Functions

func DisableLog

func DisableLog()

func EnableLog

func EnableLog()

func ExprString

func ExprString(expr ast.Expr) (name string)

ExprString generates code by ast.Expr like printer.Fprint() 经过拼装，可能与源码不完全一致 TODO 2019.9.28 最开始不知道有 printer 这个包，手写了一坨，后面可能会直接接过去。。 Deprecated

func Find

func Find(parent ast.Node, queries []interface{}) (children []ast.Node, err error)

Find returns a slice of sub-nodes like jQuery

func Name

func Name(node ast.Node) string

func ReadPackage

func ReadPackage(pkgPath string) (pkg *ast.Package, err error)

ReadPackage is simple wrapper for parserDir use pkgName with last segment in pkgPath

func ReadPackageWithName

func ReadPackageWithName(pkgPath string, pkgName string, fileScope string, filter func(os.FileInfo) bool) (pkg *ast.Package, err error)

ReadPackageWithName read package with specified package name fileScope used for cache key

func SetLogOutput

func SetLogOutput(writer io.Writer)

func SrcOf

func SrcOf(node ast.Node) string

SrcOf print ast.Node to a string

Types

	io.Writer
}

func (*Writer) SetOutput

func (w *Writer) SetOutput(writer io.Writer)

func (*Writer) Write

func (w *Writer) Write(p []byte) (n int, err error)
