Hi all,

I have a group of C++ source files where I have the following text on a
single Lines:

class MyReallyLongClassNameThatIsTooLongToFitInEightyCharacters : public
SomeClassTemplate<InstantiatedDataType>

What I want to do is to split this line at the ":" so that everything
after the colon appears on the next line (indented 4 characters) like so:

class MyReallyLongClassNameThatIsTooLongToFitInEightyCharacters
    : public SomeClassTemplate<InstantiatedDataType>

I have written the following code:

while(<>)
{
    $code_line = $_;
    $length_of_codeline = length( $code_line );
    if ( $length_of_codeline > 80 )
    {
       if ( $code_line =~
m|class(\s)+([a-zA-z])+(\w)*(\s)+:(\s)+public(\s)+([a-zA-z])+(\w)*<[a-zA-Z](\w)+>|
)
       {
            # At this point, I know I've found the line, I need to
            # split it somehow.

               $code_line =~ s/:\s*/:\n    /;

       }
    }
}

This code identifies the line in question, but having done so, I am not
sure how to split it into two lines (at the colon).  Can anyone suggest
how I'd do that?
