I'm fixing up a large, old, crufty project and want to introduce broad changes carefully, both because it will cause merge problems and because the old, crufty project contributors will get upset. At this point I just want to fix the indentation. Braces, comments... leave them all be for now.
Every tool I've tried (bcpp, uncrustify and GNU indent) all have their own ideas about how code should be formatted and I have to spend a lot of time figuring out how to turn them off, if they can be turned off. I also tried the Universal Indent GUI to configure them, but they still reformatted things I didn't ask for.
I need a C code beautifier that by default does nothing. Everything feature has to be turned on. Alternatively, I need a config file for one of the C beautifiers which turns everything off.
