Is it possible to nest helpers inside the options hash with handlebars?
Update: Handlebars now supports subexpressions, so you can just do: {{view “SearchView” (t ‘search.root’)}}

Difference between instantiation and specialization in c++ templates
(Implicit) Instantiation This is what you refer to as instantiation (as mentioned in the Question) Explicit Instantiation This is when you tell the compiler to instantiate the template with given types, like this: template Struct<char>; // used to control the PLACE where the template is inst-ed (Explicit) Specialization This is what you refer to as … Read more
How to define a template member function of a template class [duplicate]
template<typename T> template<typename T2> void Foo<T>::Bar(const T2* t) { // stop tearing your hair out }
Template partial specialization for integral non-type parameters and non-integral non-types, difference between g++ and clang
I will dedicate my answer to case #4, because according to the OP’s EDIT, the compilers now agree on cases #6-8: # | The code | g++ (6.1) | clang++ (3.8.0) | 4 | foo<double&, d, d> | #1 — why? | #2 as expected | Seems like clang++ 3.8.0 behaves correctly and gcc 6.1 … Read more
Restrict variadic template arguments
Yes it is possible. First of all you need to decide if you want to accept only the type, or if you want to accept a implicitly convertible type. I use std::is_convertible in the examples because it better mimics the behavior of non-templated parameters, e.g. a long long parameter will accept an int argument. If … Read more
Instantiation of template member function
You can use the following syntax in Class.cpp: template void Class::function(int); The template argument can be omitted because of type deduction, which works for function templates. Thus, the above is equivalent to the following, just more concise: template void Class::function<int>(int); Notice, that it is not necessary to specify the names of the function parameters – … Read more
What is the correct way to represent template classes with UML?
Normal rectangle with a dotted rectangle in the top right corner, to represent the template parameter. Something like this: ……. ___________: T : | :…..: | | | ClassName | | | |______________|
Razor views as email templates
You can use http://razorengine.codeplex.com/ to achieve this. It allows you to use razor outside of mvc. string Email = “Hello @Model.Name! Welcome to Razor!”; string EmailBody = Razor.Parse(Email, new { Name = “World” }); It’s simple to implement and it’s available on http://nuget.codeplex.com/ for easy integration into your projects.
Undefined reference error for template method [duplicate]
Templated code implementation should never be in a .cpp file: your compiler has to see them at the same time as it sees the code that calls them (unless you use explicit instantiation to generate the templated object code, but even then .cpp is the wrong file type to use). What you need to do … Read more
How can I declare a member vector of the same class?
This paper was adopted into C++17 which allows incomplete types to be used in certain STL containers. Prior to that, it was Undefined Behavior. To quote from the paper: Based on the discussion on the Issaquah meeting, we achieved the consensus to proceed* with the approach – “Containers of Incomplete Types”, but limit the scope … Read more
