searchreader

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

Part of heksa issue.

funcmain() {
// Sourcesrc:=bytes.NewReader(
[]byte("heLLo, world!\000\000"),
)
// What to searchsearch1:=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)
iferr!=nil {
panic(err)
}
for_, result:=rangeresults {
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.
