| <h2><a name="foreach">Pathconvert</a></h2> |
| <h3>Description</h3> |
| <p>Converts a nested <code><path></code> or reference to a Path, |
| FileSet, DirSet, or FileList into a path |
| form for a particular platform, and stores the result in a given property. |
| It can also be used when you need |
| to convert a Path, FileSet, or DirSet into a list, separated by a given |
| character, such as a comma or space, or, conversely, to convert a list |
| of files in a FileList into a path. |
| </p> |
| <p>Nested <code><map></code> elements can be specified to map Windows |
| drive letters to Unix paths, and vice-versa.</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">targetos</td> |
| <td valign="top"> |
| The target architecture. Must be one of 'unix', 'windows', |
| 'netware', 'tandem' or 'os/2'. |
| This is a shorthand mechanism for specifying both |
| <code>pathsep</code> and <code>dirsep</code> |
| according to the specified target architecture. |
| </td> |
| <td valign="top" align="center"> |
| Yes, unless <code>pathsep</code> and/or |
| <code>dirsep</code> are specified. |
| </td> |
| </tr> |
| <tr> |
| <td valign="top">dirsep</td> |
| <td valign="top"> |
| The character(s) to use as the directory separator in the |
| generated paths. |
| </td> |
| <td valign="top" align="center">No, defaults to current JVM <tt>File.separator</tt></td> |
| </tr> |
| <tr> |
| <td valign="top">pathsep</td> |
| <td valign="top"> |
| The character(s) to use as the path-element separator in the |
| generated paths. |
| </td> |
| <td valign="top" align="center">No, defaults to current JVM <tt>File.pathSeparator</tt></td> |
| </tr> |
| <tr> |
| <td valign="top">property</td> |

| <td valign="top" align="center">Yes</td> |
| </tr> |
| <tr> |
| <td valign="top">refid</td> |
| <td valign="top">What to convert, given as a |
| <a href="../using.html#references">reference</a> to a |
| <code><path></code>, <code><fileset></code>, |
| <code><dirset></code>, or <code><filelist></code> |
| defined elsewhere</td> |
| <td valign="top" align="center">No; if omitted, a nested |
| <code><path></code> element must be supplied.</td> |
| </tr> |
| <td valign="top">setonempty</td> |
| <td valign="top">Should the property be set, even if the result |
| is the empty string? |
| <td valign="top" align="center">No; default is "true". |

| </table> |
| <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 <code>from</code> 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><strong>Note</strong>: The map elements are applied in the order specified, |
| and only the first matching map element is applied. So, the ordering of |
| your map elements can be important, if any <code>from</code> values are |
| prefixes of other <code>from</code> values.</i> |
| </p> |
| <h4>path</h4> |
| <p>If the <code>refid</code> attribute is not specified, then a |
| nested <code><path></code> 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 <code>${wl.home}</code> property |
| has the value |
| <code>d:\weblogic</code>, and <code>${wl.home.unix}</code> has the value |
| <code>/weblogic</code>.</p> |
| <h4>Example 1</h4> |
| <pre> |
| <path id="wl.path"> |
| <pathelement location="${wl.home}/lib/weblogicaux.jar"/> |
| <pathelement location="${wl.home}/classes"/> |
| <pathelement location="${wl.home}/mssqlserver4/classes"/> |
| <pathelement location="c:\winnt\System32"/> |
| </path> |
| |
| <pathconvert targetos="unix" property="wl.path.unix" refid="wl.path"> |
| <map from="${wl.home}" to="${wl.home.unix}"/> |
| <map from="c:" to=""/> |
| </pathconvert> |
| </pre> |
| <p> will generate the path shown below |
| and store it in the property named <code>wl.path.unix</code>. |
| </p> |
| <pre> |
| /weblogic/lib/weblogicaux.jar:/weblogic/classes:/weblogic/mssqlserver4/classes:/WINNT/SYSTEM32 |
| </pre> |
| |
| <h4>Example 2</h4> |
| Given a FileList defined as: |
| <pre> |
| <filelist id="custom_tasks.jars" |
| dir="${env.HOME}/ant/lib" |
| files="njavac.jar,xproperty.jar"/> |
| </pre> |
| then: |
| <pre> |
| <pathconvert targetos="unix" property="custom_tasks.jars" refid="custom_tasks.jars"> |
| <map from="${env.HOME}" to="/usr/local"/> |
| </pathconvert> |
| </pre> |
| will convert the list of files to the following Unix path: |
| <pre> |
| /usr/local/ant/lib/njavac.jar:/usr/local/ant/lib/xproperty.jar |
| </pre> |
| |
| <h4>Example 3</h4> |
| <pre> |
| <fileset dir="${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. |
