       groff_ms - groff ms macros

SYNOPSIS         top

       groff -ms [ options... ] [ files... ]
       groff -m ms [ options... ] [ files... ]

DESCRIPTION         top

       This manual page describes the GNU version of the ms macros, part of
       the groff typesetting system.  The ms macros are mostly compatible
       with the documented behavior of the 4.3 BSD Unix ms macros (see
       Differences from troff ms below for details).  The ms macros are
       suitable for reports, letters, books, and technical documentation.

USAGE         top

       The ms macro package expects files to have a certain amount of
       structure.  The simplest documents can begin with a paragraph macro
       and consist of text separated by paragraph macros or even blank
       lines.  Longer documents have a structure as follows:

       Document type
              If you use the RP (report) macro at the beginning of the
              document, groff prints the cover page information on its own
              page; otherwise it prints the information on the first page
              with your document text immediately following.  Other document
              formats found in AT&T troff are specific to AT&T or Berkeley,
              and are not supported in groff ms.

       Format and layout
              By setting number registers, you can change your document's
              type (font and size), margins, spacing, headers and footers,
              and footnotes.  See Document control registers below for more

       Cover page
              A cover page consists of a title, and optionally the author's
              name and institution, an abstract, and the date.  See Cover
              page macros below for more details.

       Body   Following the cover page is your document.  It consists of
              paragraphs, headings, and lists.

       Table of contents
              Longer documents usually include a table of contents, which
              you can add by placing the TC macro at the end of your

   Document control registers
       The following table lists the document control number registers.  For
       the sake of consistency, set registers related to margins at the
       beginning of your document, or just after the RP macro.

   Cover page macros
       Use the following macros to create a cover page for your document  in
       the order shown.

       .RP [no]
              Specifies  the  report  format  for your document.  The report
              format creates a separate cover page.  With no RP macro, groff
              prints a subset of the cover page on page 1 of your document.

              If you use the optional no argument, groff prints a title page
              but does not repeat any of the title page information  (title,
              author, abstract, etc.) on page 1 of the document.

       .P1    (P-one)  Prints  the  header  on  page  1.   The default is to
              suppress the header.

       .DA [xxx]
              (optional) Print the current date, or  the  arguments  to  the
              macro  if  any,  on  the  title page (if specified) and in the
              footers.  This is the default for nroff.

       .ND [xxx]
              (optional) Print the current date, or  the  arguments  to  the
              macro  if any, on the title page (if specified) but not in the
              footers.  This is the default for troff.

       .TL    Specifies the document title.  Groff collects  text  following
              the TL macro into the title, until reaching the author name or

       .AU    Specifies the author's name.  You can specify multiple authors
              by using an AU macro for each author.

       .AI    Specifies  the author's institution.  You can specify multiple

       .AB [no]
              Begins the  abstract.   The  default  is  to  print  the  word
              ABSTRACT,  centered  and  in  italics,  above  the text of the
              abstract.  The option no suppresses this heading.

       .AE    End the abstract.

       Use the PP macro to create indented paragraphs, and the LP  macro  to
       create paragraphs with no initial indent.

       The  QP  macro  indents all text at both left and right margins.  The
       effect is identical to the HTML <BLOCKQUOTE> The  next  paragraph  or
       heading returns margins to normal.

       The  XP  macro produces an exdented paragraph.  The first line of the
       paragraph begins  at  the  left  margin,  and  subsequent  lines  are
       indented (the opposite of PP).

       For  each  of  the above paragraph types, and also for any list entry
       introduced by the IP macro (described later),  the  document  control
       register  PORPHANS,  sets  the  minimum number of lines which must be
       printed, after the start of the paragraph, and before any page  break
       occurs.  If there is insufficient space remaining on the current page
       to accommodate this number of lines, then  a  page  break  is  forced
       before the first line of the paragraph is printed.

       Similarly,  when  a  section  heading (see subsection Headings below)
       precedes any of these paragraph types, the HORPHANS document  control
       register specifies the minimum number of lines of the paragraph which
       must be kept on the same page as the heading.  If insufficient  space
       remains  on  the  current  page  to  accommodate the heading and this
       number of lines of paragraph text, then a page break is forced before
       the heading is printed.

       Use  headings  to  create a hierarchical structure for your document.
       By default, the ms macros print headings in bold using the same  font
       family  and  point  size  as the body text.  For output devices which
       support scalable fonts, this behaviour may be modified,  by  defining
       the document control registers, GROWPS and PSINCR.

       The following heading macros are available:

       .NH xx Numbered  heading.   The  argument  xx  is  either  a  numeric
              argument  to  indicate  the   level   of   the   heading,   or
              S xx xx "..."   to  set the section number explicitly.  If you
              specify heading levels out of sequence, such as invoking .NH 3
              after .NH 1, groff prints a warning on standard error.

              If  the  GROWPS  register  is  set to a value greater than the
              level of the heading, then the point size of the heading  will
              be  increased  by PSINCR units over the text size specified by
              the PS register, for each level by which the heading level  is
              less than the value of GROWPS.  For example, the sequence:

                     .nr PS 10
                     .nr GROWPS 3
                     .nr PSINCR 1.5p
                     .NH 1
                     Top Level Heading
                     .NH 2
                     Second Level Heading
                     .NH 3
                     Third Level Heading

              will  cause  “1. Top Level Heading” to be printed in 13pt bold
              text, followed by “1.1. Second Level Heading” in  11.5pt  bold
              text,  while “1.1.1. Third Level Heading”, and all more deeply
              nested heading levels, will remain in the 10pt bold text which
              is specified by the PS register.

              Note  that  the value stored in PSINCR is interpreted in groff
              basic units; the p scaling factor  should  be  employed,  when
              assigning a value specified in points.

              The  style  used  to  represent  the  section number, within a
              numbered heading, is controlled by the SN-STYLE  string;  this
              may  be  set  to  either  the  SN-DOT  or the SN-NO-DOT style,
              (described  below),  by  aliasing  SN-STYLE  accordingly.   By
              default, SN-STYLE is initialised by defining the alias

                     .als SN-STYLE SN-DOT

              it  may  be  changed  to the SN-NO-DOT style, if preferred, by
              defining the alternative alias

                     .als SN-STYLE SN-NO-DOT

              Any such change becomes effective with the first use  of  .NH,
              after the new alias is defined.

              After  invoking  .NH, the assigned heading number is available
              in the strings SN-DOT (as it appears in the default formatting
              style   for  numbered  headings,  with  a  terminating  period
              following the number), and SN-NO-DOT  (with  this  terminating
              period  omitted).   The string SN is also defined, as an alias
              for SN-DOT; if preferred, the user may redefine it as an alias
              for SN-NO-DOT, by including the initialisation:

                     .als SN SN-NO-DOT

              at any time; the change becomes effective with the next use of
              .NH, after the new alias is defined.

       .SH [xx]
              Unnumbered subheading.  The use of the optional xx argument is
              a   GNU  extension,  which  adjusts  the  point  size  of  the
              unnumbered subheading to match that  of  a  numbered  heading,
              introduced  using  .NH xx  with  the  same  value  of xx.  For
              example, given the same settings for PS, GROWPS and PSINCR, as
              used in the preceding .NH example, the sequence:

                     .SH 2
                     An Unnumbered Subheading

              will print “An Unnumbered Subheading” in 11.5pt bold text.

       The  ms macros provide a variety of methods to highlight or emphasize

       .B [txt [post [pre]]]
              Sets its first argument in bold type.  If you specify a second
              argument,  groff prints it in the previous font after the bold
              text, with no  intervening  space  (this  allows  you  to  set
              punctuation  after  the  highlighted text without highlighting
              the punctuation).  Similarly, it prints the third argument (if
              any)  in  the  previous  font  before the first argument.  For

                     .B foo ) (

              prints (foo).

              If you give this macro no arguments,  groff  prints  all  text
              following  in  bold until the next highlighting, paragraph, or
              heading macro.

       .R [txt [post [pre]]]
              Sets its first  argument  in  roman  (or  regular)  type.   It
              operates similarly to the B macro otherwise.

       .I [txt [post [pre]]]
              Sets its first argument in italic type.  It operates similarly
              to the B macro otherwise.

       .CW [txt [post [pre]]]
              Sets its first argument in a constant width face.  It operates
              similarly to the B macro otherwise.

       .BI [txt [post [pre]]]
              Sets  its  first  argument  in  bold italic type.  It operates
              similarly to the B macro otherwise.

       .BX [txt]
              Prints its argument and draws a box around it.  If you want to
              box  a  string  that  contains spaces, use a digit-width space

       .UL [txt [post]]
              Prints its first argument with an underline.  If you specify a
              second  argument,  groff  prints it in the previous font after
              the underlined text, with no intervening space.

       .LG    Prints all text following in larger type (2 points larger than
              the   current   point   size)   until   the  next  font  size,
              highlighting, paragraph, or heading macro.   You  can  specify
              this macro multiple times to enlarge the point size as needed.

       .SM    Prints  all  text  following in smaller type (2 points smaller
              than the  current  point  size)  until  the  next  type  size,
              highlighting,  paragraph,  or  heading macro.  You can specify
              this macro multiple times to reduce the point size as needed.

       .NL    Prints all text following in the normal point size  (that  is,
              the value of the PS register).

              Print the enclosed text as a superscript.

       You  may  need to indent sections of text.  A typical use for indents
       is to create nested lists and sublists.

       Use the RS and RE macros to start and end a section of indented text,
       respectively.  The PI register controls the amount of indent.

       You can nest indented sections as deeply as needed by using multiple,
       nested pairs of RS and RE.

       The IP macro handles duties for all lists.  Its syntax is as follows:

       .IP [marker [width]]

              The marker is usually a bullet character  \(bu  for  unordered
              lists,  a  number  (or  auto-incrementing number register) for
              numbered lists, or a word or phrase  for  indented  (glossary-
              style) lists.

              The width specifies the indent for the body of each list item.
              Once specified, the indent remains the same for all list items
              in the document until specified again.

   Tab stops
       Use  the  ta request to set tab stops as needed.  Use the TA macro to
       reset tabs to the default (every 5n).  You can redefine the TA  macro
       to create a different set of default tab stops.

   Displays and keeps
       Use  displays  to  show  text-based examples or figures (such as code
       listings).  Displays turn off  filling,  so  lines  of  code  can  be
       displayed  as-is  without inserting br requests in between each line.
       Displays can be kept on a single page, or  allowed  to  break  across
       pages.  The following table shows the display types available.

                   Display macro                   Type of display
                With keep      No keep
              .DS L            .LD       Left-justified.
              .DS I [indent]   .ID       Indented (default indent in the DI
              .DS B            .BD       Block-centered (left-justified,
                                         longest line centered).
              .DS C            .CD       Centered.
              .DS R            .RD       Right-justified.

       Use  the DE macro to end any display type.  The macros Ds and De were
       formerly provided as aliases for DS and DE,  respectively,  but  they
       have been removed, and should no longer be used.  X11 documents which
       actually use Ds and De always load a specific macro file from the X11
       distribution (macros.t) which provides proper definitions for the two

       To keep text together on a page, such as a paragraph that refers to a
       table  (or list, or other item) immediately following, use the KS and
       KE macros.  The KS macro begins a block of  text  to  be  kept  on  a
       single page, and the KE macro ends the block.

       You  can  specify a floating keep using the KF and KE macros.  If the
       keep cannot fit on the current page, groff holds the contents of  the
       keep  and allows text following the keep (in the source file) to fill
       in the remainder of the current page.  When the page breaks,  whether
       by  an  explicit bp request or by reaching the end of the page, groff
       prints the floating keep at the top of the new page.  This is  useful
       for  printing  large  graphics  or  tables that do not need to appear
       exactly where specified.

       The macros B1 and B2 can be used to enclose a text within a box;  .B1
       begins  the  box,  and .B2 ends it.  Text in the box is automatically
       placed in a diversion (keep).

   Tables, figures, equations, and references
       The -ms macros support the standard groff  preprocessors:  tbl,  pic,
       eqn, and refer.  Mark text meant for preprocessors by enclosing it in
       pairs of tags as follows:

       .TS [H] and .TE
              Denotes a table, to be processed by the tbl preprocessor.  The
              optional H argument instructs groff to create a running header
              with the information up to the TH  macro.   Groff  prints  the
              header  at  the beginning of the table; if the table runs onto
              another page, groff prints the header  on  the  next  page  as

       .PS and .PE
              Denotes  a  graphic,  to be processed by the pic preprocessor.
              You can create a pic file by hand, using the AT&T  pic  manual
              available  on  the  Web as a reference, or by using a graphics
              program such as xfig.

       .EQ [align] and .EN
              Denotes an equation, to be processed by the eqn  preprocessor.
              The  optional  align argument can be C, L, or I to center (the
              default), left-justify, or indent the equation.

       .[ and .]
              Denotes  a  reference,  to   be   processed   by   the   refer
              preprocessor.    The  GNU  refer(1)  manual  page  provides  a
              comprehensive reference to the preprocessor and the format  of
              the bibliographic database.

       The  ms macros provide a flexible footnote system.  You can specify a
       numbered footnote by using the \** escape, followed by  the  text  of
       the footnote enclosed by FS and FE macros.

       You  can  specify  symbolic  footnotes  by placing the mark character
       (such as \(dg for the dagger character) in the body text, followed by
       the text of the footnote enclosed by FS \(dg and FE macros.

       You  can  control  how  groff prints footnote numbers by changing the
       value of the FF register as follows:

              0      Prints the footnote number as  a  superscript;  indents
                     the footnote (default).

              1      Prints  the  number  followed by a period (like 1.) and
                     indents the footnote.

              2      Like 1, without an indent.

              3      Like 1, but prints the footnote  number  as  a  hanging

       You  can  use  footnotes  safely within keeps and displays, but avoid
       using numbered footnotes within floating keeps.  You can set a second
       \**  between  a  \**  and  its corresponding .FS; as long as each .FS
       occurs after the corresponding \** and the occurrences of .FS are  in
       the same order as the corresponding occurrences of \**.

   Headers and footers
       There are three ways to define headers and footers:

       ·  Use  the strings LH, CH, and RH to set the left, center, and right
          headers; use LF, CF, and RF to set the  left,  center,  and  right
          footers.   This  works  best for documents that do not distinguish
          between odd and even pages.

       ·  Use the OH and EH macros to define headers for the  odd  and  even
          pages; and OF and EF macros to define footers for the odd and even
          pages.   This  is  more  flexible  than  defining  the  individual
          strings.  The syntax for these macros is as follows:

                 .OH 'left'center'right'

          You  can  replace  the  quote  (')  marks  with  any character not
          appearing in the header or footer text.

       You can also redefine the PT and BT macros to change the behavior  of
       the  header  and footer, respectively.  The header process also calls
       the (undefined) HD macro after PT ; you can define this macro if  you
       need additional processing after printing the header (for example, to
       draw a line below the header).

       You control margins using a set of number registers.   The  following
       table lists the register names and defaults:

              Reg.          Definition             Effective      Default
              PO     Page offset (left margin)   next page        1i
              LL     Line length                 next paragraph   6i
              LT     Header/footer length        next paragraph   6i
              HM     Top (header) margin         next page        1i
              FM     Bottom (footer) margin      next page        1i

       Note  that there is no right margin setting.  The combination of page
       offset and line length provide the information  necessary  to  derive
       the right margin.

   Multiple columns
       The  ms macros can set text in as many columns as will reasonably fit
       on the page.  The following macros are available.  All of them  force
       a  page break if a multi-column mode is already set.  However, if the
       current mode is single-column, starting a multi-column mode does  not
       force a page break.

       .1C    Single-column mode.

       .2C    Two-column mode.

       .MC [width [gutter]]
              Multi-column  mode.   If  you  specify  no  arguments,  it  is
              equivalent to the 2C macro.  Otherwise, width is the width  of
              each  column  and  gutter  is  the space between columns.  The
              MINGW number register is the default gutter width.

   Creating a table of contents
       Wrap text that you want to appear in the table of contents in XS  and
       XE  macros.   Use  the TC macro to print the table of contents at the
       end  of  the  document,  resetting  the  page  number  to  i   (Roman
       numeral 1).

       You  can  manually  create  a  table of contents by specifying a page
       number as the first argument to XS.  Add subsequent entries using the
       XA macro.  For example:

              .XS 1
              .XA 2
              A Brief History of the Universe
              .XA 729
              Details of Galactic Formation

       Use  the  PX  macro  to  print a manually-generated table of contents
       without resetting the page number.

       If you give the argument no to either  PX  or  TC,  groff  suppresses
       printing the title specified by the \*[TOC] string.

   Fractional point sizes
       Traditionally,  the  ms  macros  only  support integer values for the
       document's  font  size  and  vertical  spacing.   To  overcome   this
       restriction,  values  larger  than  or  equal  to  1000  are taken as
       fractional values, multiplied by 1000.  For example, ‘.nr  PS  10250’
       sets the font size to 10.25 points.

       The  following  four registers accept fractional point sizes: PS, VS,
       FPS, and FVS.

       Due to backwards compatibility, the value of VS must be smaller  than
       40000 (this is 40.0 points).

DIFFERENCES FROM troff ms         top

       The groff ms macros are a complete re-implementation, using no
       original AT&T code.  Since they take advantage of the extended
       features in groff, they cannot be used with AT&T troff.  Other
       differences include:

       ·  The internals of groff ms differ from the internals of Unix ms.
          Documents that depend upon implementation details of Unix ms may
          not format properly with groff ms.

       ·  The error-handling policy of groff ms is to detect and report
          errors, rather than silently to ignore them.

       ·  Some Bell Labs localisms are not implemented by default.  However,
          if you call the otherwise undocumented SC section-header macro,
          you will enable implementations of three other archaic Bell Labs
          macros: UC, P1, and P2.  These are not enabled by default because
          (a) they were not documented, in the original ms manual, and
          (b) the P1 and UC macros both collide with different macros in the
          Berkeley version of ms.

          These emulations are sufficient to give back the 1976 Kernighan &
          Cherry paper Typesetting Mathematics – User's Guide its section
          headings, and restore some text that had gone missing as arguments
          of undefined macros.  No warranty express or implied is given as
          to how well the typographic details these produce match the
          original Bell Labs macros.

       ·  Berkeley localisms, in particular the TM and CT macros, are not

       ·  Groff ms does not work in compatibility mode (e.g., with the -C

       ·  There is no support for typewriter-like devices.

       ·  Groff ms does not provide cut marks.

       ·  Multiple line spacing is not supported (use a larger vertical
          spacing instead).

       ·  Some Unix ms documentation says that the CW and GW number
          registers can be used to control the column width and gutter
          width, respectively.  These number registers are not used in groff

       ·  Macros that cause a reset (paragraphs, headings, etc.) may change
          the indent.  Macros that change the indent do not increment or
          decrement the indent, but rather set it absolutely.  This can
          cause problems for documents that define additional macros of
          their own.  The solution is to use not the in request but instead
          the RS and RE macros.

       ·  The number register GS is set to 1 by the groff ms macros, but is
          not used by the Unix ms macros.  Documents that need to determine
          whether they are being formatted with Unix ms or groff ms should
          use this number register.

       ·  To make groff ms use the default page offset (which also specifies
          the left margin), the PO number register must stay undefined until
          the first ms macro is evaluated.  This implies that PO should not
          be used early in the document, unless it is changed also: Remember
          that accessing an undefined register automatically defines it.

       You can redefine the following strings to adapt the groff ms macros
       to languages other than English:

                            String       Default Value
                          REFERENCES   References
                          ABSTRACT     ABSTRACT
                          TOC          Table of Contents
                          MONTH1       January
                          MONTH2       February
                          MONTH3       March
                          MONTH4       April
                          MONTH5       May
                          MONTH6       June
                          MONTH7       July
                          MONTH8       August
                          MONTH9       September
                          MONTH10      October
                          MONTH11      November
                          MONTH12      December

       The \*- string produces an em dash — like this.

       Use \*Q and \*U to get a left and right typographer's quote,
       respectively, in troff (and plain quotes in nroff).

   Text Settings
       The FAM string sets the default font family.  If this string is
       undefined at initialization, it is set to Times.

       The point size, vertical spacing, and inter-paragraph spacing for
       footnotes are controlled by the number registers FPS, FVS, and FPD;
       at initialization these are set to \n(PS-2, \n[FPS]+2, and \n(PD/2,
       respectively.  If any of these registers are defined before
       initialization, the initialization macro does not change them.

       The hyphenation flags (as set by the hy request) are set from the HY
       register; the default is 14.

       Improved accent marks (as originally defined in Berkeley's ms
       version) are available by specifying the AM macro at the beginning of
       your document.  You can place an accent over most characters by
       specifying the string defining the accent directly after the
       character.  For example, n\*~ produces an n with a tilde over it.


       The following conventions are used for names of macros, strings and
       number registers.  External names available to documents that use the
       groff ms macros contain only uppercase letters and digits.

       Internally the macros are divided into modules; naming conventions
       are as follows:

       ·  Names used only within one module are of the form module*name.

       ·  Names used outside the module in which they are defined are of the
          form module@name.

       ·  Names associated with a particular environment are of the form
          environment:name; these are used only within the par module.

       ·  name does not have a module prefix.

       ·  Constructed names used to implement arrays are of the form

       Thus the groff ms macros reserve the following names:

       ·  Names containing the characters *, @, and :.

       ·  Names containing only uppercase letters and digits.
