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.

func (Command) String added in v0.16.0 

func (c Command) String() string

type DebuggingArgs 

type DebuggingArgs struct {
	// Optional: the address (including port) for the debug server to listen on.
	// If not provided, the debug server will bind to "localhost:0", and the
	// full debug URL will be contained in the result.
	//
	// If there is more than one gopls instance along the serving path (i.e. you
	// are using a daemon), each gopls instance will attempt to start debugging.
	// If Addr specifies a port, only the daemon will be able to bind to that
	// port, and each intermediate gopls instance will fail to start debugging.
	// For this reason it is recommended not to specify a port (or equivalently,
	// to specify ":0").

	// In the case of one or more gopls instances forwarding the LSP to a daemon,
	// URLs will contain debug addresses for each server in the serving path, in
	// serving order. The daemon debug address will be the last entry in the

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

This interface is used to generate logic for marshaling, unmarshaling, and dispatch, so it 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'. For example:

    Command: Capitalized verb phrase with no period

type TestCase added in v0.17.0 

type TestCase struct {
	// Name is the complete name of the test (Test, Benchmark, Example, or Fuzz)
	// or the subtest as it appears in the output of go test -json.
	// The server may attempt to infer names of subtests by static
	// analysis; if so, it should aim to simulate the actual computed
	// name of the test, including any disambiguating suffix such as "#01".
	// To run only this test, clients need to compute the -run, -bench, -fuzz
	// flag values by first splitting the Name with "/" and
	// quoting each element with "^" + regexp.QuoteMeta(Name) + "$".
	// e.g. TestToplevel/Inner.Subtest → -run=^TestToplevel$/^Inner\.Subtest$
	Name string

	// Loc is the filename and range enclosing this test function
	// or the subtest. This is used to place the gutter marker
	// and group tests based on location.
	// For subtests whose test names can be determined statically,
	// this can be either t.Run or the test data table
	// for table-driven setup.
	// Some testing frameworks allow to declare the actual test
	// logic in a different file. For example, one can define
	// a testify test suite in suite_test.go and use it from
	// main_test.go.
	/*
	   -- main_test.go --
	   ...
	   func TestFoo(t *testing.T) {
	       suite.Run(t, new(MyTestSuite))
	   }
	   -- suite_test.go --
	   type MyTestSuite struct {
	   	suite.Suite
	   }
	   func (suite *MyTestSuite) TestBar() { ... }
	*/
	// In this case, the testing framework creates "TestFoo/TestBar"
	// and the corresponding test case belongs to "main_test.go"
	// TestFile. However, the test case has "suite_test.go" as its
	// file location.
	Loc protocol.Location
}

TestCase represents a test case. A test case can be a top-level Test/Fuzz/Benchmark/Example function, as recognized by 'go list' or 'go test -list', or a subtest within a top-level function.

type TestFile struct {
	URI protocol.DocumentURI // a *_test.go file

	// Tests is the list of tests in File, including subtests.
	//
	// The set of subtests is not exhaustive as in general they may be
	// dynamically generated, so it is impossible for static heuristics
	// to enumerate them.
	//
	// Tests are lexically ordered.
	// Since subtest names are prefixed by their top-level test names
	// each top-level test precedes its subtests.
	Tests []TestCase
}

	Root       protocol.DocumentURI // root dir of the view (e.g. containing go.mod or go.work)
	Folder     protocol.DocumentURI // workspace folder associated with the view
	EnvOverlay []string             // environment variable overrides
}
