1 MAKEINDEX

2 NAME
 makeindex - a general purpose,  formatter-independent  index
 processor

2 SYNOPSIS
 makeindex [-c] [-g] [-i] [-l] [-o ind] [-p  num]  [-q]  [-r]
 [-s sfile] [-t log] [idx0 idx1 idx2...]

2 DESCRIPTION
 The program makeindex  is  a  general  purpose  hierarchical
 index  generator;  it accepts one or more input files (often
 produced by a  text  formatter  such  as  TeX  (tex(1L))  or
 troff(1),  sorts  the  entries,  and produces an output file
 which can be formatted.  The index can have up to three lev-
 els  (0,  1,  and  2)  of subitem nesting.  The way in which
 words are flagged for indexing within the main  document  is
 specific  to the formatter used; makeindex does not automate
 the process of selecting these words.  As the  output  index
 is  hierarchical,  makeindex can be considered complimentary
 to the awk(1)-based make.index(1L)  system  of  Bentley  and
 Kernighan,  which  is  specific  to troff(1), generates non-
 hierarchical indices, and employs a much simpler syntax  for
 indicating  index  entries.   For  illustration  of use with
 troff and TeX, see the section EXAMPLES below.

 The formats of the input and output files are specified in a
 style  file; by default, input is assumed to be a .idx file,
 as generated by LaTeX.

 Unless specified explicitly, the  base  name  of  the  first
 input  file  (idx0)  is used to determine the names of other
 files.  For each input file name specified, a file  of  that
 name is sought.  If this file is not found and the file name
 has no extension, the extension .idx  is  appended.   If  no
 file with this name is found, makeindex aborts.

 For important notes on how to select index keywords, see the
 document  by Lamport cited below.  As an issue separate from
 selecting index keywords, a systematic mechanism for placing
 index  terms in a document is suggested in Index Preparation
 and Processing, a paper cited below.

2 OPTIONS
 -c        Compress intermediate blanks (ignoring leading and
           trailing  blanks and tabs).  By default, blanks in
           the index key are retained.

 -g        Employ German  word  ordering  in  the  index,  in
           accord  with  rules  set  forth  in  DIN 5007.  By
           default, makeindex  employs  a  word  ordering  in
           which  precedence  is: symbols, numbers, uppercase
           letters,  lowercase  letters.   The  sequence   in

           German   word   ordering  is:  symbols,  lowercase
           letters, uppercase  letters,  numbers.   Addition-
           ally,  this  option enables makeindex to recognize
           the German TeX-commands {"a, "o,  "u  and  "s}  as
           {ae,  oe,  ue  and  ss}  during the sorting of the
           entries.  The quote character must be redefined in
           a style file (for example, redefine quote as '+').
           If the quote character is not redefined, makeindex
           will produce an error message and abort.

 -i        Take input from stdin.  When this option is speci-
           fied and -o is not, output is written to stdout.

 -l        Letter ordering; by default, word ordering is used
           (see the ORDERING section).

 -o ind    Employ ind as the output index file.  By  default,
           the  file  name is created by appending the exten-
           sion .ind to the base name of the first input file
           (idx0).

 -p num    Set the starting page number of the  output  index
           file  to  be num (useful when the index file is to
           be formatted separately).  The argument num may be
           numerical or one of the following:

           any       The starting page  is  the  last  source
                     page number plus 1.

           odd       The starting page is the first odd  page
                     following the last source page number.

           even      The starting page is the first even page
                     following the last source page number.

           The last source  page  is  obtained  by  searching
           backward in the log file for the first instance of
           a number included within  paired  square  brackets
           ([...]).   If  a page number is missing or the log
           file is not found, no attempt will be made to  set
           the  starting  page  number.   The source log file
           name is determined by appending the extension .log
           to the base name of the first input file (idx0).

 -q        Quiet  mode;  send  no  messages  to  stderr.   By
           default,  progress  and error messages are sent to
           stderr as well as to the transcript file.

 -r        Disable implicit page range formation; page ranges
           must be created by using explicit range operators;
           see SPECIAL EFFECTS below.  By default,  three  or
           more    successive    pages    are   automatically

           abbreviated as a range (e.g. 1-5).

 -s sty    Employ sty as the style file  (no  default).   The
           environment  variable  INDEXSTYLE defines the path
           where the style file should be found.

 -t log    Employ log as the transcript  file.   By  default,
           the  file  name is created by appending the exten-
           sion .ilg to the base name of the first input file
           (idx0).

2 STYLE FILE
 The style file informs makeindex about  the  format  of  the
 .idx input files and the intended format of the final output
 file; examples appear below.  This file can reside  anywhere
 in  the path defined by the environment variable INDEXSTYLE.
 The style file contains a  list  of  <specifier,  attribute>
 pairs.  There are two types of specifiers: input and output.
 Pairs do not have to appear in any particular order.  A line
 begun by `%' is a comment.  In the following list of specif-
 iers and arguments, <string> is an arbitrary  string  delim-
 ited  by  double  quotes  ("..."), <char> is a single letter
 embraced by single quotes ('...'), and <number> is a  nonne-
 gative  integer.   The maximum length of a <string> is 2048.
 A  literal  backslash  or  quote  must  be  escaped  (by   a
 backslash).   Anything  not specified in the style file will
 be assigned a default value, which is shown at the  head  of
 the rightmost column.

3 INPUT STYLE SPECIFIERS
 actual <char>            '@'
                          Symbol  indicating  that  the  next
                          entry  is  to  appear in the output
                          file.

 arg_close <char>         '}'
                          Closing  delimiter  for  the  index
                          entry argument.

 arg_open <char>          '{'
                          Opening  delimiter  for  the  index
                          entry argument.

 encap <char>             '|'
                          Symbol indicating that the rest  of
                          the  argument list is to be used as
                          the encapsulating command  for  the
                          page number.

 escape <char>            '\\'
                          Symbol which escapes the  following
                          letter, unless its preceding letter

                          is escape.  Note: quote is used  to
                          escape the letter which immediately
                          follows it, but if it  is  preceded
                          by escape, it is treated as a ordi-
                          nary character.  These two  symbols
                          must be distinct.

 keyword <string>         "\\indexentry"
                          Command which tells makeindex  that
                          its argument is an index entry.

 level <char>             '!'
                          Delimiter denoting a new  level  of
                          subitem.

 quote <char>             '"'
                          Note: quote is used to  escape  the
                          letter  which  immediately  follows
                          it,  but  if  it  is  preceded   by
                          escape, it is treated as a ordinary
                          character.  These two symbols  must
                          be distinct.

 range_close <char>       ')'
                          Closing  delimiter  indicating  the
                          end of an explicit page range.

 range_open <char>        '('
                          Opening  delimiter  indicating  the
                          beginning   of   an  explicit  page
                          range.

                          when before a new  group  (symbols,
                          numbers, and the 26 letters): posi-

                          letter  to be inserted between pre-
                          fix and suffix, and negative values
                          cause  a  lowercase  letter  to  be
                          inserted (default is 0, which  pro-

2 EXAMPLES
3 TeX EXAMPLE
 The following example shows a style  file  called  book.ist,
 which  defines  an  index  for a book which can be formatted
 independently of the main source:

      preamble
      "\\documentstyle[12pt]{book}
      \\begin{document}
      \\begin{theindex}
      {\\small\n"
      postamble
      "\n\n}
      \\end{theindex}
      \\end{document}\n"

 Assuming that a particular book style requires the index (as
 well  as any chapters) to start from an odd page number, and
 that the input file is named foo.idx, the following  command
 line produces output in file footmp.ind:

      makeindex  -s book.ist  -o footmp.ind  -p odd  foo

 Here a  non-default  output  file  name  is  used  to  avoid
 clobbering  the  output  for  the  book  itself  (presumably
 foo.dvi, which would have been  the  default  name  for  the
 index output file!).

3 TROFF EXAMPLE
 A sample control file for creating an index, which  we  will
 assume resides in the file sample.ist:

      keyword "IX:"
      preamble
      ".\\\" start of index output
      \".\\\" enter two column mode
      .2C
      .SH
      .ce
      INDEX
      .XS
      INDEX
      .XE
      .R
      .ps 9p
      .vs 11p
      .sp
      .de I1
      .ti 0.25i
      ..
      .de I2
      .ti 0.5i
      .."
      postamble "\n.\\\" end of index output"
      setpage_prefix "\n.nr % "
      setpage_suffix ""
      group_skip "\n.sp 1.0"

      item_2 "\n.I2\n"
      item_01 "\n.I1\n"
      item_x1 "\n.I1\n"
      item_12 "\n.I2\n"
      item_x2 "\n.I2\n"
      delim_0 ", "
      delim_1 ", "
      delim_2 ", "
      delim_r "-"
      delim_t "."
      encap_prefix "\\fB"
      encap_infix ""
      encap_suffix "\\fP"
      indent_space ""
      indent_length 0

 The local macro package may require modification, as in this
 example of an extension to the -ms macros (note that at some

 sites, this macro should replace a pre-existing macro of the
 same name):

      .
      .de IX
      .ie '\\n(.z'' .tm IX: \\$1 \\$2 \\$3 \\$4 \\$5 \\$6 \\$7 \\$8 \\$9 {\\n(PN}
      .el \\!.IX \\$1 \\$2 \\$3 \\$4 \\$5 \\$6 \\$7 \\$8 \\$9 {\\n(PN}
      ..

 (note that the string {\\n(PN} is separated from the rest of
 the  line  by  a  tab.  If your local macro package does not
 contain this extension, just  include  those  lines  at  the
 beginning  of  your  file.   Here is a simple troff(1) input
 file, which we will assume is named sample.txt:

      This is a sample file to test the \fImakeindex\fP(1L)
      program, and see
      .IX {indexing!programs!C language}
      .IX {makeindex@\fImakeindex\fP(1L)}
      .bp
      .rs
      .IX {Knuth}
      .IX {typesetting!computer-aided}
      how well it functions in the \fItroff\fP(1) environment.

 Note that index entries are  indicated  by  the  .IX  macro,
 which  causes  the  following  text  to be written to stdout
 along with the current page number.

3 CREATING THE INDEX FILE IN THE BOURNE SHELL
 To create an input file for makeindex, in the  Bourne  shell
 environment, do the equivalent at your site of the command:

 psroff -ms -Tpsc -t sample.txt > /dev/null 2> sample.tmp

 Some sites will  require  ditroff  instead  of  psroff.   To
 filter out any genuine error messages, invoke grep(1):

      grep '^IX: ' sample.tmp > sample.idx

3 CREATING THE INDEX FILE USING UCSF ENHANCED TROFF/TRANSCRIPT

 With  UCSF  Enhanced  troff/TRANSCRIPT,  the  -I  option  of
 psroff(1L)  can  produce  both formatter output and an index
 file:

      psroff -ms -I sample.inp -Tpsc sample.txt

 If it is wished to suppress the formatter output:

      psroff -ms -I sample.inp -Tpsc -t sample.txt > /dev/null

3 COMPLETING THE INDEX
 Any of the above procedures leaves the input  for  makeindex
 in sample.inp.  The next step is to invoke makeindex:

      makeindex -s sample.ist sample.idx

 This leaves troff(1)-ready output in the file sample.ind.

2 ORDERING
 By default, makeindex  assumes  word  ordering;  if  the  -l
 option  is in effect, letter ordering is used.  In word ord-
 ering, a blank precedes any letter in the alphabet,  whereas
 in  letter  ordering,  it  does  not  count at all.  This is
 illustrated by the following example:

      word order                      letter order
      sea lion                        seal
      seal                            sea lion

 Numbers are always sorted in numeric order.  For instance,

      9 (nine),  123
      10 (ten), see Derek, Bo

 Letters are first sorted without regard to case; when  words
 are  identical, the uppercase version precedes its lowercase
 counterpart.

 A special symbol is defined here to  be  any  character  not
 appearing  in the union of digits and the English alphabetic
 characters.  Patterns starting with special symbols  precede
 numbers, which precede patterns starting with letters.  As a
 special case, a string starting with a digit but mixed  with
 non-digits  is  considered  to  be a pattern starting with a
 special character.

2 SPECIAL EFFECTS
 Entries such as

      \indexentry{alpha}{1}
      \indexentry{alpha!beta}{3}
      \indexentry{alpha!beta!gamma}{10}

 in the input file will be converted to

      \item alpha, 1
         \subitem beta, 3
            \subsubitem gamma, 10

 in the output index file.   Notice  that  the  level  symbol
 (`!') is used above to delimit hierarchical levels.

 It is possible to make an item appear in a  designated  form
 by using the actual (`@') operator.  For instance,

      \indexentry{alpha@{\it alpha\/}}{1}

 will become

      \item {\it alpha\/},  1

 after processing.  The pattern preceding `@' is used as sort
 key,  whereas  the one following it is written to the output
 file.  Note that two appearances of the same key,  one  with
 and  one  without  the actual operator, are regarded as dis-
 tinct entries.

 The item, subitem, and subsubitem fields may have individual
 sort keys:

      \indexentry{aa@{\it aa\/}!bb@{\it bb\/}!cc@{\it cc\/}}{1}

 This will be converted to

      \item {\it aa}, 1
         \subitem {\it bb}, 3
            \subsubitem {\it cc}, 10

 It is possible to encapsulate a page number  with  a  desig-
 nated command using the encap (`|') operator:

      \indexentry{alpha|bold}{1}

 will be converted to

      \item alpha, \bold{1}

 where, with a suitable definition  for  TeX,  \bold{n}  will
 expand to {\bf n}.  In this example, the three output attri-
 butes  associated  with  page  encapsulation   encap_prefix,
 encap_infix, and encap_suffix, correspond to backslash, left
 brace, and right brace, respectively.  This mechanism allows
 page numbers to be set in different fonts.  For example, the
 page where the definition of a keyword appears can be in one
 font,  the  location  of a primary example can be in another
 font, and other appearances in yet a third font.

 The encap operator can also be used to create  cross  refer-
 ences in the index:

      \indexentry{alpha|see{beta}}{1}

 will become

      \item alpha, \see{beta}{1}

 in the output file, where

      \see{beta}{1}

 will expand to

      {\it see\/} beta

 Note that in a cross reference like  this  the  page  number
 disappears.

 A pair of encap  concatenated  with  range_open  (`|(')  and
 range_close (`|)') creates an explicit page range:

      \indexentry{alpha|(}{1}
      \indexentry{alpha|)}{5}

 will become

      \item alpha, 1-5

 Intermediate pages indexed by the same key  will  be  merged
 into  the  range implicitly.  This is especially useful when
 an entire section  about  a  particular  subject  is  to  be
 indexed,  in  which  case only the range opening and closing
 operators need to be inserted at the beginning  and  end  of
 the section.  Explicit page range formation can also include
 an extra command to set the page range in a designated font:

      \indexentry{alpha|(bold}{1}
      \indexentry{alpha|)}{5}

 will become

      \item alpha, \bold{1--5}

 Several potential problems  are  worth  mentioning.   First,
 entries like

      \indexentry{alpha|(}{1}
      \indexentry{alpha|bold}{3}
      \indexentry{alpha|)}{5}

 will be interpreted as

      \item alpha, \bold{3}, 1--5

 but  with  a  warning  message  in  the   transcript   about
 encountering an inconsistent page encapsulator.  An explicit
 range beginning in a Roman page number and ending in  Arabic

 is  also  considered an error.  In this instance, (if possi-
 ble) the range is broken into two subranges,  one  in  Roman
 and the other in Arabic.  For instance,

      \indexentry{alpha|(}{i}
      \indexentry{alpha}{iv}
      \indexentry{alpha}{3}
      \indexentry{alpha|)}{7}

 will be turned into

      \item alpha, i--iv, 3--7

 with a warning message in the  transcript  file  complaining
 about an illegal range formation.

 Finally, every special symbol mentioned in this section  may
 be escaped by the quote operator (`"').  Thus

      \indexentry{alpha"@beta}{1}

 will actually become

      \item alpha@beta,  1

 as a result of executing makeindex.  The  quoting  power  of
 quote  is eliminated if it is immediately preceded by escape
 (`\').  For example,

      \indexentry{f\"ur}{1}

 becomes

      \item f\"ur, 1

 which represents an umlaut-accented `u' to the TeX family of
 processors.

 From version 2.11 of makeindex, the quote operator may quote
 any  character  in  the  range  1  ... 255.   Character 0 is
 excluded because it is  used  internally  in  the  makeindex
 source  code as a string terminator.  With this change, sort
 keys can be created for all eight-bit characters  except  0.
 The sorting order is

      punctuation characters (in ASCII order),
      digits,
      control characters (1 ... 31),
      space (32),
      letters (ignoring case),
      characters 127 ... 255.

 Here is an example showing the  indexing  of  all  printable
 ASCII characters other than letters and digits, assuming the
 default TeX format.  For convenience, the page number refer-
 ences are the corresponding ASCII ordinal values.

      \indexentry{" @"  (space)}{32}
      \indexentry{"!@"! (exclamation point)}{33}
      \indexentry{""@"" (quotation mark)}{34}
      \indexentry{"#@"\# (sharp sign)}{35}
      \indexentry{"$@"\$ (dollar sign)}{36}
      \indexentry{"%@"\% (percent sign)}{37}
      \indexentry{"&@"\& (ampersand)}{38}
      \indexentry{"<@"$<$ (left angle bracket)}{60}
      \indexentry{"=@"= (equals)}{61}
      \indexentry{">@"$>$ (right angle bracket)}{62}
      \indexentry{"?@"? (query)}{63}
      \indexentry{"@@"@ (at sign)}{64}
      \indexentry{"[@"[ (left square bracket)}{91}
      \indexentry{"\@"\verb=\= (backslash)}{92}
      \indexentry{"]@"] (right square bracket)}{93}
      \indexentry{"^@"\verb=^= (caret)}{94}
      \indexentry{"_@"\verb=_= (underscore)}{95}
      \indexentry{"`@"\verb=~= (grave accent)}{96}
      \indexentry{"{@"\"{ (left brace)}{123}
      \indexentry{"|@"\verb="|= (vertical bar)}{124}
      \indexentry{"}@"\"} (right brace)}{125}
      \indexentry{"~@"\verb=~= (tilde)}{126}

 Characters in the actual fields following the `@'  character
 which  have  special significance to TeX must be represented
 as control sequences, or as math mode characters.  Note par-
 ticularly  how  the  entries for the at sign, left and right
 braces, and the vertical bar, are  coded.   The  index  file
 output by makeindex for this example looks like this:

      \begin{theindex}

        \item ! (exclamation point), 33
        \item " (quotation mark), 34
        \item \# (sharp sign), 35
        \item \$ (dollar sign), 36
        \item \% (percent sign), 37
        \item \& (ampersand), 38
        \item $<$ (left angle bracket), 60
        \item = (equals), 61
        \item $>$ (right angle bracket), 62
        \item ? (query), 63
        \item @ (at sign), 64
        \item [ (left square bracket), 91
        \item \verb=\= (backslash), 92
        \item ] (right square bracket), 93
        \item \verb=^= (caret), 94

        \item \verb=_= (underscore), 95
        \item \verb=~= (grave accent), 96
        \item \{ (left brace), 123
        \item \verb=|= (vertical bar), 124
        \item \} (right brace), 125
        \item \verb=~= (tilde), 126

        \indexspace

        \item   (space), 32

      \end{theindex}
