Text Encoding and Decoding

This repository contains a collection of text encoding and decoding functions implemented in JavaScript. These functions can be used to transform text using various encoding techniques.

Install

npm install stringcompression

Functions

The following functions are available:

• encodeKeys(input): Encodes the keys in the input text using a predefined dictionary. Words in the input that match a key in the dictionary are replaced with a caret symbol (^) followed by the corresponding key.

• decodeKeys(input): Decodes the keys in the input text using a predefined dictionary. Words in the input that start with a caret symbol (^) followed by a key are replaced with the corresponding value from the dictionary.

• compressIt(input): Performs a series of encoding operations on the input text. It applies the Burrows-Wheeler Transform (BWT), Move-to-Front (MTF) encoding, Elias Gamma Coding (EGC), and Bijective Ternary Transformation (BTT) using the provided keys and dictionary.

• decompressIt(input): Performs a series of decoding operations on the input code. It reverses the encoding operations applied by the encodeIt function using the provided keys and dictionary.

Usage

To use these functions in your JavaScript code, you can require the module and call the desired functions:

const { encodeKeys, decodeKeys, compressIt, decompressIt } = require('text-encoding');

const encoded = encodeKeys('Hello, world!');
console.log(encoded); // Outputs: 'Hello, ^WRUJ^RBT^'

const decoded = decodeKeys('Hello, ^WRUJ^RBT^');
console.log(decoded); // Outputs: 'Hello, world!'

const encodedText = compressIt('Hello, world!');
console.log(encodedText); // Outputs: encoded text

const decodedText = decompressIt(encodedText);
console.log(decodedText); // Outputs: 'Hello, world!'
