tsv

TSV parser for Go

tsv is tab-separated values parser for GO. It will parse lines and insert data into any type of struct. tsv supports both simple structs and structs with tagging.

Quickstart

tsv inserts data into struct by fields order.

import (
    "fmt"
    "os"
    "testing"
    )

type TestRow struct {
  Name   string // 0
  Age    int    // 1
  Gender string // 2
  Active bool   // 3
}

func main() {

  file, _ := os.Open("example.tsv")
  defer file.Close()

  data := TestRow{}
  parser, _ := NewParser(file, &data)

  for {
    eof, err := parser.Next()
    if eof {
      return
    }
    if err != nil {
      panic(err)
    }
    fmt.Println(data)
  }

}

You can define tags to struct fields to map values.

type TestRow struct {
  Name   string `tsv:"name"`
  Age    int    `tsv:"age"`
  Gender string `tsv:"gender"`
  Active bool   `tsv:"bool"`
}
