Extract a archive​

package main

import (
	"fmt"
	"os"

	"codeberg.org/JakobDev/asar-go"
)

func main() {
    archive, err := asar.OpenFile("path", &asar.ReadOptions{})
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    defer archive.Close()

    err = archive.ExtractAll("extract_path")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
}

Read a file​

package main

import (
	"fmt"
	"os"
    "io"

	"codeberg.org/JakobDev/asar-go"
)

func main() {
    archive, err := asar.OpenFile("path", &asar.ReadOptions{})
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    defer archive.Close()

    entry, err := archive.GetEntry("test.txt")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    reader, err := entry.GetReader()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    content, err := io.ReadAll(reader)
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    fmt.Println(string(content))
}
