|
|
.SH NAME
|
|
grotty \- groff driver for typewriter-like devices
|
|
.SH SYNOPSIS
|
|
.B grotty
|
|
[
|
|
.B \-hfbuodBUv
|
|
] [
|
|
.BI \-F dir
|
|
] [

|
|
.SH DESCRIPTION
|
|
.B grotty
|
|
translates the output of GNU
|
|
.B troff
|
|
into a form suitable for typewriter-like devices.
|
|
Normally
|
|
.B grotty
|
|
should invoked by using the
|
|
.B groff
|
|
command
|
|
with a
|
|
.B \-Tascii
|
|
or
|
|
.B \-Tlatin1
|
|
option.
|
|
If no files are given,
|
|
.B grotty
|
|
will read the standard input.
|
|
A filename of
|
|
.B \-
|
|
will also cause
|
|
.B grotty
|
|
to read the standard input.
|
|
Output is written to the standard output.
|
|
.LP
|
|
Normally
|
|
.B grotty
|
|
prints a bold character
|
|
.I c
|
|
using the sequence
|
|
.RI ` c
|
|
.SM BACKSPACE
|
|
.IR c '
|
|
and a italic character
|
|
.I c
|
|
by the sequence
|
|
.RB ` _
|
|
.SM BACKSPACE
|
|
.IR c '.
|
|
These sequences can be displayed on a terminal
|
|
by piping through
|
|
.BR ul (1).
|
|
Pagers such as
|
|
.BR more (1)
|
|
or
|
|
.BR less (1)
|
|
are also able to display these sequences.
|
|
Use either
|
|
.B \-B
|
|
or
|
|
.B \-U
|
|
when piping into
|
|
.BR less (1);
|
|
use
|
|
.B \-b
|
|
when piping into
|
|
.BR more (1).
|
|
There is no need to filter the output through
|
|
.BR col (1)
|
|
since
|
|
.B grotty
|
|
never outputs reverse line feeds.
|
|
.LP
|
|
The font description file may contain a command
|
|
.IP
|
|
.BI internalname\ n
|
|
.LP
|
|
where
|
|
.I n
|
|
is a decimal integer.
|
|
If the 01 bit in
|
|
.I 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
|
|
.B \eN
|
|
escape sequence in
|
|
.BR troff .
