We are happy to announce the release of Spoofax 1.1! This is the first major release since version 1.0.2 and includes major features and improvements. Spoofax 1.1 supports all current Eclipse versions, up to version 4.2.2.
, the Spoofax Name Binding Language.
is used in all new projects created and significantly simplifies name binding analysis, as well as any editor services that depend on it (e.g., code completion, reference resolving)
We have started a Q&A site for Spoofax to build a knowledge base of common questions and answers. Join us at
Today we're releasing a minor maintenance release of Spoofax, version 1.0.2. This release fixes a memory leak that was introduced in the 1.0 release. There are no new features in this release, those will be included in the upcoming 1.1 release instead. The new version is now available from the update site at

Spoofax 1.0
We're pleased to announce the release of Spoofax 1.0. A number of significant new features have been added since the last stable release, a long list of bugs has been fixed, and various minor improvements were introduced.
Highlights of the release include:
The new version is now available from the update site at
http://spoofax.org/update/stable.
In addition to these features, we're actively working on improving Spoofax with new features. In particular, we are now working on providing full support for debugging, on an interactive shell for Stratego and custom languages, and a new meta-language called SpoofaxLang to define languages in a more modular fashion.
A full list of feature requests and issues addressed in the new version is provided at

Introducing the Spoofax Language Workbench
We're pleased to announce the 0.5 release of the
Spoofax language workbench, an Eclipse plugin that seamlessly integrates Java versions of Stratego and SDF into Eclipse. Spoofax can be used to develop new languages and transformations based on SDF and Stratego in the Eclipse environment. Read on below and be sure to follow our
tour with screenshots for more information.
Stratego and SDF for Java
Stratego and SDF have traditonally been implemented using C, but to increase portability we have developed Java versions of the
Stratego compiler and
the JSGLR parser for SDF. These new implementations are seamlessly integrated into the Spoofax environment, but can also be used as stand-alone tools.
Building programming languages with IDE support
IDE support has become essential for developers to be productive with programming languages. Spoofax provides IDE support for Stratego and SDF for developers of languages and transformations. It also aids in the development of IDE support for new languages: from the first version of an SDF grammar, an editor can be created for the language and used
side-by-side with the definition in Eclipse. Using Stratego, the editor can be enhanced with transformations and semantic editor services such as reference resolving and content completion.
The screenshot below illustrates some of the IDE features supported by editors created with Spoofax (click to enlarge):
More information
Spoofax can be downloaded from
spoofax.org or
strategoxt.org/Spoofax. When installed in Eclipse, the plugin provides a "New project" wizard that creates a new skeleton project illustrating some of the Spoofax features. The website also includes a
tour further showcasing the features of the workbench. For migrating C-based Stratego projects to Spoofax, please read our
FAQ or contact us in case of other questions.
An overview of the architecture of Spoofax and how Spoofax can be used in the development of new languages and IDE services is given in the paper
The Spoofax Language Workbench. Rules for Declarative Specification of Languages and IDEs by Lennart Kats and Eelco Visser, accepted for publication at
SPLASH/OOPSLA 2010. Further documentation can be found on the Spoofax website.

Stack traces on "rewriting failed"
Since late March, the Stratego compiler and auxiliary libraries have
supported stack traces upon rewriting failed. The following trace is
taken from a typical
XTC component that uses
io-wrap:
./prog: rewriting failed, trace:
main_0_0
io_wrap_1_0
option_wrap_5_0
lifted144
input_1_0
lifted145
output_1_0
lifted0
my_wrap_1_0
foo_0_0
bar_0_0
zap_0_0

New URLs for Subversion, Releases, and Bug-tracking
All the Stratego/XT development tools have been moved to subdomains of
strategoxt.org. An overview:
Thanks to Eelco Dolstra for doing most of this work!

Global Variables
Stratego now supports
scoped global variables. In the context of a dynamic rules section one
can now write
rules( Foo := <compute> )
which abbreviates the following commonly used programming pattern:
x := <compute>
; rules( Foo : _ -> x )
The value bound in the assignment can be retrieved by the application <Foo>.
The usual scoping features of dynamic rules apply to global variable as well.

blog.

AspectJ-front revived, support for Microsoft Windows
The
AspectJ-front package has been updated to be easier to install and be more portable. The AspectJ syntax definition of AspectJ-front heavily exercises the
SDF parser generator, which used to make it rather difficult to install the package on machines with a limited amount of memory. The new packages includes the compiled parse tables and also the package is more portable, including support for native Microsoft Windows! The package now also provides a library (DLL on Microsoft Windows) for parsing and pretty-printing AspectJ source files.

x86-64 support for Stratego/XT!
Stratego/XT supports x86-64 processors (in 64-bit mode) from release
0.17M3pre16744 (
or later), the sdf2-bundle from release
2.4pre212034 (
or later). The preliminary releases are available from our new
Nix buildfarm at the TU Delft. The x86-64 support is based on a branch of the ATerm library developed by Eelco Dolstra and Erik Scheffers, and some new 64-bit patches for the sdf2-bundle. The x86-64 bit requirements are completely hidden in the ATerm library and the Auto/XT build system, thus packages based on Stratego/XT should support x86-64 machines out of the box if they do not contain custom native C code. The preliminary releases with 64-bit support will soon be used in the Stratego/XT packages
integration build, which currently still refers to the
Nix Buildfarm at Utrecht University. More information about the issues and the specific patches required for x86-64 support is available in a
post at
Subject to Meta Programming.

Stratego/XT Packages Channel
The Stratego/XT packages channel now provides
integration builds for Stratego/XT, its dependencies, and packages based on Stratego/XT. We have created this channel after frequent questions about which packages work together. From now on, this is the way to install the latest developments of Stratego/XT. If you install packages from this channel, then they are guaranteed to work together. If your favorite Stratego/XT package is currently not on the channel, just send us a request. If the package is maintained and in reasonable use, then we will add it to the channel.
