Subject RE: Is there an ANT task to replace a <TAG:filename> in the source with the contents of the specified file???
Date Thu, 22 Dec 2005 06:15:08 GMT
Hi,

I've got a fair portion of this working (see below), however does anyone
know how to automate the LOADFILE part below?  

That is, automate finding all files in the "common" directory and
loading the concents of each file into a property for which the property
name is the filename?

....................................................................
<project name="MyProject" default="compile" basedir=".">
    <description>
        simple example build file
    </description>
  <!-- set global properties for this build -->
  <property name="src" location="src"/>
  <property name="build" location="build"/>
  <property name="common" value="common"/>
  
  <target name="init">
    <!-- Create the time stamp -->
    <tstamp/>
    <!-- Create the build directory structure used by compile -->
    <mkdir dir="${build}"/>
  </target>

  <target name="compile" depends="init" description="compile the source " >

	<!-- HOW CAN I AUTOMATE CREATION OF THESE PROPERTIES??? -->
	<loadfile property="snippet1"	srcFile="${src}/${common}/snippet1.lsl"/>
	<loadfile property="snippet2"	srcFile="${src}/${common}/snippet2.lsl"/>

  <copy toDir="${build}">
		<fileset dir="${src}">
			<include name="**/*.*"/>
			<exclude name="${common}/*.*"/>
		</fileset>
		<filterchain>
			<expandproperties/>
		</filterchain>
	  </copy>
  </target>

  <target name="clean"
        description="clean up" >
		<!-- Delete the ${build} and ${dist} directory trees -->
		<delete dir="${build}"/>
  </target>
</project>

....................................................................

The simplest thing would be a <copy> with a nested <filterchain>s and
<filterset>s.
Your TAG would be an Ant property in the snippet.
