MarkupTool
----------
Key: VELTOOLS-97
URL: https://issues.apache.org/jira/browse/VELTOOLS-97
Project: Velocity Tools
Issue Type: New Feature
Components: GenericTools
Affects Versions: 2.x
Reporter: Nathan Bubna
Priority: Minor
Fix For: 2.x
As i grow continually more fond of tools and less fond of macros (though things
are finally starting to look up for macros in 1.6 and the possibility of Raghu
implementing blockmacros), i find myself starting to wish for tools that aid
with markup (mostly html or xml). The idea has occurred to me that i might
find a general MarkupTool for manipulating markup in flexible, repeatable ways.
The API i have in mind might be used something like this:
#set( $foo = $markup.foo.attr('bar', 0) )
$foo
#if( $foo.bar == 0 )
$foo.body($text.danger).attr({'black' : 'white', 'zebras' : $crossing})
#end
which would output
<foo bar="0"/>
<foo bar="0" black="white" zebras="crossing">Danger!</foo>
It's also not hard to imagine ways to allow default attributes/values for
various tags in the configuration for the tool, like
<tool class="org.apache.velocity.tools.generic.MarkupTool"
img="border:0,class:thumb"/>
So that doing just
$markup.img.attr('src',$imglink)
would produce something like
<img border="0" class="thumb" src="http://foo.com/bar.jpg"/>
Granted, i don't have that many situations where this would be useful, but
there have been a few. Also, i wonder if it might serve as a base class for a
JSPTaglibTool (see
