templating

In shopify I am using liquid templating to get blog posts which are related to products by their tags, like so: <ul> {% for article in blogs.blog.articles %} {% if article.tags contains product.handle %} <li><a href="{{ article.url }}"><p>{{ article.title }}</p></a></li> {% endif %} {% endfor %} </ul> However, if there are no related posts, I would like to display a message such as "No related posts!" My question is how would I do that? I have contemplated trying to get the articles into an array and testing if it is empty, but I am having difficulty finding out how this is done. Thanks! Try

I'm currently using underscore.js for templating in a project, templates are stored in script tags with a type of text/template and loaded by id. I'm wondering if it's possible to continue to use the same system, but move the templates to a separate file? The only way I can think about doing this is declaring the templates as global vars in a separate file, but that seems ugly. Note: I don't want to use Jammit or some other build system for mashing everything together into a single file at deployment time, wondering if there's another solution. I personally use RequireJS to load my templates

I want to do something like this: <script id="tmpl-books" type="text/template"> <ul> <% for (var i = 0; i < books.length; i++) { %> <% var book = books[i]; %> <li> <em><%= book.title %></em> by <%= book.author %> </li> <% } %> </ul> </script> in my code, but I am using JSP so I have to use the {{ }} notation, but when I do this {{ for(var... }} does not work. <script id="tmpl-books" type="text/template"> <ul> {{ for (var i = 0; i < books.length; i++) { }} <% var book = books[i]; %> <li> <em>{{= book.title }}</em> by {{ book.author }} </li> {{ } }} </ul> </script> How can I achieve this? mu is

Is there a way to iterate through keys and values in an object using Hogan.js? I'm unable to find such documented functionality - only iteration over arrays seems to be documented. Is it even possible to iterate through objects in hogan.js (or any other moustache.js implementation)? There is no way to directly iterate over the keys and values in an object in Hogan.js, what sub_stantial is doing is essentialy iterating over an array. Depending on what you want to do you need a bit of prerender code. Supposing you have an object o that is { k1: "v1", k2: "v2" } . And you want your rendered

I would like to add a simple template language to my application based on Seam / JSF to let the users compose their own email. Since I don't want to create a new parser, I would like to use the Unified Expression Language setting the context all by myself. How can I do that? If you're sitting inside the JSF context, then just use Application#evaluateExpressionGet() to programmatically evaluate a string containing EL expressions. String unevaluatedString = convertMailTemplateToStringSomehow(); FacesContext context = FacesContext.getCurrentInstance(); String evaluatedString = context

I'm using Smarty for the first time. It works fine on my laptop (MAMP) but when I try and run a basic template on my production server (Windows) I get this error message: Fatal error: Uncaught exception 'SmartyException' with message 'unable to write file C:\Inetpub\vhosts\path\to\web\root\smarty\templates_c\wrt516e53290e2095.47946913' in C:\Inetpub\vhosts\path\to\web\root\smarty\libs\sysplugins\smarty_internal_write_file.php:44 Stack trace: #0 C:\Inetpub\vhosts\path\to\web\root\smarty\libs\sysplugins\smarty_internal_template.php(201): Smarty_Internal_Write_File::writeFile('C:\Inetpub\vhos...'

I want to add a class of 'active' to the nav list item that is currently being rendered by Iron Router. Here's my markup: <ul> <li> {{#linkTo route="option1"}} <span class="fa fa-fw fa-option"></span> Option 1 {{/linkTo}} </li><li> {{#linkTo route="option2"}} <span class="fa fa-fw fa-option"></span> Option 2 {{/linkTo}} </li> </ul> I've read through the guide and various articles but can't find this covered anywhere. Assuming I'll need some sort of helper? I think you might find meteor-iron-router-active useful, as it has helpers for the following: isActiveRoute isActivePath Here's how I do it
