Linux Kernel has a script lindent that helps you format your code in a good code style.
For example:// Usr/src/linux-headers-2.6.22-14/scripts/lindent Common settings:
Indent-NPRO-Kr-I4-ts4-sob-L80-SS-bl-Bli 0 (I like this style)
Parameter description:
-NPRO or -- ignore-profile do not read indent's configuration file. indent. Pro.
-Kr specifies the format of kernighan & Ritchie. It can be changed to-orig or BSD.
-I4 -- indent-level: set the number of cells to 4.
-Ts4: Set the tab Length
-Sob or -- swallow-optional-blank-lines Delete unnecessary blank lines.
-Line feed of L80 Code exceeding 80
-SS or -- space-special-semicolon if the for section contains only one line, add a space before the semicolon.
-NCs or -- no-space-after-casts should not be empty after cast.
-BL {branch display
-Bli 0 parentheses indent to 0 I usually use: Indent-NPRO-nip-NLP-npsl-I4-ts4-sob-L200-SS-bl-Bli 0Code File Name
Function Description: adjusts the format of the original C code file.
