Programmatically read language version
Hi,
I have the requirement to generate a comment into each class that tells which language version was used for modelling.
Is there a way (via smodel language, for example), to access the language version? I am referring to this number:

Okay, i found this in OpenAPI: language/my.dsl/.getLanguageVersion(), but is marked deprecated.
@Deprecated //normally, one shouldn't have used it. If you had, switch to getting version from LanguageRuntime
can someone explain to me what is meant by this comment? I do not know how to get the "LanguageRuntime"
I have the same problem to understand what was meant by this comment.
Supposed the stub jetbrains.mps.smodel@java_stub is imported,
you should be able to safely cast the source module to jetbrains.mps.smodel.Language:
((Language) language/my.dsl/.getSourceModule()).getLanguageVersion();
which is a short hand version for
((Language) language/my.dsl/.getSourceModule()).getLanguageDescriptor().getLanguageVersion();
The module version is also available from here:
((Language) language/my.dsl/.getSourceModule()).getLanguageDescriptor().getModuleVersion();
LanguageRuntime is the abstract class, which will be extended to implement the abstract method int getVersion().
In the source_gen folder of your language you will find a class named Language extending LanguageRuntime.
There are the generated hard coded values from the LanguageDescriptor along with some other stuff. But you will possibly miss the module version.
