Functions

func By

func By(m Matcher, root string) (result *list.List, err error)

By returns a list of files whose names match

func ByName

func ByName(pattern, root string) (result *list.List, err error)

ByName returns a list of files whose names match the shell like pattern

Example

os.Chdir(testRoot)
result, _ := ByName("*.txt", ".")
for e := result.Front(); e != nil; e = e.Next() {
	if s, ok := e.Value.(string); ok {
		fmt.Println(s)
	}
}

Output:

a.txt
b.txt

func InFile

func InFile(pattern, file string) (result *list.List, err error)

InFile opens and the file and uses InStream to find references

func InStream

func InStream(pattern string, stream io.Reader) *list.List

InStream works much like grep, finding references by the given pattern

Types

type Matcher

type Matcher interface {
	Match(path string) bool
}

func NewRegexp

func NewRegexp(ex *regexp.Regexp) Matcher

func NewShellPattern

func NewShellPattern(pattern string) Matcher

type Ref

type Ref struct {
	LineNo int
	Line   string
}

Ref points to a line in a file starting from 0

func (*Ref) String

func (ref *Ref) String() string
