How do I set the package for my generated Java files? [message #1168050] Sun, 03 November 2013 03:17 Go to next message

I'm guessing that it is a setting in the GenerateSpinCAD.mwe2 file, however I'm pretty reluctant to change things without knowing what I'm doing. I just recovered from a couple days digression based on trying to change the package definition via refactoring in Eclipse. Won't try that again! Embarrassed

I want my generated Java files to be part of this package:

package com.holycityaudio.SpinCAD.CADBlocks;

(which code is inserted into the Java source file).

However they are being generated in the /SpinCADBuilder/src-gen/(default package) package.

What do I need to do?

Thanks,

GW

Hi,

it is actually derived from the grammar name

grammar org.xtext.example.mydsl2.MyDsl

leads to package

org.xtext.example.mydsl2

Hmmm I'm a bit confused.

In my 1st instance of Eclipse, all the generated code that parses the grammar is located in packages that I defined in my grammar file. That part of it is fine.

Now I launch my second instance of Eclipse, and I created some new files of the type which my grammar is supposed to parse. When I save one of these files, the translated version (a Java file) is created. How do I set the package where THAT file gets created?

As it stands now, I am keeping my Xtext grammar and Xtend code generator (Eclipse instance #1) in a different package/path than the source code for my actual Java application (Eclipse instance #2). The application uses a combination of hand written Java code and the classes which are generated using my grammar.

Hi,

do you mean the stuff you generate in your IGenerator or Inferred by JvmModelInferrer?
in both cases your are the one to blame. if you do not give the file a path (IGenerator)
or a QualifiedName (Inferrer) you may not complain if there is no package

Certainly I am to blame! LOL.

Anyway it is the IGenerator. So I guess what I have to do is determine the path (with slashes) of the desired package and then prepend that to the name of the desired generated file. What I had done previously was to use a "fully qualified name" prefix (with dots) and it simply added that to the file name of each generated file, but still put them in the (default package).

I'll give it a try. Thanks for the hint.

[Update] - got it working. Thanks again.

GW
