Functions

func CheckPackages

func CheckPackages(pkgPaths []string, ignore map[string]*regexp.Regexp, blank bool, types bool) error

CheckPackages checks packages for errors. ignore is a map of package names to regular expressions. Identifiers from a package are checked against its regular expressions and if any of the expressions match the call is not checked. If blank is true then assignments to the blank identifier are also considered to be ignored errors. If types is true then ignored type assertion results are also checked

Types

type UncheckedErrors

type UncheckedErrors struct {
	// Errors is a list of all the unchecked errors in the package.
	// Printing an error reports its position within the file and the contents of the line.
	Errors []error
}

UncheckedErrors is returned from the CheckPackage function if the package contains any unchecked errors.

func (UncheckedErrors) Error

func (e UncheckedErrors) Error() string

func (UncheckedErrors) Len

func (e UncheckedErrors) Len() int

Len is the number of elements in the collection.

func (UncheckedErrors) Swap

func (e UncheckedErrors) Swap(i, j int)

Swap swaps the elements with indexes i and j.
