code beautification

code beautification

[Thomas Ruschival]

I got a lot of old code that was produced by some IDE. 
the IDE used this indentation style
if(1>2)
{
	printf("Hello World!");
}

I personally prefer the K&R c-style over this and furthermore I have the habit of putting curly braces after each if,for,while,do I don't like code like 
if (2<3)
	printf("hello world");

My problem is now I don't know how to build a regexp that works over several lines with backrefs.

The "missing" Curly Braces are not important but changing the syle would be nice. 

Anyone an idea how to reformat code in that way?

What about indent?  This is not an emacs program, though.

Well this is of course the default c-style on my system but already written code will not be reformatted if I use indent-region. it will be reindented but linebreake before the curlybrace are not undone.

Thanks alot, I never used indent with lots of switches but now it has become my best friend.

It seems that you solved your problem using the indent(1) program, which 
is  nice.  But if I want to do this kind of complex substitution in 
Emacs, I use macros.  If you're not familiar with them, I'd recommend 
reading the relevant section of the manual.  Emacs macros are really 
easier than they sound, and very useful.

Also, consider learning some elisp.  I find that a quick function in the 
scratch buffer is sometimes the simplest way of accomplishing a task.
