Regarding Compiler integration with Xtext [message #1784254]

Hello,

I have build a xtext plugin. It is working fine with content assist ,validations and various other custom functionalities. However, I want now this plugin to work with my compiler. Can you please suggest pointer or provide inputs how can I include my compiler to run with existing xtext plugin. I want to compile my program by combining xtext plugin and my compiler. I am looking into the generator class and IXtextBuilder to achieve the same.

Thanks in advance.

Well compiler is very unspecific.
With such a unspecific word builder participant or generator are the right places to look at

Hello Christian,

I am creating an Xtext Builder for my dsl. I have tried various things but was unable to create one.
1. First I override my override Class<? extends IXtextBuilderParticipant> bindIXtextBuilderParticipant() {
return ABSbuilder;
} with my Absbuilder. This is working fine but I need more options such as buildAll,clean and not just an incremental build as provided by IXtextBuilderParticipant. Also, I want not able to attach my custom nature to this builder although the dependency between the builder and nature in present in plugin.xml. Therefore, I tried to override the XtextBuilder.

2. For the Xtext Builder I added the dependency in plugin.xml created a class that extends the Xtend Builder and override @Override
public void configure(Binder binder) {
binder.bind(XtextBuilder.class).to(MyXtextBuilder.class);
} as explained in https://www.eclipse.org/forums/index.php/t/1069946/ but I am also getting registry error. Also, I am not sure where to create this Builder (in geneartor or in ui package).

Please let me know where I am doing wrong.

Thanks in advance.

i dont understand. (1) is called in all cases you describe
see org.eclipse.xtext.builder.BuilderParticipant.build(IBuildContext, IProgressMonitor) (the default impl)

Oh yes I will look into it.... Thank you so much. Just one more question, how can I attach my nature to this builder. Also, this is should be created in geneartor or the ui package?

Builder and builder participant are not the same
So maybe you want to implement your own incremental project builder
( Assuming you don't use any xtext stuff in it)

You can create the nature where ever you want but usually it's done in the UI project

Hello,

Yes they are different, but in Xtext I was not able to implement my custom builder that extends the XtextBuilder. If I try to bind My custom builder by overriding
the e.g. public void configure(Binder binder) {
binder.bind(XtextBuilder.class).to(MyCustomXtextBuilder.class);
} in AbstractxxxxUiModule, I get the registry error ....Guice creation errors. Can we override the build method of XtextBuilder?

still do t get it.

if you want to provide a builder that is not interacting/using xtext then implement a IncrementalProjectBuilder additional to the xtext one.

if you just want to hook into the builderparticipant then bind it

Hi

The Xtext nature and builder provide a variety of services that can be helpful if you use the full range of Xtext's capabilities.

Alternatively the Xtext nature/builder inflicts some unwelcome costs if you do not want these extra capabilities.

It is for you to decide what is appropriate for your application, but I recommend that once you make a positive decision to reject some of Xtext's capabilities, you do so consistently.

If you decide that you do not want the Xtext nature/builder then do not try to use any builder-related Xtext facilities. You are a conventional Eclipse developer who provides their own XXX Nature to invoke their own XXX Builder to do what is appropriate for *.xxx files. As always with Eclipse, copying existing examples is good, but probably the Xtext nature/builder is not a good example. Choose a much simpler example. The find references for extension points in the Manifest Editor is often a good way to find code to copy. (For Photon I have added an OCL nature/builder to fully escape from the Xtext nature/builder.)

NB. As of Photon M6, it is no longer necessary to implement your own Configure->Convert to XXX Project/Unconfigure XXX menu actions; there is a shared platform property page.

Regards

Ed Willink
