[FreeMarker-user] Multiple layout section override ?

Discussion:

Albert Kam

2013-03-06 13:46:26 UTC

I am aware that i can use macros for layouting, for example, a main layout
that contains header, left body section, center body section, footer.

Based on the examples i have googled, like this one here
http://wendefer.blogspot.com/2007/09/handy-tip-for-layouts-in-freemarker.html,
i can use <#nested> in the main layout for dynamic values for other
templates that use this main layout macro.

But in my case, i would like the other templates to be able to 'override'
more than 1 <#nested>, for example, providing the content of left body
section -and- center body section (like apache tiles).

Is this supported, or maybe is there any other approaches to do this ?

Sadly, there's still no built-in solution for this. I have seen two
approaches to work this around. First is passing macros to the layout
macro:

<#macro myHeading>
...
</#macro>

<#macro myFooter>
...
</#macro>

<@myApp.page heading=myHeading body=myFooter>
... this is the body ...
</@myApp.page>

It's kind of noisy though. So I would rather implement this (some
deeper FreeMarker knowledge is needed):

<@myApp.page>
<@block name="heading">
...
</@block>
<@block name="body">
...
</@block>
<@block name="footer">
...
</@block>
</@myApp.page>

Here @block has to be implemented by you, in Java
(TemplateDirectiveModel). The layout macro need to push a
TemplateHashModel into a stack that's stored in a custom Environment
attribute, then call #nested. Then, @block should capture the content
generated inside its body, get the topmost TemplateHashModel from said
stack, and put the captured content into with block name (like
"heading") as the key.

Thanks for the ideas.

I have tried the macro solution from your reply, seems great !

the layout file :
<#macro defaultHeader>
defaultHeader here
</#macro>

<#macro defaultFooter>
defaultFooter here
</#macro>

<#macro layout header=defaultHeader footer=defaultFooter>
<@header />
<#nested>
<@footer />
</#macro>

the 'page' file that overrides a header n provide a body as usual:
<#macro overrideHeader>
header overriden
</#macro>

<@layout header=overrideHeader>
body overriden
</@layout>

The output is :
header overriden
body overriden
defaultFooter here

------------------

I have not tried the java directive yet. I would like to clarify some

The layout macro need to push a TemplateHashModel into a stack that's

stored in a custom Environment attribute,
How to do this inside the macro, is it by using #assign directive to store
to the global variable so it can be fetched later from the
TemplateDirectiveModel's Environment via the getGlobalVariable() ?
If yes, how do i assign a 'hash' to a global variable ? And i dont see any
stack in the Environment api doc.

then call #nested.

This is as simple as providing <#nested> in the macro, correct ?
the topmost TemplateHashModel from said
stack, and put the captured content into with block name (like"heading") as
the key.
So, this means that the <#nested> in the layout doesnt produce any output
at all.
And to produce the header, body, footer, i have to loop all the captured
contents stored in the global variable, correct ?
And if this is so, what is the convenient way to provide a default content
for a section that might not be overriden ?

Thank you so much !

You can't, or at least, shouldn't implement the more technical parts
of this in FTL. FTL, being an MVC View language, really just meant to
get everything ready from the data-model or from a directive/method
that was implemented in Java. So certainly you need to write a few
directives like:

- <@my.setBlock name="whatever">output will be captured here</@my.push>
which stores the captured output into the top hash of said stack.

- my.blocks.whatever: get an earlier set block from the top hash of
the stack.

- For convenience, maybe: <@my.printBlock name="whatever" />
which is basically <#noesacpe>${my.blocks.whatever}</#noescape>.

- <@my.collectBlocks>...</@>
which pushes a new empty hash into said stack, then pops it at the
end

Then can use these when writing macros and just forgat about the
technical parts.

As of the technical parts... freemarker.core.Environment has a
set/getCustomAttribute method. There's no restriction regarding the
type of the attribute value, so there *you* can implement that stacks.

As of the hash thing... My quick idea was that the stack items are
themselves TemplateHashModelEx instances, so that you can easily
access them from the templates, but this really and unimportant
detail, and above I haven't even used it in that form. Because above
my.blocks is a TemplateHashModelEx that shows the topmost stack item.

Anyway, this should really be a core feature of FreeMarker, but I
don't think I will have time to implement this in the near future,
so...

Well, I would put them into that stack that's stored in an Envionment
attribute, but that's similar to a global variable in its scope and
life-cycle.

For example, <@my.printBlock name="whatever" /> could have optionally

Thanks for clearing it up Daniel.
I am currently applying the macro solution for the time being as it works
and i have more things to do for now.
I will be posting to this thread again if i manage to find the time to impl
the custom block directive.

Sorry about that previous post! I accidentally sent the email, I just love
coding in a bad browser based email client!

What I have done in the past is this:

<#-- DEFINE THE MACRO -->
<#macro layout>
<html>
<body>
<div id="head"><#nested "head" /></div>
<div id="content"><#nested "content" /></div>
</body>
</html>
</#macro>

<#-- NOW, CALL THE MACRO -->
<@layout ; section>
<#if section = "head">
Write your header section here.
<#elseif section = "content" >
Write your content section here.
<#else>
Unsupported section??

Thanks for the guide Tony !

Actually i have thought of using the loop variable param,
but i wonder how to provide the default section content,
since what i intended is to override some sections as needed, and use the
default sections if not 'overriden'

Example :
for page1.ftl, i want to supply the body only, but use the default
left-panel, default header n default footer
for page2.ftl, i want to supply both the body and left-panel, and still use
the default header n default footer

What I have done is this:

<#macro layout>
<html>
<body>
</body>

</#macro>

can use macros for layouting, for example, a main layout that contains
header, left body section, center body section, footer.
Based on the examples i have googled, like this one here
http://wendefer.blogspot.com/2007/09/handy-tip-for-layouts-in-freemarker.html
[1], i can use in the main layout for dynamic values for other templates
that use this main layout macro.
But in my case, i would like the other templates to be able to 'override'
more than 1 , for example, providing the content of left body section -and-
center body section (like apache tiles).
Is this supported, or maybe is there any other approaches to do this ?
