DEROFF(1) — HP-UX
NAME
deroff − remove nroff, tbl, and eqn constructs
SYNOPSIS
deroff [−mx] [−w] [−i] [ file ... ]
DESCRIPTION
Deroff reads each file in sequence and removes all nroff requests, macro calls, backslash constructs, eqn constructs (between .EQ and .EN lines, and between delimiters), and tbl(1) descriptions, 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 nroff 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 can be followed by an m, s, or l. The −mm option causes the macros 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.
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.”
If the −i option is given, deroff ignores the .so and .nx nroff commands.
WARNINGS
Deroff is not a complete nroff interpreter; thus 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.
