inflector

Inflector is a project that aims to generate inflections of words based on specified rules and exceptions. The rules must be specified using Regular expressions. Language data can be fed as a JSON file.

Inflector is in the early stages of development. Any contribution is welcome.

Usage

• Clone the repository with git clone https://github.com/V-Volte/inflector
• Install the dependencies with npm install
• Create a file called index.js (or anything else) in the root directory of the project.

I've prepared an example file that defines a subset of the conjugation and declension rules for Latin. You can find this file as latin.json in the examplepatterns directory.

To load the Latin language from this file, all you have to do is:

const LanguageConstructor = require('./src/core/LanguageConstructor');

const latin = LanguageConstructor.constructLanguageFromJSONFile('./examplepatterns/latin.json');

Now, you can inflect any word using the inflectNoun or inflectVerb method of the Language class:

const augustus = "Augustus";
const amare = "Amāre";

console.log(latin.inflectNoun(augustus, "First Declension", "Plural", "Plural", "Genitive"));
console.log(
    latin.inflectVerb(amare, "First Conjugation", "Indicative", "Active", "Present", "Singular", "First")
);

Or, you can use the generateMarkdownInflectionTable() method of InflectionClass to generate a Markdown table of all the inflections of a word:

const fs = require('fs');
fs.writeFileSync('inflections.md', latin.getNounInflectionClass("First Declension")?.generateMarkdownInflectionTable(augustus, "Masculine"))

Defining a language

Currently, defining a new language and rules in JSON is very tedious and frankly, impossible for a normal human. Even generating this file took me about 15 minutes with Copilot automatically adding the inflection patterns in JavaScript. I'm currently working on a better way to define the rules, probably using a different JSON structure, or maybe something like YAML.

If, however, you have access to Copilot or any other AI that can generate code, you can use the addInflectionPattern function and others of its ilk to create a Language object, and save it by stringifying it into a JSON file. This is how I generated the latin.json file:

const latin = new Language(
    "Latin",
    ["Indicative", "Subjunctive", "Imperative"],
    ["Present", "Imperfect", "Future", "Perfect", "Pluperfect", "Future Perfect"],
    ["Singular", "Plural"],
    ["First", "Second", "Third"],
    ["Active", "Passive"],
    ["Masculine", "Feminine", "Neuter"],
    ["Nominative", "Genitive", "Dative", "Accusative", "Ablative", "Vocative", "Locative"]
);

const firstConjugation = new VerbInflectionClass(
    "First Conjugation",
    "(.*)(āre)",
    latin.moods,
    latin.voices,
    latin.tenses,
    latin.numbers,
    latin.persons
);

firstConjugation.addInflectionPattern(
    "Indicative",
    "Active",
    "Present",
    "Singular",
    "First",
    new InflectionPattern(firstConjugation.rootPattern, ["ō"], [1])
);

...and so on.
