Re: Scope of scripts -> workaround

[Alexey N. Solofnenko]

With <scriptdef> you can define the same task differently in different 
targets or you can provide the expression as a parameter into that 
<scriptdef>. <macrodef> with <script> even allows text substitution 
inside the script text  - parameters will be inlined by using @{} notation.

Can you use <scriptdef> instead? See:

i have tried already with no success (probably not hard enough :-),

After fiddling further i have found this workaround:

-----------------
  <target name="pre">
     <script language="javascript">
        var expr = 'function doPrecond() { project.log("HELLO 
PRECOND"); }'
        project.setProperty("expr", expr);
     </script>
  </target>

  <target name="t" depends="pre">
     <script language="javascript">
        eval(""+project.getProperty("expr"));
        doPrecond();
     </script>
  </target>
---------------------

1) Setting a property "expr" to transport the script
2) Executing the script in the calling task "t"
   Note that without the  ""+  at the beginning of eval() it does 
not work

I hope this helps others, like this it is possible to collect
precondition code at a single place.

But still I'm wondering about the scope of scripts ...

Hi,

i have defined a javascript function in a "pre" task,
but when i want to call it later i get:

  ReferenceError: "doPrecond" is not defined

Here is the xml, i call it with 'ant y':

---------------------
  <target name="pre">
     <script language="javascript">function doPrecond() { 
project.log("HELLO PRECOND"); }</script>
  </target>

  <target name="y" depends="pre">
     <script language="javascript">doPrecond();</script>
  </target>
---------------------

Any ideas?

Thanks

Note: This works fine:
   <target name="z">
      <script language="javascript">
         function doPrecond() { project.log("HELLO PRECOND"); }
         doPrecond();
      </script>
   </target>

This fails as well:
   <target name="r">
      <script language="javascript">
         function doPrecond() { project.log("HELLO PRECOND"); }
      </script>
      <script language="javascript">
         doPrecond();
      </script>
   </target>
