Constants

const (
	SemanticLeft  = "/*⇐"
	SemanticRight = "/*⇒"
)

prefixes for semantic token comments

Variables

var ErrInvalidRenamePosition = errors.New("request is not valid at the given position")

ErrInvalidRenamePosition is returned when prepareRename is run at a position that is not a candidate for renaming.

Functions

func CloseTestConnections

func CloseTestConnections(ctx context.Context)

CloseTestConnections terminates shared connections used in command tests. It should only be called from tests.

Types

type Application

type Application struct {

	// Embed the basic profiling flags supported by the tool package
	tool.Profile

	// We include the server configuration directly for now, so the flags work
	// even without the verb.
	// TODO: Remove this when we stop allowing the serve verb by default.
	Serve Serve

	// Support for remote LSP server.
	Remote string `` /* 344-byte string literal not displayed */

	// Verbose enables verbose logging.
	Verbose bool `flag:"v,verbose" help:"verbose output"`

	// VeryVerbose enables a higher level of verbosity in logging output.
	VeryVerbose bool `flag:"vv,veryverbose" help:"very verbose output"`

	// Control ocagent export of telemetry
	OCAgent string `flag:"ocagent" help:"the address of the ocagent (e.g. http://localhost:55678), or off"`

	// PrepareOptions is called to update the options when a new view is built.
	// It is primarily to allow the behavior of gopls to be modified by hooks.
	PrepareOptions func(*source.Options)
	// contains filtered or unexported fields
}

Application is the main application as passed to tool.Main It handles the main command line parsing and dispatch to the sub commands.

func New

func New(name, wd string, env []string, options func(*source.Options)) *Application

New returns a new Application ready to run.

func (*Application) Commands

func (app *Application) Commands() []tool.Application

Commands returns the set of commands supported by the gopls tool on the command line. The command is specified by the first non flag argument.

func (*Application) DetailedHelp

func (app *Application) DetailedHelp(f *flag.FlagSet)

DetailedHelp implements tool.Application returning the main binary help. This includes the short help for all the sub commands.

func (*Application) Name

func (app *Application) Name() string

Name implements tool.Application returning the binary name.

func (*Application) Run

func (app *Application) Run(ctx context.Context, args ...string) error

Run takes the args after top level flag processing, and invokes the correct sub command as specified by the first argument. If no arguments are passed it will invoke the server sub command, as a temporary measure for compatibility.

func (*Application) ShortHelp

func (app *Application) ShortHelp() string

ShortHelp implements tool.Application returning the main binary help.

func (*Application) Usage

func (app *Application) Usage() string

Usage implements tool.Application returning empty extra argument usage.

type Definition

type Definition struct {
	Span        span.Span `json:"span"`        // span of the definition
	Description string    `json:"description"` // description of the denoted object
}

A Definition is the result of a 'definition' query.

type GoplsStats

type GoplsStats struct {
	GOOS, GOARCH                 string `anon:"ok"`
	GOPLSCACHE                   string
	GoVersion                    string `anon:"ok"`
	GoplsVersion                 string `anon:"ok"`
	InitialWorkspaceLoadDuration string `anon:"ok"` // in time.Duration string form
	CacheDir                     string
	BugReports                   []goplsbug.Bug
	MemStats                     command.MemStatsResult       `anon:"ok"`
	WorkspaceStats               command.WorkspaceStatsResult `anon:"ok"`
	DirStats                     dirStats                     `anon:"ok"`
}

GoplsStats holds information extracted from a gopls session in the current workspace.

Fields that should be printed with the -anon flag should be explicitly marked as `anon:"ok"`. Only fields that cannot refer to user files or code should be marked as such.

type Serve

type Serve struct {
	Logfile     string        `flag:"logfile" help:"filename to log to. if value is \"auto\", then logging to a default output file is enabled"`
	Mode        string        `flag:"mode" help:"no effect"`
	Port        int           `flag:"port" help:"port on which to run gopls for debugging purposes"`
	Address     string        `` /* 181-byte string literal not displayed */
	IdleTimeout time.Duration `` /* 127-byte string literal not displayed */
	Trace       bool          `flag:"rpc.trace" help:"print the full rpc trace in lsp inspector format"`
	Debug       string        `flag:"debug" help:"serve debug information on the supplied address"`

	RemoteListenTimeout time.Duration `flag:"remote.listen.timeout" help:"when used with -remote=auto, the -listen.timeout value used to start the daemon"`
	RemoteDebug         string        `flag:"remote.debug" help:"when used with -remote=auto, the -debug value used to start the daemon"`
	RemoteLogfile       string        `flag:"remote.logfile" help:"when used with -remote=auto, the -logfile value used to start the daemon"`
	// contains filtered or unexported fields
}

Serve is a struct that exposes the configurable parts of the LSP server as flags, in the right form for tool.Main to consume.
