With the release of Eclipse 3. With its template based approach, Acceleo can generate code for any kind of languages. These best practices reflect the expertise of Obeo engineers who have developped Acceleo. Generated file name When generating a file, the path of the file should be calculated by a query. Any modification of the generated code will create problems with the traceability information calculated by Acceleo. By using this site, you agree to the Terms of Use and Privacy Policy.
