indent is a Unix utility that reformats C and C++ code in a user-defined indentation style and coding style. Support for C++ code is minimal.[3]

The original version of indent was written by David Willcox at the University of Illinois in November 1976. It was incorporated into 4.1BSD in October 1982.[4] GNU indent was first written by Jim Kingdon in 1989. The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities.[5]

Examples of usage

[edit]

The following command

$ indent -st -bap -bli0 -i4 -l79 -ncs -npcs -npsl -fca -lc79 -fc1 -ts4 some_file.c

indents some_file.c in a style resembling BSD/Allman style and writes the result to the standard output.

GNU indent

[edit]

GNU indent is the GNU Project's version of indent. A different indentation style, the GNU style, is used by default.[6]
