marklib

A simple and fast zero-dependencies-library to transform text-selections into serializable markings.

Demo

Install

marklib can be installed with npm or bower.

npm install --save-dev marklib

bower install marklib --save

Usage

The API is quite limited right now, and supports only rendering either a range or a serialized result.

Render by selection

// obtain a selection from document
var selection = document.getSelection();

// create a new rendering based on the current document
var renderer = new Marklib.Rendering(document)
renderer.setId('myRenderId') // if an ID is not provided, a autogenerated one will be used

// renders the given selection and returns a serializable result.
var result = renderer.renderWithRange(selection.getRangeAt(0));

Constructor Arguments

• 1. HTMLDocument document -> the document instance used
• 2. string [cssClass], optional -> a class that is applied on each marking container (for styling)
• 3. HTMLElement [context], optional -> the context used to serialize / deserialize the rendering, if not given the document instance

Render by serialized result

A Serialized results consist of 2 strings (start end end) in the following form

'body>section;0;1'`
-▲------------▲-▲ 

• ▲ The first part defines a css-selector (queryable with document.querySelector).
• ▲ The second part defines the text-node inside the given selector
• ▲ The third part defines the string-offset inside this text-node

Example

 // This is the result we get from the renderWithRange method
 
 var result = {
    startContainerPath: 'body>section;0',
    endContainerPath: 'body>section;1',
    startOffset: 2,
    endOffset: 5
 }

 var rendering = new Marklib.Rendering(document);
 
 rendering.renderWithResult(result);

• Annotations
• Collaboration tools
• Inline-Commenting (I actually started a project that will do something like this: https://github.com/BowlingX/commentp)
