editor - vim formatting command -

Today I unknowingly typed something when the cursor was on a very long line and it forms my line, to limit it Braking length of several lines of This line looks like this: 

  Fu ("It is a very long line ('% s' is left 'right') and it will never end." PNode-> left C_str (), pNode- & gt; right.c_str ());  
  Foo ("This is a very long line (left '% s' is correct) and it will never" end ", pNode- & gt; left.c_str ( ), PNode- & gt; right.c_str ());  
 
 What did I press?

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas?

I have a title-setter on the window view, which wraps the actual Gui title.

Ask yourself how you will test it? If you do a window presentation. View. Tight = "Title", how can you test that the presenter is setting the title?
