Autocomplete suggestion files in project [message #1831521]

Hey,

I have question - at certain points in editor I want to suggest:
1. JSONPaths from other file
2. file names that are in user project

I was able to set up simple grammar and generator, language server that Theia is using.

Somehow files are ending up in src-gen in user project anyways :)

So now in .ide module in IdeContentProposalProvider I want to get list of files that are in user's workspace (or in src-gen in user's workspace)
Additionally I want user to provide sample JSON or XML from which I can get all JSONPaths or XMLPaths and add some proposal as well.

In generator I have IFileSystemAccess2 that allows me to access user files, but I cannot inject same object into IdeContentProposalProvider. Is there any way to do this?

After some digging I am able to create IFilesSystemAccess2, but for that to work correctly I need actually filepath of currently edited file. Is there any way to obtain it from - my guess would be something from ContentAssistContext?

i assume you have to hook into the workspace creation / updates and build up and index of arbitray files yourself.
see org.eclipse.xtext.ide.server.LanguageServerImpl.initialize(InitializeParams) respectively

org.eclipse.xtext.ide.server.WorkspaceManager.initialize(List<WorkspaceFolder>, Procedure2<? super URI, ? super Iterable<Issue>>, CancelIndicator)
org.eclipse.xtext.ide.server.WorkspaceManager.refreshWorkspaceConfig(CancelIndicator)
