GROTTY(1)                                                            GROTTY(1)



NAME
       grotty - groff driver for typewriter-like devices

SYNOPSIS
       grotty [-hfbuodBUv ] [ -Fdir ] [ files...]

DESCRIPTION
       grotty translates the output of GNU troff into a form suitable for
       typewriter-like devices.  Normally grotty should invoked by using the
       groff command with a -Tascii or -Tlatin1 option.  If no files are
       given, grotty will read the standard input.  A filename of - will also
       cause grotty to read the standard input.  Output is written to the
       standard output.

       Normally grotty prints a bold character c using the sequence `c
       BACKSPACE c' and a italic character c by the sequence `_ BACKSPACE c'.
       These sequences can be displayed on a terminal by piping through ul(1).
       Pagers such as more(1) or less(1) are also able to display these
       sequences.  Use either -B or -U when piping into less(1); use -b when
       piping into more(1). There is no need to filter the output through
       col(1) since grotty never outputs reverse line feeds.

       The font description file may contain a command


              internalname n

       where n is a decimal integer.  If the 01 bit in n is set, then the font
       will be treated as an italic font; if the 02 bit is set, then it will
       be treated as a bold font.  The code field in the font description
       field gives the code which will be used to output the character.  This
       code can also be used in the \N escape sequence in troff.

OPTIONS
       -Fdir  Search the directory dir/devname for font and device description
              files; name is the name of the device, usually ascii or latin1.

       -h     Use horizontal tabs in the output.  Tabs are assumed to be set
              every 8 columns.

       -f     Use form feeds in the output.  A form feed will be output at the
              end of each page that has no output on its last line.

       -b     Suppress the use of overstriking for bold characters.

       -u     Suppress the use of underlining for italic characters.

       -B     Use only overstriking for bold-italic characters.

       -U     Use only underlining for bold-italic characters.

       -o     Suppress overstriking (other than for bold or underlined
              characters).

       -d     Ignore all \D commands.  Without this grotty will render
              \D'l...' commands that have at least at least one zero argument
              (and so are either horizontal or vertical) using -, | and +
              characters.

       -v     Print the version number.

FILES
       /usr/local/share/groff_font/devascii/DESC
              Device description file for ascii device.

       /usr/local/share/groff_font/devascii/ F
              Font description file for font F of ascii device.

       /usr/local/share/groff_font/devlatin1/DESC
              Device description file for latin1 device.

       /usr/local/share/groff_font/devlatin1/ F
              Font description file for font F of latin1 device.

       /usr/local/share/tmac/tmac.tty
              Macros for use with grotty.

       /usr/local/share/tmac/tmac.tty-char
              Additional klugey character definitions for use with grotty.

BUGS
       grotty is intended only for simple documents.

       There is no support for fractional horizontal or vertical motions.

       There is no support for \D commands other than horizontal and vertical
       lines.

       Characters above the first line (ie with a vertical position of 0)
       cannot be printed.
