[![Go Report Card](https://goreportcard.com/badge/github.com/raspi/searchreader)](https://goreportcard.com/report/github.com/raspi/searchreader)

Search single `bytes.Reader` with different `strings.Reader`(s) containing the search byte(s) or string(s).

Part of [heksa issue](https://github.com/raspi/heksa/issues/8).

```go

func main() {

	// Source

	src := bytes.NewReader(

		[]byte("heLLo, world!\000\000"),

	)

	// What to search

	search1 := strings.NewReader("\000")

	search2 := strings.NewReader(`ll`)

	sr := searchreader.New(src,

		searchreader.WithCaseSensitive(search1),

		searchreader.WithCaseInsensitive(search2),

	)

	buffer := make([]byte, 1024)

	_, results, err := sr.Read(buffer)

	if err != nil {

		panic(err)

	}

	for _, result := range results {

		fmt.Printf(`found match at position %d that matches search%d %d`+"\n", result.StartPosition, 1+result.Index, result.Length)

	}

}

```

Outputs:

```

found match at position 2 that matches search2 2

found match at position 13 that matches search1 1

found match at position 14 that matches search1 1

```

## Some goals

* Convert searched string(s) into different encodings such as UTF-8, ISO-8859-1 and ISO-8859-15 so that you can search more efficiently at once

## Is it any good?

Yes.
