=== Show number lines ===
* Go to '''Window &rarr; Preferences &rarr; General &rarr; Editors &rarr; Text editors''', check '''Show line numbers'''.

=== Use monospace fonts for watch points, registers... ===
Sick of debugger watch/register value in ''proportional'' font?
* Go to '''Window &rarr; Preferences &rarr; General &rarr; Appearance &rarr; Colors and Fonts''', select '''Debug''', and double click '''Variable text font'''.
* Select your favorite monospace font (for instance <code>Consolas 9</code>).

=== Keep Debug tab minimized ===
When in debug mode, Eclipse will keep displaying the ''Debug'' tab even if you minimize it. To prevent this
* Go to '''Window &rarr; Preferences &rarr; Run/Debug'''.
* Uncheck '''Activate the workbench when a breakpoint is hit''' and '''Activate the debug view when a breakpoint is hit'''.

=== Miscellaneous debugging tips ===
* If possible, disable compiler optimization (use <code>-O0</code>), or some symbols will not be available to the debugger (because in register).
* To step into disassembled code, click on button [[File:Eclipse-instr stepping button.PNG]] '''Instruction Stepping Mode''' on ''Debug'' toolbar.

=== Miscellaneous ===
* Console windows truncates part of the program output &rarr; right click in console Windows &rarr; Preferences...

* Install KeyTool Plugin:
** Go to http://keytool.sourceforge.net/, '''installing''', write down the URL (typ. <tt>http://keytool.sourceforge.net/update</tt>)
** In Eclipse, ''Help'' &rarr; ''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).

== 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'' &rarr; ''Java'' &rarr; ''Code Style'' &rarr; ''Formatter''.

Frequent shortcuts:
* {{kb|Ctrl-I}} &mdash; correct indentation
* {{kb|Ctrl-Shift-F}} &mdash; Format

* 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:
# Go to Eclipse Formatter preferences (''Eclipse preferences'' &rarr; ''Java'' &rarr; ''Code Style'' &rarr; ''Formatter'')
# Configure the formatter as desired (possibly creating a new profile)
# Click on ''Configure Project Specific Settings...''
# Select a project, and ''Enable project specific settings''
# Go in the selected project workspace, and copy the file <tt>.settings/org.eclipse.jdt.core.prefs</tt> to some location of your choice (say <tt>~/etc</tt>)
# Now to format a source tree <tt>./src</tt>, do:

<source lang="bash">
eclipse -nosplash \
-application org.eclipse.jdt.core.JavaCodeFormatter \
-verbose \
-config ~/etc/org.eclipse.jdt.core.prefs \
./src
</source>

Plugins

  • Jalopy 0.2.6 (Obsolete - now in Eclipse)
  • TabNavigator 1.1.0
  • Readonly Decorator (probably not needed today)

Tips

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

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 value in proportional font?

  • 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).

Keep Debug tab minimized

When in debug mode, Eclipse will keep displaying the Debug tab even if you minimize it. To prevent this

  • Go to Window → Preferences → Run/Debug.
  • Uncheck Activate the workbench when a breakpoint is hit and Activate the debug view when a breakpoint is hit.

Miscellaneous debugging tips

  • If possible, disable compiler optimization (use -O0), or some symbols will not be available to the debugger (because in register).
  • To step into disassembled code, click on button Eclipse-instr stepping button.PNG Instruction Stepping Mode on Debug toolbar.

Miscellaneous

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

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).

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

  1. Go to Eclipse Formatter preferences (Eclipse preferences → Java → Code Style → Formatter)
  2. Configure the formatter as desired (possibly creating a new profile)

  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 \
