Question

When debugging it’s quite common for me to use things such as Zend_Debug and die() in the PHP to locate an issue. Occasionally I forget to take these out before committing my code. So I was wondering…

How do I write an ant build.xml target which checks all the files in my application for specific strings and fails if they have been found?

Basically, I’m after a reverse grep command which fails when it finds a string.

Any ideas?

Also, given my build.xml file looks like this (I’ve removed most of my targets to make it short), how do I make it work?
I don’t know how ant works, so I’m after a ‘drop-in’ solution or good instructions.

<?xml version="1.0" encoding="UTF-8"?>
<project name="API" default="build" basedir=".">
    <property name="source"  value="application"/>

    <target name="build" depends="prepare,lint,phpcpd,phpdox,phpunit,phpcb"/>

    <target name="clean" description="Cleanup build artifacts">
        <delete dir="${basedir}/build/api"/>
    </target>

    <target name="lint">
        <apply executable="php" failonerror="true">
            <arg value="-l" />
            <fileset dir="${basedir}/${source}">
                <include name="**/*.php" />
            </fileset>
            <fileset dir="${basedir}/tests">
                <include name="**/*.php" />
            </fileset>
        </apply>
    </target>
</project>

Within the lint target (after the apply element) add

<fileset id="die-files" dir="${basedir}/${source}">
    <include name="**/*.php" />
    <contains text="die()"/>
</fileset>
<fail message="The following files contain "die()": ${ant.refid:die-files}">
    <condition>
        <resourcecount when="greater" count="0" refid="die-files"/>
    </condition>
</fail>
