Overview

Package command defines the interface provided by gopls for the workspace/executeCommand LSP request.

This interface is fully specified by the Interface type, provided it conforms to the restrictions outlined in its doc string.

Bindings for server-side command dispatch and client-side serialization are also provided by this package, via code generation.

Interface defines the interface gopls exposes for the workspace/executeCommand request.

This interface is used to generate marshaling/unmarshaling code, dispatch, and documentation, and so has some additional restrictions:

  1. All method arguments must be JSON serializable.
  2. Methods must return either error or (T, error), where T is a JSON serializable type.
  3. The first line of the doc string is special. Everything after the colon is considered the command 'Title'. TODO(rFindley): reconsider this -- Title may be unnecessary.
