Overview ¶
Package parser implements a parser for Flux source files. Input is provided by a string and output is an abstract-syntax tree (AST) representing the Flux source.
The parser accepts a larger language than is syntactically permitted and will embed any errors from parsing the source into the AST itself.

Functions ¶
func MustParseTime ¶
func MustParseTime(lit string) *ast.DateTimeLiteral
MustParseTime parses a time literal and panics in the case of an error.
func ParseDir ¶
ParseDir parses all files ending in '.flux' within the specified directory. All discovered packages are returned. The parsed packages may contain errors, use ast.Check to check for errors.
func ParseDuration ¶
func ParseDuration(lit string) (*ast.DurationLiteral, error)
ParseDuration will convert a string into an DurationLiteral.
func ParseFile ¶
ParseFile parses the specified path as a Flux source file. The parsed file may contain errors, use ast.Check to check for errors.
func ParseSignedDuration ¶
func ParseSignedDuration(lit string) (*ast.DurationLiteral, error)
ParseSignedDuration will convert a string into a possibly negative DurationLiteral.
func ParseSource ¶
ParseSource parses the string as Flux source code. The parsed package may contain errors, use ast.Check to check for errors.
func ParseString ¶
func ParseString(lit string) (*ast.StringLiteral, error)
ParseString removes quotes and unescapes the string literal.
