26 ;;; Commentary:
28 ;; This code provides a function, `man', with which you can browse
29 ;; UNIX manual pages. Formatting is done in background so that you
30 ;; can continue to use your Emacs while processing is going on.
31 ;;
32 ;; The mode also supports hypertext-like following of manual page SEE
33 ;; ALSO references, and other features. See below or do `?' in a
34 ;; manual page buffer for details.
36 ;; ========== Credits and History ==========
37 ;; In mid 1991, several people posted some interesting improvements to
38 ;; man.el from the standard Emacs 18.57 distribution. I liked many of
39 ;; these, but wanted everything in one single package, so I decided
40 ;; to incorporate them into a single manual browsing mode. While
41 ;; much of the code here has been rewritten, and some features added,
42 ;; these folks deserve lots of credit for providing the initial
43 ;; excellent packages on which this one is based.
45 ;; Nick Duffek <duffek@chaos.cs.brandeis.edu>, posted a very nice
46 ;; improvement which retrieved and cleaned the manpages in a
47 ;; background process, and which correctly deciphered such options as
48 ;; man -k.
50 ;; Eric Rose <erose@jessica.stanford.edu>, submitted manual.el which
51 ;; provided a very nice manual browsing mode.
53 ;; This package was available as `superman.el' from the LCD package
54 ;; for some time before it was accepted into Emacs 19. The entry
55 ;; point and some other names have been changed to make it a drop-in
56 ;; replacement for the old man.el package.
58 ;; Francesco Potortì <pot@cnuce.cnr.it> cleaned it up thoroughly,
59 ;; making it faster, more robust and more tolerant of different
60 ;; systems' man idiosyncrasies.
62 ;; ========== Features ==========
63 ;; + Runs "man" in the background and pipes the results through a
64 ;; series of sed and awk scripts so that all retrieving and cleaning
65 ;; is done in the background. The cleaning commands are configurable.
66 ;; + Syntax is the same as Un*x man
67 ;; + Functionality is the same as Un*x man, including "man -k" and
68 ;; "man <section>", etc.
69 ;; + Provides a manual browsing mode with keybindings for traversing
70 ;; the sections of a manpage, following references in the SEE ALSO
71 ;; section, and more.
72 ;; + Multiple manpages created with the same man command are put into
73 ;; a narrowed buffer circular list.
75 ;; ============= TODO ===========
76 ;; - Add a command for printing.
77 ;; - The awk script deletes multiple blank lines. This behavior does
78 ;; not allow one to understand if there was indeed a blank line at the
79 ;; end or beginning of a page (after the header, or before the
80 ;; footer). A different algorithm should be used. It is easy to
81 ;; compute how many blank lines there are before and after the page
82 ;; headers, and after the page footer. But it is possible to compute
83 ;; the number of blank lines before the page footer by heuristics
84 ;; only. Is it worth doing?
85 ;; - Allow a user option to mean that all the manpages should go in
86 ;; the same buffer, where they can be browsed with M-n and M-p.
