Eclipse IDE Editor Configuration Preferences

12 Apr

Eclipse can be setup to display code in an infinite number of ways. The following settings are how I like to configure the Eclipse IDE.

  • Spaces instead of tabs
  • Show line numbers
  • Show whitespace characters
  • Show a print margin

These settings can be changed at: Window -> Preferences -> General -> Editors -> Text Editors

Click the “configure visibility” link next to the show white space setting to add fine tuning. I always uncheck the the trailing carriage return and line feed boxes and increase the opaqueness.

Eclipse IDE – Indent and Beautify Apex Code

23 Dec

Eclipse doesn’t currently offer an option to beautify Apex code. Sorry about the trick title. However, I will describe techniques that will help you clean up your code’s indentation. Neither way is perfect, but they have helped me make my code more readable. In the meantime, vote up this idea for the enhancement.

Method 1: Developer Console

This technique uses the Developer Console to indent the source code. Then we refresh the code in Eclipse.

  • In the Developer Console
  • Open the class
  • Select all or just a section of code to indent
  • Press Shift + Tab
  • Save
  • In Eclipse
  • Right-click the class name
  • Select ‘’ -> ‘Refresh from Server’

Method 2: NotePad++ with the TextFX plugin

If you use Windows and don’t have NotePad++, download it now. It is an incredibly helpful free text utility. The plugin called TextFX has a feature to reindent code. The menu for TextFX plugin appears after it is installed. The plugin feature is intended for C++, but it also works well for APEX. I think this does a better job than the Developer Console.

  • Copy your code from Eclipse
  • Paste it into a Notepad++ window
  • Select ‘TextFX’ -> ‘TextFX Edit’ -> ‘Reindent C++ code’
  • Copy the indented code
  • Paste it back into Eclipse

The function will indent with tabs by default. It can be changed to use spaces by selecting ‘Settings’ -> ‘Preferences…’ -> ‘Tab Settings’.

Bonus: Indent Visualforce

This can be done in the Eclipse IDE. However, be careful because it will sometimes remove an end bracket when it is in a style attribute. For example: <div style=”width: {!MyWidth}”> will end up like <div style=”width: {!MyWidth”>

  • Select the section of Visualforce code that you want to indent
  • Press Ctrl + Shift + F

Eclipse editor preferences control the number of spaces that Visualforce is indented. To change the spacing, select ‘Window’ -> ‘Preferences’. Expand ‘Web’ -> ‘HTML Files’ -> ‘Editor’.
