DEROFF(CT) XENIX System V DEROFF(CT)
Name
deroff - Removes nroff/troff, tbl, and eqn constructs.
Syntax
deroff [ -w ] [ -mx ] [ files ]
Description
deroff reads each of the files in sequence and removes all
troff(CT) requests, macro calls, backslash constructs,
eqn(CT) constructs (between .EQ and .EN lines, and between
delimiters), and tbl(CT) descriptions. It writes the
remainder of the file on the standard output. deroff
follows chains of included files (.so and .nx troff
commands). If a file has already been included, a .so
naming that file is ignored and a .nx naming that file
terminates execution. If no input file is given, deroff
reads the standard input.
The -m option may be followed by an m, s, or l. The
resulting -mm or -ms option causes the MM or MS macros to be
interpreted so that only running text is output (i.e., no
text from macro lines). The -ml option forces the -mm
option and also causes deletion of lists associated with the
MM macros. This option is used by the diction(CT) command.
The -w option outputs a word list, one ``word'' per line,
with all other characters deleted. Otherwise, the output
follows the original, with the deletions mentioned above.
In text, a ``word'' is any string that contains at least two
letters and is composed of letters, digits, ampersands (&),
and apostrophes ('). In a macro call, however, a ``word''
is a string that begins with at least two letters and
contains a total of at least three letters. Delimiters are
any characters other than letters, digits, apostrophes, and
ampersands. Trailing apostrophes and ampersands are removed
from ``words.''

diction(CT), eqn(CT), style(CT), tbl(CT), troff(CT)
Notes
Since deroff is not a complete troff interpreter, it can
result in too much output.
The -ml option does not handle nested lists correctly.
deroff also removes words of two or fewer letters in lines
that begin with macro calls or troff requests.
