retext

What is retext?

Retext is a natural language processing (NLP) framework for analyzing and manipulating text. It provides a variety of plugins to perform tasks such as spell checking, sentiment analysis, and readability scoring.

What are retext's main functionalities?

Spell Checking

This feature allows you to check the spelling of text. The code sample demonstrates how to use the `retext-spell` plugin with an English dictionary to identify spelling errors in a given text.

const retext = require('retext');
const retextSpell = require('retext-spell');
const dictionary = require('dictionary-en');
const report = require('vfile-reporter');

retext()
  .use(retextSpell, dictionary)
  .process('speling errror', function (err, file) {
    console.error(report(err || file));
  });

Sentiment Analysis

This feature allows you to analyze the sentiment of text. The code sample demonstrates how to use the `retext-sentiment` plugin to determine the sentiment polarity and valence of a given text.

const retext = require('retext');
const retextSentiment = require('retext-sentiment');
const report = require('vfile-reporter');

retext()
  .use(retextSentiment)
  .process('I love programming!', function (err, file) {
    console.error(report(err || file));
    console.log(file.data); // { polarity: 3, valence: 1 }
  });

Readability Scoring

This feature allows you to score the readability of text. The code sample demonstrates how to use the `retext-readability` plugin to determine the readability age of a given text.

const retext = require('retext');
const retextReadability = require('retext-readability');
const report = require('vfile-reporter');

retext()
  .use(retextReadability, { age: 18 })
  .process('The cat sat on the mat.', function (err, file) {
    console.error(report(err || file));
    console.log(file.data); // { readability: { age: 6 } }
  });

• API by unified
• Parses natural language to the tree with retext-latin
• nlcst syntax tree
• Plugins transform the tree
• Compiles the tree to markdown using retext-stringify

Don’t need the parser? Or the compiler? That’s OK.
