Ok, here's a 'real-world' example of how the comments at the end of the
line looks and works, from the header of www.peoplesarchive.com :
original code:
<ul class="navigation">
<li class="first
#if ($sectionName.equals("home"))
selected_list_item
#end
"><a href="/">home</a></li>
<li
#if ($sectionName.equals("browse"))
class="selected_list_item"
#end
><a href="/browse/">browse</a></li>
<li
#if ($sectionName.equals("search"))
class="selected_list_item"
#end
><a href="/search/">search</a></li>
<li
#if ($sectionName.equals("playlists"))
class="selected_list_item"
#end
><a href="/playlists/">playlists</a></li>
#if ($subscription == 0)
<li
#if ($sectionName.equals("login"))
class="selected_list_item"
#end
><a href="/login/">login</a></li>
<li
#if ($sectionName.equals("register"))
class="selected_list_item"
#end
><a href="/register/">register</a></li>
#else
<li
#if ($sectionName.equals("logout"))
class="selected_list_item"
#end
><a href="/login/logout.jsp">logout</a></li>
<li
#if ($sectionName.equals("myarchive"))
class="selected_list_item"
#end
><a href="/myarchive/">my archive</a></li>
#end
<li
#if ($sectionName.equals("about"))
class="selected_list_item"
#end
><a href="/about/">about us</a></li>
<li
#if ($sectionName.equals("contact"))
class="selected_list_item"
#end
><a href="/contact/">contact</a></li>
<li
#if ($sectionName.equals("feedback"))
class="selected_list_item"
#end
><a href="/feedback/">feedback</a></li>
</ul>

The first version makes the header twice as long as all the whitespace
pads it out, the second is normal but the code is now awful!

+1 for gobbling structured templates.
We use velocity for most of the "backstage" area at Pandora. It's
made development so much easier! However, the final HTML looks quite
messy due to all of the extra whitespace introduced by the velocity
templates.

I would be very interested in a solution to this problem. From a code
layout point of view this would be an important feature. Consider:
<div>
"
#if ($somevar)
$somevar
#else
nothing here
#end
"
</div>
This nicely formatted code makes it easy to see what's going on but
will
make the html render with spaces in it like so (if $somevar is false or
null):
' nothing here '
Now this is a silly example and in this case it would be much easier to
simply do this to eliminate the problem:
<div>
#if ($somevar)
"$somevar"
#else
"nothing here"
#end
</div>
but in more complex examples you'd either have a great amount of
duplicated HTML, which makes it bad to maintain and update, or you'd
have to make unreadable code (everything on one line with no white
spaces).
I converted an old nasty taglibbed jsp into velocity and although I
cleaned up the html (removing 20+ unnecessary nested tables) the
filesize of the velocity version was actually slightly bigger than the
old version because of all the whitespace.
So... I would very much like velocity to perhaps remove whitespace
between a directive (i.e. a # statement) and any other code.

List,
We noticed in #parse'ing an .vm file, excess whitespace, or linefeeds,
are appearing in our templates after merge.
For example, where a '+' indicates a line feed or carriage return:
[mystyles.vm]
+
#set( $foo = "Copyright (c)")
+
#set( $bar = "2006" )
+
[myemail.txt]
#parse("mystyles.vm")

Can these extra lines be managed in some way?
