func (*Commands) Call

func (c *Commands) Call(cmdstr string, t *Term) error

Call takes a command to execute.

func (*Commands) CallWithContext

func (c *Commands) CallWithContext(cmdstr string, t *Term, ctx callContext) error

CallWithContext takes a command and a context that command should be executed in.

func (*Commands) Find

func (c *Commands) Find(cmdstr string, prefix cmdPrefix) command

Find will look up the command function for the given command input. If it cannot find the command it will default to noCmdAvailable(). If the command is an empty string it will replay the last command.

func (*Commands) Merge

func (c *Commands) Merge(allAliases map[string][]string)

Merge takes aliases defined in the config struct and merges them with the default aliases.

func (*Commands) Register

func (c *Commands) Register(cmdstr string, cf cmdfunc, helpMsg string)

Register custom commands. Expects cf to be a func of type cmdfunc, returning only an error.

func (*Commands) WriteMarkdown

func (commands *Commands) WriteMarkdown(w io.Writer)

type ExitRequestError

type ExitRequestError struct{}

func (ExitRequestError) Error

func (ere ExitRequestError) Error() string

type Term

type Term struct {
	InitFile string
	// contains filtered or unexported fields
}

Term represents the terminal running dlv.

func New

func New(client service.Client, conf *config.Config) *Term

New returns a new Term.

func (*Term) Close

func (t *Term) Close()

Close returns the terminal to its previous mode.

func (*Term) RedirectTo

func (t *Term) RedirectTo(w io.Writer)

RedirectTo redirects the output of this terminal to the specified writer.
