Lipitva NPM | npm.io

lipitva

lipitva is a modular and efficient javascript port of python sanscript. In logic, It diverges from sanscript, only when the nature of JavaScript, TypeScript justifies such diverging. Interfaces are fine tuned for js eco-system.

Installation

npm

npm install --save lipitva

Usage

Basic usage

For basic use cases, lipitva exports a singleton named lip. It is a pre-configured instance of Lip type. you can use it as follows

// ES6
import lip from 'lipitva';

// Browser
lip
// or
window.lip

const content = 'धर्मक्षेत्रे कुरुक्षेत्रे <b>समवेता</b> युयुत्सवः ।';
let teluguContent = lip.t({
    data: content,
    from: 'devanagari',
    to: 'telugu',
    suspendOn: new Set(['<']), // optional
    suspendOff: new Set(['>']), // optional
})
console.log(teluguContent); // logs "ధర్మక్షేత్రే కురుక్షేత్రే <b>సమవేతా</b> యుయుత్సవః ।"

We can also replace text-content of an HTMLElement with it's transliterated form using lip.te method. (te : transliterate-element). This method transliterates in-place in DOM. Thus it doesn't re-render DOM, or doesn't remove any callbacks. This operation's recursive nature also can be specified.

const elem = document.getElementById('my-element);
lip.te({
    elem,
    from: 'devanagari',
    to: 'gujarati',
    recursive: true, // optional
});

Modular usage (Recommended)

Instead of using default export, we can use lipitva in modular way. This way we can bundle only required functionality, and required scripts in our apps. This way we can also use enums, functional tools which are not exported in singleton. Following is an example, to demo how to include only devanagari, telugu, itrans scripts in our app.

// module A:
// A scripts registry, to manage scripts and script-maps efficiently
import { ScriptsRegistry } from 'lipitva/dist/registry';
// A helper interface to invoke various tools easily. default export `lip` is instance of this class.
import { Lip } from 'lipitva/dist/Lip';

import { Telugu } from 'lipitva/dist/scripts/brahmic/Telugu';
import { Devanagari } from 'lipitva/dist/scripts/brahmic/Devanagari'
import { Itrans } from 'lipitva/dist/scripts/roman/ITrans'

const registry = new ScriptsRegistry();
registry.register([Telugu, Devanagari, Itrans]);

// Now we can export our custom minimal instance of Lip from this module, and can use it through out our app.
export const customLip = new Lip(registry);

// module B
import { Script } from 'lipitva/dist/enum';
import { customLip } from './A';

const tVal = customLip.t({
    data: 'रामालयम्',
    from: Script.DEVANAGARI,
    to: Script.TELUGU,
}); // equals to రామాలయమ్

As lipitva allows efficient tree-shaking, in final bundle only those imported modules will be included. we can use functional tools like transliterate, transliterateElem directly too, instead of using OOP friendly Lip interface.

Development

Stack

Written in ES6 modules.
Written in strict TypeScript
Outputs in three module systems. commonJs in dist, ES6 in dist-esm, and umd bundles. rollup is used for umd-bundling
Strictly adheres to airbnb style guide. Before build, code should be validated against this style guide using ESLint (npm run lint). It is recommended to use ESLint plugin for IDEs like vscode. Thus they will lint code while you are coding, and provide auto formatting functionality.
