Acceleo 3.0 is a pragmatic implementation of the OMG Model-to-text specification. It supports the developer with most of the features that can be expected from a top quality code generator IDE: simple syntax, efficient code generation, advanced tooling, features on par with the JDT ... Acceleo also has a unique tooling around example-based design of code generators.
The Acceleo Project (previously named MTL) is an open source component under the Eclipse Modelling / Model To Text
(M2T) project . Its primary goal is to provide an implementation of the MOF Model To Text OMG
You do not need to be an expert to start using the plug-ins:
using the provided example projects and the powerful completion
feature of the Acceleo editor, it is very easy to get started once you
understand the basic principles.
If you don't know anything about Acceleo, you can start with a little demo
Acceleo at Eclipse Modeling Runaway 2010
Concerning the language, almost all of the OMG specification keywords are supported
(those marked with an asterisk are not fully supported yet):
module, import, extends, template, query, public, private, protected, guard, init,
overrides, each, before, after, for, if, elseif, else, let, elselet, trace*, macro*,
file, mode, text_explicit*, code_explicit*, super, stdout
For all the details about these keywords and the MOF Model to Text Language in
general, you can consult the official MTL Specification available at the OMG website.
Note that a documentation is also available in the Acceleo plugins.
From Acceleo.org to Eclipse.org
Acceleo.org was created 4 years ago, and as the time goes, the Team has been more and more convinced that the MOF Model To Text OMG specification was the way to go for the project. We started to code a reference implementation for the standard within the Eclipse M2T project. We have managed to provide nice tooling, simple syntax and efficient code generation with all the pragmatism we had about Acceleo.org. There aren't a lot of differences between the old version of acceleo and the new one.
We are confident that the Acceleo community gain value from moving to a self hosted project to an Eclipse one, and that end users will follow the transfert from Acceleo.org to Eclipse.org as we will provide the same level of functionnalities and we will insure an interoperability between the old syntax and the new syntax (the standard one).
The Acceleo Team will continue to maintain the old syntax of Acceleo outside of eclipse (www.acceleo.org ) during some few years, but the new versions and the new features will take place on Eclipse.org. In the next release you'll have an automated tooling helping you to migrate your templates from a syntax to another.
For Acceleo lover, you will find in Eclipse Acceleo everything you have loved in the Acceleo.org version and more (the standard compliance with more documentation).
This specification is really a good one : http://www.omg.org/spec/MOFM2T/1.0
For Helios, this is the first time we plan to graduate under Eclipse. We also plan to grow the version number from 0.9.0 to 3.0.0 because
the last release of Acceleo outside of Eclipse was the 2.7.0 version (Acceleo.org). We are also in the process of transferring the community,
and for a community point of view, it is clearer to graduate and set the new Eclipse version as 3.0.0.
