Brian,
There isn't any built-in way to evaluate the properties that I could see.
I wrote the following script, a while back, to do what you're reqesting.
Call it as follows:
<property name="x" value="${dbs::expandValue(y,5)}" />
Where y is a property with unevaluated properties
5 is the number of times to recurse and re-evaluate the expression
Or your example:
<property name="_message" value="${dbs::expandValue(message,1)}"
dynamic="false" />
I hope this helps,
Noel
<script language="C#" prefix="dbs" mainclass="dbsHelper" >
<code>
<![CDATA[
[Function("expandValue")]
public static string expandValue(string value, int depth)
{
return dbsHelper.expandValue(value, depth);
}
class dbsHelper
{
static Project _project;
public static void ScriptMain(Project project)
{
_project = project;
}
public static string expandValue(string value, int
depth)
{
if (value.IndexOf('$') < 0 || depth == 0)
return value;
value = _project.ExpandProperties(value,
Location.UnknownLocation);
if (depth > 0)
value = expandValue(value, depth-1);
return value;
}
}
]]>
</code>
</script>

Subject: [NAnt-users] Want to force expansion of properties in a string
I have a nant script that generates messages. I want to pass in the
message place holders for the properties from the command-line along
with the properties values. For instance:
nant -buildfile:test.build -D:message="mything's value=${mything}"
-D:mything=12345
given the following project:
<project name="test.build" xmlns="http://nant.sf.net/schemas/nant.xsd";>
<target name="test" >
<property name="mything" value="" />
<property name="_message" value="${message}" dynamic="false" />
<echo message="${_message}" />
</target>
</project>
should produce the resulting string "mything's value=12345" from my
echo statement.
Instead I am getting "mything's value=${mything}". Is there a way to
force the property in the string to be expanded?
