C++/Java/C modes

C++/Java/C modes

[David Rasmussen]

Two questions:

1) How do change it so that when I press enter on a line, the cursor is 
already at the natural indentation point with spaces inserted before. 
Example:

int main()
{
   std::cout << "Hello, world!" << std::endl; <pressing enter>
<cursor is normally here>
   <I want it here>

2) How can I change the auto indentation style so that instead of

   if (whatever) <pressing enter>
<pressing tab, which shouldn't be necesary, if I get a good answer to 
question 1>
     <cursor is here!>
   <I want it here>

I guess the last question is about using the

   if (whatever) {
     blabla
   }

style. I (want to) use the

   if (whatever)
   {
     blabla
   }

style.

Help? Maybe I should just give in and go with the flow and use the short 
style.

Bind RET to the function newline-and-indent.

You will find the answer to this in the CC Mode manual, which is part
of a standard Emacs distribution.  There's a chapter there which
explains how to customize indentation interactively.

Don't give in!  The whole point of emacs is that it does what you
want.

For indentation, see the manual under "cc-mode" "built-in styles".

Start with one of the built in styles.  Then, if it's not exactly
right, the manual tells you how to tweak it.

Does [RET] work these days?  It might fail on older Emacsen.

I suggest the kbd syntax, as surely you all know.
