Hi all,

I was wondering if anyone knew how to get emacs to turn code like this:
Code:

#indef _SOMETHING_
typedef struct {
float a;
float b;
};
#endif


into this:

Code:

#indef _SOMETHING_
typedef struct {
     float a;
     float b;
};
#endif



So far, I can't seem to get it to indent what is between the preprocessor directives, and I don't know what that would be called in elisp.

Thanks in advance!

I just typed your example in, and it did exactly what you want.

Are you in C mode? If you start typing in the scratch buffer, it won't know you have a C file unless you set it (<meta>-x c-mode). Alternatively, if you start a new file, use "Visit New File" (C-x C-f) and name the file.

I can share my .emacs with you if that helps, but I don't have anything there which changes the default behaviour of the C-mode. I am using emacs 2.24.13.

edit: just thought - the other thing which screws up auto indenting is errors further up the file (assuming this is not at the top)

Thanks for the reply! Actually, I just restarted it and it worked as well. I don't know what was messed up :/
