Michael J. Kelleher created SLING-2834:
------------------------------------------
Summary: sling:include support two new attributes
Key: SLING-2834
URL: https://issues.apache.org/jira/browse/SLING-2834
Project: Sling
Issue Type: Improvement
Components: Servlets
Affects Versions: Scripting JSP-Taglib 2.1.8
Reporter: Michael J. Kelleher
Priority: Minor
Look at the functionality of c:import for context to this request:
http://docs.oracle.com/cd/E17802_01/products/products/jsp/jstl/1.1/docs/tlddocs/index.html
That tag supports 2 attributes: var and varReader. These two variable prevent
the included resource from automatically being including the output of current
requests 'out' Stream. They do the following:
var - stores the output of the included resource as a String in the scoped
variable identified by 'var'.
varReader - stores a Reader to the included content in the scoped variable
'varReader'.
Both of these would likely need the 'scope' attribute as well.
The current use case I have for this is that I do not want to extend or modify
the functionality of the included resource to serve my new requirement. The
change I need to make to the markup is fairly small, and would not want to have
to maintain a new component for such a small change. I want to include a
transformed version of the included resource. The addition of these two
attributes would allow me to store the resultant markup and transform it before
including it within my current request.
I can certainly write this functionality myself (and will be using
sling:include) but it would be nice if sling:include itself supported this
functionality.
