Mergely

https://mergely.com

Mergely is a JavaScript component for differencing and merging files interactively in a browser (diff/merge), providing rich API that enables you to easily integrate Mergely into your existing web application. It is suitable for comparing text files online, for example, .txt, .html, .xml, .c, .cpp, .java, etc.

Mergely has a JavaScript implementation of the Longest Common Subsequence (LCS) diff algorithm, and a customizable markup engine.

Installation

Installation via webpack

The recommended way to install mergely and its dependencies is to use a Node package manager (npm or yarn) and webpack.

It is highly recommended that you start by cloning mergely-webpack. The webpack has everything that you need to get started.

Angular 6.1.1

You can also use mergely within angular. You can start by cloning mergely-angular.

Installation via .tgz

Unpack mergely.tgz into a folder, for example, ./lib, and add the following to the <head> of your target HTML source file.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.32.0/codemirror.min.js"></script>
<link rel="stylesheet" media="all" href="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.32.0/codemirror.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.32.0/addon/search/searchcursor.min.js"></script>
<script src="lib/mergely/lib/mergely.js" type="text/javascript"></script>
<link rel="stylesheet" media="all" href="lib/mergely/lib/mergely.css" />

Create a div for the editor in <body>.

This example uses a style that provides 8px padding (mergely-full-screen-8):

<div class="mergely-full-screen-8">
  <div class="mergely-resizer">
    <div id="mergely"></div>
  </div>
</div>

Then initialize mergely, setting options as required.

$(document).ready(function () {
    $('#mergely').mergely();
});

Synchronous content initialization

The following example can be used to set the lhs and rhs editors synchronously (that is, when their contents are already known):

$(document).ready(function () {
    // set editor content
    $('#mergely').mergely({
        lhs: function(setValue) {
            setValue('the quick red fox\njumped over the hairy dog');
        },
        rhs: function(setValue) {
            setValue('the quick brown fox\njumped over the lazy dog');
        }
    });
});

Asynchronous initialization

If the editor contents are retrieved asynchronously (recommended), then retrieve the editor contents and set them:

$(document).ready(function () {
    // initialize mergely
    $('#mergely').mergely();
    
    // get async lhsResponse, then set lhs value
    $('#mergely').mergely('lhs', lhsResponse);
    
    // get async rhsResponse, then set rhs value
    $('#mergely').mergely('rhs', rhsResponse);
});

Options

Option Type Default value Description
autoresize boolean true Enables/disables the auto-resizing of the editor.
autoupdate boolean true Enables/disables the auto-updating of the editor when changes are made.
bgcolor string #eeeeee The background color that mergely fills the margin canvas with.
change_timeout number 500 The timeout, after a text change, before Mergely calculates a diff. Only used when readonly is enabled.
cmsettings object {mode: 'text/plain', readOnly: false} CodeMirror settings (see CodeMirror) that are combined with lhs_cmsettings and rhs_cmsettings.
editor_width string 400px Starting width.
editor_height string 400px Starting height.
fadein string fast A jQuery fadein value to enable the editor to fade in. Set to empty string to disable.
