[Xtext 2.0 / Xtend2] Missing methods in API [message #684527]

Hi,

I am using the generated Xtend generator class (implements IGenerator). This uses an JavaIOFileSystemAccess class for actual generation of files. The JavaIOFileSystemAccess has a method to set the output path, that I use.
Later in the generation I want to retrieve the output path from the JavaIOFileSystemAccess object, but there is no getter for the output path. I need this to find out whether files already exist and add special handling for that.

Is there a way to get the output path from the JavaIOFileSystemAccess, or do I need to put an enhancement request in?

Jos

Concerning this issue: how can you modify the default behavior of the
generator so that it uses a different target folder? I mean the
behavior of the generation that is triggered automatically when you save
a file of your DSL (and it uses the src-gen by default).

thanks in advance
Lorenzo

You can either add an enhancement request or you could add a binding to
IFileSystemAccess, i.e. use your own implementation.

Note that within Eclipse a different implmentation is used, which uses
Eclipse's file system API.

You'll have ot override
org.eclipse.xtext.builder.JavaProjectBasedBuilderParticipant or use your
own builder participant.
