# OmniEditor

*Ready-made ScalaFX IDE for custom languages*

## Introduction

OmniEditor is a ScalaFX library providing a ready-made, user-friendly IDE for custom programming languages as well as an independent code editor with syntax highlighting.

First of all, it supports the basic interactive activities provided by a document workspace:

* New
 * Open
 * Save
 * Save as
 * Undo
 * Redo
 * Cut
 * Copy
 * Paste
 * Settings
 * Help
 * About

In addition to this, OmniEditor enables *the execution of interpreters/compilers* on the code written in the text editor, allowing the user to cancel the process via the *Stop* button in the user interface (for example, in case of infinite loops).

Finally, for Java/JavaFX development (without Scala), the 2.x series is still available on Hephaestus, its Gradle/Maven repository.

## Core classes

### OmniEditor

The *OmniEditor* class provides a customizable IDE application packaged as a Scala class.

To run it, just add a few lines to the *start* method of your JavaFX/ScalaFX application subclass:

```scala
val omniEditor = new OmniEditor(appStrategy)
omniEditor.start(primaryStage)
```

where *appStrategy* is an instance of a class implementing the *AppStrategy* interface defined by the library, and *primaryStage* is the parameter of the *start* method in your JavaFX/ScalaFX application.

For further information, please refer to the Scaladoc documentation.

### StyledCodeEditor

Stemming from the "JavaKeywords" example provided by [RichTextFX](https://github.com/TomasMikula/RichTextFX), this class is the core of OmniEditor and creates a code editor easily customizable via CSS.

In particular:

* you can define a chain of *regex patterns*, each describing which CSS class should be applied to its matching text

* a shortcut method is defined to apply a CSS class to a set of tokens (especially keywords)

* it supports *indented new lines*, to keep each new line aligned with the previous one whenever the user presses ENTER

* it supports *dynamic tabs* - the insertion of a given number of space characters in lieu of \\t whenever the user presses TAB.

Please, refer to its Scaladoc for more details.

## Requirements

OmniEditor requires:

* Java 8 Update 91 or later compatible

* Scala 2.11.8 or later compatible

## Download

For further information about downloading or referencing OmniEditor via Gradle or Maven, please visit [its page](https://bintray.com/giancosta86/Hephaestus/OmniEditor) on Hephaestus, its Gradle/Maven repository.

## OmniEditor in action

The very first open source application employing OmniEditor is [Chronos IDE](https://github.com/giancosta86/Chronos-IDE), for the [Chronos programming language](https://github.com/giancosta86/Chronos).

## Special thanks

* OmniEditor is based on [RichTextFX](https://github.com/TomasMikula/RichTextFX), and was created starting from its brilliant "JavaKeywords" demo

* OmniEditor also employs [Helios-fx](https://github.com/giancosta86/Helios-fx), an open source ScalaFX library of shared utilities

* The UI icons are taken from the elegant [Kids Icons](http://www.iconarchive.com/show/kids-icons-icons-by-everaldo.1.html) set, by [Everaldo Coelho](http://www.everaldo.com/).
