Using model & module dependencies FAQ
// Entry point
// accessing model of the node
model
model = node.
model
;
// "down-"casting it to the interface from MPS open API
SModel sModel = model;
// non-open API interface for MPS model
SModelInternal internalSModel = (SModelInternal) sModel;
// accesing module owning the model
SModule sModule = sModel.getModule();
// Repository or modules
// accessing repository of modules
SRepository sRepository = sModel.getRepository();
// accessing modules from the repository
Iterable<SModule> modules = sRepository.getModules();
SModule module = sRepository.getModule(sModule.getModuleId());
SModule closuresRuntimeModule = sRepository.getModule(
module reference
/closures.runtime/.getModuleId());
// Languages are represented as a special module type
if
(module
instanceof
Language) {
Language language = (Language) module;
}
// Getting language by "direct" reference:
// Note: no repository is mentioned here. In the MPS we actually have single repository now,
// so you can use this expression to get module from the single repository
Language mpsBaseLanguage = (Language)
module
/jetbrains.mps.baseLanguage/;
// Module dependencies
// accessing module dependencies
sequence
<SDependency> dependencies = m
odule.getDeclaredDependencies()
// adding used language to a module
AbstractModule internalModule = (AbstractModule) sModule;
internalModule.getModuleDescriptor().getUsedLanguages().add(
module reference
/jetbrains.mps.baseLanguage/);
// modify module dependencies
sequence
<Dependency> internalDependencies = internalModule.getModuleDescriptor().getDependencies();
sequence
<SModuleReference> usedModuleReferences = internalDependencies.select({~it => it.getModuleRef(); });
internalModule.getModuleDescriptor().getDependencies().add(
new
Dependency(
module reference
/closures.runtime/,
SDependencyScope. DEFAULT , false
));
// working with DevKits:
internalModule.getModuleDescriptor().getUsedDevkits().add(
module reference
/jetbrains.mps.devkit.general-purpose/);
// Models
// accessing models from the module
Iterable<SModel> models = sModule.getModels();
sModule.getModel(sModel.getModelId());
// working with imported models:
internalSModel.importedModels();
internalSModel.addModelImport(sModel.getReference(),
false
);
internalSModel.deleteModelImport(sModel.getReference());
// working with imported languages:
internalSModel.importedLanguages();
internalSModel.addLanguage(mpsBaseLanguage.getModuleReference());
internalSModel.addLanguage(
module reference
/jetbrains.mps.baseLanguage/);
// working with imported DevKits
