chunkedreader is a light weight wrapper for Go's bufio that enables reading of byte streams in fixed size chunks.
It makes use of bufio.Scanner's custom split function capability, which otherwise is meant for splitting
based on delimiters, to split based on fixed lengths.
This could especially be useful for reading continuous fixed length messages from a TCP stream, emulating "packets", for instance.
go get github.com/knadh/chunkedreader
package main
import (
"github.com/knadh/chunkedreader"
)
func main() {
// Open file for reading.
f, _ := os.Open("test.txt")
// Initialize the reader to read chunks of 4 bytes.
ch := chunkedreader.New(f, 4)
for ch.Read() {
// Length of b will always be 4, or less than 4 if there
// are no more bytes available to read.
b := ch.Bytes()
}
}
