Foreach syntax and whitespace

[Dave Dutcher <dj...@earthlink.net>]

Hello,

I'm using Velocity to generate some html, and I have a script like this:

#foreach($email in$email_list)
<p>$email</p>
#end

And it works great, but I am trying to enter the VTL directly into a WYSIWYG
html editor.  Maybe I will have to edit the html file once the editor is
done with it, but I'd like to avoid that so I don't have to re-edit the html
file everytime I change something with the editor.  Sometimes though the
editor will end up splitting the foreach line like this:

#foreach($email
in$email_list)
<p>$email</p>
#end

Then when I try to merge the html file with a VelocityContext I get an
exception.

I tried doing this:
#foreach($(email)in$email_list)

but that didn't work either.  It seems that Velocity needs a space, (not a
CR/LF) between $email and in and nothing else will work.  Is that true, or
is there something I'm missing?

Thanks,

Dave

Hi Dave,

A tip that I've found works with my editor (Dreamweaver) is to insert VTL 
within a HTML comment whenever I can.  Often the so called comment is preserved 
with no changes to spaces or returns.


<!--  #foreach($email in $email_list)  -->
 <p>$email</p>
<!--  #end  -->

Of course, this outputs as the following, which displays fine in the browser.

<!--    -->
 <p>email1</p>
 <p>email2</p>
 <p>email3</p> (etc)
<!--   -->
