The command line is parsed according to the usual GNU convention.
.
The whitespace between a command line option and its argument is
optional.
.
Options can be grouped behind a single
.ShortOpt
(minus character).
.
A filename of
.ShortOpt
(minus character) denotes the standard input.

--------------------------------------------------------------------
. This document describes the groff program, the main front-end for the groff document formatting system. . The groff program and macro suite is the implementation of a roff (@MAN7EXT@) system within the free software collection RL http://\:www.gnu.org "GNU" . . The groff system has all features of the classical roff , but adds many extensions. .
The
groff program allows to control the whole
groff system by command line options.
.
This is a great simplification in comparison to the classical case (which
uses pipes only).
.
.
--------------------------------------------------------------------
. As groff is a wrapper program for @g@troff both programs share a set of options. . But the groff program has some additional, native options and gives a new meaning to some @g@troff options. . On the other hand, not all @g@troff options can be fed into groff . . . --------------------------------------------------------------------
. The following options either do not exist for @g@troff or are differently interpreted by groff . . . .OptDef e Preprocess with @g@eqn . . . .OptDef g Preprocess with @g@grn . . . .OptDef G Preprocess with grap . . . .OptDef h help Print a help message. . . .OptDef I "" dir This option may be used to specify a directory to search for files (both those on the command line and those named in .psbb and .so requests, and \eX'ps: import' and \eX'ps: file' escapes). The current directory is always searched first. This option may be specified more than once; the directories will be searched in the order specified. No directory search is performed for files specified using an absolute path. This option implies the .ShortOpt s option. . . .OptDef l Send the output to a spooler program for printing. . The command that should be used for this is specified by the print command in the device description file, see \%groff_font (@MAN5EXT@). If this command is not present, the output is piped into the lpr (1) program by default. . See options .ShortOpt L and .ShortOpt X . . . .OptDef L "" arg Pass arg to the spooler program. Several arguments should be passed with a separate .ShortOpt L option each. . Note that groff does not prepend .ShortOpt\" just a minus sign (a minus sign) to arg before passing it to the spooler program. . . .OptDef N Don't allow newlines within eqn delimiters. . This is the same as the .ShortOpt N option in @g@eqn . . . .OptDef p Preprocess with @g@pic . . . .OptDef P "" "\*[@-]option" .OptDef+ P "" "\*[@-]option \f[CB]\*[@-]P\f[] arg" Pass \*[@-]option or \*[@-]option arg to the postprocessor. . The option must be specified with the necessary preceding minus sign(s) .Quoted \*[@-] or .Quoted \*[@--] because groff does not prepend any dashes before passing it to the postprocessor. . For example, to pass a title to the \%gxditview postprocessor, the shell command .ShellCommand groff \*[@-]X \*[@-]P \*[@-]title \*[@-]P 'groff it' \f[I]foo\f[] is equivalent to .ShellCommand groff \*[@-]X \*[@-]Z \f[I]foo\f[] | \ gxditview \*[@-]title 'groff it' \*[@-] . . .OptDef R Preprocess with @g@refer . . No mechanism is provided for passing arguments to @g@refer because most @g@refer options have equivalent language elements that can be specified within the document. . See \%@g@refer (@MAN1EXT@) for more details. . . .OptDef s Preprocess with @g@soelim . . . .OptDef S Safer mode. . Pass the .ShortOpt S option to @g@pic and disable the following @g@troff requests: .open , .opena , .pso , .sy , and .pi . For security reasons, safer mode is enabled by default. . . .OptDef t Preprocess with @g@tbl . . . .OptDef T "" dev Set output device to dev . For this device, @g@troff generates the intermediate output ; see \%groff_out (@MAN5EXT@). . Then groff calls a postprocessor to convert @g@troff 's intermediate output to its final format. . Real devices in groff are .
. The following options are transparently handed over to the formatter program @g@troff that is called by groff subsequently. . These options are described in more detail in @g@troff (@MAN1EXT@). . .OptDef a ascii approximation of output. . .OptDef b backtrace on error or warning. . .OptDef c disable color output. . Please consult the \%grotty (@MAN1EXT@) man page for more details. . .OptDef C enable compatibility mode. . .OptDef d "" cs .OptDef+ d "" name=s define string. . .OptDef E disable @g@troff error messages. . .OptDef f "" fam set default font family. . .OptDef F "" dir set path for font DESC files. . .OptDef i process standard input after the specified input files. . .OptDef m "" name include macro file \f[I]name\f[]\f[B].tmac\f[] (or \f[B]tmac.\f[]\f[I]name\f[]); see also \%groff_tmac (@MAN5EXT@). . .OptDef M "" dir path for macro files. . .OptDef n "" num number the first page num . . .OptDef o "" list output only pages in list . . .OptDef r "" cn .OptDef+ r "" name=n set number register. . .OptDef w "" name enable warning name . . .OptDef W "" name disable warning name . . . --------------------------------------------------------------------
. The groff system implements the infrastructure of classical roff; see roff (@MAN7EXT@) for a survey on how a roff system works in general. . Due to the front-end programs available within the groff system, using groff is much easier than "classical roff" . . This section gives an overview of the parts that constitute the groff system. . It complements roff (@MAN7EXT@) with groff-specific features. . This section can be regarded as a guide to the documentation around the groff system. . . --------------------------------------------------------------------
. The virtual paper size used by troff to format the input is controlled globally with the requests .po , .pl , and .ll . See groff_tmac (@MAN5EXT@) for the `papersize' macro package which provides a convenient interface. .
The physical paper size, giving the actual dimensions of the paper sheets, is controlled by output devices like grops with the command line options -p and -l . See groff_font (@MAN5EXT@) and the man pages of the output devices for more details. groff uses the command line option -P to pass options to output devices; for example, the following selects A4 paper in landscape orientation for the PS device: .
groff -Tps -P-pa4 -P-l .\|.\|.
. The groff program is a wrapper around the @g@troff (@MAN1EXT@) program. . It allows to specify the preprocessors by command line options and automatically runs the postprocessor that is appropriate for the selected device. . Doing so, the sometimes tedious piping mechanism of classical roff (@MAN7EXT@) can be avoided. .
The grog (@MAN1EXT@) program can be used for guessing the correct groff command line to format a file. .
The
\%groffer (@MAN1EXT@) program is an allround-viewer for groff files and man pages.
.
.
--------------------------------------------------------------------
. The groff preprocessors are reimplementations of the classical preprocessors with moderate extensions. . The preprocessors distributed with the groff package are .
@g@eqn (@MAN1EXT@) for mathematical formul\(ae,
@g@grn (@MAN1EXT@) for including gremlin (1) pictures,
@g@pic (@MAN1EXT@) for drawing diagrams,
\%@g@refer (@MAN1EXT@) for bibliographic references,
\%@g@soelim (@MAN1EXT@) for including macro files from standard locations, .
and
@g@tbl (@MAN1EXT@) for tables. .
Besides these, there are some internal preprocessors that are
automatically run with some devices.
.
These aren't visible to the user.
.
.
--------------------------------------------------------------------
. Macro packages can be included by option .ShortOpt m . . The groff system implements and extends all classical macro packages in a compatible way and adds some packages of its own. . Actually, the following macro packages come with groff : .
man The traditional man page format; see \%groff_man (@MAN7EXT@). It can be specified on the command line as .ShortOpt man or .ShortOpt m man . .
mandoc The general package for man pages; it automatically recognizes whether the documents uses the man or the mdoc format and branches to the corresponding macro package. . It can be specified on the command line as .ShortOpt mandoc or .ShortOpt m mandoc . .
mdoc The BSD-style man page format; see \%groff_mdoc (@MAN7EXT@). It can be specified on the command line as .ShortOpt mdoc or .ShortOpt m mdoc . .
me The classical me document format; see \%groff_me (@MAN7EXT@). It can be specified on the command line as .ShortOpt me or .ShortOpt m me . .
mm The classical mm document format; see \%groff_mm (@MAN7EXT@). It can be specified on the command line as .ShortOpt mm or .ShortOpt m mm . .
ms The classical ms document format; see \%groff_ms (@MAN7EXT@). It can be specified on the command line as .ShortOpt ms or .ShortOpt m ms . .
www HTML-like macros for inclusion in arbitrary groff documents; see \%groff_www (@MAN7EXT@). .
Details on the naming of macro files and their placement can be found
in
\%groff_tmac (@MAN5EXT@); this man page also documents some other, minor auxiliary macro packages
not mentioned here.
.
.
--------------------------------------------------------------------
. General concepts common to all roff programming languages are described in roff (@MAN7EXT@). .
The groff extensions to the classical troff language are documented in \%groff_diff (@MAN7EXT@). .
The groff language as a whole is described in the (still incomplete)
"groff info file" ; a short (but complete) reference can be found in
groff (@MAN7EXT@). .
.
--------------------------------------------------------------------
. The central roff formatter within the groff system is @g@troff (@MAN1EXT@). It provides the features of both the classical troff and nroff, as well as the groff extensions. . The command line option .ShortOpt C switches @g@troff into "compatibility mode" which tries to emulate classical roff as much as possible. .
There is a shell script @g@nroff (@MAN1EXT@) that emulates the behavior of classical nroff. . It tries to automatically select the proper output encoding, according to the current locale. .
The formatter program generates
"intermediate output" ; see
\%groff_out (@MAN7EXT@). .
.
--------------------------------------------------------------------
. In roff, the output targets are called devices . A device can be a piece of hardware, e.g. a printer, or a software file format. . A device is specified by the option .ShortOpt T . The groff devices are as follows. .
ascii Text output using the ascii (7) character set. .
cp1047 Text output using the EBCDIC code page IBM cp1047 (e.g. OS/390 Unix). .
dvi TeX DVI format. .
html HTML output. .
latin1 Text output using the ISO \%Latin-1 (ISO \%8859-1) character set; see \%iso_8859_1 (7). .
lbp Output for Canon CAPSL printers (\%LBP-4 and \%LBP-8 series laser printers). .
lj4 HP LaserJet4-compatible (or other PCL5-compatible) printers. .
ps PostScript output; suitable for printers and previewers like gv (1). .
utf8 Text output using the Unicode (ISO 10646) character set with \%UTF-8 encoding; see unicode (7). .
X75 75dpi X Window System output suitable for the previewers \%xditview (1x) and \%gxditview (@MAN1EXT@). A variant for a 12\|pt document base font is \%X75-12 . .
X100 100dpi X Window System output suitable for the previewers \%xditview (1x) and \%gxditview (@MAN1EXT@). A variant for a 12\|pt document base font is \%X100-12 . .
The postprocessor to be used for a device is specified by the postpro command in the device description file; see \%groff_font (@MAN5EXT@). . This can be overridden with the \*[@-]X option. .
The default device is
@DEVICE@ . .
.
--------------------------------------------------------------------
. groff provides 3\~hardware postprocessors: .
\%grolbp (@MAN1EXT@) for some Canon printers,
\%grolj4 (@MAN1EXT@) for printers compatible to the HP LaserJet\~4 and PCL5,
\%grotty (@MAN1EXT@) for text output using various encodings, e.g. on text-oriented terminals or line-printers. .
Today, most printing or drawing hardware is handled by the operating system, by device drivers, or by software interfaces, usually accepting PostScript. . Consequently, there isn't an urgent need for more hardware device postprocessors. .
The groff software devices for conversion into other document file formats are .
\%grodvi (@MAN1EXT@) for the DVI format,
\%grohtml (@MAN1EXT@) for HTML format,
grops (@MAN1EXT@) for PostScript. .
Combined with the many existing free conversion tools this should
be sufficient to convert a troff document into virtually any existing
data format.
.
.
--------------------------------------------------------------------
. The following utility programs around groff are available. .
\%addftinfo (@MAN1EXT@) Add information to troff font description files for use with groff. .
\%afmtodit (@MAN1EXT@) Create font description files for PostScript device. .
\%groffer (@MAN1EXT@) General viewer program for groff files and man pages. .
\%gxditview (@MAN1EXT@) The groff X viewer, the GNU version of xditview. .
\%hpftodit (@MAN1EXT@) Create font description files for lj4 device. .
\%indxbib (@MAN1EXT@) Make inverted index for bibliographic databases. .
lkbib (@MAN1EXT@) Search bibliographic databases. .
\%lookbib (@MAN1EXT@) Interactively search bibliographic databases. .
\%pfbtops (@MAN1EXT@) Translate a PostScript font in .pfb format to ASCII. .
\%tfmtodit (@MAN1EXT@) Create font description files for TeX DVI device. .
\%xditview (1x) roff viewer distributed with X window.
.
.
--------------------------------------------------------------------
. Normally, the path separator in the following environment variables is the colon; this may vary depending on the operating system. . For example, DOS and Windows use a semicolon instead. .
.EnvVar GROFF_BIN_PATH This search path, followed by .EnvVar $PATH , will be used for commands that are executed by groff . . If it is not set then the directory where the groff binaries were installed is prepended to .EnvVar PATH . .
.EnvVar GROFF_COMMAND_PREFIX When there is a need to run different roff implementations at the same time groff provides the facility to prepend a prefix to most of its programs that could provoke name clashings at run time (default is to have none). . Historically, this prefix was the character g , but it can be anything. . For example, gtroff stood for groff 's troff , gtbl for the groff version of tbl . . By setting .EnvVar GROFF_COMMAND_PREFIX to different values, the different roff installations can be addressed. . More exactly, if it is set to prefix xxx then groff as a wrapper program will internally call xxx troff instead of troff . This also applies to the preprocessors \%eqn , \%grn , \%pic , \%refer , \%tbl , \%soelim , and to the utilities \%@g@indxbib and \%@g@lookbib . . This feature does not apply to any programs different from the ones above (most notably groff itself) since they are unique to the groff package. . .
.EnvVar GROFF_FONT_PATH A list of directories in which to search for the dev name directory in addition to the default ones. . See @g@troff (@MAN1EXT@) and \%groff_font (@MAN5EXT@) for more details. . .
.EnvVar GROFF_TMAC_PATH A list of directories in which to search for macro files in addition to the default directories. . See @g@troff (@MAN1EXT@) and \%groff_tmac (@MAN5EXT@) for more details. . .
.EnvVar GROFF_TMPDIR The directory in which temporary files will be created. . If this is not set but the environment variable .EnvVar TMPDIR instead, temporary files will be created in the directory .EnvVar $TMPDIR . On MS-DOS and Windows 32 platforms, the environment variables .EnvVar TMP and .EnvVar TEMP (in that order) are searched also, after .EnvVar GROFF_TMPDIR and .EnvVar TMPDIR . . Otherwise, temporary files will be created in /tmp . The \%@g@refer (@MAN1EXT@), \%groffer (@MAN1EXT@), \%grohtml (@MAN1EXT@), and grops (@MAN1EXT@) commands use temporary files. . .
.EnvVar GROFF_TYPESETTER
Preset the default device.
.
If this is not set the
@DEVICE@ device is used as default.
.
This device name is overwritten by the option
.ShortOpt T .
.
.
--------------------------------------------------------------------
. There are some directories in which groff installs all of its data files. . Due to different installation habits on different operating systems, their locations are not absolutely fixed, but their function is clearly defined and coincides on all systems. . . --------------------------------------------------------------------
. This contains all information related to macro packages. . Note that more than a single directory is searched for those files as documented in \%groff_tmac (@MAN5EXT@). . For the groff installation corresponding to this document, it is located at @MACRODIR@ . . The following files contained in the groff macro directory have a special meaning: . .
troffrc Initialization file for troff. . This is interpreted by @g@troff before reading the macro sets and any input. . .
troffrc-end Final startup file for troff, it is parsed after all macro sets have been read. . .
name .tmac
+
tmac. name Macro file for macro package
name . .
.
--------------------------------------------------------------------
. This contains all information related to output devices. . Note that more than a single directory is searched for those files; see @g@troff (@MAN1EXT@). . For the groff installation corresponding to this document, it is located at @FONTDIR@ . . The following files contained in the groff font directory have a special meaning: . .
dev name /DESC Device description file for device name , see \%groff_font (@MAN5EXT@). . .
dev name / F Font file for font
F of device
name . .
.
--------------------------------------------------------------------
. The following example illustrates the power of the groff program as a wrapper around @g@troff . .
To process a roff file using the preprocessors tbl and pic and the me macro set, classical troff had to be called by .
.ShellCommand pic foo.me | tbl | troff \*[@-]me \*[@-]Tlatin1 | grotty .
Using groff , this pipe can be shortened to the equivalent command
.ShellCommand groff \*[@-]p \*[@-]t \*[@-]me \*[@-]T latin1 foo.me .
An even easier way to call this is to use grog (@MAN1EXT@) to guess the preprocessor and macro options and execute the generated command (by using backquotes to specify shell command substitution)
.ShellCommand \`grog \*[@-]Tlatin1 foo.me\` .
The simplest way is to view the contents in an automated way by calling .
.ShellCommand groffer foo.me
.
.
--------------------------------------------------------------------
.
On EBCDIC hosts (e.g. OS/390 Unix), output devices ascii and latin1 aren't available. . Similarly, output for EBCDIC code page cp1047 is not available on ASCII based operating systems. .
