Indent is a powerful application developed by the GNU project, designed to format and change the appearance of C code. Indent will insert or delete whitespace characters to make your C code easier to read. It supports several code styles, including:
- GNU indent style (which is the default, or indent -gnu)
- Kernighan & Ritchie indent style (invoked with indent -kr)
- original Berkeley indent style (invoked with indent -orig)
Thus, to indent a C source file using the Kernighan & Ritchie style, one would use:
indent -kr source.c
Have a look at the screenshots below:
Notice that indent is developed to work with C code, not C++; also, it will try to cope with invalid code too.Source URL: http://ashesgarrett.blogspot.com/2009/12/tip-of-day-format-c-code-using-indent.html
