DSV parser for Go
DSV is delimiter-separated values parser for GO. It will parse lines and insert data into any type of struct. DSV supports both simple structs and structs with tagging.
go get github.com/angu1ss/dsv
Quickstart
DSV inserts data into struct by fields order.
import (
"fmt"
"os"
"testing"
)
type TestRow struct {
Name string
Age int
Gender string
Active bool
}
func main() {
file, _ := os.Open("example.tsv")
defer file.Close()
data := TestRow{}
parser, _ := NewTsvParser(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 `dsv:"name"`
Age int `dsv:"age"`
Gender string `dsv:"gender"`
Active bool `dsv:"bool"`
}
Supported field types
Currently, library supports limited fields:
- string
- bool
- int, base 10
- int8, base 10
- int16, base 10
- int32, base 10
- int64, base 10
- unit, base 10
- unit8, base 10
- unit16, base 10
- unit32, base 10
- unit64, base 10
- float32, delimiter is point, comma will be ignored
- float64, delimiter is point, comma will be ignored
- complex64
- complex128
