Reproducible moldable interactions using Pharo and Bloc

A new inspector model in Pharo that records developer interactions as first-class entities and uses them to reduce repetition: this is part of "Reproducible moldable interactions" master thesis. You can directly jump to the PDF here. Note that the solution presented is implemented in Pharo using Bloc UI infrastructure.

Using P3 to connect Pharo to CockroachDB

One can now also use the P3 driver (PostgreSQL driver protocol 3.0) from Sven to connect Pharo also to CockroachDB. CockroachDB is an open-sourced software project (relational database management system) that is designed to store copies of data in multiple locations in order to deliver requested data when needed. It is described as a scalable, consistently-replicated, transactional datastore. The database is scalable in that a single instance can be run from a laptop while building an app, then scaled to thousands of commodity servers as a business grows.

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-sentry v0.2.2 releases

The unofficial Pharo SDK for Sentry error tracking platform from Peter is available with a new 0.2.2. release. Now with support for breadcrumbs and basic context.

Code is here:  https://github.com/peteruhnak/pharo-sentry

Feenk work on a Diagrammer for Pharo in Bloc

The Feenk team is working on on Diagrammer in Pharo. The idea is that developers should not have to leave the IDE - not even for drawing diagrams and they give a nice graphic preview on a more elaborate control of lines and figures in this tool with some screenshots on their twitter account.

 - Preview 1
 - Preview 2
 - Preview 3

This nicely shows what is already possible in Bloc.

Clean and modular stateful traits for Pharo

Pharo 7 now integrated (beside many others) a special pull request (PR) to integrate a new version of Traits, this version includes the following features:

- Stateful Traits
- Modular implementation, it is loaded after bootstrap
- Cleaner interface
- Reducing duplicate methods as Traits extends from Class

Since Pharo also has Traits, Slots, MetaLinks, ClassAnnotations and other meta facilities it is a very nice lively system to also work on the metalevel and do metaprogramming.

Shortcuts in Settings tool

With the latest version of Commander and the new Calypso Code Browser, all shortcuts are
explorable and configurable.

SQLite Loadable Extensions for Pharo

Pierce implemented SQLite Loadable Extensions and you can find it in the UDBC repository.

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.

Jump in - the water is fine!
