Functions

func BoolConst

func BoolConst(j *lint.Job, expr ast.Expr) bool

func CallName

func CallName(call *ssa.CallCommon) string

func CallNameAST

func CallNameAST(j *lint.Job, call *ast.CallExpr) string

func Dereference

func Dereference(T types.Type) types.Type

Dereference returns a pointer's element type; otherwise it returns T.

func DereferenceR

func DereferenceR(T types.Type) types.Type

DereferenceR returns a pointer's element type; otherwise it returns T. If the element type is itself a pointer, DereferenceR will be applied recursively.

func ExprToInt

func ExprToInt(j *lint.Job, expr ast.Expr) (int64, bool)

func ExprToString

func ExprToString(j *lint.Job, expr ast.Expr) (string, bool)

func FilterDebug

func FilterDebug(instr []ssa.Instruction) []ssa.Instruction

func GroupSpecs

func GroupSpecs(j *lint.Job, specs []ast.Spec) [][]ast.Spec

func Inspect

func Inspect(node ast.Node, fn func(node ast.Node) bool)

func IsBlank

func IsBlank(id ast.Expr) bool

isBlank returns whether id is the blank identifier "_". If id == nil, the answer is false.
