DEROFF (l) DEROFF (l)
NAME
derofi - remove nrofi/trofi, tbl, and eqn constructs
SYNOPSIS
deroff [ -mx I [ -w I [ files I
DESCRIPTION
Deroff reads each of the files in sequence and removes all troff
requests, macro calls, backslash constructs, eqn(1) constructs
(between .EQ and .EN lines, and between delimiters), and tbl(1)
descriptions, perhaps replacing them with white space (blanks and
blank lines), and 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 I. The -mm
option causes the macros 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.
If the -w option is given, the output is 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."
SEE ALSO
eqn( 1 ), nrofi( 1 ), tbl( 1 ).
BUGS
Deroff is not a complete troff interpreter, so it can be confused by
subtle constructs. Most such errors result in too much rather than
too little output.
The -ml option does not handle nested lists correctly.
