Developing EGL applications
Enterprise Generation Language (EGL) is a programming language that you can use to focus on business problems instead of software technologies. Within the Rational® development environment, you can use EGL wizards and other tools to write complex applications with minimal effort.
EGL Programmer's Guide
The EGL Programmer's Guide covers using EGL within the Eclipse Integrated Development Environment (IDE), as well as some of the common programming tasks that EGL developers perform.
Overview of EGL Rich UI
Developing with the EGL Dojo widgets
The EGL Dojo widget library represents a set of commonly used widgets that extend the Rich UI widget library. These widgets are available on the palette in the EGL Rich UI editor and can be used with the EGL widgets or your own custom widgets.
Preparing to use the EGL Dojo widgets
You can develop with the EGL Dojo widgets by using either a local or remote version of the Dojo Toolkit. In either case, you must specify the Dojo Toolkit provider on your EGL build path.
Accessing an updated remote Dojo Toolkit
To access a remote Dojo Toolkit that was updated after the product shipped, do as follows:

      - Developing with the EGL Dojo mobile widgets
        The EGL Dojo widget library represents a set of commonly used Dojox or mobile widgets that extend the Rich UI widget library. These widgets are available on the palette in the EGL Rich UI editor and can be used with the EGL Rich UI widgets or your own custom widgets.
      - Developing with the EGL Cordova library
        The EGL Cordova library is a set of RUI libraries and externalType parts to be used by EGL RUI projects. It allows the EGL mobile program to use the native mobile artifacts by leveraging Apache Cordova.
      - Introduction to the EGL Rich UI editor
        You can use the EGL Rich UI editor to modify a Rich UI handler and to preview the handler's runtime behavior.

    - Services: a top-level overview
      The topics in this section describe service-oriented architecture (SOA) and related technologies, EGL support for SOA, and service-related procedures, with an emphasis on service access. For details about deployment, see “Introduction to EGL generation and deployment” and “Add web-service deployment entries in the EGL deployment descriptor.”
    - Generating source code from UML models
      You can use transformations to create source code from a UML model. First you must create a transformation parameters file and then apply those parameters to a model.

  With code review, you can create configurations of coding rules for EGL source code. You can then run the configurations to check the source code for consistency with the rules.
- Responsive Design Support in IBD
  What is Responsive Design? Responsive design is an approach for creation of web pages that automatically scales its content and elements to match the screen size on which it is viewed. So, instead of designing multiple websites for different devices with variable screen sizes, we can design just one website that scales up or down automatically, to match the device it’s being viewed on.

Accessing an updated remote Dojo Toolkit

To access a remote Dojo Toolkit that was updated after the product shipped, do as follows:

Ensure that you have loaded the most recent version of the EGL Dojo runtime code from the provider of interest. An example is com.ibm.egl.rui.dojo.runtime.google_1.7.2. For keystroke details, see Accessing a remote Dojo Toolkit.
Create an EGL Rich UI project with a runtime name that matches the following convention:
```
com.ibm.egl.rui.dojo.runtime.<provider>_<version>
```
<provider>

Either google or aol.

<version>

The Toolkit version.

An example project name is com.ibm.egl.rui.dojo.runtime.google_1.7.3.
Change the EGL and Java™ build paths of the new project:
1. In the Project Explorer view, right-click the project and then click Properties. The Properties window opens.
2. Select the EGL Build Path properties page.
3. On the Projects tab, click Deselect All and then click the check box for the EGL Dojo widget project that is most recently supported; for example, com.ibm.egl.rui.dojo.widgets_2.1.1.
4. On the Order and Export tab, click the check box for the EGL Dojo widget project.
5. Select the Java Build Path properties page.
6. On the Source tab, click Remove as necessary to remove all entries.
7. Click OK.
Change the content of the WebContent folder:
1. Expand WebContent and remove all folders and files under that folder.
2. Replace the deleted content with the files and folders in the WebContent folder of the project mentioned in step 1; for example, the com.ibm.egl.rui.dojo.runtime.google_1.7.2 project.
3. In the new project, replace the previous version number with the new version number in each of the following two files:
  - WebContent/config/includeDojo.html
  - WebContent/README_<provider>_RUNTIME.html, where <provider> is GOOGLE or another value.
  Ensure that you search for all instances of the previous version number.
Change the EGL build path of the other Rich UI projects from which you want to reference the new runtime project. For keystroke details, see Editing the EGL build path.
