RFC: New #local directive that behaves like #set but puts things into local
context in macro rendering
------------------------------------------------------------------------------------------------------
Key: VELOCITY-680
URL: https://issues.apache.org/jira/browse/VELOCITY-680
Project: Velocity
Issue Type: New Feature
Affects Versions: 1.7
Reporter: Jarkko Viinamäki
Attachments: velocity-local-directive.patch
It would be very useful to be able to set variables that are in local macro
scope. That is, they do not overwrite "global" variables and are thrown away
after macro rendering. This would allow people to build macro libraries that do
not clash so easily with each other.
There is some implementation of a "LocalDirective" in
experimental/localdirective but I didn't quite get it and it doesn't follow the
same syntax as #set. I used a few minutes to hack together this alternative
implementation which behaves exactly like #set but it puts things in local
context only.
There's only one test case since this is Request-for-Comments type of patch.
