indirect property evaluation
Hello all,
I have the following property file that I want to load in my project:
db.system=solid
# ------------------- for Solid ----------------
testfw.solid.system=Solid
testfw.dbvar.system=testfw.${db.system}.system
testfw.db.system=${testfw.dbvar.system}
In my build.xml file, after loading the properties file, I would like
the result of:
<echo message="testfw.db.system = ${testfw.db.system}"/>
To be:
testfw.db.system = Solid
Instead of:
Testfw.db.system = testfw.solid.system
Is it possible to do this "double" evaluation?
Thanks in advance,
-jim-

A simple <scriptdef> can do that.

Nothing in the docs indicates that evaluation happens as long as no futher
replacement is possible, and that nested vars are expanded first. In practise,
things just work as in buildfiles, where "double" eval isn't done either.

This should "just work," in a properties file,
according the the <property> manual page. If not you
should file a bug report.
