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...

GeoSphere in Pharo

A project to compute distances, parse coordinates, etc. using Pharo.

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.

Dynamic creation of compiler plugins in Pharo

A new class (merged this week into Pharo 7) called "OCCompilerDynamicASTPlugin" allows for the dynamic creation of compiler plugins

Object compiler
 addPlugin: 
  (OCCompilerDynamicASTPlugin 
   newFromTransformBlock: [ :ast | (RBParseTreeRewriter replaceLiteral: 42 with: 'meaning of life') executeTree: ast. ast. ]
   andPriority: 0
  );
 evaluate: '42'.

This would give 'meaning of life'

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

ARCOS - Augmented Reality Collabroative Operating System

Several times within this blog I reported about Croquet. It was written in Squeak Smalltalk and supported communication, collaboration, resource sharing, and synchronous computation among multiple users. Basically it was a followup of ideas from Morphic - but all in 3D. You could create and visit portals to interactively collaborate.


 If I remember correctly it was later open sourced and ended up in OpenCobalt.NET - there are still some infos are on the Squeak wiki and a video on Youtube.



 It was also continued as OpenQwaq platform and used to form solutions for a company named 3dicc
(started by Ron Teitelbaum, David A Smith and Andreas Raab).

I also reported on the Lively Kernel project - a JavaScript based Kernel and IDE to also followup on these ideas allowing dynamic and linked worlds within your web browser. There is also a video available.

Now it seems there is a fully new web based implementation of these historic ideas available. It is called ARCOS - Augmented Reality Collabroative Operating System and if you check it out you will find many similarities.

Fully written in JavaScript and based on LivelyKernel but with a similar UI as in Squeak Croquet. If you check out the source code you will even find that the classes are prefixed with a "T" - which was back in the time the prefix for TeaTime (a specific framework for Croquet).

You can try it instantly in your browser using the following link or watch the following videos for a demo:

Caffeine.js and WebVR - Smalltalk in 3D

git-migration and Tonel for Pharo

If you want to migrate projects from SmalltalkHub (or any MCZ-based repo) to GitHub to profit from new git integration in Pharo then use Peters "git-migration" tool.

The tool is now using the Tonel format to store the code. Tonel is a file-per-class format, that means a class and all methods are stored in a single file. This is faster than having a file for each method but also prevents some trouble with git on Windows due to number of files and subdirectory depth.

Iceberg 0.7 explained

Iceberg - the Code Versioning Tool for Pharo with a binding to git now has a reworked model and UI. Esteban gave an intro to it in a techtalk:


 

GraphQL

REST services are easy to implement in Pharo - especially with "Teapot" and my simple "Tealight" extensions for it. Read the Tealight project page with some documentation and examples to get an idea about it.

If you worked with or heard about REST then you might also come across GraphQL. It's a technology initially developed at Facebook.

In GraphQL, the shape of the response is built up on the server side to match the shape of a given JSON query.

So while in REST when you ask for a "book" item you receive a predefined JSON response with all attributes of the book. In GraphQL you might ask only for the books title or in another case for the books title and author at the same URL and receive an appropriate response.

Now there is also an initial library for GraphQL available for Pharo and VisualWorks.

Really nice!

Pharo 7 time planning

Usually we have a Pharo release each year in May - but the Pharo 7 release is now defered to the end of the year for good reasons.

The switch to git took a lot of time and is still ongoing with a rework in progress for Iceberg tool to simplify the UI. Also the 64 virtual machine for Windows and other important tasks keep Esteban busy. Additionally new additions to the Pharo ecosystem like the new Calypso system browser need to be integrated.

Which gives more time for contributions and cleanups. Meanwhile there are nice changes merge already (like the Shift class builder, latest Iceberg, many cleanups, ...) there are also nice additions in the pipe like the possibility to extend the Playground similar to Inspector or the possibility to use the foreign function interface without the source file in a deployment scenario.


Here is a description for the new contribution process. As an alternative you can also use my contribution project with scripts and a help topic to get you started easily. You can also use the new Pharo Launcher 1.1. or Fari - a shell to fetch and prepare new images. There will also be a Google summer of code (GSOC) in 2018 for the 14th year.

There are also additional sprint dates already announced till June 2018.
