Acceleo overview

You have landed on 2.x maintenance stream website.

The last version is now available on the Eclipse website.

Integration within eclipse

Acceleo is natively integrated with eclipse. It is completely merged with its interface for better efficiency and user experience.

Acceleo provides many features for template editing : completion

  • syntax highligthing
  • meta-model and scripts based completion
  • real time error detection
  • real time preview

Development cycle management


Aiming at 100% code generation is not always the most efficient choice. Hand-coding is often faster and more maintainable than modeling.
Acceleo deals with incremental generation, by defining specific coding zones with user tags. These zones are conserved when generating again.

Acceleo offers an appropriate solution to avoid the extremist policy "Everything has to be specified within the model". We prefer "Use tools for what they are best for".

Additionaly, we deliver Acceleo with an integrated chain generation system. Project generation chainings is very easy and quickly customized.

Ability to cope with high level abstract models


Given a simple modelled class, it becomes easy to generate several files, such as XML files, Java classes, web service descriptors... We name this "asymetric generation".
With Acceleo you can embed architecture concepts and patterns in your modules and then guarantee best development practices are used automatically and consistently.

A model is not any more a contemplative artefact, but a real added value abstraction used in a productive way.

Example : You have to model a business object implemented as an EJB. Would you rather :

  1. Model only one business class ?
  2. Model all necessary classes (Home, Remote, Local, Bean...) for the EJB implementation ?
The first solution is clearly more efficient. Models are more understandable, independent of any technology and easier to maintain.

Furthermore, you don't need to add element decoration to your models, Acceleo is powerful enough to keep purely functional models. Implementation intelligence is embedded in Acceleo modules and not in models.

Efficient syntax

Acceleo syntax is designed to guarantee full visibility on the technical generated implementation.
It is the result of many years of experience with template generation technologies and provides peerless efficiency, maintainability and ability to evolve for modules.



Acceleo is based on the main industry standards to guarantee high level compatibility, interoperability and durability.
Acceleo is especially compatible with XMI 1.x and XMI 2, ensuring compatiblity with the main UML modelers on the market (RSM, Together, Poseidon, ...).

uml Acceleo was designed to work with any meta-model, implementing MOF and QVT recommandations as specified by the OMG.
So new UML versions or even any other meta-model can be instantly used with Acceleo.
In addition, Acceleo is independent from the targetted technology. You may generate Java, XML, documentation or any other textual format (C, VB, Cobol.....).
