Overview

Package astutil provides shared AST/type helper functions used by linters.

Index

• func IsFmtErrorf(pass *analysis.Pass, call *ast.CallExpr) bool
• func IsLocalObject(obj types.Object) bool
• func IsStringLiteral(expr ast.Expr) bool
• func RhsExprForIndex(rhs []ast.Expr, idx int) (ast.Expr, bool)

Functions

func IsFmtErrorf

func IsFmtErrorf(pass *analysis.Pass, call *ast.CallExpr) bool

IsFmtErrorf reports whether call is a call to fmt.Errorf (including aliases).

func IsLocalObject

func IsLocalObject(obj types.Object) bool

IsLocalObject reports whether obj is a local (non-package-scope) object.

func IsStringLiteral

func IsStringLiteral(expr ast.Expr) bool

IsStringLiteral reports whether expr is a string literal.

func RhsExprForIndex

func RhsExprForIndex(rhs []ast.Expr, idx int) (ast.Expr, bool)

RhsExprForIndex returns the RHS expression mapped to idx when available. When rhs has a single expression, only idx==0 is considered mapped.
