Yep.

Ah! I've totally missed the note in the wiki (https://wpkg.org/Packages.xml):

 Host
 Host checks were announced in 1.3.0. They appear to allow matching against at least hostname, OS, architecture and environment variables. 

So to remain in my example, i can do:

<variable name="PROXY" value="proxy.%LOCALNET%.%NETNAME%:8080">
	<condition>
		<check type="host" condition="environment" value="PROXY=^$" />
	</condition>
</variable>

In this way i'll set PROXY variable if and only if the same is empty.


Correct? Thanks.
