Hi devs,
Some methods must be captured so that they don't create output when
called from velocity, usually with something like:
#set ($var = $obj.doSomething())
Where $var is a variable whose content isn't needed and won't be
used. And everyone seems to have his favorite name for it: $discard, $ok, $ignore...
I'd like to have a single variable name, so that in the end we don't
end up creating 5 different variables for the same goal. So, which one do you prefer:
1. $discard 2. $discarded 3. $ignore 4. $ignored 5. $ok 6. $output
We can also think of:
7. $dummy (I always use this one) 8. $unused
How about:
9. $void
+1, that's what I'm using usually too
I would add that "void" make clean it's nothing while "discard" could be a real (probably boolean) variable IMO
$void does sound good if you think of java methods with void return type. Or, more generally, a procedure rather than a function, which is actually our use case for velocity. Even if "void" can be used as a verb or even a boolean variable name (i.e. a product's warranty status or whether to change it), it's less common than "discard". I would be +0.5 for $void. Thanks, Eduard
But I don't have a strong opion about this.
$ok is the shortest, thus easier to type, faster to parse, and
lighter on the total size of the wiki.
The size is definitely a bad argument. Let's remove all comments
it'll slim down the wiki size… yeah! :)
Faster to type is also not a good argument. Using meaningful variable
names is better.
On the other hand, I prefer $discard since it's more meaningful, it
conveys exactly what that line does: "$discard the output of this method call".
They're all fine with me except $output.
Thanks -Vincent
