Why don't you simply post process files with gnat pretty after
generation?

A few comments, but you should go on the Acceleo web site for this:

> [for (p : Parameter | o.eAllContents(Parameter))]

This is highly un-optimized: you are looping over all elements
contained in an uml::Operation and checking for each of them if their
metatype is a (subtype of) uml::Parameter. What you really want to do
is:

[for (p : Paramenter | o.ownedParameter)]

that is, using the UML metamodel as a sort of grammar. The same
applies for looping over operations from a Class (ownedOperation) and
so on

Also note that Acceleo has a separator facility to separate the
printing of the elements of a sequence with a string but on the last
position (useful to print the ";" after all parameters but the last
one).
