gopls/v0.19.1

This patch release changes the default value of the importsSource setting: v0.19.0 changed it from goimports to gopls; this release changes it back, due to a bug (#74280).

Configuration Changes

• The gopls check subcommand now accepts a -severity flag to set a minimum severity for the diagnostics it reports. By default, the minimum severity is "warning", so gopls check may report fewer diagnostics than before. Set -severity=hint to reproduce the previous behavior.

Navigation features

"Implementations" supports signature types (within same package)

The Implementations query reports the correspondence between abstract and concrete types and their methods based on their method sets. Now, it also reports the correspondence between function types, dynamic function calls, and function definitions, based on their signatures.

To use it, invoke an Implementations query on the func token of the definition of a named function, named method, or function literal. Gopls reports the set of function signature types that abstract this function, and the set of dynamic calls through values of such types.

Conversely, an Implementations query on the func token of a signature type, or on the ( paren of a dynamic function call, reports the set of concrete functions that the signature abstracts or that the call dispatches to.

Since a type may be both a function type and a named type with methods (for example, http.HandlerFunc), it may participate in both kinds of Implements queries (method-sets and function signatures). Queries using method-sets should be invoked on the type or method name, and queries using signatures should be invoked on a func or ( token.

Only the local (same-package) algorithm is currently supported. (https://go.dev/issue/56572 tracks the global algorithm.)

"Go to Implementation" reports interface-to-interface relations

The "Go to Implementation" operation now reports relationships between interfaces. Gopls now uses the concreteness of the query type to determine whether a query is "downwards" (from an interface to the types that implement it) or "upwards" (from a concrete type to the interfaces to which it may be assigned). So, for example:

• implementation(io.Reader) subinterfaces such as io.ReadCloser, and concrete implementations such as *os.File.

• implementation(os.File) includes only interfaces, such as io.Reader and io.ReadCloser.

To request an "upwards" query starting from an interface, for example to find the superinterfaces of io.ReadCloser, use the Type Hierarchy feature described below. (See microsoft/language-server-protocol#2037.)

Support for Type Hierarchy

Gopls now implements the three LSP methods related to the Type Hierarchy viewer: textDocument/prepareTypeHierarchy, typeHierarchy/supertypes, typeHierarchy/subtypes.
