link-injection

Parse text for keywords and replace with links for documentation

How it works

link-injection parses arbitrary text and replaces all keywords with an anchor link to the keyword's reference. Excellent for creating hyperlinks in documentation to other parts of the documentation and who knows what else. What is supported:

  • Can parse plain text, or HTML -- will not create an anchor inside of another anchor
  • Full word matching -- if Array is a keyword, it will not transpose Float32Array into an anchor

Installing

  • npm install link-injection

Methods

  • parse( text, map, options ) Parses string text replacing instances of map's keys with an anchor with an href to the key's value.

Options

  • caseSensitive : Whether or not the keyword match should be case-sensitive. (default: true)

Usage

var
  inject = require( 'link-inject' ),
  html = '<div>Modern browsers are now implementing a Float32Array type, ' +
    'which is a typed array version of an Array, except it only holds 32-bit ' +
    'floating point numbers. The <a href="#Float32Array">Float32Array</a> is ' +
    'frequently used in 3D WebGL applications and audio processing.</div>';
  // Using local links, but can be anything -- the keys' values are put into the href attribute
  map = {
    'Array' : '#Array',
    'Float32Array' : '#Float32Array'
  };

var output = inject.parse( html, map );
console.log( output );

Outputs (spacing added for viewing):

<div>
Modern browsers are now implementing a <a href="#Float32Array" title="Float32Array">Float32Array</a>
type, which is a typed array version of an <a href="#Array" title="Array">Array</a>, except it
only holds 32-bit floating point numbers. The <a href="#Float32Array">Float32Array</a>
is frequently used in 3D WebGL applications and audio processing.
</div>

Development

Run make in the project root to build the coffee into JavaScript. Run npm test from project root -- requires mocha to be installed globally
