T5: 5.0.8 whitespace
So this ticket has been implemented in svn:
https://issues.apache.org/jira/browse/TAPESTRY-2028
And now I need whitespace... so how can I get it back? Is there or isn't
there a way to disable this? Im using loop to output links (pagelinks),
and i have whitespace behind in the body so there is separation.
Unfortunately, it's getting stripped. Is there a workaround?
On a related note, is there a way to know if im on the last iteration of
the loop, so i could for example, follow all but the last with a ","?
This may be outside the scope of loop as currently implemented, but i
can see it being useful.

I think that isEven or isOdd probably has enough common usage to be
worth exposing to child components too.

Insert css class attributes for first/last. :)
Incidentally, regarding my earlier suggestion of making your own
component, you're absolutely right that loop would be difficult to
duplicate. But you don't need to duplicate it, per se. Just composite
it. Make your own component with the same parameters as loop, plus
your "delimiter" parameter. Then define a loop component, and just
use the "inherit" binding prefix for all of the parameters.
Then you can throw together a template with your loop, the if
component, the delimiter, and a <t:body/>, and you're set. In fact, I
just did this... took less than ten minutes to do. I suppose since I
already wrote it, I could package it up and throw it onto tassel or
something, if you want.

Re: T5: 5.0.8 whitespace
Posted by Josh Canfield <jo...@thedailytube.com>.
Hmm... output optional content or an entirely different rendering for the
first object or last object? In my case (www.thedailytube.com) the first
object rendered is highlighted with a bigger image and more text of the
description displayed. In an email application your thread page you might
only want to show the full contents of the last entry and minimized entries
for the rest.
Currently I'm just testing _index == 0 from within my component, but it'd be
handy if I didn't have to define the _index and could just call
_loop.getIsFirst() when picking CSS, or <t:if test="loop.isFirst"> when
selecting the components to render.
I think that creating a simple delimited string is something that should be
easy to do, but I don't think it makes sense to tack it on to the loop
component. It'd be better to make it trivial to write your own component, or
use the features of the component to get that effect.

Out of curiosity and within the scope of markup rendering in a looping
context, what would one do with with isFirst/isLast knowledge, apart
from using it to insert a delimiter?

Adding delimiter to the loop component sounds like a poor design
choice to me. It seems like the right thing to do would be to make
isFirst/isLast type attributes available from the loop.

Thanks for the reminder. As a note to others interested in this thread,
I created a JIRA suggesting the addition of a delimiter parameter in the
Loop.

I have been keeping the nightly documentation up to date with these changes.

The main site will only be updated when a new release is generated,

Perhaps idealistic CSS, but not realistic - at least for my browser
support matrix. If I'm not mistaken not even IE 6 supports these pseudo
selectors, and I can't see how one can hope to fare well without
supporting it. Of course I see this as annoying and unfortunate, as I
agree with you in theory.

I'm not sure this would gain him much. He'd still need to know how to
figure out if the list item is the last one in the iteration. Of course, it
would address his whitespace problem.
I think what Chris wants is something that I've been advocating for for a
little while now. That's something quite similar to the for "component" of
Django:
http://www.djangoproject.com/documentation/templates/#for
With the introduction of the "var" prefix, the above could be approximated
by the addition of two new component parameters: {first, last}. Each could
be bound to a boolean and with the "var" prefix that could be accomplished
without any additional Java code. The value could then be used in an If
component in order to perform the proper rendering.

Chris,
This is a job for CSS.
You are creating a list, so render your links in an unordered list, and set
the class attribute for the last item to "last" and then use a CSS recipe
for creating inline lists:
ul,li {
display:inline;
margin: 0;
padding 0;
}
li:after {
content: ", ";
}
li.last:after {
content: ".";
}
You may need to set any surrounding paragraphs to display inline as well if
you want the list included in the text flow.

The var: binding prefix is much more limited than prop:, and prop: is
more limited than T4's use of OGNL. But it's all part of the grand
plan :-)
Building a more complex expression language is something that will
wait for a later release, as you can write code in your component to
perform these types of operations (and still get instant reloading).

Re: T5: 5.0.8 whitespace

This almost works. Using the way you suggested as is oddly emits a comma
only after the last element. Unfortunately I can't, at least not that I
know of, express a "less than" clause like so:
<t:if test="var:index < ${post.tags.size()}">,</t:if>
T5 doesnt allow '<' here. As far as creating my own goes, I'm wondering
if you've looked at the source of the core Loop component. If not, take
my word for it, it's scary. If I could just subclass it and override a
render method to honor a new parameter, it would probably be easy. Alas
the T5 black magic prohibits this. At this point I see 2 options:
1) Do as you suggested and create my own loop, which will take a good
bit of focused time to first understand why the internal loop does
things the way it does.
2) Create a component that loops through a list and outputs a delimited
list of pagelinks. The nasty part of this is that's its done in rigid
java code - but it works.
Has no one else done this yet?

What you /might/ be able to do (to avoid the java code), is to use var
here... I haven't played with the var prefix yet, so this is a "try
and see" idea. :) But. Something like:
<t:loop source="strings" value="var:string" index="var:index">
<t:if test="var:index">,</t:if>
<a href="#" t:type="pagelink" page="nada" context="var:string">$
{var:string}</a>
</t:loop>
If that works, you could even write your own DelimittedLoop component
and not have to duplicate the logic elsewhere.

Sure, but I don't think it addresses my problem. My problem isn't
creating a list, my problem is delimiting values on each iteration of
Loop, without having a trailing or leading delimiter.

Hi Chris,
may i advise you the listbinding from t5components ?
<ul>
<li t:type="Loop" source="list:\"value 1\", \"value 2\", \"value
3\"" value="element">
${element}
</li>
</ul>

That would work of course, but I'd like to do something like this:
<t:loop source="strings" value="var:string" index="prop:index"
delimit=", ">
<a href="#" t:type="pagelink" page="nada"
context="var:string">${var:string}</a>
</t:loop>
And then each element would be separated by my delimiter without any
extra java code.

How about testing the value of index?
Something like:
.java:
private int index;
public int getIndex() { return index; }
public void setIndex(int i) index = i; }
public boolean isFirst() { return index==0; }
.tml:
<t:loop source="strings" value="var:string" index="prop:index">
<t:if test="prop:first" negate="true">
,
</t:if>
<a href="#" t:type="pagelink" page="nada" context="var:string">$
{var:string}</a>
</t:loop>

Sorry, I missed the "check if first" part. How can you do such a check
in Loop? The "If" can test, but what can you test in a Loop? nothing
that I know of will tell you where in the iteration you are.

Re: T5: 5.0.8 whitespace

That will just 'reverse' the problem (a leading comma instead of a
trailing one). Suppose I have a list of strings like:
{ "one", "two", "three" }
And a Loop to display:
<t:loop source="strings" value="var:string">
<a href="#" t:type="pagelink" page="nada"
context="${var:string}">${var:string}</a>,
</t:loop>
This renders: one,two,three
If do as you suggest:
<a href="#" t:type="pagelink" page="nada"
context="${var:string}">${var:string}</a>,
This would render: ,one,two,three

just reverse where you write the ","
instead of checking if last and putting comma behind
check if first and put comma in front
