Functions

func Parse

func Parse(input string, parse func(*parser) interface{}) (result interface{}, errors []error)

Parse creates a lexer to scan the given input string, and uses the given `parse` function to parse tokens into a result.

It can be composed with different parse functions to parse the input string into different results. See "ParseExpression", "ParseStatements" as examples.

func ParseDeclarations

func ParseDeclarations(input string) (declarations []ast.Declaration, errors []error)

func ParseExpression

func ParseExpression(input string) (expression ast.Expression, errors []error)

func ParseProgram

func ParseProgram(input string) (program *ast.Program, err error)

func ParseProgramFromFile

func ParseProgramFromFile(filename string) (program *ast.Program, code string, err error)

func ParseStatements

func ParseStatements(input string) (statements []ast.Statement, errors []error)

func ParseType
