Hi,
I have a situation where I have a path with a number of path segments,
and, for each path segment, I need to transform that path segment
(presumably using a mapper), and then pass the original path segment AND
the transformed path segment to a macro.
The problem is that it's not clear to me how to transform the path,
without assigning the transformed path to an immutable property.
The slightly simplified build file is below.
|<?xml version="1.0" encoding="ISO-8859-1"?>
<project name="scxml-js" basedir="." default="generate-javascript">
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="${basedir}/lib/build-java/ant-contrib-0.6.jar" />
</classpath>
</taskdef>
<property name="backends" value="switch,table,state"/>
<property name="browsers" value="firefox,ie,chrome"/>
<property name="for-ie" value="is-for-ie,is-not-for-ie"/>
<path id="scxml-tests-xml">
<pathelement location="test/kitchen_sink/KitchenSink.xml"/>
<pathelement location="test/kitchen_sink/KitchenSink_dataModule.xml"/>
<!-- ... -->
</path>
<!-- the macro call java with specific arguments -->
<macrodef name="compile-with-scxml-js">
<attribute name="backend"/>
<attribute name="test-path"/>
<attribute name="out-path"/>
<sequential>
<java classname="org.mozilla.javascript.tools.shell.Main"
output="@{out-path}">
<classpath>
<pathelement location="lib/java/js.jar"/>
<!-- ... -->
</classpath>
<arg value="${basedir}/runner.js"/>
<arg value="${basedir}"/>
<arg value="src/javascript/scxml/cgf/main"/>
<arg value="--backe...@{backend}"/>
<arg value="--beautify"/>
<arg value="--ie"/>
<arg value="@{test-path}"/>
</java>
</sequential>
</macrodef>
<!-- run unit and performance tests -->
<target name="generate-javascript">
<for list="${for-ie}" param="for-ie">
<sequential>
<for list="${backends}" param="backend">
<sequential>
<for param="test-path">
<path refid="scxml-tests-xml"/>
<sequential>
<!-- do some manipulation -->
<pathconvert property="target-test-path">
<path path="@{test-path}"/>
<chainedmapper>
<flattenmapper/>
<globmapper from="*.xml"
to="build/@{backend}/@{for-ie}/*.js"/>
</chainedmapper>
</pathconvert>
<dirname property="target-test-path-dir"
file="${target-test-path}"/>
<echo>${target-test-path}, ${target-test-path-dir}</echo>
<!-- execute some tasks, call a macro -->
<mkdir dir="${target-test-path-dir}"/>
<compile-with-scxml-js-ie
test-path="@{test-path}"
backend="@{backend}"
out-path="${target-test-path}"/>
</sequential>
</for>
</sequential>
</for>
</sequential>
</for>
</target>
</project>

Because target-test-path and target-test-path-dir will only be assigned
to once, this will repeatedly echo the following:
[echo] build/switch/is-for-ie/KitchenSink.js,
/home/jacob/workspace/gsoc2010/git-scxml-js/scxml-js/build/switch/is-for-ie
I'd appreciate any guidance anyone can offer. Thanks,
Jake
