A Go MARC21 implementation.
This repository started as a fork of gitorious.org/marc21-go/marc21, but is - as of June 2017 - the new home of the MARC21 Go library.
As of August 2019, we are working on a revised implementation, as there are some edge cases the current implementation cannot handle.
file, _ := os.Open("somedata.mrc")
record, _ := marc21.ReadRecord(file)
_ = record.WriteTo(os.Stdout)package main
import (
"io"
"log"
"os"
"github.com/miku/marc21"
)
func main() {
for {
r, err := marc21.ReadRecord(os.Stdin)
if err == io.EOF {
break
}
if err != nil {
log.Fatal(err)
}
if _, err := r.WriteTo(os.Stdout); err != nil {
log.Fatal(err)
}
}
