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 `flag:"remote" help:"*EXPERIMENTAL* - forward all commands to a remote lsp"`

	// Enable verbose logging
	Verbose bool `flag:"v" help:"Verbose output"`

	// Control ocagent export of telemetry
	OCAgent string `flag:"ocagent" help:"The address of the ocagent, or off"`
	// 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) *Application

Returns a new Application ready to run.

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 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 `flag:"listen" help:"address on which to listen for remote connections"`
	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"`
	// 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.

func (*Serve) DetailedHelp

func (s *Serve) DetailedHelp(f *flag.FlagSet)

func (*Serve) Name

func (s *Serve) Name() string

func (*Serve) Run

func (s *Serve) Run(ctx context.Context, args ...string) error

Run configures a server based on the flags, and then runs it. It blocks until the server shuts down.

func (*Serve) ShortHelp

func (s *Serve) ShortHelp() string

func (*Serve) Usage

func (s *Serve) Usage() string
