Functions

func ParseFile

func ParseFile(file *source.File, src []byte, trace io.Writer) (res *ast.File, err error)

ParseFile parses a file with a given src.

func ParseSource

func ParseSource(src []byte, trace io.Writer) (res *ast.File, err error)

ParseSource parses source code 'src' and builds an AST.

Types

type Error

type Error struct {
	Pos source.FilePos
	Msg string
}

Error represents a parser error.

func (Error) Error

func (e Error) Error() string

type ErrorList

type ErrorList []*Error

ErrorList is a collection of parser errors.

func (*ErrorList) Add

func (p *ErrorList) Add(pos source.FilePos, msg string)

Add adds a new parser error to the collection.

func (ErrorList) Err

func (p ErrorList) Err() error

Err returns an error.

func (ErrorList) Error

func (p ErrorList) Error() string

func (ErrorList) Len

func (p ErrorList) Len() int

Len returns the number of elements in the collection.

func (ErrorList) Less

func (p ErrorList) Less(i, j int) bool

func (ErrorList) Sort

func (p ErrorList) Sort()

Sort sorts the collection.

func (ErrorList) Swap

func (p ErrorList) Swap(i, j int)

type Parser

type Parser struct {
	// contains filtered or unexported fields
}

Parser parses the Tengo source files.

func NewParser

func NewParser(file *source.File, src []byte, trace io.Writer) *Parser

NewParser creates a Parser.

func (*Parser) ParseFile

func (p *Parser) ParseFile() (*ast.File, error)

ParseFile parses the source and returns an AST file unit.
