Support for Dynamic Content Roots

[iamrecursion]

Summary

In addition to the basic project content root, we want the language server to have support for dynamically added content roots.

Value

The IDE will be able to let users add arbitrary folders to their project.

Specification

• Add support for multiple content roots in the language server.
• Implement the following messages as specified in the design document.
  • file/addRoot - Allows adding of a new content root. This will create a lot of file/event messages to inform clients of the now-visible files and folders.
  • file/removeRoot - Allows removing a content root. This will create a lot of file/event messages to inform clients of the now-gone files and folders.
  • file/rootAdded - Sent to all clients other than the one adding the root.
  • file/rootRemoved - Sent to all clients other than the one removing the root.
• Update file/event to support dynamic content roots.

Acceptance Criteria & Test Cases

• The above specification has been implemented.
• The language server can now support dynamic content roots.
