Property array?
Hi,
Is there any way to make an array property in Ant? I want to write some
stuff to a file based on an array property. Something like the user enters
this:
<property array name = "colors">
<val = "red">
<val = "green">
<val = "blue">
</property array>
for (i = 0; i < ${colors}; i++) {
<echo file="myfile.txt" append="yes" message="${colors[i]}" />
}
Yeah I'm just making the syntax up as I go along - anything like that?
Thanks

Ok this is what I'm going for -
I wrote a simple java applet framework. The applets need to be signed. So I
made an Ant file which handles signing the applet and combing all support
libraries for the end user. But I'd like a section at the top of my Ant
script where the user can list any additional jars they require, so I can
take that into account of my signing routine for them. So a comma delimited
string would be fine, something like:
// User gives me one string with paths to all jars they need.
<property extra_jars="C:/jarA.jar,C:/testing/jarB.jar,C:/help/jarC.jar">
// I have to tokenize it and sign each one for them:
for (extra_jars) {
sign(nextJar);
}
// I have to create an index.html file for them which houses the applet
// and points to each of those jars.
<filewrite="<applet archive="/>
for (extra_jars) {
<filewrite="${nextJar}"/>
}
// Now I'll copy each one into an export directory.
// ...
Yeah the above is all pseudo-code of course but it gives the idea of what I
want to do. Right now I've just hard-coded the jars being used. Everything
works, it's just that it'd be much nicer to let the user specify one comma
delimited string up top, I parse it and do the rest of the magic for them.
Thanks,
Mark

What is it you are trying to achieve? I have used a comma-separated
string property, split it and iterated over it (using ant-contrib).
Would that work for you rather than writing a custom task?

Hmm I just read through a custom Task tutorial, but I don't think they'll
help, because you can't specify a variable number of attributes, they must
be known in advance. In the examples I've read, your custom Task class has
to have getters and setters for all the attributes you want to use. But if I
want to let my user specify an arbitrary number of attributes, I don't think
that's possible... please correct me if I'm wrong!
Thanks

Hey Mark-
no declaration of property array as far as I can see you can feel free to create your own as in this example
public class MyTask extends Task {
private List conditions = new ArrayList();
public void add(Condition c) {
conditions.add(c);
}
public void execute() {
// iterator over the conditions
}
}
One may define and use this class like this:
<taskdef name="mytask" classname="MyTask" classpath="classes"/>
<typedef name="condition.equals"
classname="org.apache.tools.ant.taskdefs.conditions.Equals"/>
<mytask>
<condition.equals arg1="${debug}" arg2="true"/>
</mytask>
There are a number of hidden implementation details such as which constructors are created and used but the
mechanics of creating the stub are here..more info available at
http://ant.apache.org/manual/develop.html
Maybe some of the committers can weigh in???

You could use Ant 1.8 (unreleased, svn trunk) and
implement your own PropertyHelper delegates to support
something like this.
