Functions

func MustParseTime

func MustParseTime(lit string) time.Time

MustParseTime parses a time literal and panics in the case of an error.

func ParseDuration

func ParseDuration(lit string) ([]ast.Duration, error)

ParseDuration will convert a string into components of the duration.

func ParseFile

func ParseFile(f *token.File, src []byte) *ast.File

ParseFile parses Flux source and produces an ast.File.

func ParseRegexp

func ParseRegexp(lit string) (*regexp.Regexp, error)

ParseRegexp converts text surrounded by forward slashes into a regular expression.

func ParseString

ParseTime will parse a time literal from a string.

Types

type Scanner

type Scanner interface {
	// Scan will scan the next token.
	Scan() (pos token.Pos, tok token.Token, lit string)

	// ScanWithRegex will scan the next token and include any regex literals.
	ScanWithRegex() (pos token.Pos, tok token.Token, lit string)

	// ScanStringExpr will scan the next token in a string expression context
	ScanStringExpr() (pos token.Pos, tok token.Token, lit string)

	// File returns the file being processed by the Scanner.
	File() *token.File

	// Unread will unread back to the previous location within the Scanner.
	// This can only be called once so the maximum lookahead is one.
	Unread()
}

Scanner defines the interface for reading a stream of tokens.
