Introduction

EGL editor is base on eclipse to provide specialized features for editing EGL code. Associated with the editor is a EGL-specific Outline view, which shows the structure of the active EGL Part. It is updated as the user edits the EGL file. The EGL editor includes the following features:

  • Syntax highlighting
  • Content/code assist
  • Code formatting
  • Import assistance(Organize import)
  • Quick fix
  • Integrated debugging features

In this blog I will introduce some features to improve the EGL development efficiency

  1. Use Content Assist to improve development efficiency
  2. Quick fix/Quick Assist
  3. Navigation between EGL parts
  4. Vertical ruler

Use Content Assist to improve development efficiency

Content assist helps you to quickly define variable, function or finish a line of code in the EGL editor. The content assist is context sensitive, which means that the proposals listed in the dialog is different with the cursor position changing. In the EGL editor press Ctrl + Space or Alt + “/”(Can be configured) on to trigger the content assist.This will open a list of available code completions.

Three types of content assist proposals in EGL

  1. Keyword Proposals:This proposal type only provides EGL Keywords which can be used at the current cursor position.
  2. Reference Proposals:This proposal type provides proposals like variables defined in the context,System type,library,functions which can be used at the current cursor position.
  3. Template Proposals:Template proposal type provide predefined code snippet,like function definition code, externaltype definition code etc.

How to configure content assist

  1. Open configuration dialog Window>Preferences>EGL>Editor>Content Assist
  2. Make sure auto activation checkbox was selected.
  3. Expend Content assist node and select Advanced configure page.
  4. Choose those Proposal kinds in your default proposal list(The first proposal list when content assist was invoked)
  5. Configure the order of proposal kinds you as you want.
    Content Assist Configuration

The content assist dialog

When Content Assist dialog displayed, you can use content assist hotkey to display specific proposal type.
Use Content Assist

How to use content assist

Define a variable

Take defining a checkbox type variable in a RUI Handler as a example.

  1. Type the variable name you want
  2. Invoke Content assist
  3. The content assist will list all proposals, and you can type characters to filter the result.
    Define a variable

Initial field value for complex types

Take a checkbox type variable as example. In the handler file, currently has a variable defined as following,
acheckbox CheckBox{};

  1. Now we want to initialize the width value of the check box.
  2. Invoke Content assist in “{}”.
  3. Type “w” to filter the result(You can type “i” again to filter result,if you want)
  4. Select “width” and press “enter”,the “width = “ will be inserted into EGL editor.
  5. Invoke Content Assist after “=”, “” will be inserted and you could input the value you want.
    Initialize Complex type

Use template proposals to define part

Use template to define function

Quick fix/Quick Assist

Create callback functions

Create delegate functions

Navigation between EGL parts

Open part dialog

Navigate between the EGL parts

Vertical ruler

Source folding

Add bookmark & tasks
