+This is the C indenter, it originally came from the University of Illinois
+via some distribution tape for PDP-11 Unix. It has subsequently been
+hacked upon by James Gosling @ CMU. It isn't very pretty, and really needs
+to be completely redone, but it is probably the nicest C pretty printer
+around.
+
+Further additions to provide "Kernel Normal Form" were contributed
+by the folks at Sun Microsystems.

+> Subject: Re: Indent...
+
+Thank you for your response about indent. I was wrong in my original
+observation (or mis-observation :-). UCB did keep the Illinois
+copyright intact.
+
+The issue still is whether we can distribute indent, and if we can, which
+version. David Willcox (the author) states that:
+
+| Several people have asked me on what basis I claim that indent is in
+| the public domain. I knew I would be sorry I made that posting.
+|
+| Some history. Way back in 1976, the project I worked on at the
+| University of Illinois Center for Advanced Computation had a huge
+| battle about how to format C code. After about a week of fighting, I
+| got disgusted and wrote a program, which I called indent, to reformat C
+| code. It had a bunch of different options that would let you format
+| the output the way you liked. In particular, all of the different
+| formats being championed were supported.
+|
+| It was my first big C program. It was ugly. It wasn't designed, it
+| just sort of grew. But it pretty much worked, and it stopped most of
+| the fighting.
+|
+| As a matter of form, I included a University of Illinois Copyright
+| notice. However, my understanding was that, since the work was done
+| on an ARPA contract, it was in the public domain.
+|
+| Time passed. Some years later, indent showed up on one of the early
+| emacs distributions.
+|
+| Later still, someone from UC Berkeley called the UofI and asked if
+| indent was in the public domain. They wanted to include it in their
+| UNIX distributions, along with the emacs stuff. I was no longer at the
+| UofI, but Rob Kolstad, who was, asked me about it. I told him I didn't
+| care if they used it, and since then it has been on the BSD distributions.
+|
+| Somewhere along the way, several other unnamed people have had their
+| hands in it. It was converted to understand version 7 C. (The
+| original was version 6.) It was converted from its original filter
+| interface to its current "blow away the user's file" interface.
+| The $HOME/.indent.pro file parsing was added. Some more formatting
+| options were added.
+|
+| The source I have right now has two copyright notices. One is the
+| original from the UofI. One is from Berkeley.
+|
+| I am not a lawyer, and I certainly do not understand copyright law. As
+| far as I am concerned, the bulk of this program, everything covered by
+| the UofI copyright, is in the public domain, and worth every penny.
+| Berkeley's copyright probably should only cover their changes, and I
+| don't know their feelings about sending it out.
+
+In any case, there appears to be none at UofI to clarify/and change
+that copyright, but I am confident (based on the statements of its
+author) that the code, as it stands with its copyright, is
+distributable, and will not cause any legal problems.
+
+Hence, the issue reduces to *which* one to distribute through
+comp.sources.unix. I would suggest that with the permission of you
+folks (given that you have parts copyrighted), we distribute the 4.3
+version of indent, which appears to be the most up-to-date version. I
+happen to have just about every known version of indent, including the
+very original submission from the author to a unix tape, later the
+G-Emacs version, any 4.n version, sun version and the Unipress
+version. I still think we should not have to "go-back-in-time" and
+re-do all the work you people have done.
+
+I hope to hear from you as to what you think about this. You may of
+course send 4.3 version to the moderator directly, or you can let me
+know of your permission, and I will send the sources, or you can let
+me know that 4.3 version is off-limits, in which case we would probably
+have to revert to an older version. One way or another, I hope to get
+a version of indent to comp.sources.unix.
+
+regards.. oz

+pg_bsd_indent
+
+This is a lightly modified version of the "indent" program maintained
+by the FreeBSD project. The modifications are mostly to make it portable
+to non-BSD-ish platforms, though we do have one formatting switch we
+couldn't convince upstream to take.
+
+To build it, you will need a Postgres installation, version 9.5 or newer.
+(Once built, the program doesn't depend on that installation.)
+
+To build, just say "make"; or if pg_config from your Postgres installation
+isn't in your PATH, say
+ make PG_CONFIG=path/to/pg_config
+Optionally, run "make test" for some simple sanity checks.
+
+To install, copy pg_bsd_indent to somewhere in your usual PATH.
+(If you say "make install", it will try to put it in your Postgres
+installation directory, which is most likely not what you want for
+long-term use.)
+
+TODO: add build support and instructions for Windows
+
+
+If you happen to be hacking upon the indent source code, the closest
+approximation to the existing indentation style seems to be
+
+ ./pg_bsd_indent -i4 -l79 -di12 -nfc1 -nlp -sac somefile.c
+
+although this has by no means been rigorously adhered to.
+(What was that saw about the shoemaker's children?)

+.Sh DESCRIPTION
+The
+.Nm
+utility is a
+.Em C
+program formatter.
+It reformats the
+.Em C
+program in the
+.Ar input-file
+according to the switches.
+The switches which can be
+specified are described below.
+They may appear before or after the file
+names.
+.Pp
+.Sy NOTE :
+If you only specify an
+.Ar input-file ,
+the formatting is
+done `in-place', that is, the formatted file is written back into
+.Ar input-file
+and a backup copy of
+.Ar input-file
+is written in the current directory.
+If
+.Ar input-file
+is named
+.Sq Pa /blah/blah/file ,
+the backup file is named
+.Sq Pa file.BAK .
+.Pp
+If
+.Ar output-file
+is specified,
+.Nm
+checks to make sure that it is different from
+.Ar input-file .
+.Pp
+The options listed below control the formatting style imposed by
+.Nm .
+.Bl -tag -width Op
+.It Fl bacc , nbacc
+If
+.Fl bacc
+is specified, a blank line is forced around every conditional
+compilation block.
+For example, in front of every #ifdef and after every #endif.
+Other blank lines surrounding such blocks will be swallowed.
+Default:
+.Fl nbacc .
+.It Fl bad , nbad
+If
+.Fl bad
+is specified, a blank line is forced after every block of
+declarations.
+Default:
+.Fl nbad .
+.It Fl badp , nbadp
+This is vaguely similar to
+.Fl bad
+except that it only applies to the first set of declarations
+in a procedure (just after the first `{') and it causes a blank
+line to be generated even if there are no declarations.
+The default is
+.Fl nbadp.
+.It Fl bap , nbap
+If
+.Fl bap
+is specified, a blank line is forced after every procedure body.
+Default:
+.Fl nbap .
+.It Fl bbb , nbbb
+If
+.Fl bbb
+is specified, a blank line is forced before every block comment.
+Default:
+.Fl nbbb .
+.It Fl \&bc , nbc
+If
+.Fl \&bc
+is specified, then a newline is forced after each comma in a declaration.
+.Fl nbc
+turns off this option.
+Default:
+.Fl \&nbc .
+.It Fl \&bl , \&br
+Specifying
+.Fl \&bl
+lines up compound statements like this:
+.Bd -literal -offset indent
+if (...)
+{
+ code
+}
+.Ed
+.Pp
+Specifying
+.Fl \&br
+(the default) makes them look like this:
+.Bd -literal -offset indent
+if (...) {
+ code
+}
+.Ed
+.It Fl bs , nbs
+Whether a blank should always be inserted after sizeof.
+The default is
+.Fl nbs.
+.It Fl c Ns Ar n
+The column in which comments on code start.
+The default is 33.
+.It Fl cp Ns Ar n
+The column in which comments on #else and #endif start.
+The default is 0, which effectively separates the directives from comments by
+a single space.
+.It Fl cd Ns Ar n
+The column in which comments on declarations start.
+The default
+is for these comments to start in the same column as those on code.
+.It Fl cdb , ncdb
+Enables (disables) the placement of comment delimiters on blank lines.
+With
+this option enabled, comments look like this:
+.Bd -literal -offset indent
+ /*
+ * this is a comment
+ */
+.Ed
+.Pp
+Rather than like this:
+.Bd -literal -offset indent
+ /* this is a comment */
+.Ed
+.Pp
+This only affects block comments, not comments to the right of
+code.
+The default is
+.Fl cdb .
+.It Fl ce , nce
+Enables (disables) forcing of `else's to cuddle up to the immediately preceding
+`}'.
+The default is
+.Fl \&ce .
+.It Fl \&ci Ns Ar n
+Sets the continuation indent to be
+.Ar n .
+Continuation
+lines will be indented that far from the beginning of the first line of the
+statement.
+Parenthesized expressions have extra indentation added to
+indicate the nesting, unless
+.Fl \&lp
+is in effect
+or the continuation indent is exactly half of the main indent.
+.Fl \&ci
+defaults to the same value as
+.Fl i .
+.It Fl cli Ns Ar n
+Causes case labels to be indented
+.Ar n
+tab stops to the right of the containing
+.Ic switch
+statement.
+.Fl cli0.5
+causes case labels to be indented half a tab stop.
+The
+default is
+.Fl cli0 .
+.It Fl d Ns Ar n
+Controls the placement of comments which are not to the
+right of code.
+For example,
+.Fl \&d\&1
+means that such comments are placed one indentation level to the
+left of code.
+Specifying the default
+.Fl \&d\&0
+lines up these comments with the code.
+See the section on comment
+indentation below.
+.It Fl \&di Ns Ar n
+Specifies the indentation, in character positions,
+of global variable names and all struct/union member names
+relative to the beginning of their type declaration.
+The default is
+.Fl di16 .
+.It Fl dj , ndj
+.Fl \&dj
+left justifies declarations.
+.Fl ndj
+indents declarations the same as code.
+The default is
+.Fl ndj .
+.It Fl \&ei , nei
+Enables (disables) special
+.Ic else-if
+processing.
+If it is enabled, an
+.Ic if
+following an
+.Ic else
+will have the same indentation as the preceding
+.Ic \&if
+statement.
+The default is
+.Fl ei .
+.It Fl eei , neei
+Enables (disables) extra indentation on continuation lines of
+the expression part of
+.Ic if
+and
+.Ic while
+statements.
+These continuation lines will be indented one extra level.
+The default is
+.Fl neei .
+.It Fl fbs , nfbs
+Enables (disables) splitting the function declaration and opening brace
+across two lines.
+The default is
+.Fl fbs .
+.It Fl fc1 , nfc1
+Enables (disables) the formatting of comments that start in column 1.
+Often, comments whose leading `/' is in column 1 have been carefully
+hand formatted by the programmer.
+In such cases,
+.Fl nfc1
+should be
+used.
+The default is
+.Fl fc1 .
+.It Fl fcb , nfcb
+Enables (disables) the formatting of block comments (ones that begin
+with `/*\\n').
+Often, block comments have been not so carefully hand formatted by the
+programmer, but reformatting that would just change the line breaks is not
+wanted.
+In such cases,
+.Fl nfcb
+should be used.
+Block comments are then handled like box comments.
+The default is
+.Fl fcb .
+.It Fl i Ns Ar n
+The number of columns for one indentation level.
+The default is 8.
+.It Fl \&ip , nip
+Enables (disables) the indentation of parameter declarations from the left
+margin.
+The default is
+.Fl \&ip .
+.It Fl l Ns Ar n
+Maximum length of an output line.
+The default is 78.
+.It Fl lc Ns Ar n
+Maximum length of an output line in a block comment.
+The default is 0, which means to limit block comment lines in accordance with
+.Fl l.
+.It Fl \&ldi Ns Ar n
+Specifies the indentation, in character positions,
+of local variable names
+relative to the beginning of their type declaration.
+The default is for local variable names to be indented
+by the same amount as global ones.
+.It Fl \&lp , nlp
+Lines up code surrounded by parentheses in continuation lines.
+With
+.Fl \&lp ,
+if a line
+has a left paren which is not closed on that line, then continuation lines
+will be lined up to start at the character position just after the left
+paren.
+For example, here is how a piece of continued code looks with
+.Fl nlp
+in effect:
+.Bd -literal -offset indent
+p1 = first_procedure(second_procedure(p2, p3),
+\ \ third_procedure(p4, p5));
+.Ed
+.Pp
+With
+.Fl lp
+in effect (the default) the code looks somewhat clearer:
+.Bd -literal -offset indent
+p1\ =\ first_procedure(second_procedure(p2,\ p3),
+\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ third_procedure(p4,\ p5));
+.Ed
+.Pp
+Inserting two more newlines we get:
+.Bd -literal -offset indent
+p1\ =\ first_procedure(second_procedure(p2,
+\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ p3),
+\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ third_procedure(p4,
+\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ p5));
+.Ed
+.It Fl \&lpl , nlpl
+With
+.Fl \&lpl ,
+code surrounded by parentheses in continuation lines is lined up even if it
+would extend past the right margin.
+With
+.Fl \&nlpl
+(the default), such a line that would extend past the right margin is moved
+left to keep it within the margin, if that does not require placing it to
+the left of the prevailing indentation level.
+These switches have no effect if
+.Fl nlp
+is selected.
+.It Fl npro
+Causes the profile files,
+.Sq Pa ./.indent.pro
+and
+.Sq Pa ~/.indent.pro ,
+to be ignored.
+.It Fl P Ns Ar file
+Read profile from
+.Ar file .
+.It Fl pcs , npcs
+If true
+.Pq Fl pcs
+all procedure calls will have a space inserted between
+the name and the `('.
+The default is
+.Fl npcs .
+.It Fl psl , npsl
+If true
+.Pq Fl psl
+the names of procedures being defined are placed in
+column 1 \- their types, if any, will be left on the previous lines.
+The
+default is
+.Fl psl .
+.It Fl sac , nsac
+Control whether parenthesized type names in casts are followed by a space or
+not.
+The default is
+.Fl nsac .
+.It Fl \&sc , nsc
+Enables (disables) the placement of asterisks (`*'s) at the left edge of all
+comments.
+The default is
+.Fl sc .
+.It Fl sob , nsob
+If
+.Fl sob
+is specified, indent will swallow optional blank lines.
+You can use this to
+get rid of blank lines after declarations.
+Default:
+.Fl nsob .
+.It Fl \&st
+Causes
+.Nm
+to take its input from stdin and put its output to stdout.
+.It Fl ta
+Automatically add all identifiers ending in "_t" to the list
+of type keywords.
+.It Fl T Ns Ar typename
+Adds
+.Ar typename
+to the list of type keywords.
+Names accumulate:
+.Fl T
+can be specified more than once.
+You need to specify all the typenames that
+appear in your program that are defined by
+.Ic typedef
+\- nothing will be
+harmed if you miss a few, but the program will not be formatted 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:
+.Ic typedef
+causes a syntactic change in the
+language and
+.Nm
+cannot find all
+instances of
+.Ic typedef .
+.It Fl tpg , ntpg
+If
+.Fl tpg
+is specified, follow Postgres rules about when to use spaces versus
+tabs for indentation, that is, use a space instead of a tab if the
+tab would move only one column and no tab will follow it.
+Default:
+.Fl ntpg .
+.It Fl ts Ns Ar n
+Assumed distance between tab stops.
+The default is 8.
+.It Fl U Ns Ar file
+Adds type names from
+.Ar file
+to the list of type keywords.
+.It Fl ut , nut
+Enables (disables) the use of tab characters in the output.
+The default is
+.Fl ut .
+.It Fl v , \&nv
+.Fl v
+turns on `verbose' mode;
+.Fl \&nv
+turns it off.
+When in verbose mode,
+.Nm
+reports when it splits one line of input into two or more lines of output,
+and gives some size statistics at completion.
+The default is
+.Fl \&nv .
+.It Fl -version
+Causes
+.Nm
+to print its version number and exit.
+.El
+.Pp
+You may set up your own `profile' of defaults to
+.Nm
+by creating a file called
+.Pa .indent.pro
+in your login directory and/or the current directory and including
+whatever switches you like.
+A `.indent.pro' in the current directory takes
+precedence over the one in your login directory.
+If
+.Nm
+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 spaces, tabs or newlines.
+.Pp
+.Ss Comments
+.Sq Em Box
+.Em comments .
+The
+.Nm
+utility
+assumes that any comment with a dash or star immediately after the start of
+comment (that is, `/*\-' or `/**') is a comment surrounded by a box of stars.
+Each line of such a comment is left unchanged, except that its indentation
+may be adjusted to account for the change in indentation of the first line
+of the comment.
+.Pp
+.Em Straight text .
+All other comments are treated as straight text.
+The
+.Nm
+utility fits as many words (separated by blanks, tabs, or newlines) on a
+line as possible.
+Blank lines break paragraphs.
+.Ss Comment indentation
+If a comment is on a line with code it is started in the `comment column',
+which is set by the
+.Fl c Ns Ns Ar n
+command line parameter.
+Otherwise, the comment is started at
+.Ar n
+indentation levels less than where code is currently being placed, where
+.Ar n
+is specified by the
+.Fl d Ns Ns Ar n
+command line parameter.
+If the code on a line extends past the comment
+column, the comment starts further to the right, and the right margin may be
+automatically extended in extreme cases.
+.Ss Preprocessor lines
+In general,
+.Nm
+leaves preprocessor lines alone.
+The only
+reformatting that it will do is to straighten up trailing comments.
+It
+leaves embedded comments alone.
+Conditional compilation
+.Pq Ic #ifdef...#endif
+is recognized and
+.Nm
+attempts to correctly
+compensate for the syntactic peculiarities introduced.
+.Ss C syntax
+The
+.Nm
+utility 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 malformed syntax.
+In particular, the use of macros like:
+.Pp
+.Dl #define forever for(;;)
+.Pp
+is handled properly.
+.Sh ENVIRONMENT
+The
+.Nm
+utility uses the
+.Ev HOME
+environment variable.
+.Sh FILES
+.Bl -tag -width "./.indent.pro" -compact
+.It Pa ./.indent.pro
+profile file
+.It Pa ~/.indent.pro
+profile file
+.El
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .
+.Sh BUGS
+The
+.Nm
+utility has even more switches than
+.Xr ls 1 .
+.Pp
+A common mistake is to try to indent all the
+.Em C
+programs in a directory by typing:
+.Pp
+.Dl indent *.c
+.Pp
+This is probably a bug, not a feature.
