Rearranging badly styled C code

Question

I've got around 12,000 lines of badly styled C code, e.g.

initholeend=(mm_footer *) (end-sizeof(mm_footer));
initholeend->magic=MM_MAGIC;
initholestart->used+=amount;

What I'd like to do is automatically adding spaces around all binary operands and assigments:

initholeend = (mm_footer *) (end - sizeof(mm_footer));
initholeend->magic = MM_MAGIC;
initholestart->used += amount;

Is there any recommended tool to do so?

Thanks in advance.

Answer 1

astyle isn't bad.

Answer 2

I would like to recommend you uncrustify. I am quite satisfied with that code beautifier and provides good results for even more programming languages.
