6 deroff - remove nroff/troff, tbl, and eqn constructs

9 deroff [-m [m | s | l]] [-w] [-i] [filename...]
10
13 deroff reads each of the filenames in sequence and removes all troff(1)
14 requests, macro calls, backslash constructs, eqn(1) constructs (between
15 .EQ and .EN lines, and between delimiters), and tbl(1) descriptions,
16 perhaps replacing them with white space (blanks and blank lines), and
17 writes the remainder of the file on the standard output. deroff follows
18 chains of included files (.so and .nx troff commands); if a file has
19 already been included, a .so naming that file is ignored and a .nx nam‐
20 ing that file terminates execution. If no input file is given, deroff
21 reads the standard input.

24 -m The -m option may be followed by an m, s, or l. The -mm option
25 causes the macros to be interpreted so that only running text is
26 output (that is, no text from macro lines.) The -ml option
27 forces the -mm option and also causes deletion of lists associ‐
28 ated with the mm macros.
29 -w If the -w option is given, the output is a word list, one
32 ``word'' per line, with all other characters deleted. Otherwise,
33 the output follows the original, with the deletions mentioned
34 above. In text, a ``word'' is any string that contains at least
35 two letters and is composed of letters, digits, ampersands (&),
36 and apostrophes ('); in a macro call, however, a ``word'' is a
37 string that begins with at least two letters and contains a total
38 of at least three letters. Delimiters are any characters other
39 than letters, digits, apostrophes, and ampersands. Trailing apos‐
40 trophes and ampersands are removed from ``words.''
41 -i The -i option causes deroff to ignore .so and .nx commands.

62 deroff is not a complete troff interpreter, so it can be confused by
63 subtle constructs. Most such errors result in too much rather than too
64 little output.
65 The -ml option does not handle nested lists correctly.
