DESCRIPTION
indent is a C program formatter. It reformats the C program in the in‐
put-file according to the switches. The switches which can be specified
are described below. They may appear before or after the file names.
Note: if you only specify an input-file, the formatting is done "in-
place", that is, the formatted file is written back into input-file and
a backup copy of input-file is written in the current directory. If in‐
put-file is named /blah/blah/file, the backup file is named file.BAK.
If output-file is specified, indent checks to make sure it is different
from input-file.
OPTIONS
The options listed below control the formatting style imposed by in‐
dent.
-bacc,-nbacc
If -bacc is specified, a blank line is forced around every condi‐
tional compilation block. For example, in front of every #ifdef and
after every #endif. Other blank lines surrounding these will be
swallowed. Default: -nbacc.
-bad,-nbad
If -bad is specified, a blank line is forced after every block of
declarations. Default: -nbad.
-bap,-nbap
If -bap is specified, a blank line is forced after every procedure
body. Default: -nbap.
-bbb,-nbbb
If -bbb is specified, a blank line is forced before every block
comment. Default: -nbbb.
-bc,-nbc
If -bc is specified, then a NEWLINE is forced after each comma in a
declaration. -nbc turns off this option. Default: -bc.
-br,-bl
Specifying -bl lines up compound statements like this:
if (...)
{
code
}
Specifying -br (the default) makes them look like this:
if (...) {
code
}
-bs,-nbs
Enable (disable) the forcing of a blank after sizeof. Some people
believe that sizeof should appear as though it were a procedure
call (-nbs, the default) and some people believe that since sizeof
is an operator, it should always be treated that way and should al‐
ways have a blank after it.
-cn
The column in which comments on code start. The default is -c33.
-cdn
The column in which comments on declarations start. The default is
for these comments to start in the same column as those on code.
-cdb,-ncdb
Enable (disable) the placement of comment delimiters on blank
lines. With this option enabled, comments look like this:
/*
* this is a comment
*/
Rather than like this:
/* this is a comment */
This only affects block comments, not comments to the right of
code. Default: -cdb.
-ce,-nce
Enables (disables) forcing else's to cuddle up to the immediately
preceding `}'. Default: -ce.
-cin
Sets the continuation indent to be the value of n. Continuation
lines will be indented the value of n from the beginning of the
first line of the statement. Parenthesized expressions have extra
indentation added to indicate the nesting, unless -lp is in effect.
-ci defaults to the same value as -i.
-clin
Cause case labels to be indented n tab stops to the right of the
containing switch statement. -cli0.5 causes case labels to be in‐
dented half a tab stop. Default: -cli0.
-dn
Control the placement of comments which are not to the right of
code. Default: -d1 means that such comments are placed one indenta‐
tion level to the left of code. Specifying -d0 lines up these com‐
ments with the code. See the section on comment indentation below.
-din
Specify the indentation, in character positions, from a declaration
keyword to the following identifier. Default: -di16.
-dj,-ndj
-dj left justifies declarations. -ndj indents declarations the same
as code. Default: -ndj.
-ei,-nei
If -ei is enabled, ifs following elses will have the same indenta‐
tion as the preceding if statement. If it is disabled, ifs follow‐
ing elses will be indented one extra level. Default: -ei.
-eei,-neei
If -eei is specified, an extra expression indent is applied on con‐
tinuation lines of the expression part of if() and while(). These
continuation lines will be indented one extra level -- twice in‐
stead of just once. This is to avoid the confusion between the con‐
tinued expression and the statement that follows the if() or
while(). Default: -neei.
-fc1,-nfc1
Enables (disables) the formatting of comments that start in column
1. Often, comments whose leading `/' is in column 1 have been care‐
fully hand formatted by the programmer. In such cases, -nfc1 should
be used. Default: -fc1.
-in
The number of spaces for one indentation level. The default is one
tab stop, -i8.
-ip,-nip
Enables (disables) the indentation of parameter declarations from
the left margin. Default: -ip .
-ln
Maximum length of an output line with a trailing comment. Default:
-l78.
-lcn
Sets the line length for block comments to n. It defaults to being
the same as the usual line length as specified with -l.
-lp,-nlp
Lines up code surrounded by parenthesis in continuation lines. If a
line has a left parenthesis which is not closed on that line, then
continuation lines will be lined up to start at the character posi‐
tion just after the left parenthesis. For example, here is how a
piece of continued code looks with -nlp in effect:
p1 = first_procedure(second_procedure(p2, p3),
third_procedure(p4, p5));
With -lp in effect (the default) the code looks somewhat clearer:
p1 = first_procedure(second_procedure(p2, p3),
third_procedure(p4, p5));
Inserting a couple more NEWLINE characters we get:
p1 = first_procedure(second_procedure(p2, p3),
third_procedure(p4, p5));
This example was generated with -lp.
-npro
Ignore the profile files, ./.indent.pro and ~/.indent.pro.
-pcs , -npcs
If true (-pcs) all procedure calls and declarations in the source
code will have a space inserted between the name and the '('. De‐
fault: -npcs.
-psl , -npsl
If true (-psl) the names of procedures being defined are placed in
column 1 -- their types, if any, will be left on the previous
lines. Default: -psl.
-sc,-nsc
Enables (disables) the placement of asterisks (`*'s) at the left
edge of all comments. Default: -sc.
-sob,-nsob
If -sob is specified, indent will swallow optional blank lines. You
can use this to get rid of blank lines after declarations. Default:
-nsob.
-st
indent takes its input from the standard input, and put its output
to the standard output.
-T typename
Add typename to the list of type keywords. Names accumulate: -T can
be specified more than once. You need to specify all the typenames
that appear in your program that are defined by typedefs -- nothing
will be harmed if you miss a few, but the program won't be format‐
ted as nicely as it should. This sounds like a painful thing to
have to do, but it is really a symptom of a problem in C: typedef
causes a syntactic change in the language and indent cannot find
all typedefs.
-troff
Causes indent to format the program for processing by troff. It
will produce a fancy listing in much the same spirit as vgrind. If
the output file is not specified, the default is standard output,
rather than formatting in place. The usual way to get a troffed
listing is with the command
indent -troff program.c | troff -mindent
-v,-nv
-v turns on "verbose" mode, -nv turns it off. When in verbose mode,
indent reports when it splits one line of input into two or more
lines of output, and gives some size statistics at completion. De‐
fault: -nv.
USAGE
You may set up your own "profile" of defaults to indent by creating a
file called .indent.pro in either your login directory or the current
directory and including whatever switches you like. An .indent.pro in
the current directory takes precedence over the one in your login di‐
rectory. If indent is run and a profile file exists, then it is read to
set up the program's defaults. Switches on the command line, though,
always override profile switches. The switches should be separated by
SPACE, TAB, or NEWLINE characters.
Comments
Boxed
indent assumes that any comment with a dash or star immediately af‐
ter the start of comment (that is, `/*-'or`/**') is a comment sur‐
rounded by a box of stars. Each line of such a comment is left un‐
changed, except that its indentation may be adjusted to account for
the change in indentation of the first line of the comment.
Straight text
All other comments are treated as straight text. indent fits as
many words (separated by SPACE, TAB, or NEWLINE characters) on a
line as possible. Blank lines break paragraphs.
Comment indentation
If a comment is on a line with code it is started in the comment col‐
umn, which is set by the -cn command line parameter. Otherwise, the
comment is started at n indentation levels less than where code is cur‐
rently being placed, where n is specified by the -dn command line para‐
meter. If the code on a line extends past the comment column, the com‐
ment starts further to the right, and the right margin may be automati‐
cally extended in extreme cases.
Preprocessor lines
In general, indent leaves preprocessor lines alone. The only reformat‐
ting that it will do is to straighten up trailing comments. It leaves
imbedded comments alone. Conditional compilation (#ifdef...#endif) is
recognized and indent attempts to correctly compensate for the syntac‐
tic peculiarities introduced.
C syntax
indent understands a substantial amount about the syntax of C, but it
has a "forgiving" parser. It attempts to cope with the usual sorts of
incomplete and misformed syntax. In particular, the use of macros like:
#define forever for(;;)
is handled properly.
/*INDENT OFF*/ /*INDENT ON*/
All text between these two comments gets left alone. Therefore, when
you put source code between these comments, it will not be affected by
the reformatting.

BUGS
A common mistake that often causes grief is typing:
indent *.c
to the shell in an attempt to indent all the C programs in a directory.
