grotty - groff driver for typewriter-like devices
grotty [ -hfbuodBUv ] [ -Fdir ] [ files... ]
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
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 escape sequence in troff.
-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
-d Ignore allgrotty will
render '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.
Device description file for ascii device.
Font description file for font F of ascii device.
Device description file for latin1 device.
Font description file for font F of latin1 device.
