Getting Started

Import the library by spacename

using Doushi;

Now you can call this static function to conjugate the verb

// Will auto detect that this is a Godan verb ending in る and will return its conjugation
var conj = Conjugator.Conjugate("作る", "つくる");
// Manually specifiy the verb type
var conj = Conjugator.Conjugate("作る", Doushi.Type.GODAN_RU, "つくる");

The Conjugate() function is going to return an Inflections class that contains all the verb conjugation in the supported forms, will return null in case the verb is not recognized as a verb

Other Public Functions

The TryFindType() is a public function that is used by the Conjugate() function to try and find the verb type

// Will return Type.SPECIAL_KURU
var type = Conjugator.TryFindType("来る", "くる");

The DicToDoushiType() function is used to convert the supported JMDict string types which are ["v1", "v5b", "v5g", "v5k", "v5k-s", "v5m", "v5n", "v5r", "v5r-i", "v5s", "v5t", "v5u", "v5u-s", "vk", "vs-s", "vs-i"] to Doushi.Type enum

// Will return Type.GODAN_MU
var type = Conjugator.DicToDoushiType("v5m")

Inflections

var conj = Conjugator.Conjugate("行く", "いく");
if (conj != null)
{
	Console.WriteLine($"　-> Non-Past: {conj.NonPast.Affirmative} | {conj.NonPast.Negative}\n");
	Console.WriteLine($"　-> Non-Past Polite: {conj.NonPastPolite.Affirmative} | {conj.NonPastPolite.Negative}\n");
	Console.WriteLine($"　-> Past: {conj.Past.Affirmative} | {conj.Past.Negative}\n");
	Console.WriteLine($"　-> Past Polite: {conj.PastPolite.Affirmative} | {conj.PastPolite.Negative}\n");

	Console.WriteLine($"　-> Potential: {conj.Potential.Affirmative} | {conj.Potential.Negative}\n");
	Console.WriteLine($"　-> Passive: {conj.Passive.Affirmative} | {conj.Passive.Negative}\n");
	Console.WriteLine($"　-> Causative: {conj.Causative.Affirmative} | {conj.Causative.Negative}\n");
	Console.WriteLine($"　-> Causative Passive: {conj.CausativePassive.Affirmative} | {conj.CausativePassive.Negative}\n");
	Console.WriteLine($"　-> Imperative: {conj.Imperative.Affirmative} | {conj.Imperative.Negative}\n");
