(1) Make sure there is a Copyright notice on all visible files. (2) Make sure all years in which the file has been modified are listed. (3) Make sure the format is consistent, i.e. separate consecutive years with a dash, not a comma. When Stephane changed starteam.html it has been 2001 in France but 2002 in Australia - does that mean we add 2002 to the Copyright line or not? ;-) git-svn-id: https://svn.apache.org/repos/asf/ant/core/trunk@270652 13f79535-47bb-0310-9956-ffa450edef68

<h2><a name="foreach">Pathconvert</a></h2>
|
|
<h3>Description</h3>
|
|
<p>Converts a nested path, path reference, or fileset reference to the form usable on a
|
|
specified platform
|
|
and stores the result in a given property. This operation is useful when script files
|
|
(batch files or shell scripts) must be generated my the build system and they contain
|
|
path information that must be properly formatted for the target architecture, not the
|
|
architecture on which the build is running, or when you need to create a list of files
|
|
separated by a given character, like a comma or a space.
|
|
</p>
|
|
<p>Prefix maps can be specified to map Windows drive letters to Unix paths and vice
|
|
versa.</p>
|
|
|
|

<h3>Parameters specified as nested elements</h3>
|
|
<h4>map</h4>
|
|
<p>Specifies the mapping of path prefixes between Unix and Windows.</p>
|
|
<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">from</td>
|
|
<td valign="top">The prefix to match. Note that this value is case insensitive when
|
|
the build is running on a windows platform and case sensitive when running on a
|
|
Unix platform.</td>
|
|
<td valign="top" align="center">Yes</td>
|
|
</tr>
|
|
<tr>
|
|
<td valign="top">to</td>
|
|
<td valign="top">The replacement text to use when <i>from</i> is matched.</td>
|
|
<td valign="top" align="center">Yes</td>
|
|
</tr>
|
|
</table>
|
|
|
|
<p>Each map element specifies a single replacement map to be applied to the elements of
|
|
the path being processed. If no map entries are specified, then no path prefix mapping
|
|
is performed.
|
|
</p>
|
|
<p><i>Note that the map elements are applied in the order specified and the only the first
|
|
matching map element is applied. So, the ordering of your map elements can be important
|
|
if any <TT>from</tt> values are prefixes of other <tt>from</tt> values.</i>
|
|
</p>
|
|
<h4>path</h4>
|
|
<p>If a path reference is not supplied using the <i>refid</i> attribute, then a
|
|
nested path element must be supplied. See
|
|
<a href="../using.html#path">Path-like Structures</a> for details.</p>
|
|
|
|
<h3>Examples</h3>
|
|
<p>In the examples below, assume that the property <b>wl.home</b> has the value
|
|
<tt>d:\weblogic</tt> on Windows and <tt>/weblogic</tt> on Unix.</p>
|
|
<h4>Example 1</h4>
|
|
<pre>
|
|
<path id="wl.path">
|
|
<pathelement location="${wl.home}/lib/weblogicaux.jar" />
|
|
<pathelement location="${wl.home}/classes" />
|
|
<pathelement location="${wl.home}/mssqlserver4/classes" />
|
|
<pathelement location="c:\winnt\System32" />
|
|
</path>
|
|
|
|
<pathconvert targetos="unix" property="newpath" refid="wl.path"/>
|
|
</pre>
|
|
<p>Assuming wl.property has the value "d:\weblogic", will generate the path shown below
|
|
and store it in the property named <tt>newpath</tt>
|
|
</p>
|
|
<pre>
|
|
/weblogic/lib/weblogicaux.jar:/weblogic/classes:/weblogic/mssqlserver4/classes:/WINNT/SYSTEM32
|
|
</pre>
|
|
Note that the drive letters have been removed. This is the default behavior when no map
|
|
elements have been specified.
|
|
|
|
<h4>Example 2</h4>
|
|
<pre>
|
|
|
|
<pathconvert targetos="unix" property="newpath" >
|
|
<path id="wl.path">
|
|
<pathelement location="${wl.home}/lib/weblogicaux.jar" />
|
|
<pathelement location="${wl.home}/classes" />
|
|
<pathelement location="${wl.home}/mssqlserver4/classes" />
|
|
<pathelement location="c:\winnt\System32" />
|
|
</path>
|
|
</pathconvert>
|
|
</pre>
|
|
This generates the exact same path as the previous example. It demonstrates the use of
|
|
a nested path element.
|
|
<h4>Example 3</h4>
|
|
<pre>
|
|
<pathconvert targetos="unix" property="newpath" refid="wl.path">
|
|
<map from="d:" to="/foo"/>
|
|
<map from="c:" to="/bar"/>
|
|
</pathconvert>
|
|
</pre>
|
|
<p>This example specifies two map entries that will convert path elements that start with
|
|
<tt>c:</tt> to <TT>/dos</tt> and <tt>d:</tt> to <TT>/</tt>. The resulting path is shown
|
|
below.</p>
|
|
<pre>
|
|
/weblogic/lib/weblogicaux.jar:/weblogic/classes:/weblogic/mssqlserver4/classes:/dos/WINNT/SYSTEM32
|
|
</pre>
|
|
<h4>Example 4</h4>
|
|
<pre>
|
|
<pathconvert targetos="windows" property="newpath" >
|
|
<path id="wl.path">
|
|
<pathelement location="${wl.home}/lib/weblogicaux.jar" />
|
|
<pathelement location="${wl.home}/classes" />
|
|
<pathelement location="${wl.home}/mssqlserver4/classes" />
|
|
<pathelement location="/dos/winnt/System32" />
|
|
</path>
|
|
<map from="/dos" to="c:\"/>
|
|
<map from="/" to="d:\"/>
|
|
</pathconvert>
|
|
</pre>
|
|
<p>This example, similar to the one above but targetting windows, specifies two map
|
|
entries that will convert path elements that start with
|
|
<tt>/dos</tt> to <TT>c:\</tt> and <tt>/</tt> to <TT>d:\</tt>. Note that the order of the
|
|
map elements was important here since <tt>/</tt> is a prefix of <tt>/dos</tt>.
|
|
The resulting path is shown below.</p>
|
|
<pre>
|
|
d:\weblogic\lib\weblogicaux.jar;d:\weblogic\classes;d:\weblogic\mssqlserver4\classes;c:\WINNT\SYSTEM32
|
|
</pre>
|
|
<h4>Example 5</h4>
|
|
<pre>
|
|
<fileset dir="${src.dir}" id="src.files">
|
|
<include name="**/*.java"/>
|
|
</fileset>
|
|
|
|
<pathconvert pathsep="," property="javafiles" refid="src.files"/>
|
|
</pre>
|
|
<p>This example takes the set of files determined by the fileset (all files ending
|
|
in <tt>.java</tt>), joins them together separated by commas, and places the resulting
|
|
list into the property <tt>javafiles</tt>. The directory separator is not specified, so
|
|
it defaults to the appropriate character for the current platform. Such a list could
|
|
then be used in another task, like <tt>javadoc</tt>, that requires a comma separated
|
|
list of files.
