Just use a '!' in-between the $ and the call to the object's
method. That'll
print out nothing if data isn't available (like null). So:
$!weather.getSomeProperty()
But, for something like the weather plugin, the data should
be filled in for
the object by the time you get to the template meaning it
should've already
parsed the XML response.
I wrote the Groovy dispatcher as a proof-of-concept. There
is also a
GroovyPlugin that could parse a Groovy script as a plugin
on-the-fly. Again,
more proof-of-concept. They were fun to write to see how
that type of
scripting could be integrated within blojsom. If you find
'em useful, well
... Rock on.
