Functions

func HasMeta

func HasMeta(s string) bool

HasMeta reports whether path contains any magic glob characters.

Types

type CombinedFilter

type CombinedFilter struct {
	// contains filtered or unexported fields
}

CombinedFilter matches if ANY of its sub-filters match (OR logic).

func (*CombinedFilter) Match

func (f *CombinedFilter) Match(s string) bool

type Filter

type Filter interface {
	Match(string) bool
}

func Compile

func Compile(filters []string) (Filter, error)

Compile takes a list of string filters and returns a Filter interface for matching a given string against the filter list (OR logic).

Patterns surrounded by / are treated as regular expressions:

f, _ := Compile([]string{"*error*", "/(?i)panic|segfault/"})
f.Match("an error occurred")    // true (glob match)
f.Match("KERNEL PANIC")         // true (regex match)
f.Match("normal log")           // false

Plain patterns support glob matching:

f, _ := Compile([]string{"cpu", "mem", "net*"})
f.Match("cpu")     // true
f.Match("network") // true
f.Match("memory")  // false

func NewIncludeExcludeFilter

func NewIncludeExcludeFilter(
	include []string,
	exclude []string,
) (Filter, error)

func NewIncludeExcludeFilterDefaults

func NewIncludeExcludeFilterDefaults(
	include []string,
	exclude []string,
	includeDefault bool,
	excludeDefault bool,
) (Filter, error)

type IncludeExcludeFilter

type IncludeExcludeFilter struct {
	// contains filtered or unexported fields
}

func (*IncludeExcludeFilter) Match

func (f *IncludeExcludeFilter) Match(s string) bool
