharo and its source code more exposure to the outside non-Smalltalk world.


Now Pharo 8 (which is currently in development) will focus on an updated version of Spec called "Spec 2.0". To build abstractions and prove that other backends (beside Morphic) could be used there is a plan to have a GTK binding as a second backend. This goes back to the old "Mars" project from Esteban - a native user interface framework which aimed to bring the native UI into Pharo. If I remember correctly back at the time it used an ObjectiveC Bridge.

This was already discussed on PharoDays 2019 and now Esteban gives some more detailed infos about the background on the Pharo mailinglist.

Workflow engine written in Pharo

Debugger driven development in Pharo

ComputedSlots in Pharo

In Pharo 8 it is now possible to use ComputedSlots. Beside the regular instance variable (slots) we add a computed slot with a block.

Let's assume I would like to implement a Person class with a name and firstName but also get a fullName.

Object subclass: #Person
 slots: { #name. #firstName. #fullName => ComputedSlot with: [ :obj | obj firstName asString , ' ' , obj name asString ] }
 classVariables: {  }
 package: 'Simple-Example'

so when you test

 
|p|
p := Person new.
p name: 'Adams'.
p firstName: 'Douglas'.
p fullName 
 

it would return the full name 'Douglas Adams'.

When you now add an additional class side method #firstName:name: like

firstName: firstName lastName: lastName

 ^(self new)
  firstName: firstName;
  name: lastName;
  yourself

you can simply write with our small english like DSL:

 (Person firstName: 'Douglas' lastName: 'Adams') fullName

to get the same result.

For sure we could have implement the getter method #fullName like this:

fullName

 ^self firstName asString , ' ' , self name asString

to achieve the same - but a computed slot shows up really in the inspector as if it would be a real variable and is recomputed if you for instance would change the name or firstName.

Pharo 7.0 released

Smalltalk systems influenced computing like no other technology in the world. You will find many of its ideas in all modern software systems ranging from graphical user interfaces up to mobile devices.

With Pharo-Project we continue with this tradition to provide an inspiring lively object-oriented system but also move Smalltalks ideas to the next level.

Today is the day we release Pharo 7.0 into the wild and again as a free open source gift to the world.

This is yet another major step towards a brighter future for dynamic development approaches. Pharo 7.0 was realized by a worldwide community of 75 people - taking us over one year of distributed development.

Pharo advanced on many sides. Now we can fully bootstrap into a custom image - including Slots, Metalinks and other meta facilities. New books and tutorials were written about it, it is used in web development, IoT and other. It's already a business driver for several companies worldwide with a growing number of users.

2142 issues solved in general - 762 commits done from my side (astares) alone. Mostly trivial stuff but each still important to cleanup and form a well structured core. Dont know if I could be proud to have climbed to the top in github contribution statistics in this release - personally I will remember the PR's primary as 762 times fighting with the CI infrastructure ;)

Pharo 8 work already started now ... so come in - the water is just fine. Step by step it goes...

Maizo and Pharo

Maizo - a Chemistry project developed with Pharo.

To quote research gate:

Maizo is aimed toward molecular- and reaction discovery based on big data of quantum mechanical global reaction route mappings. The global reaction data includes equilibrium structures (EQs), dissociation channels (DCs), and transition structures (TSs), which are automatically calculated by a global search on a potential energy surface using the GRRM (global reaction route mapping) method. Applications to molecular- and synthesis design are an important part of the project. Machine learning and visualization techniques as well as chemoinformatics methods are essential to acquire useful information from the large reaction data space. The team developed an RMapViewer, which was developed to visualize and analyze the GRRM outputs.

Exploring Pharo

There is a nice blog post about his initial experience with Pharo from Konrad Hinsen. He overall likes Pharo and especially the explorability but also has two primary points to criticize:

1. he mentions that Pharo is not reproducible and can not be bootstrapped from its own source code 
2. it is not easy for beginners to follow Pharo
   

The first point is actually invalid. Konrad seem to have missed that Pharo since two years IS ACTUALLY  BOOTSTRAPPED - so we can build a image from scratch and from our own source code. This is actualy in place and used to build Pharo now. Even smaller images (like the minimal one) beside what is provided in the default Pharo download.

People interested in this topic should read this blog post from 2014 and check the "bootstrap" folder in the Pharo github project. This is based on the PharoBootstrap work. Someone interested in this topic might also be interested in this video.

For the second point I agree as Pharo is moving fast it might not be easy to follow. Also the community is small. Due to this we can not invest our sparce resources into making things easy for newbees - but rather will continue to focus on moving forward. Especially with the upcoming Pharo 7 including better git support and the new Calypso browser many things have changed compared to Pharo 6.

But there are books available and there is the mailinglists as well as the Discord chat to ask questions and get answers. Situation is far better than in 1994 when I dived into Smalltalk and where it was not easy to get informations or even a free system to enjoy the openess and productivity of such a system.

Nonetheless - as one of the primary contributors of the Pharo project I really enjoy such blog posts. It shows we are on the right track. There is still a long way to go - but step by step it goes...

How to use Extensions in Pharo

In Pharo it was always possible for a package to extend a class within another Package. So far it was done by putting a * in front of the method name.

In Pharo 7 this changes a little bit as you can directly select the extension from the new Calypso system browser.

Here is a description about the differences.

Parser performance in Smalltalk

Some insights into Parser performance in Smalltalk

Pharo totally bootstraps

Rather unnoticed but is now finally working:

Pharo images are now build from NOTHING. Not a single byte of image exists before: During build process, a very small image is first bootstrapped using a technique developed by Guille Polito during his PhD. Then the rest of the packages are loaded in a regular way.

This is how Pharo 7 (which is intended to be released around November) is now built!

Truly object oriented test

How to find out if a system is truly object oriented. In this old video Dan Ingalls explains how you can simply test this.

In Smalltalk systems like Squeak and Pharo you can do it.

GotalkInterpreter

I like Go as a programming language. It is open source, has a funny mascot and supports easy creation of executables. Still it is not the same as working with a nice Smalltalk system like Pharo.

I guess others see it the same way. That's why a simplistic Smalltalk code interpreter written in Golang is available here: https://github.com/SealNTibbers/GotalkInterpreter

To quote: Why Smalltalk Smalltalk is beautiful dynamic language with a concise and readable syntax. Also we are smalltalkers so that's why.

Stylesheet for Pharo

When writing stylesheets (CSS) for the web it is not recommended to hard code the colors in each stylesheet rule - because often it is a tedious task to adopt or change them afterwards.

Therefore often people use CSS preprocessors like LESS or SaaS or Stylus where you can define variables or other to ease the job.

If you already work in Pharo you might want to easily write your stylesheets in Smalltalk. Thats the idea behind "Stylesheet" - a project to define CSS like stylesheet in Pharo applications.

The project was now migrated from SmalltalkHub to GitHub and can be found on: https://github.com/pharo-contributions/Stylesheet
