25;;; Commentary:
26
27;; This file has been obsolete since Emacs 22.1.
28
29;; Floating point numbers are represented by dot-pairs (mant . exp)
30;; where mant is the 24-bit signed integral mantissa and exp is the
31;; base 2 exponent.
32;;
33;; Emacs LISP supports a 24-bit signed integer data type, which has a
34;; range of -(2**23) to +(2**23)-1, or -8388608 to 8388607 decimal.
35;; This gives six significant decimal digit accuracy. Exponents can
36;; be anything in the range -(2**23) to +(2**23)-1.
37;;
38;; User interface:
39;; function f converts from integer to floating point
40;; function string-to-float converts from string to floating point
41;; function fint converts a floating point to integer (with truncation)
42;; function float-to-string converts from floating point to string
43;;
44;; Caveats:
45;; - Exponents outside of the range of +/-100 or so will cause certain
46;; functions (especially conversion routines) to take forever.
47;; - Very little checking is done for fixed point overflow/underflow.
48;; - No checking is done for over/underflow of the exponent
49;; (hardly necessary when exponent can be 2**23).

56;; GENERAL OVERVIEW
57;;
58;; This package installs numerous hooks to colorfully highlight your
59;; source code buffers as well as mail and news buffers. Most
60;; programming languages have predefined highlighting patterns.
61;; Just load hilit19 and files will be automatically highlighted as
62;; they're loaded.
63;;
64;; Rehighlight a buffer by typing C-S-l (control-shift-lowercase-L).
65;;
66;; If, when you edit the buffer, the coloring gets messed up, just
67;; redraw and the coloring will be adjusted. If automatic highlighting
68;; in the current buffer has been turned off, then typing C-u C-S-l will
69;; force a rehighlight of the entire buffer.
70;;
71;; Hilit19 can build faces by examining the names that you give to them
72;; For example, green/black-bold-italic-underline would be created as
73;; a face with a green foreground, and a black background, using a
74;; bold-italic font...with underlining for good measure.
75;;
76;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
77;;
78;; SETUP -- In your .emacs:
79;;
80;;
81;; (cond (window-system
82;; (setq hilit-mode-enable-list '(not text-mode)
83;; hilit-background-mode 'light
84;; hilit-inhibit-hooks nil
85;; hilit-inhibit-rebinding nil)
86;;
87;; (require 'hilit19)
88;; ))
89;;
90;; If you like font-lock-mode and want to use both packages, then you can
91;; disable hilit for the modes in which you want to use font-lock by listing
92;; said modes in hilit-mode-enable-list.
93;;
94;; (hilit-translate type 'RoyalBlue ; enable highlighting in C/C++
95;; string nil) ; disable string highlighting
96;;
97;; To get 100% of the utility of hilit19, you may also have to apply the
98;; patches below for info.el and vm5.33L_19/vm-summary.el
99;;
100;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
101;;
102;; SETUP -- Are you using the right font for Emacs?
103;;
104;; Emacs cannot properly find bold and italic fonts unless you specify a
105;; verbose X11 font name. If you specify a font for emacs in your
106;; .Xdefaults, it *MUST* be specified using the long form of the font name.
107;; Here's a good font menu:
108;;
109;; (setq
110;; x-fixed-font-alist
111;; '("Font Menu"
112;; ("Misc"
113;; ("6x12" "-misc-fixed-medium-r-semicondensed--12-110-75-75-c-60-*-1")

140;; * unbalanced, unescaped double quote characters can confuse hilit19.
141;; This will be fixed someday, so don't bug me about it.
142;;
143;; * ALTHOUGH HILIT19 IS FASTER THAN FONT-LOCK-MODE...
144;; For various reasons, the speed of the package could still stand to be
145;; improved. If you care to do a little profiling and make things tighter...
146;;
147;; * hilit-toggle-highlight is flaky when auto-rehighlight is neither t nor nil.
148;; Does anyone actually USE this? I think I might just remove it.

150;; PROJECTS THAT YOU CAN TAKE OVER BECAUSE I DON'T MUCH CARE ABOUT THEM...

152;; * Moved hilit-wysiwyg-replace here from my version of man.el, this is not

188;;
189;; Revision 2.16 1993/08/22 19:46:00 stig
190;; bug fix for next-overlay-change and accompanying change to
191;; hilit-unhighlight-region
192;;
193;; Revision 2.15 1993/08/20 12:16:22 stig
194;; minor change to fortran patterns
195;;
196;; Revision 2.14 1993/08/17 14:12:10 stig
197;; added default face mapping for 'formula' which is needed for new latex
198;; patterns.
199;;

204;;
205;; Revision 2.12 1993/08/16 00:16:41 stig
206;; changed references to default-bold-italic to just bold-italic because the
207;; font for that face is maintained by emacs.
208;;
209;; the pattern matcher now starts its searches from the end of the most
210;; recently highlighted region (which is not necessarily the end of the most
211;; recently matched regex).
212;;
213;; multiple errors in pattern matcher now just give an error instead of lots of
214;; annoying messages and dings.
215;;
216;; no longer use vm-summary-mode-hooks.
217;;
218;; some code moved from hilit-highlight-region to hilit-set-mode-patterns.
219;; This will affect you if you pass your patterns directly to
220;; hilit-highlight-region....use a pseudo-mode instead.

233;;
234;; Revision 2.9 1993/08/13 08:44:22 stig

260;; Revision 2.5 1993/07/28 05:02:56 stig
261;; improvements to makefile regular expressions
262;; removed about 130 lines just by compacting the big defconst for
263;; hilit-face-translation-table into a mapcar and defining a separate table
264;; of default faces.
265;;
266;; Revision 2.4 1993/07/27 14:09:05 stig
267;; documented another "known problem" to "head off gripe mail at the pass."
268;;
269;; Revision 2.3 1993/07/27 02:15:49 stig
270;; (hilit-lookup-face-create) incorporated patch which improves its behavior
271;; with more than one frame... Still can't have bold on the same face in two

289;; added hilit-parser-alist which can be used to apply different patterns to
290;; different parts of a buffer. This could be integrated in a far more
291;; elegant manner, but it presently serves the purpose of not applying

1502;; as you can see, I had two similar problems for Pascal and Icon. In
1503;; Pascal, strings are delimited with ' and an embedded quote is doubled,
1504;; thus string syntax would be extremely simple. However, if a string
1505;; occurs within a comment, the following text is considered a string.
1506;;
1507;; In Icon, strings are similar to C ones, but there are also charsets,
1508;; delimited with simple quotes. I could not manage to use both regexps at
1509;; the same time.
1510
1511;; The problem I have with my patterns for Icon is that this language has a
1512;; string similar constant to the C one (but a string can be cut on several
1513;; lines, if terminated by a dash and continued with initial blanks, like
1514;; this:
1515;; "This is a somewhat long -
1516;; string, written on three -
1517;; successive lines"
1518;; in order to insert a double quote in a string, you have to escape it
1519;; with a \), bu also a character set constant (named a charset), which
1520;; uses single quotes instead of double ones. It would seem intuitive to
1521;; highlight both constants in the same way.

169Headings are lines which start with asterisks: one for major headings,
170two for subheadings, etc. Lines not starting with asterisks are body lines.
171
172Body text or subheadings under a heading can be made temporarily
173invisible, or visible again. Invisible lines are attached to the end
174of the heading, so they move with it, if the line is killed and yanked
175back. A heading with text hidden under it is marked with an ellipsis (...).

177Commands:\\<outline-mode-map>
178\\[outline-next-visible-heading] outline-next-visible-heading move by visible headings
179\\[outline-previous-visible-heading] outline-previous-visible-heading
180\\[outline-forward-same-level] outline-forward-same-level similar but skip subheadings
181\\[outline-backward-same-level] outline-backward-same-level
182\\[outline-up-heading] outline-up-heading move from subheading to heading
183
184\\[hide-body] make all text invisible (not headings).
185\\[show-all] make everything in buffer visible.
186
187The remaining commands are used when point is on a heading line.
188They apply to some of the body or subheadings of that heading.
189\\[hide-subtree] hide-subtree make body and subheadings invisible.
190\\[show-subtree] show-subtree make body and subheadings visible.
191\\[show-children] show-children make direct subheadings visible.
192 No effect on body, or subheadings 2 or more levels down.
193 With arg N, affects subheadings N levels down.
194\\[hide-entry] make immediately following body invisible.
195\\[show-entry] make it visible.
196\\[hide-leaves] make body under heading and under its subheadings invisible.
197 The subheadings remain visible.
198\\[show-branches] make all subheadings at all levels visible.
199
200The variable `outline-regexp' can be changed to control what is a heading.
201A line is a heading if `outline-regexp' matches something at the
202beginning of the line. The longer the match, the deeper the level.

204Turning on outline mode calls the value of `text-mode-hook' and then of

31;; DESCRIPTION:
32;; ------------
33;; This program can be used to monitor running time performance of Emacs Lisp
34;; functions. It takes a list of functions and report the real time spent
35;; inside these functions. (Actually, for each function it reports the amount
36;; of time spent while at least one instance of that function is on the call
37;; stack. So if profiled function FOO calls profiled function BAR, the time
38;; spent inside BAR is credited to both functions.)
39
40;; HOW TO USE:
41;; -----------
42;; Set the variable profile-functions-list to the list of functions
43;; (as symbols) You want to profile. Call M-x profile-functions to set
44;; this list on and start using your program. Note that profile-functions
45;; MUST be called AFTER all the functions in profile-functions-list have
46;; been loaded !! (This call modifies the code of the profiled functions.
47;; Hence if you reload these functions, you need to call profile-functions
48;; again! ).
49;; To display the results do M-x profile-results . For example:
50;;-------------------------------------------------------------------
51;; (setq profile-functions-list '(sokoban-set-mode-line sokoban-load-game
52;; sokoban-move-vertical sokoban-move))
53;; (load "sokoban")
54;; M-x profile-functions
55;; ... I play the sokoban game ..........
56;; M-x profile-results
57;;
58;; Function Time (Seconds.Useconds)
59;; ======== =======================
60;; sokoban-move 0.539088
61;; sokoban-move-vertical 0.410130
62;; sokoban-load-game 0.453235
63;; sokoban-set-mode-line 1.949203
64;;-----------------------------------------------------
65;; To clear all the settings to profile use profile-finish.
66;; To set one function at a time (instead of or in addition to setting the
67;; above list and M-x profile-functions) use M-x profile-a-function.
