Functions

func CloseAndLogError

func CloseAndLogError(closer io.Closer, location string)

CloseAndLogError closes the given io.Closer and reports any errors found as a warning in the log

func HasAnyOfPrefixes

func HasAnyOfPrefixes(input string, prefixes ...string) bool

HasAnyOfPrefixes returns an indication if the given string has any of the given prefixes.

func IsErrPath

func IsErrPath(err error) bool

func IsErrPathPermission

func IsErrPathPermission(err error) bool

func IsPipedInput

func IsPipedInput() (bool, error)

IsPipedInput returns true if there is no input device, which means the user **may** be providing input via a pipe.

func MatchNamedCaptureGroups

func MatchNamedCaptureGroups(regEx *regexp.Regexp, content string) map[string]string

MatchNamedCaptureGroups takes a regular expression and string and returns all of the named capture group results in a map. This is only for the first match in the regex. Callers shouldn't be providing regexes with multiple capture groups with the same name.

func Tprintf

func Tprintf(tmpl string, data map[string]interface{}) string

Tprintf renders a string from a given template string and field values

func TruncateMiddleEllipsis

func TruncateMiddleEllipsis(input string, maxLen int) string

type ErrPath

type ErrPath struct {
	Path string
	Err  error

func (ErrPath) Error

func (e ErrPath) Error() string

type StringSet

type StringSet map[string]struct{}

StringSet represents a set of string types.

func NewStringSet

func NewStringSet() StringSet

NewStringSet creates a new empty StringSet.

func NewStringSetFromSlice

func NewStringSetFromSlice(start []string) StringSet

NewStringSetFromSlice creates a StringSet populated with values from the given slice.

func (StringSet) Add

func (s StringSet) Add(i string)

func (StringSet) Contains

func (s StringSet) Contains(i string) bool

Contains indicates if the given string is contained within the set.

func (StringSet) Remove

func (s StringSet) Remove(i string)
