Functions

func Annotate

func Annotate(name string, mode string, varVar string, importpathFilename string, globalCoverVarImportPath string) string

QINIU Annotate do following 1. add cover variables into the original file 2. return the cover variables declarations as plain string original dec: func annotate(name string) {

Types

type Block

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

Block represents the information about a basic block to be recorded in the analysis. Note: Our definition of basic block is based on control structures; we don't break apart && and ||. We could but it doesn't seem important enough to bother.

type Buffer

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

A Buffer is a queue of edits to apply to a given byte slice.

func NewBuffer

func NewBuffer(data []byte) *Buffer

NewBuffer returns a new buffer to accumulate changes to an initial data slice. The returned buffer maintains a reference to the data, so the caller must ensure the data is not modified until after the Buffer is done being used.

func (*Buffer) Bytes

func (b *Buffer) Bytes() []byte

Bytes returns a new byte slice containing the original data with the queued edits applied.

func (*Buffer) Delete

func (b *Buffer) Delete(start, end int)

func (*Buffer) Insert

func (b *Buffer) Insert(pos int, new string)

func (*Buffer) Replace

func (b *Buffer) Replace(start, end int, new string)

func (*Buffer) String

func (b *Buffer) String() string

String returns a string containing the original data with the queued edits applied.

type File

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

File is a wrapper for the state of a file used in the parser. The basic parse tree walker is a method of this type.

func (*File) Visit

func (f *File) Visit(node ast.Node) ast.Visitor

Visit implements the ast.Visitor interface.
