How to use

If there is an update to the LSP specification, navigate to the protocol directory and run go generate. This will generate all the types needed for the analyzer. You need to add ExtendedClientCapilities map[string]interface{} json:"extendedClientCapabilities"`` to XInitializeParams struct. Other than that, you should be good to go.

Changes

• Created extensions.go
  • Need to implement Supports method fully.
• Commented out writeclient() and writeserver() in generate/main.go
• Commented out "Or_WorkspaceFoldersServerCapabilities_changeNotifications": "string", in generate/tables.go
• Changed type DocumentURI string to type DocumentURI = string in generate/output.go
• Need to add ExtendedClientCapilities map[string]interface{} json:"extendedClientCapabilities"`` to XInitializeParams struct. Need to figure out why needed. Can remove if not.
