add apostrophes with regular expression in perl -


I'm searching the directory with command ls -ld /path1/*.ext1 / path2 / *. Ext2 , e.t.c.

Sometimes, files have special characters in the name: ) , (, etc.).

For this reason, I want to add aproprows in every search directory.

For example: 

  $ filter = "ls -ld / Path1 / * ext1 / path2 / * ext2 "; (1) $ filter = ~ ...; (2)   
 After the regular expression is applied, the result should be:  
  ls -ld '/ path1 / * ext1' '/ path2 / * ext2' (with apostrophes)   
 What is a regular expression (2)  
    
 
 
 $ Filter = ~ s! (\ S +)! '$ 1'! G;   
 Better way to do this:  
  while (globe ("/ path1 / * ext1 / path2 / * ext2") {process_file ($ _);}   
 Regards,

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

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...
