tidy up code

tidy up code

[Umar]

Hi,

I am new to emacs. I want to tidy up my code so that it is more
readable. For example:

int main(void)
{
  int a = 1;
     if (a == 1)
   cout << "true" << endl;
  else
        cout << "false" << endl;
    return 0;
       }

to become

int main(void)
{
  int a = 1;
  if (a == 1)
    cout << "true" << endl;
  else
    cout << "false" << endl;
  return 0;
}

No success. I press Ctrl+Shift+m and then key \. Then the \ character
appears.

I'm totally new to emacs. Can't I just select it using mouse, and then
press some key combination?
TIA

I use the command i.e. M-x indent-region because the key short cut do
not (always) work for me.

Still no success. Here is the result:

int main(void)
{
int a = 1				;
if (a == 1)
cout << "true" << endl			;
else
cout << "false" << endl			;
return 0
}

As you are new to Emacs I'm assuming you are not used to the C-M-<x>
notation.  Note that this does not mean Control + Capital M then \

C, M and S are modifier keys and you press the required ones at the same
time.

C is control.
M is meta (alt on PCs).
S is shift.

Thus, C-M-\ is control + meta (alt) + backslash at the same time.

Thank you Martin. Yes I'm new to Emacs and confused with it. I've tried to
press control+alt+\ as you told me. Here is the result:

   
   int main(void)
   {
     int a = 1;
         if (a == 1)
	  cout << "true" << endl;
	       else
	         cout << "false" << endl;
		 return 0
		      }

I've also tried M-x indent-region and other indent command, but still no
success.

You have to give a hint to emacs that you want to format a c++ file.
You do that by naming the file before you try and format it.

Go to the file menu and click on the menu item 'Visit new File' go to
the directory you want to save your file, and type in your file name
(test.cpp) and click the open button.

Now paste your code into emacs.

Once emacs has a hint on what type of file it is formatting, then
it can format it.

Note that you don't really need to name the file with the usual
extension for the file format. You can tell emacs that you're editing a
C++ file with "M-x c++-mode", despite of its name.

I strongly recommend reading the emacs tutorial (C-h t) if you didn't
already.

Thank you. That also helps.

I have. Still it is not easy to comprehend though.
