LTSV (Labeled Tab-separated Values) reader/writer for Go language.

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.

Example

Reader

::

package main

import ( "bytes" "fmt" "github.com/najeira/ltsv" )

func main() { data := time:05/Feb/2013:15:34:47 +0000 host:192.168.50.1 req:GET / HTTP/1.1 status:200 time:05/Feb/2013:15:35:15 +0000 host:192.168.50.1 req:GET /foo HTTP/1.1 status:200 time:05/Feb/2013:15:35:54 +0000 host:192.168.50.1 req:GET /bar HTTP/1.1 status:404 b := bytes.NewBufferString(data)

// Read LTSV file into map[string]string
reader := ltsv.NewReader(b)
records, err := reader.ReadAll()
if err != nil {
	panic(err)
}

// dump
for i, record := range records {
	fmt.Printf("===== Data %d\n", i)
	for k, v := range record {
		fmt.Printf("\t%s --> %s\n", k, v)
	}
}

}

Writer

::

package main

import ( "fmt" "bytes" "github.com/najeira/ltsv" )

func main() { data := []map[string]string { {"time": "05/Feb/2013:15:34:47 +0000", "host": "192.168.50.1", "req": "GET / HTTP/1.1", "status": "200"}, {"time": "05/Feb/2013:15:35:15 +0000", "host": "192.168.50.1", "req": "GET /foo HTTP/1.1", "status": "200"}, {"time": "05/Feb/2013:15:35:54 +0000", "host": "192.168.50.1", "req": "GET /bar HTTP/1.1", "status": "404"}, }

b := &bytes.Buffer{}
writer := ltsv.NewWriter(b)
err := writer.WriteAll(data)
if err != nil {
	panic(err)
}
fmt.Printf("%v", b.String())
