Re: [Nant-users] Expressions With Variables?

[Gert Driesen]

Troy,
Implicit conversion has not yet been removed from NAnt, we still need to 
come to an agreement on some stuff (this is also what's holding back the 
0.85 release).

Below is a simplified NAnt script and the output it produced.

To my understanding the third message should have printed as "expr2=True" 
similar to how the second message printed.

Merrill,
Implicit conversion has been removed from NAnt, and properties currently 
evaluate as strings... to get around this, you should change your 
expression to:

<echo message="expr2=${50 &lt; convert::to-int(count)}" />
