ltsv

High performance LTSV (Labeled Tab Separeted Value) parser for Go.

About LTSV: http://ltsv.org/

Labeled Tab-separated Values (LTSV) format is a variant of 
Tab-separated Values (TSV). Each record in a LTSV file is represented 
as a single line. Each field is separated by TAB and has a label and
 a value. The label and the value have been separated by ':'. With 
the LTSV format, you can parse each line by spliting with TAB (like 
original TSV format) easily, and extend any fields with unique labels 
in no particular order.

Installation

go get github.com/Wing924/ltsv

Examples

package main

import (
    "fmt"
    "github.com/Wing924/ltsv"
)

func main() {
    line := []byte("foo:123\tbar:456")
    record, err := ltsv.ParseLineAsMap(line, nil)
    if err != nil {
        panic(err)
    }
    fmt.Printf("%#v", record) // map[string]string{"foo":"123", "bar":"456"}
}
