Types

type Pos

type Pos int

Pos is the position in a string. Negative numbers indicate undefined positions.

type PositionRange

type PositionRange struct {
	Start Pos
	End   Pos
}

PositionRange describes a position in the input string of the parser.

func (PositionRange) StartPosInput

func (p PositionRange) StartPosInput(query string, lineOffset int) string

StartPosInput uses the query string to convert the PositionRange into a line:col string, indicating when this is not possible if the query is empty or the position is invalid. When this is used to convert ParseErr to a string, lineOffset is an additional line offset to be added, and is only used inside unit tests.
