To answer my own questions, in case anyone else is interested...
<script language="javascript"><![CDATA[
function helloWorld() {
var echo = project.createTask("echo");
echo.setMessage("Hello World");
echo.perform();
}
]]></script>
<script language="javascript"><![CDATA[
helloWorld();
]]></script>
produces the error
javax.script.ScriptException:
sun.org.mozilla.javascript.internal.EcmaError: ReferenceError:
"helloWorld" is not defined. (<Unknown source>#2) in <Unknown source>
at line number 2
so I conclude that each script task does indeed start with a blank slate.
Moving the function definition into a separate file and trying
<script language="javascript" src="lib/test/test.js"><![CDATA[
helloWorld();
]]></script>
gave the error
build.xml:136: file lib\test\test.js not found.
which is interesting since passing "lib/test/jslint.js" as the first
(<arg value=...) argument to Rhino (in my previous <java> task) worked
okay. However,
<script language="javascript"
src="${basedir}/lib/test/test.js"><![CDATA[
helloWorld();
]]></script>
successfully wrote "Hello World" to the console.
So, my next step is to pull in JSLint's fulljslint.js using the src
attribute, and write a nested "Ant companion" script that allows the
various available options to be set before calling it.
One more question - I see in the Ant manual how to dynamically create
a fileset within the script, and also that the task supports a nested
<classpath> element. Is it possible, though, to have a nested fileset
and access that via the self object?
Andy.
