I'm trying to write tab separated values in a file using the tabwriter package in Go.
records map[string] []string
file, err := os.OpenFile(some_file, os.O_CREATE|os.O_WRONLY, 0644)
if err != nil {
log.Println(err)
}
w := new(tabwriter.Writer)
w.Init(file, 0, 4, 0, '\t', 0)
for _, v := range records {
fmt.Fprintln(w, v[0],"\t",v[1],"\t",v[2],"\t",v[3])
w.Flush()
}
The problem I'm facing is that the records written to the file have two additional spaces prepended to them. I added the debug flag and this is what I get in the file:
fname1 | mname1 | lname1 | age1
fname2 | mname2 | lname2 | age2
I'm unable to see where I'm going wrong. Any help is appreciated.
