Import workspace as Dependency

[kapishsingla]

Hi Team,

I am trying to import a workspace containing my Langium-based DSL documents (demo.lang) from project_A as a dependency into my current project_B. My expectation is that when project_B is loaded, it should automatically build project_A as part of the process.

From what I understand, I can use the WorkspaceManager.initializeWorkspace() method and provide the paths for both project_A and project_B while loading project_B.

To provide a clearer analogy, this process is similar to importing a Maven project in the pom.xml file, allowing us to use the classes from the imported project.

Could you please guide me on how to proceed with this implementation? Additionally, is my understanding of how to load and integrate different projects correct?

Hi @kapishsingla,

I think that by default all dsl files from the workspace are built and you can have cross references between them.

You can override the DefaultScopeProvider:getGlobalScope by providing a list of visible URI is you want to restrict visibility on some files.

langium/packages/langium/src/references/scope-provider.ts

Line 101 in d11ab3a

return this.globalScopeCache.get(referenceType, () => new MapScope(this.indexManager.allElements(referenceType)));

In this case you have to implement your own logic to retrieve the visible URIs from a given document.

edit: There is no concept of project in VSCode. If you want this concept you have to implement your own logic in a separate DSL or in a configuration file.
