Question

Ant有没有办法做字符串大写/小写/ captialize / uncaptialize字符串操作？我查看了PropertyRegex，但我不相信最后两个是可能的。还有别的吗？

Answer 1

From this thread，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>

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

更新以获取WarrenFaith的评论，将脚本分成另一个目标，并将属性从调用目标 传递回调用目标

使用ant-contrib jar中的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>

和capitalise任务使用传入的param1因此

 <target name="capitalize">

        <property name="foo" value="${param1}"/>

最终输出

   [echo] a = THIS IS A NORMAL LINE THAT DOESN'T SAY MUCH

您可以使用script任务并使用jsr223支持的脚本语言（如javascript，jruby，jython，...）进行字符串处理

Ant字符串函数？
