Hi

I started to migrate my DSL to Xtext 2.3 milestone; in the compiler
methods I see that now Xbase requires an ITreeAppendable instead of
IAppendable... since I was using StringBuilderBasedAppendable (which
does not implement ITreeAppendable), what class should I use now? would
the class TreeAppendable be OK?

thanks in advance
Lore

Hi Lorenzo,

what do you want to do? The appendable is created by the framework and
passed to clients.

Sebastian

Hi Sebastian

in this DSL I'm not using the inferrer (for the moment) and I have a
custom xbase compiler which I call from the generator, thus I have to
create the appendable myself...

Is FakeTreeAppendable the right substitute?

thanks in advance
Lorenzo

Hi Lorenzo,

yes you can use that but you won't get debugging for free.
TreeAppendable is the actual implementation, but it imposes some
constraints on how you use the compiler. If you don't need the tracing
and jsr45 stuff, FakeTreeAppendable is the way to go.

Regards,
Sebastian

Dear All,

I need your favor or suggestion regarding migrate the xtext version from 1.0.1 to 2.3.0 in custom application.

I followed all following process for migrate the xtext version.
1. Delete the old plug-ins and update the latest plug-ins in target platform.
2. Update the Plug-in Dependencies and Import Statements.
3. Introduction of the Qualified Name.
4. Changes in the index and in find references.
5. Rewritten Node Model.
6. AutoEditStrategy.
7. Other Noteworthy API Changes
To consider the above steps, I started the work with Eclipse-4.2, Which has a xtext-2.3.0 dependency. Successfully I completed the all above steps and removed the compilation error.

Problem: After that I start the testing and getting below error Messages:
[XtextLinkingDiagnostic: null:6 Couldn't resolve reference to Material 'MPS_RECUR'.,
XtextLinkingDiagnostic: null:9 Couldn't resolve reference to Cstic 'NUM_OF_ALLOC'.,
XtextLinkingDiagnostic: null:15 Couldn't resolve reference to Cstic 'INSTANCE_NUM'.,
XtextLinkingDiagnostic: null:14 Couldn't resolve reference to Class 'ALLOC'.]
