MemFS

This extension implements an in-memory file system to show-case the filesystem provider api. It serves two purposes:

• Be a sample/reference for extension authors that want to implement a filesystem provider
• Be a test for other extensions that falsely assume text document always live on disk.

To get started you need this:

• install this extension
• when not having a workspace opened, select 'F1 > [MemFS] Setup Workspace' (optionally save the workspace now)
• select 'F1 > [MemFs] Create Files' and notice how the explorer is now populated
• ... try things out, e.g. IntelliSense in memfs-files, create new files, save them, etc
• open file.txt and make changes
• 'F1 > [MemFS] Delete "file.txt', observe that the editor is now indicating that the file is deleted
• 'F1 > [MemFS] Add "file.txt', observe that the editor content is reset and the '(delete)' annotation disappeared
• select 'F1 > [MemFs] Delete Files' or reload to restart
