	// contains filtered or unexported fields
}

Env captures all the state needed to run gql commands. Thread compatible

func New

func New(sess *gql.Session, interactive bool) *Env

Loop runs an interactive eval loop. It never retuns.

func (*Env) NewOutput

func (c *Env) NewOutput() termutil.Printer

NewOutput creates a Printer object that prints to the standard output.

func (*Env) PrintValue

func (c *Env) PrintValue(ctx context.Context, val gql.Value, mode gql.PrintMode, out termutil.Printer)

PrintValue prints the given value to the terminal with paging.
