ruby - How do I give one method invoked in a block the ability to see variables set in the context of the calling function? -


I have a module that defines a method, log , which results in a The prefix will add a different method, : : 

  Module M DF log (and block) str = "log in:" block.call say end def ( Value) + value and end   
 I want to be able to use  M  inside a  class  block, such as :  
  Expand square C extension M (say "one" "two"} End   
 and get:  
  # = & gt; "Login: one" # = & gt; "log in: two"   
 Essentially, I should be able to reach values ​​in the  log  in  logs  which only call  logging  Consequently, I like to avoid example variables, global variables, et.  
 What is the correct way to turn it off?   
 
 
 One way to do this is: -  
  Module M def log (and R block) str = "log:" block.call (str) say enddef (str, value) extends str + value end end class c {{s | | Say, "one", "two"} end

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
