Xtext 2.3 Nature and Builder Issues [message #938990]

Hi,

I hope someone can help me with this. My knowledge of Xtext is not excellant so please bare with me.

I have a question regarding Xtext natures, builders and marker creation.

Eclipse Version: Indigo
Xtext Version: 2.3
Xtext Project size: 100+ files

I have migrated my software from xtext 0.7 to 2.3 and when using xtext 0.7 I did not have to add an Xtext nature to the project and the xtext FAST checks were only triggered when an xtext editor was opened and the NORMAL checks were run when the file was saved. Both checks created problems view markers. After upgrading to xtext 2.3 the checks are only visible in the editor and no problems view markers are created for the FAST and NORMAL checks.

1) For xtext 2.3 do I "now" have to apply an Xtext nature to the whole project? I assume this is the case becuase without doing so no markers are created? I applied the xtext nature to the project and now the markers are created.

2) Is it possible to apply an xtext nature to an editor only when it is opened rather than applying the nature to the whole project so it will work the same as when I was using xtext 0.7.

3) From what I have read apparently xtext has changed so that the builder now creates the markers and the builder is initialised automatically when a nature is added. The issue I have with this is that all xtext fast and normal checks are run on all xtext editors when the project is created and becuase I have 100+ editors project creation takes longer.

Thanks in advance for your help.....

Best Regards

Sam

Hi Sam,

A nature can only be set on project level. It is stored in the .project file. Thus it is not possible to activate it only for an editor.

The Xtext builder checks projects for having the Xtext nature. Other projects are ignored from building.

Why do you have 100+ editors open at once? This barely makes sense to me. Or do you just mean that you have 100+ files in the project? Of course checking them takes some time, but this is only evaluated when resources change. I guess you mean you are creating a project and thus resources in the project, so naturally these resources need to be checked when the project is built.

Kind regards,
~Karsten

Nature is always for the entire project. IIRC, if the nature is not on
when an editor is opened on a file, xtext asks if the nature should be
turned on.

Hi Karsten,

Thanks for your reply.

Sorry for the confusion. Yes I just mean I have 100+ files in my project so I am creating a project and resources in the project.

Usually a user will only need to open and update 1 of the files but they may wish to open up a few other files for reference. Due to the fact a user will only be viewing a few of the files I only want the xtext checks to run on those particular files and not the entire project.

Do you think this is possible?

Thanks

Sam
