Tips

Wonder why it is called Eclipse? Because important stuff are hidden.

Miscellaneous

• Console windows truncates part of the program output → right click in console Windows → Preferences...

• Install KeyTool Plugin:
  • Go to http://keytool.sourceforge.net/, installing, write down the URL (typ. http://keytool.sourceforge.net/update)
  • In Eclipse, Help → Install New Software...
  • Type in the URL in Work with:, click Add, type in a local plugin name, install and then restart Eclipse.

Note: Don't forget to setup the proxy settings if needed (since Eclipse 3.6.0 Helios the settings of IE are used by default).

Show number lines

• Go to Window → Preferences → General → Editors → Text Editors, check Show line numbers.

Use monospace fonts for watch points, registers...

Sick of debugger watch/register values in proportional fonts?

• Go to Window → Preferences → General → Appearance → Colors and Fonts, select Debug, and double click Variable text font.
• Select your favorite monospace font (for instance Consolas 9).

Formatting

Using Eclipse

Automatic code indentation and source formatting is now directly embedded in Eclipse. There is no need for an external tool like Jalopy or so.

Find it at Eclipse preferences → Java → Code Style → Formatter.

Frequent shortcuts:

• Ctrl-I — correct indentation
• Ctrl-Shift-F — Format

Using Eclipse to format code:

• http://blogs.operationaldynamics.com/andrew/software/java-gnome/eclipse-code-format-from-command-line
• http://www.peterfriese.de/formatting-your-code-using-the-eclipse-code-formatter/

A solution:

1. Go to Eclipse Formatter preferences (Eclipse preferences → Java → Code Style → Formatter)
2. Configure the formatter as desired (possibly creating a new profile)
3. Click on Configure Project Specific Settings...
4. Select a project, and Enable project specific settings
5. Go in the selected project workspace, and copy the file .settings/org.eclipse.jdt.core.prefs to some location of your choice (say ~/etc)
6. Now to format a source tree ./src, do:

eclipse -nosplash \
    -application org.eclipse.jdt.core.JavaCodeFormatter \
    -verbose \
    -config ~/etc/org.eclipse.jdt.core.prefs \
    ./src
