Example, this code:
class A {|}
class B
{
   |
}

struct A {|}
struct B
{
    |
}


After apply this patch, it's auto changed to:
class A {|};
class B
{
   |
};

struct A {|};
struct B
{
    |
};


A semicolon add here: };

What will happen if I type:

{|}
or
{
    |
}

Sorry, I do not know what you mean.
If not class or struct, then it do nothing.

Update: support 'enum' keyword
Update2: support 'union' keyword  :P

A small suggestion for your patch: you should also support the "union" keyword.

Wow, that was fast! You guys are great! :)

What happens in my whole file looks like:
{ | }
???
You don't check for the first line / character in the editor being reached, or am I wrong?!
If so, your code my result in an infinite loop, maybe even in a crash.

@morten:

Loaden use this for condition below:
while (text.IsEmpty() && --keyLine);

Look at the variable: keyLine, when it reaches zero, the loop will break, so, there will never be a infinite loop.

Indeed. I missed that. C++ style calculations inside an if/while statement - I don't allow such in my coding style, so I am not used to it.

Please test this demo:


class A



{

If not use "do/while", when type '{', it can not judge the class type. :(

??? Strange. I did not apply in my copy yet, but what if you use:
               do
               {
                   int keyPos = control->GetLineIndentPosition(keyLine);
                   int start = control->WordStartPosition(keyPos, true);
                   int end = control->WordEndPosition(keyPos, true);
                   text = control->GetTextRange(start, end)
                    text.Trim();
                   --keyLine;
               }
               while ( text.IsEmpty() && (keyLine>0) );

Notice: This is untested.

But noone will write this kind of code, search to the previous line is enough.

I test it, but it's not work for 'namespace {' question.
I will check it, and fix this problem.

      public B3,

Replace A, B1-4 with very long strings and for sure someone will write such code :)


namespace my
{
}; <--- here the semicolon is not needed!

Sorry, I can not reproduce this problem.
Can you give me some demo?

I make a new patch, welcome test.

That's what I wanted to point out:)
Although most compilers in non-strict mode will silently convert that trailing semicolon to ((void)0); and ignore it, nevertheless it doesn't belong there.
