Overview

Example (Head)

package main

import (
	"fmt"
	"log"

	headtail "github.com/sbleks/head-tail"
)

func main() {

	lines, err := headtail.Head(`testdata/somefile`, 3)
	if err != nil {
		log.Panicln(err)
	}
	fmt.Println(lines)

}

Output:

[alpha beta gamma]

Example (Head_over_limit)

package main

import (
	"fmt"
	"log"

	headtail "github.com/sbleks/head-tail"
)

func main() {

	lines, err := headtail.Head(`testdata/somefile`, 100)
	if err != nil {
		log.Panicln(err)
	}
	fmt.Println(lines)

}

Output:

[alpha beta gamma delta]

Example (Tail)

package main

import (
	"fmt"
	"log"

	headtail "github.com/sbleks/head-tail"
)

func main() {

	lines, err := headtail.Tail(`testdata/somefile`, 3)
	if err != nil {
		log.Panicln(err)
	}
	fmt.Println(lines)

}

Output:

[beta gamma delta]

Example (Tail_over_limit)

package main

import (
	"fmt"
	"log"

	headtail "github.com/sbleks/head-tail"
)

func main() {

	lines, err := headtail.Tail(`testdata/somefile`, 100)
	if err != nil {
		log.Panicln(err)
	}
	fmt.Println(lines)

}

Output:

[alpha beta gamma delta]
