DEROFF(1) General Commands Manual DEROFF(1) NAME
deroff, delatex - remove formatting requests SYNOPSIS
deroff [ option ... ] file ... delatex file DESCRIPTION
Deroff reads each file in sequence and removes all nroff and troff(1) requests and non-text arguments, backslash constructions, and con- structs of preprocessors such as eqn(1), pic(1), and tbl(1). Remaining text is written on the standard output. Deroff follows files included by and commands; if a file has already been included, a for that file is ignored and a terminates execution. If no input file is given, deroff reads from standard input. The options are -w Output a word list, one `word' (string of letters, digits, and properly embedded ampersands and apostrophes, beginning with a let- ter) per line. Other characters are skipped. Otherwise, the output follows the original, with the deletions mentioned above. -i Ignore and requests. -ms -mm Remove titles, attachments, etc., as well as ordinary troff constructs, from ms(6) or mm documents. -ml Same as -mm, but remove lists as well. Delatex does for tex and latex (see tex(1)) files what deroff -wi does for troff files. SOURCE

troff(1), tex(1), spell(1) BUGS
These filters are not complete interpreters of troff or tex. For example, macro definitions containing cause chaos in deroff when the pop- ular delimiters for eqn are in effect. Text inside macros is emitted at place of definition, not place of call. DEROFF(1)

deroff(1) User Commands deroff(1) NAME
deroff - remove nroff/troff, tbl, and eqn constructs SYNOPSIS
deroff [ -m [m | s | l] ] [-w] [-i] [ filename...] DESCRIPTION
deroff reads each of the filenames in sequence and removes all troff(1) 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. OPTIONS
-m The -m option may be followed by an m, s, or l. The -mm option causes the macros to be interpreted so that only running text is output (that is, no text from macro lines.) The -ml option forces the -mm option and also causes deletion of lists associated with the mm macros. -w 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 let- ters 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.'' -i The -i option causes deroff to ignore .so and .nx commands. ATTRIBUTES

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. SunOS 5.10 14 Sep 1992 deroff(1)
