Equivalent to webmacro htmlescape

["WATKINS, Andy, FM" <An...@rbos.com>]

Many of the String variables I place within the template
cantain &'s and <'s.

In webMacro I can globally force all returned strings to 
be escaped with the #htmlescape directive.

Can I do this in Velocity? Many template engines have HTML 
escaping enabled by default as this is the most useful.

Will this include most/all of the methods I sent in the
"EncodeXXX context tools" mail within the "Rendering Velocity 
Templates with Texen" thread?

I do have some other usable ContextTools (see "[PROPOSAL] 
generic context tools" in the turbine list. These seem more
fit for the application level that for Vel.

I guess that it would be good to create a Turbine and/or 
Velocity utility library containing such tools (and VMs).
out of which users can pick what they need to avoid re-
inventing the wheel. This library should not be restricted
to Vel, but should contain hints with which templating
engine the classes/files work.

Maybe it would be a good idea to allow #macro's to be passed in a value if
they have a #end. Therefore, it would be easy to do something like this:

context.put("escape", new Escape());

-----------
#macro (htmlescape $pass)
$escape.getText($pass)
#end
-----------

Then in your page:

#htmlescape
<>""
#end

It would make it really easy to emulate #defines that way and seems to be a
cleaner way of implementing things than making everyone create their own
#directives like WM does. :-)

I would be +1 to have it be severely restricted though. For example, you can
only pass in one argument and that argument can only be a String.

There is an Escape.java class that is currently used
in Anakia to do this. You can simply grab that class
place it in the context and go!

context.put("escape", new Escape());

and use it in your template as

$escape.getText($stringToEscape)

We are planning to move all useful tools into a single
location soon and make them available as a useful set
of context tools and the Escape class will be one
of them.
