Encode
bencode.Encode takes a map[string]interface{} as argument and returns a byte array. Example:
package main
import (
"fmt"
"github.com/marksamman/bencode"
)
func main() {
dict := make(map[string]interface{})
dict["string key"] = "hello world"
dict["int key"] = 123456
fmt.Printf("bencode encoded dict: %s\n", bencode.Encode(dict))
}Decode
bencode.Decode takes an io.Reader as argument and returns (map[string]interface{}, error). Example:
package main
import (
"fmt"
"log"
"os"
"github.com/marksamman/bencode"
)
func main() {
file, err := os.Open(os.Args[1])
if err != nil {
log.Fatal(err)
}
defer file.Close()
dict, err := bencode.Decode(file)
if err != nil {
log.Fatal(err)
}
fmt.Printf("string: %s\n", dict["string key"].(string))
fmt.Printf("int: %d\n", dict["int key"].(int64))
}
