How to Use TEX

To use TEX in your project, follow these simple steps:

1. Link TEX to your HTML:

<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/gh/marcellov7/tex@main/src/tex.min.css">
<script src="https://cdn.jsdelivr.net/gh/marcellov7/tex@main/src/tex.min.js"></script>

3. Add HTML elements where you want to display the text editors:

<div id="editor">Hello</div>
<!--or-->
<textarea id="editor">Hello</textarea>

Usage

Initialization

To initialize TEX, use the tex.init() method, passing in an object with the desired settings. Here's how you can do it:

const tex = window.tex;

tex.init({
    element: document.getElementById("editor"),
    buttons: ['bold', 'italic', 'underline', 'textColor', 'heading1', 'heading2', 'paragraph', 'removeFormat', 'olist', 'ulist', 'code', 'line', 'link', 'image', 'html'],
    onChange: (content) => {
        console.log("Editor :", content);
    }
});

API

// ES6
import tex from 'tex'
// or
import { exec, init, destroy, getContent } from 'tex'

Parameters

• element: The HTML element (either <textarea> or <div>) to be converted into a text editor.
• buttons: An array of buttons to be displayed in the editor toolbar.
• plugins: An array of plugins.
• paragraphSeparator : 'p', // optional, default = 'div'
• cssStyle: false | true, // Outputs instead of
• theme: 'dark' | default (light),
• onChange: A callback function to be executed when the content of the editor changes.

Get Content

tex.getContent(document.getElementById("editor"));

Plugins

Plugin demo: https://codepen.io/marcellov7/pen/poYqEMV

var pluginImageUpload = {
    name: 'pluginImageUpload',
    icon: '-↑-',
    title: 'Image Upload',
    result: function(res) {
        //Example function to display an input and upload the image.
    }
};

Initialise the button in the position you want and the plugin, like this:

 tex.init({
    element: document.getElementById("editor"),
    buttons: ['pluginImageUpload', 'bold', 'fontSize', 'bold', 'italic'],
    plugins: [pluginImageUpload],
    onChange: () => {
    }
});

Styles

For example: If you want to change the height of the editor after the DOM has been initialized, you can do so by targeting the ".tex-content" class and adjusting the height property in your CSS file.

.tex-content {
    height: 400px;
}
