BaseConv
Utility to convert numbers from base 10 integers to base X strings and back again. Based on Django's baseconv.py utility.
Documentation
Read the documentation at godoc.org.
Usage
func Example() {
encoded := baseconv.Base36.Encode(1234)
fmt.Println(encoded)
decoded, err := baseconv.Base36.Decode(encoded)
if err != nil {
panic(err)
}
fmt.Print(decoded)
// Output:
// ya
// 1234
}
func Example_base11() {
base11, err := baseconv.New("0123456789-", "$")
if err != nil {
panic(err)
}
encoded := base11.Encode(-1234)
fmt.Println(encoded)
decoded, err := base11.Decode(encoded)
if err != nil {
panic(err)
}
fmt.Print(decoded)
// Output:
// $-22
// -1234
}

Overview ¶
Convert numbers from base 10 integers to base X strings and back again.
Example ¶
package main
import (
"fmt"
"github.com/enricofoltran/baseconv"
)
func main() {
encoded := baseconv.Base36.Encode(1234)
fmt.Println(encoded)
decoded, err := baseconv.Base36.Decode(encoded)
if err != nil {
panic(err)
}
fmt.Print(decoded)
}
Output: ya 1234
Example (Base11) ¶
package main
import (
"fmt"
"github.com/enricofoltran/baseconv"
)
func main() {
base11, err := baseconv.New("0123456789-", "$")
if err != nil {
panic(err)
}
encoded := base11.Encode(-1234)
fmt.Println(encoded)
decoded, err := base11.Decode(encoded)
if err != nil {
panic(err)
}
fmt.Print(decoded)
}
Output: $-22 -1234
