Linux Coding Style
Formatting Tools
Code generally has to follow the Linux coding style to be accepted. Basically there are two tools for formatting the code: indent and astyle
indent
The indent program, an excellent GNU utility found on most Linux systems, formats source according to given rules. Refer to linux.die.net/man/1/indent
The default settings are for the GNU coding style, which is not too pretty.
To get the utility to follow the Linux kernel style, the simple usage is : indent -kr -i8 -ts8 -sob -l80 -ss -bs -psl <file>
For details, below setting is used:
-nbad -bap -nbc -bbo -hnl -br -brs -c33 -cd33 -ncdb -ce -ci4 -cli0 -d0 -di1 -nfc1 -i8 -ip0 -l80 -lp -npcs -nprs -npsl -sai -saf -saw -ncs -nsc -sob -nfca -cp33 -ss -ts8 -il1
