| <h2><a name="pack">Compressing Tasks</a></h2> |
| <h3>Description</h3> |
| |
| <p>For each of the supported compression formats there is a |
| correspondig task that compresses a resource. These tasks are not |
| based on |
| their <a href="http://ant.apache.org/manual/CoreTasks/pack.html">core |
| cousin tasks</a> but provide similar functionality.</p> |
| |
| <h3>Parameters</h3> |
| <table border="1" cellpadding="2" cellspacing="0"> |
| <tr> |
| <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 resource to compress.</td> |
| <td align="center" valign="top" rowspan="2">Yes, or a nested |
| resource collection or a nested archiving task.</td> |
| </tr> |
| <tr> |
| <td valign="top">srcfile</td> |
| <td valign="top">the file to compress.</td> |
| </tr> |
| <tr> |
| <td valign="top">dest</td> |
| <td valign="top">the destination resource to create.</td> |
| <td align="center" valign="top" rowspan="2">Exactly one of the |
| two or a nested dest element.</td> |
| </tr> |
| <tr> |
| <td valign="top">destfile</td> |
| <td valign="top">the destination file to create.</td> |
| </tr> |
| </table> |
| |
| <h3>Parameters specified as nested elements</h3> |
| |
| <h4>any <a href="http://ant.apache.org/manual/CoreTypes/resources.html">resource</a> |
| or single element resource collection</h4> |
| |
| <p>The specified resource will be used as src.</p> |
| |
| <h4>any <a href="archive.html">archiving task</a></h4> |
| |
| <p>The task's output will be used as src.</p> |
| |
| <p>You must not specify the archiving task's dest attribute or |
| nested element.</p> |
| |
| <h4>dest</h4> |
| |
| <p>Accepts |
| any <a href="http://ant.apache.org/manual/CoreTypes/resources.html">resource</a> |
| or single element resource collection as nested element.</p> |

| <p>The specified resource will be used as dest.</p> |
| |
| <h3><a name="bzip2">BZip2</a></h3> |
| |
| <p>Is an <a href="#pack">compressing task</a> that uses the BZIP2 |
| compression algorithm.</p> |
| |
| <h3><a name="gzip">GZip</a></h3> |
| |
| <p>Is an <a href="#pack">compressing task</a> that uses the GZIP |

| <h3>Examples</h3> |
| <pre> |
| <cmp:gzip src="test.tar" dest="test.tar.gz" |
| xmlns:cmp="antlib:org.apache.ant.compress"/> |
| </pre> |
| |

| <cmp:bzip2 src="test.tar" destfile="test.tar.bz2" |
| xmlns:cmp="antlib:org.apache.ant.compress"/> |
| </pre> |
| <pre> |
| <cmp:gzip destfile="archive.tar.gz" xmlns:cmp="antlib:org.apache.ant.compress"> |
| <url url="http://example.org/archive.tar"/> |
| </cmp:gzip> |
| </pre> |
| <p>downloads <i>http://example.org/archive.tar</i> and compresses it |
| to <i>archive.tar.gz</i> in the project's basedir on the fly.</p> |
| |
| <pre> |
| <cmp:gzip xmlns:cmp="antlib:org.apache.ant.compress"> |
| <cmp:tar> |
| <fileset dir="src"/> |
| </cmp:tar> |
| <dest> |
| <file file="src.tar.gz"/> |
| </dest> |
| </cmp:gzip> |
| </pre> |
| <p>Creates a tar archive of all files in the <i>src</i> directory, |
| compresses it using GZIP and stores it in the |
| file <i>src.tar.gz</i> in the project's basedir.</p> |
