Roman numerals parser (Go)

Implements a Roman type that supports text marshalling / unmarshalling.

Usage

  import (
    "fmt"
    
    "github.com/ghen/roman-numerals/roman"
  )

  func main() {

    var r Roman
    if err := r.UnmarshalText([]byte("XIV")); err != nil {
      panic(err)
    }

    fmt.Printf("%s = %d", r.String(), r.Value)
  }

Notes

Not covered in roman package:

• Text tokenization (trim the whitespace before parsing the value)
• Text normalization (only upper case ASCII characters are accepted)
• Validation (roman number characters are parsed as long as they do not exceed the maximum allowed value of 3,999)
