Question

I have so much C code. I need to edit that code to follow some coding line tips. So I need to limit all my C code to a maximum of 80 characters per line. Instead of editing each line of code, how can I perform this transformation with a tool/IDE/script?

Answer 1

One such tool I know of is indent on Linux. It can be used to format your code in any style. Example from the man page:

The Linux style is used in the linux kernel code and drivers:

indent test/metabolism.c -linux

Another switch, more specific to your questions:

-ln, –line-lengthn

Set maximum line length for non-comment lines to n.
