<p>The <code>indent</code> program
can be used to make code easier to read. It can also convert from one
style of writing C to another.
</p>
<p><code>indent</code> understands a substantial amount about the syntax of C,
but it also attempts to cope with incomplete and misformed syntax.
</p>
<p>In version 1.2 and more recent versions, the GNU style of indenting is
the default.

<h2 class="section">1.1 Invoking <code>indent</code></h2>
<a name="index-Invoking-indent"></a>
<a name="index-Starting-indent"></a>
<a name="index-Beginning-indent"></a>
<p>As of version 1.3, the format of the <code>indent</code> command is:
</p>
<div class="example">
<pre class="example">
indent [<var>options</var>] [<var>input-files</var>]
indent [<var>options</var>] [<var>single-input-file</var>] [-o <var>output-file</var>]
</pre></div>
<p>This format is different from earlier versions and other versions of
<code>indent</code>.
</p>
<p>In the first form, one or more input files are specified. <code>indent</code>
makes a backup copy of each file, and the original file is replaced with
its indented version. See section <a href="#Backup-files">Backup Files</a>, for an explanation of how
backups are made.
</p>
<a name="index-Output-File-Specification"></a>
<a name="index-_002do"></a>
<a name="index-_002d_002doutput_002dfile"></a>
<p>In the second form, only one input file is specified. In this case, or
when the standard input is used, you may specify an output file after
the ‘<samp>-o</samp>’ option.
</p>
<a name="index-Standard-Output"></a>
<a name="index-_002dst"></a>
<a name="index-_002d_002dstandard_002doutput"></a>
<p>To cause <code>indent</code> to write to standard output, use the ‘<samp>-st</samp>’
option. This is only allowed when there is only one input file, or when
the standard input is used.
</p>
<a name="index-Using-Standard-Input"></a>
<p>If no input files are named, the standard input is read for input.
Also, if a filename named ‘<samp>-</samp>’ is specified, then the standard input
is read.
</p>
<p>As an example, each of the following commands will input the program
‘<tt>slithy_toves.c</tt>’ and write its indented text to
‘<tt>slithy_toves.out</tt>’:
</p>
<div class="example">
<pre class="example">
indent slithy_toves.c -o slithy_toves.out
indent -st slithy_toves.c > slithy_toves.out
cat slithy_toves.c | indent -o slithy_toves.out
</pre></div>
<a name="index-Long-options_002c-use-of"></a>
<p>Most other options to <code>indent</code> control how programs are formatted.
As of version 1.2, <code>indent</code> also recognizes a long name for each
option name. Long options are prefixed by either ‘<samp>--</samp>’ or
‘<samp>+</samp>’.
<a name="DOCF1" href="#FOOT1">(1)</a>
In most of this document,
the traditional, short names are used for the sake of brevity.
See section <a href="#Option-Summary">Option Summary</a>, for a list of options, including both long and
short names.
</p>
<p>Here is another example:
</p>
<div class="example">
<pre class="example">indent -br test/metabolism.c -l85
</pre></div>
<p>This will indent the program ‘<tt>test/metabolism.c</tt>’ using the
‘<samp>-br</samp>’ and ‘<samp>-l85</samp>’ options, write the output back to
‘<tt>test/metabolism.c</tt>’, and write the original contents of
‘<tt>test/metabolism.c</tt>’ to a backup file in the directory ‘<tt>test</tt>’.
</p>
<p>Equivalent invocations using long option names for this example would
be:
</p>
<div class="example">
<pre class="example">
indent --braces-on-if-line --line-length185 test/metabolism.c
indent +braces-on-if-line +line-length185 test/metabolism.c
</pre></div>
<a name="index-_002eindent_002epro-file"></a>
<a name="index-Initialization-file"></a>
<a name="index-_002dnpro"></a>
<a name="index-_002d_002dignore_002dprofile"></a>
<p>If you find that you often use <code>indent</code> with the same options, you
may put those options into a file named ‘<tt>.indent.pro</tt>’.
<code>indent</code> will look for a profile file in three places. First it will check
the environment variable <code>INDENT_PROFILE</code>. If that exists its value
is expected to name the file that is to be used. If the environment variable does
not exist, indent looks for ‘<tt>.indent.pro</tt>’ in the current directory
and use that if found. Finally <code>indent</code> will search
your home directory for ‘<tt>.indent.pro</tt>’ and use that file if it is
found. This behaviour is different from that of other versions of
<code>indent</code>, which load both files if they both exist.
</p>
<p>The format of ‘<tt>.indent.pro</tt>’ is simply a list of options, just as
they would appear on the command line, separated by white space (tabs,
spaces, and newlines). Options in ‘<tt>.indent.pro</tt>’ may be surrounded by C
or C++ comments, in which case they are ignored.
</p>
<p>Command line switches are handled <em>after</em> processing
‘<tt>.indent.pro</tt>’. Options specified later override arguments
specified earlier, with one exception: Explicitly specified options
always override background options (see section <a href="#Common-styles">Common styles</a>). You can
prevent <code>indent</code> from reading an ‘<tt>.indent.pro</tt>’ file by
specifying the ‘<samp>-npro</samp>’ option.

<h2 class="section">1.2 Backup Files</h2>
<a name="index-backup-files"></a>
<p>As of version 1.3, GNU <code>indent</code> makes GNU-style backup files, the
same way GNU Emacs does. This means that either <em>simple</em> or
<em>numbered</em> backup filenames may be made.
</p>
<p>Simple backup file names are generated by appending a suffix to the
original file name. The default for this suffix is the
one-character string ‘<tt>~</tt>’ (tilde). Thus, the backup file for
‘<tt>python.c</tt>’ would be ‘<tt>python.c~</tt>’.
</p>
<p>Instead of the default, you may specify any string as a suffix by
setting the environment variable <code>SIMPLE_BACKUP_SUFFIX</code> to
your preferred suffix.
</p>
<p>Numbered backup versions of a file ‘<tt>momeraths.c</tt>’ look like
‘<tt>momeraths.c.~23~</tt>’, where 23 is the version of this particular
backup. When making a numbered backup of the file ‘<tt>src/momeraths.c</tt>’,
the backup file will be named ‘<tt>src/momeraths.c.~<var>V</var>~</tt>’, where
<var>V</var> is one greater than the highest version currently existing in
the directory ‘<tt>src</tt>’. The environment variable <code>VERSION_WIDTH</code>
controls the number of digits, using left zero padding when necessary.
For instance, setting this variable to "2" will lead to the backup
file being named ‘<tt>momeraths.c.~04~</tt>’.
</p>
<p>The type of backup file made is controlled by the value of the
environment variable <code>VERSION_CONTROL</code>. If it is the string
‘<samp>simple</samp>’, then only simple backups will be made. If its value is
the string ‘<samp>numbered</samp>’, then numbered backups will be made. If its
value is ‘<samp>numbered-existing</samp>’, then numbered backups will be made if
there <em>already exist</em> numbered backups for the file being indented;
otherwise, a simple backup is made. If <code>VERSION_CONTROL</code> is not
set, then <code>indent</code> assumes the behaviour of
‘<samp>numbered-existing</samp>’.
</p>
<p>Other versions of <code>indent</code> use the suffix ‘<tt>.BAK</tt>’ in naming
backup files. This behaviour can be emulated by setting
<code>SIMPLE_BACKUP_SUFFIX</code> to ‘<samp>.BAK</samp>’.
</p>
<p>Note also that other versions of <code>indent</code> make backups in the
current directory, rather than in the directory of the source file as
GNU <code>indent</code> now does.

<h2 class="section">1.3 Common styles</h2>
<p>There are several common styles of C code, including the GNU style, the
Kernighan & Ritchie style, and the original Berkeley style. A style may
be selected with a single <em>background</em> option, which specifies a set
of values for all other options. However, explicitly specified options
always override options implied by a background option.
</p>
<a name="index-GNU-style"></a>
<a name="index-_002dgnu"></a>
<a name="index-_002d_002dgnu_002dstyle"></a>
<p>As of version 1.2, the default style of GNU <code>indent</code> is the GNU
style. Thus, it is no longer necessary to specify the option
‘<samp>-gnu</samp>’ to obtain this format, although doing so will not cause an
error. Option settings which correspond to the GNU style are:
</p>
<div class="example">
<pre class="example">-nbad -bap -nbc -bbo -bl -bli2 -bls -ncdb -nce -cp1 -cs -di2
-ndj -nfc1 -nfca -hnl -i2 -ip5 -lp -pcs -nprs -psl -saf -sai
-saw -nsc -nsob
</pre></div>
<p>The GNU coding style is that preferred by the GNU project. It is the
style that the GNU Emacs C mode encourages and which is used in the C
portions of GNU Emacs. (People interested in writing programs for
Project GNU should get a copy of <cite>The GNU Coding Standards</cite>, which
also covers semantic and portability issues such as memory usage, the
size of integers, etc.)
</p>
<a name="index-Kernighan-_0026-Ritchie-style"></a>
<a name="index-_002dkr"></a>
<a name="index-_002d_002dk_002dand_002dr_002dstyle"></a>
<p>The Kernighan & Ritchie style is used throughout their well-known book
<cite>The C Programming Language</cite>. It is enabled with the ‘<samp>-kr</samp>’
option. The Kernighan & Ritchie style corresponds to the following set
of options:
</p>
<div class="example">
<pre class="example">-nbad -bap -bbo -nbc -br -brs -c33 -cd33 -ncdb -ce -ci4 -cli0
-cp33 -cs -d0 -di1 -nfc1 -nfca -hnl -i4 -ip0 -l75 -lp -npcs
-nprs -npsl -saf -sai -saw -nsc -nsob -nss
</pre></div>
<p>Kernighan & Ritchie style does not put comments to the right of code in
the same column at all times (nor does it use only one space to the
right of the code), so for this style <code>indent</code> has arbitrarily
chosen column 33.
</p>
<a name="index-Berkeley-style"></a>
<a name="index-Original-Berkeley-style"></a>
<a name="index-_002dorig"></a>
<a name="index-_002d_002doriginal"></a>
<p>The style of the original Berkeley <code>indent</code> may be obtained by
specifying ‘<samp>-orig</samp>’ (or by specifying ‘<samp>--original</samp>’, using the
long option name). This style is equivalent to the following settings:
</p>
<div class="example">
<pre class="example">-nbad -nbap -bbo -bc -br -brs -c33 -cd33 -cdb -ce -ci4 -cli0
-cp33 -di16 -fc1 -fca -hnl -i4 -ip4 -l75 -lp -npcs -nprs -psl
-saf -sai -saw -sc -nsob -nss -ts8
</pre></div>
<a name="index-Linux-style"></a>
<a name="index-_002dlinux"></a>
<a name="index-_002d_002dlinux_002dstyle"></a>
<p>The Linux style is used in the linux kernel code and drivers. Code
generally has to follow the Linux coding style to be accepted.
This style is equivalent to the following settings:
</p>
<div class="example">
<pre class="example">-nbad -bap -nbc -bbo -hnl -br -brs -c33 -cd33 -ncdb -ce -ci4
-cli0 -d0 -di1 -nfc1 -i8 -ip0 -l80 -lp -npcs -nprs -npsl -sai

<h2 class="section">1.4 Blank lines</h2>
<a name="index-Blank-lines"></a>
<p>Various programming styles use blank lines in different places.
<code>indent</code> has a number of options to insert or delete blank lines in
specific places.
</p>

<a name="Comments-1"></a>
<h2 class="section">1.5 Comments</h2>
<a name="index-Comments"></a>
<p><code>indent</code> formats both C and C++ comments. C comments are begun with
‘<samp>/*</samp>’, terminated with ‘<samp>*/</samp>’ and may contain newline characters.
C++ comments begin with the delimiter ‘<samp>//</samp>’ and end at the newline.
</p>
<p><code>indent</code> handles comments differently depending upon their context.
<code>indent</code> attempts to distinguish between comments which follow
statements, comments which follow declarations, comments following
preprocessor directives, and comments which are not preceded by code of
any sort, i.e., they begin the text of the line (although not
necessarily in column 1).
</p>
<p><code>indent</code> further distinguishes between comments found outside of
procedures and aggregates, and those found within them. In particular,
comments beginning a line found within a procedure will be indented to
the column at which code is currently indented. The exception to this
is a comment beginning in the leftmost column; such a comment is output
at that column.
</p>
<p><code>indent</code> attempts to leave <em>boxed comments</em> unmodified. The
general idea of such a comment is that it is enclosed in a rectangle or
“box” of stars or dashes to visually set it apart. More precisely,
boxed comments are defined as those in which the initial ‘<samp>/*</samp>’ is
followed immediately by the character ‘<samp>*</samp>’, ‘<samp>=</samp>’, ‘<samp>_</samp>’, or
‘<samp>-</samp>’, or those in which the beginning comment delimiter (‘<samp>/*</samp>’)
is on a line by itself, and the following line begins with a ‘<samp>*</samp>’ in
the same column as the star of the opening delimiter.
</p>
<p>Examples of boxed comments are:
</p>
<div class="example">
<pre class="example">/**********************
* Comment in a box!! *
**********************/
/*
* A different kind of scent,
* for a different kind of comment.
*/
</pre></div>
<p><code>indent</code> attempts to leave boxed comments exactly as they are found
in the source file. Thus the indentation of the comment is unchanged,
and its length is not checked in any way. The only alteration made is
that an embedded tab character may be converted into the appropriate
number of spaces.
</p>
<p>If the ‘<samp>-bbb</samp>’ option is specified, all such boxed comments will be
preceded by a blank line, unless such a comment is preceded by code.
</p>
<a name="index-_002dfca"></a>
<a name="index-_002d_002dformat_002dall_002dcomments"></a>
<a name="index-_002dnfca"></a>

<a name="index-_002dnfc1"></a>
<a name="index-_002d_002ddont_002dformat_002dfirst_002dcolumn_002dcomments"></a>
<p>Comments which are not boxed comments may be formatted, which means that
the line is broken to fit within a right margin and left-filled with
whitespace. Single newlines are equivalent to a space, but blank lines
(two or more newlines in a row) are taken to mean a paragraph break.
Formatting of comments which begin after the first column is enabled
with the ‘<samp>-fca</samp>’ option. To format those beginning in column one,
specify ‘<samp>-fc1</samp>’. Such formatting is disabled by default.
</p>
<p>The right margin for formatting defaults to 78, but may be changed with
the ‘<samp>-lc</samp>’ option. If the margin specified does not allow the
comment to be printed, the margin will be automatically extended for the
duration of that comment. The margin is not respected if the comment is
not being formatted.
</p>
<a name="index-_002ddn"></a>
<a name="index-_002d_002dline_002dcomments_002dindentationn"></a>
<p>If the comment begins a line (i.e., there is no program text to its
left), it will be indented to the column it was found in unless the
comment is within a block of code. In that case, such a comment will be
aligned with the indented code of that block (unless the comment began
in the first column). This alignment may be affected by the ‘<samp>-d</samp>’
option, which specifies an amount by which such comments are moved to
the <em>left</em>, or unindented. For example, ‘<samp>-d2</samp>’ places comments
two spaces to the left of code. By default, comments are aligned with
code, unless they begin in the first column, in which case they are left
there by default — to get them aligned with the code, specify ‘<samp>-fc1</samp>’.

<a name="index-_002ddj"></a>
<a name="index-_002dndj"></a>
<p>Comments to the right of code will appear by default in column 33.
This may be changed with one of three options. ‘<samp>-c</samp>’ will specify
the column for comments following code, ‘<samp>-cd</samp>’ specifies the
column for comments following declarations, and ‘<samp>-cp</samp>’ specifies
the column for comments following preprocessor directives <code>#else</code>
and <code>#endif</code>. ‘<samp>-dj</samp>’ together with ‘<samp>-cd0</samp>’ can be used
to suppress alignment of comments to the right of declarations, causing the
comment to follow one tabstop from the end of the declaration. Normally ‘<samp>-cd0</samp>’
causes ‘<samp>-c</samp>’ to become effective.
</p>
<p>If the code to the left of the comment exceeds the beginning column,
the comment column will be extended to the next tabstop column past
the end of the code, or in the case of preprocessor directives, to one
space past the end of the directive. This extension lasts only for
the output of that particular comment.

<p>The ‘<samp>-cdb</samp>’ option places the comment delimiters on blank lines.
Thus, a single line comment like <code>/* Loving hug */</code> can be
transformed into:
</p>
<div class="example">
<pre class="example">/*
Loving hug
*/
</pre></div>

<p>Stars can be placed at the beginning of multi-line comments with the
‘<samp>-sc</samp>’ option. Thus, the single-line comment above can be
transformed (with ‘<samp>-cdb -sc</samp>’) into:
</p>
<div class="example">
<pre class="example">/*

<a name="index-_002d_002dbraces_002dafter_002dif_002dline"></a>
<p>The ‘<samp>-br</samp>’ or ‘<samp>-bl</samp>’ option specifies how to format braces.
</p>
<p>The ‘<samp>-br</samp>’ option formats statement braces like this:
</p>
<div class="example">
<pre class="example">if (x > 0) {
x--;
}
</pre></div>
<p>The ‘<samp>-bl</samp>’ option formats them like this:
</p>
<div class="example">
<pre class="example">if (x > 0)
{
x--;
}
</pre></div>
<a name="index-_002dblin"></a>
<a name="index-_002d_002dbrace_002dindentn"></a>
<p>If you use the ‘<samp>-bl</samp>’ option, you may also want to specify the
‘<samp>-bli</samp>’ option. This option specifies the number of spaces by
which braces are indented. ‘<samp>-bli2</samp>’, the default, gives the
result shown above. ‘<samp>-bli0</samp>’ results in the following:
</p>
<div class="example">
<pre class="example">if (x > 0)
{
x--;
}
</pre></div>

<a name="index-_002ddce"></a>
<a name="index-_002d_002ddont_002dcuddle_002delse"></a>
<p>If you are using the ‘<samp>-br</samp>’ option, you probably want to also use
the ‘<samp>-ce</samp>’ option. This causes the <code>else</code> in an if-then-else
construct to cuddle up to the immediately preceding ‘<samp>}</samp>’. For
example, with ‘<samp>-br -ce</samp>’ you get the following:
</p>
<div class="example">
<pre class="example">if (x > 0) {
x--;
} else {
fprintf (stderr, "...something wrong?\n");
}
</pre></div>
<p>With ‘<samp>-br -nce</samp>’ that code would appear as
</p>
<div class="example">
<pre class="example">if (x > 0) {
x--;
}
else {
fprintf (stderr, "...something wrong?\n");
}

<p>This causes the <code>while</code> in a do-while
loop to cuddle up to the immediately preceding ‘<samp>}</samp>’. For
example, with ‘<samp>-cdw</samp>’ you get the following:
</p>
<div class="example">
<pre class="example">do {
x--;
} while (x);
</pre></div>
<p>With ‘<samp>-ncdw</samp>’ that code would appear as

while (x);

<a name="index-_002dclin"></a>
<a name="index-_002d_002dcase_002dindentationn"></a>
<p>The ‘<samp>-cli</samp>’ option specifies the number of spaces that case labels
should be indented to the right of the containing <code>switch</code>
statement.
</p>
<p>The default gives code like:
</p>
<div class="example">
<pre class="example">switch (i)
{
case 0:
break;
case 1:
{
++i;
}
default:
break;
}
</pre></div>
<p>Using the ‘<samp>-cli2</samp>’ that would become:
</p>
<div class="example">
<pre class="example">switch (i)
{
case 0:
break;
case 1:
{
++i;
}
default:
break;
}
</pre></div>
<a name="index-_002dcbin"></a>
<a name="index-_002d_002dcase_002dbrace_002dindentationn"></a>
<p>The indentation of the braces below a case statement can be
controlled with the ‘<samp>-cbi<var>n</var></samp>’ option. For example,
using ‘<samp>-cli2 -cbi0</samp>’ results in:
</p>
<div class="example">
<pre class="example">switch (i)
{
case 0:
break;
case 1:
{
++i;
}
default:
break;

<a name="index-_002d_002ddont_002dspace_002dspecial_002dsemicolon"></a>
<p>If a semicolon is on the same line as a <code>for</code> or <code>while</code>
statement, the ‘<samp>-ss</samp>’ option will cause a space to be placed before
the semicolon. This emphasizes the semicolon, making it clear that the
body of the <code>for</code> or <code>while</code> statement is an empty statement.
‘<samp>-nss</samp>’ disables this feature.

<p>The ‘<samp>-pcs</samp>’ option causes a space to be placed between the name of
the procedure being called and the ‘<samp>(</samp>’ (for example, <code>puts ("Hi");</code>. The ‘<samp>-npcs</samp>’ option would give <code>puts("Hi");</code>).

<a name="index-_002dncs"></a>
<a name="index-_002d_002dno_002dspace_002dafter_002dcast"></a>
<p>If the ‘<samp>-cs</samp>’ option is specified, <code>indent</code> puts a space between
a cast operator and the object to be cast. The ‘<samp>-ncs</samp>’ ensures that there
is no space between the cast operator and the object. Remember that <code>indent</code>
only knows about the standard C data types and so cannot recognise user-defined types
in casts. Thus <code>(mytype)thing</code> is not treated as a cast.
</p>
<a name="index-_002dbs"></a>
<a name="index-_002d_002dblank_002dafter_002dsizeof"></a>
<p>The ‘<samp>-bs</samp>’ option ensures that there is a space between the

known as the ‘<samp>Bill_Shannon</samp>’ option.

<p>The ‘<samp>-prs</samp>’ option causes all parentheses to be separated with
a space from whatever is between them. For example, using ‘<samp>-prs</samp>’
results in code like:
</p>
<div class="example">
<pre class="example"> while ( ( e_code - s_code ) < ( dec_ind - 1 ) )
{
set_buf_break ( bb_dec_ind );
*e_code++ = ' ';

<a name="index-_002d_002ddeclaration_002dindentationn"></a>
<p>By default <code>indent</code> will line up identifiers, in the column
specified by the ‘<samp>-di</samp>’ option. For example, ‘<samp>-di16</samp>’ makes
things look like:
</p>
<div class="example">
<pre class="example">int foo;
char *bar;
</pre></div>
<p>Using a small value (such as one or two) for the ‘<samp>-di</samp>’ option can
be used to cause the identifiers to be placed in the first available
position; for example:
</p>
<div class="example">
<pre class="example">int foo;
char *bar;
</pre></div>
<p>The value given to the ‘<samp>-di</samp>’ option will still affect variables
which are put on separate lines from their types, for example
‘<samp>-di2</samp>’ will lead to:
</p>
<div class="example">
<pre class="example">int
foo;
</pre></div>
<a name="index-_002dbc"></a>
<a name="index-_002d_002dblank_002dlines_002dafter_002dcommas"></a>

<a name="index-_002d_002dno_002dblank_002dlines_002dafter_002dcommas"></a>
<p>If the ‘<samp>-bc</samp>’ option is specified, a newline is forced after each
comma in a declaration. For example,
</p>
<div class="example">
<pre class="example">int a,
b,
c;
</pre></div>
<p>With the ‘<samp>-nbc</samp>’ option this would look like
</p>
<div class="example">
<pre class="example">int a, b, c;
</pre></div>

<a name="index-_002d_002ddont_002dbreak_002dfunction_002ddecl_002dargs_002dend"></a>
<p>The ‘<samp>-bfda</samp>’ option causes a newline to be forced after the comma
separating the arguments of a function declaration. The arguments will
appear at one indention level deeper than the function declaration. This
is particularly helpful for functions with long argument lists.
The option ‘<samp>-bfde</samp>’ causes a newline to be forced before the closing
bracket of the function declaration. For both options the ’n’ setting is the default:
-nbdfa and -nbdfe.
</p>
<p>For
example,
</p>
<div class="example">
<pre class="example">void foo (int arg1, char arg2, int *arg3, long arg4, char arg5);
</pre></div>
<p>With the ‘<samp>-bfda</samp>’ option this would look like
</p>
<div class="example">
<pre class="example">void foo (
int arg1,
char arg2,
int *arg3,
long arg4,
char arg5);
</pre></div>
<p>With, in addition, the ‘<samp>-bfde</samp>’ option this would look like
</p>
<div class="example">
<pre class="example">void foo (
int arg1,
char arg2,
int *arg3,
long arg4,
char arg5
);

<p>The ‘<samp>-psl</samp>’ option causes the type of a procedure being defined to
be placed on the line before the name of the procedure. This style is
required for the <code>etags</code> program to work correctly, as well as some
of the <code>c-mode</code> functions of Emacs.
</p>
<a name="index-_002dT"></a>
<a name="index-Typenames"></a>
<a name="index-typedef"></a>
<p>You must use the ‘<samp>-T</samp>’
option to tell <code>indent</code> the name of all the typenames in your
program that are defined by <code>typedef</code>. ‘<samp>-T</samp>’ can be specified
more than once, and all names specified are used. For example, if your
program contains
</p>
<div class="example">
<pre class="example">typedef unsigned long CODE_ADDR;
typedef enum {red, blue, green} COLOR;
</pre></div>
<p>you would use the options ‘<samp>-T CODE_ADDR -T COLOR</samp>’.

<a name="index-_002d_002dbraces_002don_002dstruct_002ddecl_002dline"></a>
<p>The ‘<samp>-brs</samp>’ or ‘<samp>-bls</samp>’ option specifies how to format braces
in struct declarations. The ‘<samp>-brs</samp>’ option formats braces like
this:
</p>
<div class="example">
<pre class="example">struct foo {
int x;
};
</pre></div>
<p>The ‘<samp>-bls</samp>’ option formats them like this:
</p>
<div class="example">
<pre class="example">struct foo
{
int x;
};

<p>Similarly to the structure brace ‘<samp>-brs</samp>’ and ‘<samp>-bls</samp>’ options,
the function brace options ‘<samp>-brf</samp>’ or ‘<samp>-blf</samp>’ specify how to format the braces
in function definitions. The ‘<samp>-brf</samp>’ option formats braces like
this:
</p>
<div class="example">
<pre class="example">int one(void) {
return 1;
};
</pre></div>
<p>The ‘<samp>-blf</samp>’ option formats them like this:

<div class="example">
<pre class="example">int one(void)
{
return 1;
};

<a name="index-_002dnlp"></a>
<a name="index-_002d_002ddont_002dline_002dup_002dparentheses"></a>
<p>One issue in the formatting of code is how far each line should be
indented from the left margin. When the beginning of a statement such
as <code>if</code> or <code>for</code> is encountered, the indentation level is
increased by the value specified by the ‘<samp>-i</samp>’ option. For example,
use ‘<samp>-i8</samp>’ to specify an eight character indentation for each
level. When a statement is broken across two lines, the second line is
indented by a number of additional spaces specified by the ‘<samp>-ci</samp>’
option. ‘<samp>-ci</samp>’ defaults to 0. However, if the ‘<samp>-lp</samp>’ option is
specified, and 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
position just after the left parenthesis. This processing also applies
to ‘<samp>[</samp>’ and applies to ‘<samp>{</samp>’ when it occurs in initialization
lists. For example, a piece of continued code might look like this with
‘<samp>-nlp -ci3</samp>’ in effect:
</p>
<div class="example">
<pre class="example"> p1 = first_procedure (second_procedure (p2, p3),
third_procedure (p4, p5));
</pre></div>
<p>With ‘<samp>-lp</samp>’ in effect the code looks somewhat clearer:
</p>
<div class="example">
<pre class="example"> p1 = first_procedure (second_procedure (p2, p3),
third_procedure (p4, p5));
</pre></div>
<a name="index-_002dtsn"></a>
<a name="index-_002d_002dtab_002dsizen"></a>
<p>When a statement is broken in between two or more paren pairs (...),
each extra pair causes the indentation level extra indentation:
</p>
<div class="example">
<pre class="example">if ((((i < 2 &&
k > 0) || p == 0) &&
q == 1) ||
n = 0)
</pre></div>
<p>The option ‘<samp>-ip<var>N</var></samp>’ can be used to set the extra offset per paren.
For instance, ‘<samp>-ip0</samp>’ would format the above as:
</p>
<div class="example">
<pre class="example">if ((((i < 2 &&
k > 0) || p == 0) &&
q == 1) ||
n = 0)
</pre></div>
<p><code>indent</code> assumes that tabs are placed at regular intervals of both
input and output character streams. These intervals are by default 8
columns wide, but (as of version 1.2) may be changed by the ‘<samp>-ts</samp>’
option. Tabs are treated as the equivalent number of spaces.

<a name="index-_002dnip"></a>
<a name="index-_002d_002dno_002dparameter_002dindentation"></a>
<p>The indentation of type declarations in old-style function definitions
is controlled by the ‘<samp>-ip</samp>’ parameter. This is a numeric parameter
specifying how many spaces to indent type declarations. For example,
the default ‘<samp><span class="nolinebreak">-ip5</span></samp>’ makes definitions look like this:
</p>
<div class="example">
<pre class="example">char *
create_world (x, y, scale)
int x;
int y;
float scale;
{
. . .
}
</pre></div>
<p>For compatibility with other versions of indent, the option ‘<samp>-nip</samp>’
is provided, which is equivalent to ‘<samp>-ip0</samp>’.

<a name="index-_002dnlps"></a>
<a name="index-_002d_002dremove_002dpreprocessor_002dspace"></a>
<p>ANSI C allows white space to be placed on preprocessor command lines
between the character ‘<samp>#</samp>’ and the command name. By default,
<code>indent</code> removes this space, but specifying the ‘<samp>-lps</samp>’ option
directs <code>indent</code> to leave this space unmodified. The option ‘<samp>-ppi</samp>’
overrides ‘<samp>-nlps</samp>’ and ‘<samp>-lps</samp>’.
</p>
<a name="index-_002dppin"></a>
<a name="index-_002d_002dpreprocessor_002dindentationn"></a>
<p>This option can be used to request that preprocessor conditional statements can
be indented by to given number of spaces, for example with the option ‘<samp>-ppi 3</samp>’
</p>
<div class="example">
<pre class="example">#if X
#if Y
#define Z 1
#else
#define Z 0
#endif
#endif
</pre></div>
<p>becomes
</p><div class="example">
<pre class="example">#if X
# if Y
# define Z 1
# else
# define Z 0
# endif
#endif
</pre></div>
<a name="index-_002diln"></a>
<a name="index-_002d_002dindent_002dlabeln"></a>
<p>This option sets the offset at which a label (except case labels)
will be positioned. If it is set to zero or a positive number, this indicates how
far from the left margin to indent a label. If it is set to a negative number,
this indicates how far back from the current indent level to place the label.
The default setting is -2 which matches the behaviour of earlier versions of indent.
Note that this parameter does not affect the placing of case labels; see the
‘<samp>-cli</samp>’ parameter for that. For example with the option ‘<samp>-il 1</samp>’
</p>

<h2 class="section">1.9 Breaking long lines</h2>
<a name="index-_002dln"></a>
<a name="index-_002d_002dline_002dlengthn"></a>
<p>With the option ‘<samp>-l<var>n</var></samp>’, or ‘<samp>--line-length<var>n</var></samp>’, it is
possible to specify the maximum length of a line of C code, not including
possible comments that follow it.
</p>
<p>When lines become longer than the specified line length, GNU <code>indent</code>
tries to break the line at a logical place. This is new as of version 2.1
however and not very intelligent or flexible yet.
</p>
<a name="index-_002dbbo"></a>
<a name="index-_002d_002dbreak_002dbefore_002dboolean_002doperator"></a>

<a name="index-_002dnhnl"></a>
<a name="index-_002d_002dignore_002dnewlines"></a>
<p>Currently there are two options that allow one to interfere with the
algorithm that determines where to break a line.
</p>
<p>The ‘<samp>-bbo</samp>’ option causes GNU <code>indent</code> to prefer to break
long lines before the boolean operators <code>&&</code> and <code>||</code>. The
‘<samp>-nbbo</samp>’ option causes GNU <code>indent</code> not have that
preference. For example, the default option ‘<samp>-bbo</samp>’ (together
with ‘<samp>--line-length60</samp>’ and ‘<samp>--ignore-newlines</samp>’) makes code
look like this:
</p>
<div class="example">
<pre class="example"> if (mask
&& ((mask[0] == '\0')
|| (mask[1] == '\0'
&& ((mask[0] == '0') || (mask[0] == '*')))))
</pre></div>
<p>Using the option ‘<samp>-nbbo</samp>’ will make it look like this:
</p>
<div class="example">
<pre class="example"> if (mask &&
((mask[0] == '\0') ||
(mask[1] == '\0' &&
((mask[0] == '0') || (mask[0] == '*')))))
</pre></div>
<p>The default ‘<samp>-hnl</samp>’, however, honours newlines in the input file by
giving them the highest possible priority to break lines at. For example,
when the input file looks like this:
</p>
<div class="example">
<pre class="example"> if (mask
&& ((mask[0] == '\0')
|| (mask[1] == '\0' && ((mask[0] == '0') || (mask[0] == '*')))))
</pre></div>
<p>then using the option ‘<samp>-hnl</samp>’, or ‘<samp>--honour-newlines</samp>’,
together with the previously mentioned ‘<samp>-nbbo</samp>’ and
‘<samp>--line-length60</samp>’, will cause the output not to be what is given
in the last example but instead will prefer to break at the positions
where the code was broken in the input file:
</p>
<div class="example">
<pre class="example"> if (mask
&& ((mask[0] == '\0')
|| (mask[1] == '\0' &&
((mask[0] == '0') || (mask[0] == '*')))))
</pre></div>
<p>The idea behind this option is that lines which are too long, but are already
broken up, will not be touched by GNU <code>indent</code>. Really messy code
should be run through <code>indent</code> at least once using the
‘<samp>--ignore-newlines</samp>’ option though.

<h2 class="section">1.10 Disabling Formatting</h2>
<p>Formatting of C code may be disabled for portions of a program by
embedding special <em>control comments</em> in the program. To turn off
formatting for a section of a program, place the disabling control
comment <code>/* *INDENT-OFF* */</code> on a line by itself just before that
section. Program text scanned after this control comment is output
precisely as input with no modifications until the corresponding
enabling comment is scanned on a line by itself. The disabling control
comment is <code>/* *INDENT-ON* */</code>, and any text following the comment
on the line is also output unformatted. Formatting begins again with
the input line following the enabling control comment.
</p>
<p>More precisely, <code>indent</code> does not attempt to verify the closing
delimiter (<code>*/</code>) for these C comments, and any whitespace on the
line is totally transparent.
</p>
<p>These control comments also function in their C++ formats, namely
<code>// *INDENT-OFF*</code> and <code>// *INDENT-ON*</code>.
</p>
<p>It should be noted that the internal state of <code>indent</code> remains
unchanged over the course of the unformatted section. Thus, for
example, turning off formatting in the middle of a function and
continuing it after the end of the function may lead to bizarre
results. It is therefore wise to be somewhat modular in selecting code
to be left unformatted.
</p>
<p>As a historical note, some earlier versions of <code>indent</code> produced
error messages beginning with <code>*INDENT**</code>. These versions of
<code>indent</code> were written to ignore any input text lines which began
with such error messages. I have removed this incestuous feature from
GNU <code>indent</code>.

verbose mode, <code>indent</code> reports when it splits one line of input
into two more more lines of output, and gives some size statistics at
completion.

<a name="index-_002dnpmt"></a>
<p>The ‘<samp>-pmt</samp>’ option causes <code>indent</code> to preserve the access
and modification times on the output files. Using this option
has the advantage that running indent on all source and header
files in a project won’t cause <code>make</code> to rebuild all targets.
This option is only available on Operating Systems that have the
POSIX <code>utime(2)</code> function.

<h2 class="section">1.12 Bugs</h2>
<p>Please report any bugs to <a href="mailto:bug-indent@gnu.org">bug-indent@gnu.org</a>.
</p>
<p>When <code>indent</code> is run twice on a file, with the same profile,
it should <em>never</em> change that file the second time. With the
current design of <code>indent</code>, this can not be guaranteed,
and it has not been extensively tested.
</p>
<p><code>indent</code> does not understand C. In some cases this leads to
the inability to join lines. The result is that running a file
through <code>indent</code> is <em>irreversible</em>, even if the used input
file was the result of running <code>indent</code> with a given profile
(‘<tt>.indent.pro</tt>’).
</p>
<p>While an attempt was made to get <code>indent</code> working for C++, it
will not do a good job on any C++ source except the very simplest.
</p>
<p><code>indent</code> does not look at the given ‘<samp>--line-length</samp>’ option
when writing comments to the output file. This results often in comments
being put far to the right. In order to prohibit <code>indent</code> from
joining a broken line that has a comment at the end, make sure that the
comments start on the first line of the break.
</p>
<p><code>indent</code> does not count lines and comments (see the ‘<samp>-v</samp>’
option) when <code>indent</code> is turned off with
<code>/* *INDENT-OFF* */</code>.
</p>
<p>Comments of the form <code>/*UPPERCASE*/</code> are not treated as comment but as an
identifier, causing them to be joined with the next line. This renders
comments of this type useless, unless they are embedded in the code to
begin with.
