Trim() or Truncate() functions in templates

["Lang, Cliff" <cl...@proxicom.com>]

Are there any Trim(), or Truncate() functions accessible from your
templates?  Can you access custom code or java functions directly from a
template?

What I have is an array of users with each user containing a variable
text field being returned with all the rows being displayed in a table.
Like the userlist table used in Flux.

What I want to do is trim the text to say 10 chars, so my table will
format nicely, then I will take the real data and make in available via
an <img alt link>

In a macro it would be something like:

#macro (entryCell $body $width)
  <td bgcolor="$ui.formFieldColor" width="$width">
    <font face="$ui.sansSerifFonts">
      trim($body, $width) <img src="/1x.img" href="#" alt="$body">
&nbsp;
    </font>
  </td>
#end




Any ideas?  Is this more a velocity question?


Thanks,  Cliff

It is possible to do something like this:

	$body.substring(0, 10)

providing that $body is referring to a String. Although it would probably
be better to keep that logic with the code that is building your context.

HTML scripting languages comparable to Velocity

["Gonzalo A. Diethelm" <go...@aditiva.com>]

We are planning the migration of an HTML site from a proprietary
scripting language to something more standard. Because of the
architecture of the system (CGI), Java is not an option right
now. So, having used and enjoyed Turbine and Velocity a lot, I
am looking for a scripting alternative that works pretty much
like Velocity but is not Java-based. Here is what I like about
Velocity:

* simple by design: if, loops, variables.
* works off a "context" where some other process placed a lot
  of <name,value(s)> pairs.
* fast!

I have been trying to find something like Velocity, hopefully as
a stand-alone module (like a mod for Apache). I see a lot of
references to PHP and Perl, but I would really like something
much simpler. Anybody has any suggestions? Thanks,
