NameCase

npm Build Status Coverage Status npm bundle size

NameCase is a fully typed implementation of Lingua::EN::NameCase, a library for converting strings to be properly cased. This is good for converting denormalized data to human friendly data.

Description

Forenames and surnames are often stored either entirely in UPPERCASE or lowercase. This library allows you to convert names into the correct case where possible. Although forenames and surnames are typically stored separately if they do appear in a single string, whitespace-separated, NameCase deals correctly with them.

Currently NameCase correctly name cases names which include any of the following:

Mc, Mac, al, el, ap, bat, ben, bin, binti, binte, da, de, das, dos, delle, della, di, du, del, der, den, ten, ter, la, le, lo, van and von.

It correctly deals with names which contain apostrophes and hyphens too.

Installation

Via npm

npm install @foundernest/namecase

Via yarn

yarn add @foundernest/namecase

Usage

Basic usage

import { nameCase } from '@foundernest/namecase';

nameCase('KEITH');               // => Keith
nameCase('LEIGH-WILLIAMS');      // => Leigh-Williams
nameCase('MCCARTHY');            // => McCarthy
nameCase("O'CALLAGHAN");         // => O'Callaghan
nameCase('ST. JOHN');            // => St. John
nameCase('VON STREIT');          // => von Streit
nameCase('AP LLWYD DAFYDD');     // => ap Llwyd Dafydd
nameCase('HENRY VIII');          // => Henry VIII
nameCase('VAN DYKE');            // => van Dyke

Advance usage

You can override the default options by calling the nameCase function with the EnvironmentOptions optional parameter:

import { nameCase } from '@foundernest/namecase';

nameCase('macmurdo');                        // => MacMurdo
nameCase('macmurdo', { irish: false });      // => Macmurdo

You can also set the options of all the subsequent calls:

import { nameCase, setOptions } from '@foundernest/namecase';

nameCase('macmurdo');               // => MacMurdo
setOptions({ irish: false });
nameCase('macmurdo');               // => Macmurdo

Or you can even create a new Environment object with custom options:

import Environment from '@foundernest/namecase';

const ncEnv = new Environment({
  lazy: false
  roman: false
});

ncEnv.nameCase('Na li');     // => Na Li

Options

  • lazy – Default: true. Do not do anything if string is already mixed case and lazy option is true.
  • irish – Default: true. Correct "Mac" exceptions.
  • spanish – Default: true. Correct spanish conjunctions y, e or i.
  • roman – Default: true. Correct roman numbers.
  • hebrew – Default: true. Correct ben, bat.
  • postnominal – Default: true. Correct post-nominal. e.g. PhD.

Exclude Post-Nominals

import { excludePostNominals, nameCase } from '@foundernest/namecase';

nameCase('ČERNÝ MOST');         // Černý MOst
excludePostNominals('MOst');
nameCase('ČERNÝ MOST');         // Černý Most
