Basic Usage

Install the library using npm or yarn:

npm i @digitallinguistics/word-aligner
yarn add @digitallinguistics/word-aligner

Import the module:

import alignWords from '@digitallinguistics/word-aligner';

Run the utility on an array of the lines you’d like to vertically align:

const lines = [
  `waxdungu qasi`,
  `waxt-qungu qasi`,
  `day-one man`,
];

const aligned = alignWords(lines);

The value of the aligned variable will be:

[
  "waxdungu   qasi",
  "waxt-qungu qasi",
  "day-one    man"
]

Note: word-aligner does not do automatic line detection. It will not know what type of line you are handing it (morphemes, glosses, translation, etc.). Only provide the lines you actually want aligned. Usually this means you will not provide a free translation line.

Options

Option	Default	Description
alignmentError	false	Specifies whether the library should throw an error if all lines do not have the same number of words.
groupWith	[]	Specifies a pair of characters to use to group words together in a line. Any words enclosed by these characters will be treated as a single word by the library.
