GROTTY(1)GROTTY(1)NAMEgrotty - groff driver for typewriter-like devices
SYNOPSISgrotty [ -hfbuodBUv ] [ -Fdir ] [ files... ]
It is possible to have whitespace between the -F option and its parame‐
ter.
DESCRIPTIONgrotty translates the output of GNU troff into a form suitable for
typewriter-like devices. Normally grotty should be invoked by using
the groff command with a -Tascii, -Tlatin1 or -Tutf8 option on ASCII
based systems, and with -Tcp1047 on EBCDIC based hosts. 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 Prepend directory dir/devname to the search path for font and
device description files; name is the name of the device, usu‐
ally ascii, latin1, utf8, or cp1047.
-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 charac‐
ters).
-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.
