|
# This script uses the Linux 'indent' utility to re-format C source files
|
|
# to match the coding style that I use. It differs from the NuttX coding
|
|
# style in that:
|
|
#
|
|
# 1. I normally put the trailing */ of a multi-line comment on a separate
|
|
# line. If your C file already has properly formatted comments then
|
|
# using -nfca instead of -fca eliminates that bad behavior
|
|
# 2. I usually align things vertically (like '=' in assignments),
|
|
# 3. indent.sh puts a bogus blank line at the top of the file,
|
|
# 4. I don't like the way it handles nested conditional compilation
|
|
# intermixed with code. I prefer the preprocessor conditiona tests
|
|
# be all right justified in that case.
|
|
# 5. I also indent brackets differently on structures than does this script.
|
|
# 6. I normally use no spaces in casts. indent.sh adds spaces in casts like
|
|
# "(FAR void *)&foo" becomes "(FAR void *) & foo".
|
|
# 7. When used with header files, the initial idempotence conditional test
|
|
# causes all preprecessor directives to be indented in the file. So for
|
|
# header files, you will need to substitute "^# " with "#" in the
|
|
# converted header file.
|
|
#
|
|
# You will manually need to check for the issues listed above after
|
|
# performing the conversion.
