Humanized string to number

[mgibas]

Is there any chance to convert humanized string to int like this:

var value = "first".ToNumber() // value = 1;
var value = "second".ToNumber() // value = 2;
var value = "17th".ToNumber() // value = 17;

?

No

This is not currently possible but could be a useful feature. Thanks for the suggestion.

[hazzik]

I don't think that this is possible at all as Humanizer definitely not an
NLP library.

[MehdiK]

This isn't quite NLP. It's not very easy but it should be doable with a set of predefined rules, much like how the ToWords or Ordinalize work.

I implemented that already...kind of :)
In a time pressure my temporary solution looks like this (please don't judge I know its wrong :) ):

public static int ToNumber(this string @this)
{
      for (int i = 0; i < 1000000; i++)
      {
        if (i.ToOrdinalWords(new CultureInfo("en-US")).ToLower() == @this.ToLower())
          return i;
      }

      throw new ArgumentException(string.Format("Invalid quantifier provided: '{0}'", @this));
 }

I just hope that there is much cleaner solution for it :)

[MehdiK]

LOL. That's not what I had in mind.

I suggest you at least cache the entries so you don't have to calculate
them on each call.

This is a problem that's been tackled before. I don't think it would be very difficult to add for English. What are some issues with supporting other cultures?

[MehdiK]

I agree @jzebedee. It's better to have a feature that can be done for all languages; that said, I honestly don't mind if there are features that are only supported in a couple of languages as long as English support is in there.

Could we model a solution similar to what Numsense has done already?

var englishNumeral = Numeral.English.ToNumeral(42);
// englishNumeral is "forty-two"

[clairernovotny]

If Numsense is doing this already, is there a further need to incorporate that into Humanizer? Why not just use Numsense directly?
