Dear Pharo users and dynamic language lovers:
We have released Pharo <https://pharo.org/> version 12!
What is Pharo?
Pharo is a pure object-oriented programming language and a powerful
environment focused on simplicity and immediate feedback.
* Simple & powerful language: No constructors, no types declaration,
no interfaces, no primitive types. Yet a powerful and elegant
language with a full syntax fitting in one postcard! Pharo is
objects and messages all the way down.
* Live, immersive environment: Immediate feedback at any moment of
your development: Developing, testing, debugging. Even in production
environments, you will never be stuck in compiling and deploying
steps again!
* Amazing debugging experience: Pharo environment includes a debugger
unlike anything you've seen before. It allows you to step through
code, restart the execution of methods, create methods on the fly,
and much more!
* Pharo is yours: Pharo is made by an incredible community, with more
than 100 contributors for the last revision of the platform and
hundreds of people constantly contributing with frameworks and
libraries.
* Fully open-source: Pharo full stack is released under MIT
<https://opensource.org/licenses/MIT> License and available on
GitHub <https://github.com/pharo-project/pharo>
... more on the Pharo Features page <http://www.pharo.org/features>.
In this iteration of Pharo, we continue working on our objectives of
improvement, clean-up and modularization. Also, we included a number of
usability and speed improvements. A complete list of changes and
improvements is available in our Changelog
<https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo120ChangeLogs.md>
Some highlights of this amazing version:
Highlights
New breakpoint system
The debug point system is a breakpoint model that supersedes the
previous implementation of breakpoints and watchpoints. They are
configurable, composable, and extensible. The traditional breakpoints
remain available, including conditional breakpoints, one-time
breakpoints, and object-centric breakpoints. Additionally, there are new
types of breakpoints, such as chained-breakpoints, which condition the
activation of certain breakpoints on the triggering of others (e.g.,
breakpoint B only activates if breakpoint A is hit first). Debug points
also feature a dedicated browser and integration options.
Tools
* Scalable fluid class syntax is now the default one
* Preparing the introduction of the Bloc graphic system by migrating
more tools to Spec2 widgets
* Spec2 UI framework enhancements to support GTK 4
* Leaner version of the Metacello package manager
* More robust and strict mode for FFI
System
* New architecture for refactorings and domain specific transformations
* Code loading speed improvement
* Fast browsing via fully optimized package tags
* Optmized memory usage via optimized method protocols
* Compiler simplifications and improvements
Virtual machine
* Massive image support with permanent space
* String/ByteArray comparison speed up
