Formatting code text

Formatting code text

[une]

When writing code in C++ or Java I notice that I can get the code all nicley
aligned and indented correctly by simply adding a comment at the end of each
line of code. As you enter the //, the line of code moves to its correct
alignment. What I have been doing is writing my code and periodically
tidying it up by adding // at the end of every line of code. My question is,
can I speed this aligning and indenting process up by formatting the entire
file using one command? Emacs obviously knows how much each line should be
indented, but doing it one line at a time by adding // is laborious.
 
PS - I did not mean to cross post, my first post was in the Gnu Emacs forum.
Not sure how this website works yet. Sorry.

Sounds like you are talking about Meta-Control-Q (in C++ mode but  
probably in Java mode as well).

Use it when you are sitting on top of, for example, an open curly  
brace for a function.  Emacs will then reformat the whole function.

I would also suggest doing "apropos" (usually hooked to Control-H a)  
c-indent

There is a whole bunch of ways to do it.  I find some of them work  
better than others (at least in older emacs versions)

Just in case you don't know... If you find a function that you like  
and want to see if it is connected to a key, do C-h, w.  You will be  
prompted for the function in the mini-buffer.  When you complete it  
and hit return, it will tell you all the places you can get to that  
function.

Hitting TAB does that as well, in a less roundabout way.

Take a look at indent-region as well.
