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
$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
