Types

type File

type File struct {
	Funcs    map[string]*ast.Func
	Tests    []*ast.Test
	Imports  map[string]string
	Comments []*ast.Comment
	Tokens   []lexer.Token
}

File contains the output state of the parser for a single input.

func (*File) Pos

func (file *File) Pos(offset int) string

Pos returns the rendered position of a token.

type Parser

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

func ParseString

func ParseString(s string, fileName string) *Parser

ParseString parses source code and returns the AST for the file.

func (*Parser) AppendError

func (p *Parser) AppendError(node ast.Node, message string)

AppendError adds an error to the stack.

func (*Parser) AppendErrorAt

func (p *Parser) AppendErrorAt(pos string, message string)

AppendError adds an error to the stack.

func (*Parser) AppendErrorf

func (p *Parser) AppendErrorf(node ast.Node, format string, args ...interface{})

AppendErrorf adds an error to the stack.

func (*Parser) AppendFinally

func (p *Parser) AppendFinally(finally *ast.Finally)

AppendFinally will track finalizers until the function is finished, then it will be reset.

func (*Parser) Errors

func (p *Parser) Errors() []error

Errors returns all errors.
