Functions ¶

func BoolConst ¶

func BoolConst(pass *analysis.Pass, expr ast.Expr) bool

func CallName ¶

func CallName(pass *analysis.Pass, call *ast.CallExpr) string

func ExprToInt ¶

func ExprToInt(pass *analysis.Pass, expr ast.Expr) (int64, bool)

func ExprToString ¶

func ExprToString(pass *analysis.Pass, expr ast.Expr) (string, bool)

func File ¶

func File(pass *analysis.Pass, node Positioner) *ast.File

func Generator ¶

func Generator(pass *analysis.Pass, pos token.Pos) (facts.Generator, bool)

Generator returns the generator that generated the file containing pos. It ignores //line directives.

func IntegerLiteral ¶

func IntegerLiteral(pass *analysis.Pass, node ast.Node) (types.TypeAndValue, bool)

func IsBoolConst ¶

func IsBoolConst(pass *analysis.Pass, expr ast.Expr) bool

func IsCallTo ¶

func IsCallTo(pass *analysis.Pass, node ast.Node, name string) bool

func IsCallToAny ¶

func IsCallToAny(pass *analysis.Pass, node ast.Node, names ...string) bool

func IsGenerated ¶

func IsGenerated(pass *analysis.Pass, pos token.Pos) bool

IsGenerated reports whether pos is in a generated file, It ignores //line directives.

func IsGoVersion ¶

func IsGoVersion(pass *analysis.Pass, minor int) bool

func IsInTest ¶

func IsInTest(pass *analysis.Pass, node Positioner) bool

func IsIntegerLiteral ¶

func IsIntegerLiteral(pass *analysis.Pass, node ast.Node, value constant.Value) bool

func IsMain ¶

func IsMain(pass *analysis.Pass) bool

IsMain reports whether the package being processed is a package main.

func IsMainLike ¶

func IsMainLike(pass *analysis.Pass) bool

IsMainLike reports whether the package being processed is a main-like package. A main-like package is a package that is package main, or that is intended to be used by a tool framework such as cobra to implement a command.

Note that this function errs on the side of false positives; it may return true for packages that aren't main-like. IsMainLike is intended for analyses that wish to suppress diagnostics for main-like packages to avoid false positives.

func IsNil ¶

func IsNil(pass *analysis.Pass, expr ast.Expr) bool

func IsOfType ¶

func IsOfType(pass *analysis.Pass, expr ast.Expr, name string) bool

func Match ¶

func Match(pass *analysis.Pass, q pattern.Pattern, node ast.Node) (*pattern.Matcher, bool)

func MatchAndEdit ¶

func MatchAndEdit(pass *analysis.Pass, before, after pattern.Pattern, node ast.Node) (*pattern.Matcher, []analysis.TextEdit, bool)

func MayHaveSideEffects ¶

func MayHaveSideEffects(pass *analysis.Pass, expr ast.Expr, purity facts.PurityResult) bool

MayHaveSideEffects reports whether expr may have side effects. If the purity argument is nil, this function implements a purely syntactic check, meaning that any function call may have side effects, regardless of the called function's body. Otherwise, purity will be consulted to determine the purity of function calls.

func Preorder ¶

func Preorder(pass *analysis.Pass, fn func(ast.Node), types ...ast.Node)

func PreorderStack ¶

func PreorderStack(pass *analysis.Pass, fn func(ast.Node, []ast.Node), types ...ast.Node)

func SelectorName ¶

func SelectorName(pass *analysis.Pass, expr *ast.SelectorExpr) string

Types ¶

type Positioner ¶

type Positioner interface {
	Pos() token.Pos
}
