Definition linker

Utility to automatically create links to definition URLs, in a given block of text/HTML.

A stemmer method must be provided to match the words given block of text/HTML with the configured definition words.

Usage

Basic

const natural = require('natural');
const definition_linker = require('definition-linker')({
    stem: function stem(text) {
        // keepStops=true
        return natural.PorterStemmerFr.tokenizeAndStem(text, true).join(' ');
    }
});
 
definition_linker.createIndex();
 
definition_linker.addToIndex('node.js', '#node.js');
definition_linker.addToIndex('logiciel libre', '#logiciel-libre');
// etc.
 
const html = definition_linker.addLinksInHtml('Node.js est un logiciel libre');

Advanced

addLinksInHtml and addLinksInText accept an optional parameter to exclude linking to a specific definition.

const natural = require('natural');
const definition_linker = require('definition-linker')({
    stem: function stem(text) {
        // keepStops=true
        return natural.PorterStemmerFr.tokenizeAndStem(text, true).join(' ');
    }
});
 
definition_linker.createIndex();
 
definition_linker.addToIndex('node.js', '#node.js');
definition_linker.addToIndex('logiciel libre', '#logiciel-libre');
// etc.
 
const html1 = definition_linker.addLinksInHtml('Node.js est un logiciel libre', '#node.js');
 
const html2 = definition_linker.addLinksInHtml('Il existe de nombreux logiciels libres dont Node.js', '#logiciel-libre');

Nolink

It is possible to disable linking on some terms in the HTML by setting a "nolink" class:

const natural = require('natural');
const definition_linker = require('definition-linker')({
    stem: function stem(text) {
        // keepStops=true
        return natural.PorterStemmerFr.tokenizeAndStem(text, true).join(' ');
    }
});
 
definition_linker.createIndex();
 
definition_linker.addToIndex('node.js', '#node.js');
definition_linker.addToIndex('logiciel libre, '#logiciel-libre');
// etc.
 
const html3 = definition_linker.addLinksInHtml('Node.js est un <span class="nolink">logiciel libre</span>', '#node.js');

Development

It is possible to disable linking on some terms in the HTML by setting a "nolink" class:

export DEBUG='definition-linker'
npm test
