<h2><a name="unpack">GUnzip/BUnzip2</a></h2>
|
|
<h3>Description</h3>
|
|
<p>Expands a resource packed using GZip or BZip2.</p>
|
|
|
|
<p>If <i>dest</i> is a directory the name of the destination file is
|
|
the same as <i>src</i> (with the ".gz" or ".bz2"
|
|
extension removed if present). If <i>dest</i> is omitted, the parent
|
|
dir of <i>src</i> is taken. The file is only expanded if the source
|
|
resource is newer than the destination file, or when the destination file
|
|
does not exist.</p>
|
|
|
|
<h3>Parameters</h3>
|
|
<table border="1" cellpadding="2" cellspacing="0">
|

<td valign="top"><b>Attribute</b></td>
|
|
<td valign="top"><b>Description</b></td>

<td align="center" valign="top"><b>Required</b></td>

</tr>
|
|
<tr>
|
|
<td valign="top">src</td>
|
|
<td valign="top">the file to expand.</td>
|
|
<td align="center" valign="top">Yes, or a nested resource collection.</td>
|

</tr>
|
|
<tr>
|
|
<td valign="top">dest</td>
|
|
<td valign="top">the destination file or directory.</td>
|
|
<td align="center" valign="top">No</td>
|
|
</tr>
|
|
</table>
|
|
<h3>Parameters specified as nested elements</h3>
|
|
|
|
<h4>any <a href="../CoreTypes/resources.html">resource</a> or single element
|
|
resource collection</h4>
|
|
|
|
<p>The specified resource will be used as src.</p>
|

<h3>Examples</h3>
|
|
<blockquote><pre>
|
|
<gunzip src="test.tar.gz"/>
|
|
</pre></blockquote>
|
|
<p>expands <i>test.tar.gz</i> to <i>test.tar</i></p>
|
|
<blockquote><pre>
|
|
<bunzip2 src="test.tar.bz2"/>
|
|
</pre></blockquote>
|
|
<p>expands <i>test.tar.bz2</i> to <i>test.tar</i></p>
|
|
<blockquote><pre>
|
|
<gunzip src="test.tar.gz" dest="test2.tar"/>
|
|
</pre></blockquote>
|
|
<p>expands <i>test.tar.gz</i> to <i>test2.tar</i></p>
|
|
<blockquote><pre>
|
|
<gunzip src="test.tar.gz" dest="subdir"/>
|
|
</pre></blockquote>
|
|
<p>expands <i>test.tar.gz</i> to <i>subdir/test.tar</i> (assuming
|
|
subdir is a directory).</p>
|
|
<blockquote><pre>
|
|
<gunzip dest=".">
|
|
<url url="http://example.org/archive.tar.gz"/>
|
|
</gunzip>
|
|
</pre></blockquote>
|
|
<p>downloads <i>http://example.org/archive.tar.gz</i> and expands it
|
|
to <i>archive.tar</i> in the project's basedir on the fly.</p>
|
|

|
|
<pre>
|
|
<gunzip src="some-archive.gz" dest="some-dest-dir"/>
|
|
</pre>
|
|
|
|
is identical to
|
|
|
|
<pre>
|
|
<copy todir="some-dest-dir">
|
|
<gzipresource>
|
|
<file file="some-archive.gz"/>
|
|
</gzipresource>
|
|
<mapper type="glob" from="*.gz" to="*"/>
|
|
</copy>
|
|
</pre>
|
|
|
|
<p>The same is also true for <code><bunzip2></code> and
|
|
<code><bzip2resource></code>. <code><copy></code> offers
|
|
additional features like <a
|
|
href="../CoreTypes/filterchain.html">filtering files</a> on the fly,
|
|
allowing a file to be mapped to multiple destinations, preserving the
|
|
last modified time or a configurable file system timestamp
|
|
granularity.</p>
