Ant string functions?
提问by Mike Q
Does Ant have any way of doing string uppercase/lowercase/captialize/uncaptialize string manipulations? I looked at PropertyRegex but I don't believe the last two are possible with that. Is that anything else?
Ant 有没有办法对字符串进行大写/小写/大写/取消大写的字符串操作？我查看了 PropertyRegex，但我不相信最后两个是可能的。那是别的吗？

From this thread, use an Ant <script>task:
从这个线程，使用 Ant<script>任务：
<target name="capitalize">
<property name="foo" value="This is a normal line that doesn't say much"/>
<!-- Using Javascript functions to convert the string -->
<script language="javascript"> <![CDATA[
// getting the value
sentence = project.getProperty("foo");
// convert to uppercase
lowercaseValue = sentence.toLowerCase();
uppercaseValue = sentence.toUpperCase();
// store the result in a new property
project.setProperty("allLowerCase",lowercaseValue);
project.setProperty("allUpperCase",uppercaseValue);
]]> </script>
<!-- Display the values -->
<echo>allLowerCase=${allLowerCase}</echo>
<echo>allUpperCase=${allUpperCase}</echo>
</target>
Output
输出
D:\ant-1.8.0RC1\bin>ant capitalize
Buildfile: D:\ant-1.8.0RC1\bin\build.xml
capitalize:
[echo] allLowerCase=this is a normal line that doesn't say much
[echo] allUpperCase=THIS IS A NORMAL LINE THAT DOESN'T SAY MUCH
BUILD SUCCESSFUL
Updatefor WarrenFaith's comment to separate the script into another target and pass a property from the called targetback to the calling target
更新WarrenFaith 的评论以将脚本分离到另一个目标并将属性从被调用目标传递回调用目标
Use antcallbackfrom the ant-contrib jar
使用来自 ant-contrib jar 的antcallback
<target name="testCallback">
<antcallback target="capitalize" return="allUpperCase">
<param name="param1" value="This is a normal line that doesn't say much"/>
</antcallback>
<echo>a = ${allUpperCase}</echo>
</target>
and capitalisetask uses the passed in param1thus
和capitalise任务使用传入的param1因此
<target name="capitalize">
<property name="foo" value="${param1}"/>
Final output
最终输出
[echo] a = THIS IS A NORMAL LINE THAT DOESN'T SAY MUCH
