<h1>Showing full or compressed package names</h1>
<p>Package Explorer and Packages views can show full or compressed package names.</p>
<p>To show full package names:</p>
<ul>
<li>Clear the <span class="control"> Compress all package name segments, except the final segment</span> checkbox
on the
<a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.jdt.ui.preferences.AppearancePreferencePage)")'>
<img src="PLUGINS_ROOT/org.eclipse.help/command_link.png">
<span class="control">Java &gt; Appearance</span></a> preference page.</li>
</ul>
To show compressed package names:
<ul>
<li>
<p>Check the <span class="control">Compress all package name segments, except the final segment</span>
checkbox on the
<a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.jdt.ui.preferences.AppearancePreferencePage)")'>
<img src="PLUGINS_ROOT/org.eclipse.help/command_link.png">
<span class="control">Java &gt; Appearance</span></a> preference page.</p>
<p>Compression patterns control how many characters of each package name
segment are displayed. The last segment of a package name is
always displayed.</p>
<p>A compression pattern of &quot;.&quot; indicates that only the
separating periods are shown to represent a segment. A digit (n)
in a compression pattern represents the first n characters of a package name segment.
Examples are the best way to understand compression patterns. The
package <span class="control">org.eclipse.jdt </span>would be displayed
as follows using the example compression patterns:</p>
<p> <span class="control">.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span>..jdt</p>
<p><span class="control">0&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span>jdt</p>
<p><span class="control">2~&nbsp;&nbsp;&nbsp;&nbsp; </span>or~.ec~.jdt</p>
<p> <span class="control">3~&nbsp;&nbsp;&nbsp;&nbsp; </span>org.ecl~.jdt</p>
</li>
</ul>
