[ANN] Improving dialect portability and git support

Very nice, Mariano!

----------

I do think it would be nice to have the dynamic {} array syntax supported. It definitely increases readability, even if it does add gratuitous syntax. The scanner and parser are relatively easy to modify. If you want, I can send you an example which I created to support parsing VisualWorks literal references: #{[name.]*name} e.g. #{Kernel.UserMessage}

Here at Instantiations we are helping to improve dialect portability by implementing some frameworks that are gaining acceptance in the greater Smalltalk community.

Closely related to this is a new feature we are working on that will bring VA Smalltalk support for text-based version control systems like Git. 

We wanted to take this opportunity to make public Pharo2VA [1], a little tool to ease exporting code from Pharo to VA Smalltalk.

This tool does a few things, one being the auto-conversion of the curly brackets Array.

Pharo2VA is installed and run in Pharo in order to facilitate the later import in VA. If you check at the top of the GitHub project you can see some labels about the current release, the CI status (made with Travis CI), and the results of Coveralls (test coverage). This is part of the things that could come when you can use GitHub for managing your code. 

Tonel [2] is a file-per-class text-based export/import format for Smalltalk code. Tonel works well on Windows and Linux filesystems, files are readable and it is Git-friendly (actually any kind of text-based versioning control system).

STON [3], short for Smalltalk Object Notation, is a lightweight, text-based human-readable data interchange format for class-based object-oriented languages like Smalltalk. It can be used to serialise domain level objects, either for persistency or network transport. By offering class tags for objects as well as support for object references, arbitrary object graphs can we written and read back. Tonel uses STON to encode the definitions metadata. 

We have STON currently working in 9.2 and Tonel already in progress and we expect to finish both by the next release. The availability of these projects in VAST will not just allow for storing VA Smalltalk code in version control systems like Git (something our customers have begun asking about), but it will also store it in a community format to facilitate sharing code across the various dialects in the Smalltalk community.

As a preview, we have created this repository [4] where you can find some demo apps that were exported from VA in Tonel format and they could also be imported into other

dialects such as Pharo, Gemstone, VW or any other dialect supporting Tonel format.

We also wanted to thank all the people that participated in the definition or implementation of all these projects.
