This can be accomplished through the use of limit: {% for post in site.posts limit:1 %} … Show the post … {% endfor %} You can also use limit and offset together to “feature” your most recent post: <h1>Latest Post</h1> {% for post in site.posts limit:1 %} … Show the first post all big … … Read more
It’s because the definition of the static data member is itself a template. Allowing this is necessary for the same reason you are allowed to have a function template that’s not inline multiple times in a program. You need the template to generate the resulting entity (say, a function, or a static data member). If … Read more
This is talking about a well-established rule for templates – the same rule that allows compilers to diagnose template<class> void f() { return 1; }. [temp.res]/8 with the new change bolded: The program is ill-formed, no diagnostic required, if: no valid specialization can be generated for a template or a substatement of a constexpr if … Read more
All of the previous answers are overkill or outdated. Here’s how you can pass static parameters into templates, directly from HTML+Spacebars code, as of Meteor 0.8.x: <div class=”slot-wrapper”> {{> slot number=”1″}} {{> slot number=”2″}} … </div> <template name=”slot”> <div class=”number”><span>{{number}}</span></div> </template> All you have to do is pass key=”value” parameters in the {{> template}} inclusion … Read more
As is, you’re only reading in a single integer and pushing it into your vector. Since you probably want to store several integers, you need a loop. E.g., replace cin >> input; V.push_back(input); with while (cin >> input) V.push_back(input); What this does is continually pull in ints from cin for as long as there is … Read more
I know this question has already been marked as answered, but I believe what you were looking for is the ‘partial’ syntax. In EJS, you can include the content from one view template in another like so: <html> <head></head> <body> Blah blah blah <%- partial(‘footer’) %> </body> </html>
It depends on how the template is used. For an int, you’re fine. But, if t is an IEEE754 floating point double type with a value set to NaN, neither t < 1 nor t >= 1 are true and so program control reaches the end of the if block! This causes the function to … Read more
Template integral_constant defines a type, keyword constexpr defines a constant. For example std::true_type is std::integral_constant<bool, true>. One of the usage examples is tag-dispatching. template<typename T> void use_impl(const T&, std::false_type) { } template<typename T> void use_impl(const T&, std::true_type) { } template<typename T> void use(const T& v) { use_impl(v, typename std::is_integral<T>::type()); } Live example
First let’s dissect the parameter, T(&)[size]. Read declarations from inside out, right to left, parenthesis group first: It’s an unnamed parameter that is a reference to an array of size size of type T. That is, it accepts a reference to any array, where the type and size of the array are template parameters. If … Read more
Short answer: Whenever referring to a nested name that is a dependent name, i.e. nested inside a template instance with unknown parameter. Long answer: There are three tiers of entities in C++: values, types, and templates. All of those can have names, and the name alone doesn’t tell you which tier of entity it is. … Read more
