Get count of items in a velocity list - liferay

I'm creating a set of custom templates and structures for a Liferay site.
One structure provides for a repeatable section, which its matching template then iterates over.
However, for styling reasons, I need to know how many instances of the repeatable section are actually present, and I need to know before I loop.
So, the template code is something like this:
#foreach($thisChunk in $chunk.getSiblings())
[emit some HTML]
#end
I want to do some conditional logic before the foreach, and emit a different CSS classname on the containing element depending on how many $chunks there are.
Any ideas how to access the number of siblings without looping through them first?

Easy: $chunk.getSiblings().size()
How to find out? It's a plain old Java object (java.util.ArrayList in my quick test). You can find this out when you just temporarily debug your template with $chunk.getSiblings().getClass().getName() and then continue with the interface of that class.

Wayfinder IncludeDocs parameter in Modx is breaking the snippet

I'm quite stuck on an unexpected problem. I'm trying to use Wayfinder to generate a sitemap for a project. The output of the navigation items is as expected, but I need to include a number of documents in addition to the primary navigation elements.
To do this, I have used the includeDocs parameter.
[[Wayfinder? &startId=`0` &includeDocs=`17,18,19,20`]]
When I do this, I get no output at all. Remove includeDocs and I get the standard nav (expected). Use the param and the output is completely empty.
No idea what I'm doing wrong or what (if any) other setting must be defined in order to make this work.
The includeDocs parameter is very misleading. It should rather be named "onlyIncudeDocs" or "restrictTo", since that is what it does. It also requires the docs you include to be directly accessable from your startId, alternatively have the entire path "included".
I would suggest you create weblink resources directly under your startId, and link them to the resources you want to include. That way wayfinder will pick them up by default. (Note that you may need to handle this in your rowTpl for wayfinder, since a weblink stores the actual link in it's content field)
If you also want to include the children of the id's you specify, you would probably be better of slightly revising your resource structure.

Any way in Expression Engine to simulate Wordpress' shortcode functionality?

I'm relatively new to Expression Engine, and as I'm learning it I am seeing some stuff missing that WordPress has had for a while. A big one for me is shortcodes, since I will use these to allow CMS users to place more complex content in place with their other content.
I'm not seeing any real equivalent to this in EE, apart from a forthcoming plugin that's in private beta.
As an initial test I'm attempting to fake shortcodes by using delimited strings (e.g. #foo#) in the content field, then using a regex to pull those out and pass them to a function that can retrieve the content out of EE's database.
This brings me to a second question, which is that in looking at EE's API docs, there doesn't appear to be a simple means of retrieving the channel entries programmatically (thinking of something akin to WP's built-in get_posts function).
So my questions are:
a) Can this be done?
b) If so, is my method of approaching it reasonable? Or is there something stupidly obvious I'm missing in my approach?
To reiterate, my main objective here is to have some means of allowing people managing content to drop a code in place in their content that will be replaced with channel content.
Thanks for any advice or help you can give me.
Here's a simple example of the functionality you're looking for.
1) Start by installing Low Replace.
2) Create two Global Variables called gv_hello and gv_goodbye with the values "Hello" and "Goodbye" respectively.
3) Put this text into the body of an entry:
[say_hello]
Nice to see you.
[say_goodbye]
4) Put this into your template, wrapping the Low Replace tag around your body field.
{exp:low_replace
find="[say_hello]|[say_goodbye]"
replace="{gv_hello}|{gv_goodbye}"
multiple="yes"
}
{body}
{/exp:low_replace}
5) It should output this into your browser:
Hello
Nice to see you.
Goodbye
Obviously, this is a really simple example. You can put full blown HTML into your global variable. For example, we've used that to render a complex, interactive graphic that isn't editable but can be easily dropped into a page by any editor.
Unfortunately, due to parse order issues, EE tags won't work inside Global Variables. If you need EE tags in your short code output, you'll need to use Low Variables addon instead of Global Variables.
Continued from the comment:
Do you have examples of the kind of shortcodes you want to support/include? Because i have doubts if controlling the page-layout from a text-field or wysiwyg-field is the way to go.
If you want editors to be able to adjust layout or show/hide extra parts on the page, giving them access to some extra fields in the channel, is (imo) much more manageable and future-proof. For instance some selectfields, a relationship (or playa) field, or a matrix, to let them choose which parts to include/exclude on a page, or which entry from another channel to pull content from.
As said in the comment: i totally understand if you want to replace some #foo# tags with images or data from another field (see other answers: nsm-transplant, low_replace). But, giving an editor access to shortcodes and picking them out, is like writing a template-engine to generate ee-template code for the ee-template-engine.
Using some custom fields to let editors pick and choose parts to embed is, i think, much more manageable.
That being said, you could make a plugin to parse the shortcodes from a textareas content, and then program a lot, to fetch data from other modules you want to support. For channel entries you could build out of the channel data library by objectiveHTML. https://github.com/objectivehtml/Channel-Data
I hear you, I too miss shortcodes from WP -- though the reason they work so easily there is the ubiquity of the_content(). With the great flexibility of EE comes fewer blanket solutions.
I'd suggest looking at NSM Transplant. It should fit the bill for you.
There is also a plugin called Shortcode, which you can find here at
Devot-ee
A quote from the page:
Shortcode aims to allow for more dynamic use of content by authors and
editors, allowing for injection of reusable bits of content or even
whole pieces of functionality into any field in EE

Dividing long content to subpages

I need to divide long content to sub-pages.
Rule for dividing: Heading1 (H1)
Cms-system: MODX Evolution
As far as i know, there is nothing in modx to use for this kind of problem.
I probably got to do this manually anyway, but i still would like to know if there is a way to do this in MODX Evo / Revo.
Edit:
I need to do this in MODX; sub-pages got to be actual subpages, and original page becomes to container.
Navigation will be done with wayfinder.
Edit2:
All done.. manually. Question still open, though.
This is not possible out of the box and I don't know of any extra that archieves what you want. You would have to write a plugin that acts everytime you save a resource and split up the content, create/delete sibling resources as needed etc. Sounds like a lot of work for what you want to archieve to me.
I suppose you have a look at the MIGX extra. It provides you with a TV with the possibility to store an indefinite amount of distinct TV content sets. Have a look at the documentation and Mark Hamstra's tutorial (with screenshots) to see how it is done. You should define one MIGX entry to consist of a text field for the <h1> and a rich text field for the content of the "subpage".
Afterwards, you can use form customization to hide the original content field and display your MIGX Tv instead.
I think, this is a much easier way to archieve, what you want, and can't think of any way, where you would benefit from actual subpages.
Edit: Sorry, I just recognized that you were asking about Evolution, not Revolution. My solution would work in Revo, but I don't think there's something like MIGX for Evo. Sorry, my mistake.
not 'out of the box' you will have to run your content through a snippet to parse it into separate divs or something that you can run some javascript on to possibly 'tab' the content.
If you need to show the 'subpages' in your navigation, you will probably have to use the gatResources extra to parse your content ~ which will be very expensive on resource usage.
You can (depending on how you're using the tree) just create actual sub resources under the parent resource, using Ditto or Wayfinder to build navigation for it.
If you can't use the tree like that (though from your description I think you can), you could also set up a number of template variables ("content1", "content2", "content3" etc) and show that with a simple snippet or so.

Can I use a Kentico macro to get a partial path?

I would like to know if it is possible to use kentico macros (not necessarily coding a custom one) to access part of the rewritten URL's Path.
Example: http://www.mysite.com/Category/Subcategory/
I would like to get the last part (Subcategory) so that I may then filter content dynamically. The reason I want to use the macro is to simply not have to have 20+ different page templates only so I can have different web part properties.
Assuming you are using Portal templates, and you don't want an 'all items in all subcategories' list on the parent:
Create an Article List web part on the parent page — parent to all the sub-categories.
Set the web part Path to /{0}/{1}/{2}/% (if your path was /Home/Parent/Subcategory for example) or something similar for your environment.
Use the default setting of Inherit for the page template for all subcategory pages.
This will not show anything on the parent page, and the sub-categories will show only the documents under themselves. Note: If you want the subcategory items to have their own views when user digs down to /{0}/{1}/{2}/item, you may need to filter by changing template inheritance, or Document Types on the web part, or something like that if you don't want the whole sub-category list to also show on the item-specific pages.
You can create a custom macro or, you can also use the string operations which are allowed within macros. Please see http://devnet.kentico.com/docs/6_0/devguide/available_macro_methods.htm#string_methods (and you can e.g. use the EndsWith or TrimStrart or something similar).
However, I think the best way would be to create a custom macro which will exactly fit. There might be some combination of macros and macro functions - but I think it is faster just to code a custom one which will cover your need 100%.
Also, you can take a look on the K# if there is something that will fit - http://devnet.kentico.com/docs/6_0/devguide/ksharp_syntax.htm

Can't identify document objects for Context Menus in SharePoint Lists

I'm trying to use JavaScript to find the context menu items being shown and selected from the lists (such as a document library) in SharePoint. I've tracked down a few different function names within core.js, (such as DispEx() and CMOpt()) but I really am having a hard time following the unhelpful variable name mess.
My understanding is that the context menu has to exist within the DOM somewhere - I just can't find out how to retrieve/reference it.
Thanks in advance - this is driving me nuts!
EDIT: I've tried traversing all children from onclick="return DispEx(...)" and I'm not getting anything! This is what I've used to capture that info:
' '
function findStuff(){
var something;
$('[onclick*=DispEx]').children().each(function(){
something = something + this.tagName + '\n';
});
alert(something);
}
It looks like those dom elements might be generated by javascript. Take a look at this article.
Also, you might be able to find the element id's by just searching the dom for text using the contains selector:
$(":contains('context menu item text')").attr('id')
I ended up using an element tracking plug-in to track commonalities between three different installations of SharePoint to get a rough general case. However, I was unable to avoid needed some configuration tailored to the install :(
