Use Cases

Personal names declension

This example shows how to use the library to decline Ukrainian anthroponyms. The example code takes an input object that includes grammatical gender, given name, patronymic name, and family name of a person. Then, it passes the input object to the shevchenko.inVocative() method, which returns the declined version of the input anthroponym in vocative case. Finally, it logs the output object to the console.

const shevchenko = require('shevchenko');

async function main() {
  const input = {
    gender: 'masculine',
    givenName: 'Тарас',
    patronymicName: 'Григорович',
    familyName: 'Шевченко'
  };

  const output = await shevchenko.inVocative(input);

  console.log(output); // { givenName: "Тарасе", patronymicName: "Григоровичу", familyName: "Шевченку" }
}

main().catch((error) => console.error(error));

Automatic grammatical gender detection

This example shows how to use the library to automatically detect the grammatical gender of a Ukrainian anthroponym. The example code takes an input object that includes given name, patronymic name, and family name of a person. Then, it passes the input object to the shevchenko.detectGender() method, which returns the detected gender of the input anthroponym. If the method fails to detect the grammatical gender, it throws an error. Finally, it logs the declined version of the input object in vocative case to the console.

const shevchenko = require('shevchenko');

async function main() {
  const anthroponym = {
    givenName: 'Лариса',
    patronymicName: 'Петрівна',
    familyName: 'Косач-Квітка'
  };

  const gender = await shevchenko.detectGender(anthroponym); // "feminine"
  if (gender == null) {
    throw new Error('Failed to detect grammatical gender.');
  }

  const input = { ...anthroponym, gender };

  const output = await shevchenko.inVocative(input);

  console.log(output); // { givenName: "Ларисо", patronymicName: "Петрівно", familyName: "Косач-Квітко" }
}

main().catch((error) => console.error(error));
