I have wondered the same thing. If this were added, I would suggest an
approach similar to XSLT.

 

An XSLT like approach would look something like:

 

            <call target="name">

              <with-parameter name="param1" value="..."/>

              <with-parameter name="param2" value="..."/>

               ...

            </call>

 

and 

            <target name="name">

              <parameter name="param1" default="value"/>

              <parameter name="param2" />

              ...

            </target>           

 

A couple of years ago I started playing with this type of approach.

Subject: [NAnt-users] <call> task with parameters ...

 

Has there ever been any consideration to creating a mechanism for
executing the <call> task with a set of private, local parameters
(properties) which are only available inside the called task?

 

I'm not sure exactly how the syntax would work, but the idea would be to
pass, as an argument to the <call> task, a list of name/value pairs, or
a list of values that are identified by place or order.

 

I find the I often need to fabricate some sort of parameter passing
mechanism, using globally defined <properties> , to control <task>s that
are designed to be general purpose.  Typically, I'll create <property>
elements that have names which include the name of the task:

 

                <property name="mytask_sourceDir" value="sourceValue" />

                <call task="mytask" />

 

I'd much prefer something like:

 

                <call task="mytask" parameters="sourceDir=sourceValue"
/>

 

The assumption would be that the parameter 'sourceDir' is visible only
inside 'mytask'.

 

Thoughts, ideas, considerations?
