History
-------

MyMan was written on a dare on Sunday, 1998-06-28. The original
version had no color or attribute support and only supported large
tiles (equivalent to -z big.) It was 742 lines of ANSI C and used
three data files: a maze file (equivalent to -v pac), a tile file and
a sprite file. It worked with ncurses on Linux and cygwin. Several
variations using other maze layouts were created over the following
hours. Color came in December of that year, as did support for small
tiles (equivalent to -z small.) The mygetopt argument parser is a bit
older, having been started in 1997 as part of the SMOKE-16 project.


Acknowledgements
----------------

Toru Iwatani had the original idea for Namco's 'Pac-Man'/'Puck-Man',
which in turn served as inspiration for this game.
Innumerable others have written their own variants of the original
game which in turn inspired variants for this game, and I have tried
to credit them where authorship is known. Credits for each variant are
listed in the in-game help screen reachable by pressing ? or Ctrl-H.


Description
-----------

Basic premise of the MyMan video game:

  "Those scary ghosts are back, and this time they've spotted
   you! What's worse is that they've mistaken you for their old
   rival Pac, and they're out for (yellow) blood!"

MyMan displays (A) on a text terminal or terminal emulator (using
ncurses, slang, PDCurses, SysV curses, BSD curses, old VMS curses, or
the raw stdio terminal driver), (B) on an X Window System display
(using PDCurses for X, a.k.a. XCurses), (C) on any terminal or display
supported by PDCurses for SDL, libcaca, LibGGI/LibGII, Allegro, TWin,
aalib, Carbon/Toolbox, newt, GTK+, FLTK, <disp.h>, Borland-style
CONIO, or the Extensible Firmware Interface (EFI) or (D) in a Win32
command prompt window (using the raw Win32 terminal driver).  Since
MyMan is fairly fast-moving, you'll need a reasonably fast computer
and display.  It once ran acceptably fast on a 486-66 under Linux, and
may still.

Installation
------------

Installation instructions are in the file INSTALL.


License and Version
-------------------

The MyMan version number is recorded in the file VERSION inside the
source package. To determine the version number of an installed MyMan
executable, run e.g. 'myman -V'.

This version of MyMan has a BSD-like license; see the file LICENSE for
details. Earlier versions were placed in the public domain.

MyMan includes a bundled copy of the 'mygetopt' argument parser,
which is licensed under the same terms as MyMan; see the README file
in the 'mygetopt' subdirectory of the MyMan source distribution
for details.

Note that the contents of the MyMan datafiles (tiles, sprites and
mazes) are in the public domain.

The file 'start.xm' is by Raina / Titan and was originally created in
2007 for an AmigaOS 4.0 port of MyMan 0.6. See:

http://os4depot.net/index.php?function=showfile&file=game/action/pfp-myma.lha


To Do
-----

See TODO for notes on desired features and bugfixes.


A Note on Text Encoding and the B.O.M.
--------------------------------------

Note that many files in the MyMan distribution are distributed as
Unicode/UCS text in the UTF-8 encoding with an explicit "byte-order
mark" (B.O.M.) at the beginning. This three-byte sequence (0xEF, 0xBB,
0xBF in hexadecimal notation) allows many web browsers and text
editors on Windows, Mac OS X, and other operating systems to
automatically select the correct character encoding when displaying or
editing the files. Please try to preserve this sequence when further
redistributing the files or sending in patches so that others will be
able to read the files painlessly.


Environment Variables
---------------------

Some configurations of MyMan are influenced by the values of
environment variables, in addition to those behaviors documented for
the underlying display libraries:

Detailed Notes
--------------

For basic usage information, refer to the text version of the MyMan
manual page, myman.txt (generated from myman.man by 'make docs' using
groff.)


A. When Power Pellets Look Strange:

The compile-time option -DSWAPDOTS=1 or the equivalent command-line
option '-o' or in-game command 'O' or '0' is often necessary for a
decent display. This depends greatly on what font you use.


B. More Authentic Colors:

If you have a color X server and the XFree XTerm terminal emulator,
you can try the included xmyman script which should start MyMan in a
window of its own, with proper colors. If you have the rxvt terminal
emulator, you can try the xmyman2 script for a similar effect. And
finally, if you have XFree86 XTerm and a font for IBM codepage 437,
you can try the included xmyman3 script for more different types of
pseudo-graphic characters (single and double lines, dots, and power
pellets.)

Alternatively, you can get the "ctheme" package from

   http://sourceforge.net/project/?group_id=2640

and then run the included 'myman.ct' color theme script in your XTerm
or on the Linux console.

Changing your terminal's palette can greatly improve the experience;
recommended RGB values for each palette entry are listed at the end of
this file.

If you're using the Mac OS X Terminal application, you may install
TerminalColors to get customizable colors:

   http://www.culater.net/software/TerminalColors/TerminalColors.php

The myman.term file in the MyMan distribution takes advantage of
TerminalColors (if installed) to set the MyMan color palette.

If you're using the Darwin/Mac OS X console (this is a "text mode"
with no GUI or windowing system and is very rarely used,) you may
install utl/mach_mypal to switch your console to an appropriate
palette and utl/mach_acs to enable alternate character set (line
drawing) support. These have only been tested in Mac OS X 10.4 "Tiger"
so far.


C. Window Size:

A terminal height of 34 or more lines works quite nicely, but 24 or 25
(or even less) will work. Similarly, a width of 58 or more characters
is nice, but not required. If you're a real pro (or lacking screen
real-estate) you can play MyMan in a terminal window with 7 lines of
12 characters each... it's actually playable!


D. Keyboard Map:

       The following case-insensitive keystroke commands are recognized during
       the game:

       Q or Ctrl-C:
              quit the game

       P or ESC:
              pause the game

       Ctrl-Q:
              re-enable output (after Ctrl-S)

       R, Ctrl-L or Ctrl-R:
              refresh (redraw) the screen

       @:     reset the display subsystem and refresh (redraw) the screen

       Ctrl-S:
              inhibit output until Ctrl-Q is typed

       S:     toggle sound on/off

       W:     warp to the next level (after consuming the next dot)

       C:     toggle color on/off (if enabled at compile-time)

       B:     toggle use of dim and bold attributes for missing colors

       U:     toggle underlining of walls on/off (if enabled at compile-time)

       D:     toggle maze debugging on/off

       T:     save an HTML screenshot to the file snap####.html, where #### is
              a four-digit sequence number, and flash the screen briefly; a
              plain text version is saved as snap####.txt using backspacing
              to represent underlined and bold text

       O or 0:
              toggle appearance of power pellets and dots

       A:     toggle between ASCII altcharset translations and your terminal's
              altcharset translations

       I:     toggle between using your terminal's vertical scrolling capabil-
              ities and redrawing the screen

       X:     toggle between raw tile characters (CP437 or UCS/Unicode charac-
              ter graphics) and altcharset translations (VT100-style graphics)

       E:     toggle between UCS/Unicode and CP437 for internal representation
              of raw tile characters

       H, 4, Ctrl-B or LEFT:
              move left

       J, 2, Ctrl-N or DOWN:
              move down

       K, 8, Ctrl-P or UP:
              move up

       L, 6, Ctrl-F or RIGHT:
              move right

       , (comma) or <:
              cancel pending vertical move

       . (full stop) or >:
              cancel pending horizontal move

       / or \:
              toggle diagonal maze reflection

       !:     display information about the maze, tileset and
              spriteset

       ? or Ctrl-H:
              display help screen

       The pager recognizes the following special commands:

       SPACE:
              display next page or finish

       ESC:   finish immediately

       Move left then right with no intervening keystrokes:
              equivalent to ESC

E. Configuration at Start-Up:

Several of the game's settings can be changed at startup using
command-line parameters; use the '-h' parameter for more information.


F. Configuration at Compile-Time:

There are several properties of the game which may be altered using
compile-time options:

Compile-time option           Default value         Description
MYMANDELAY                    25000                 Delay is between updates.
                                                    (in microseconds)
SPEEDUP                       1000                  Amount delay decreases
                                                    after each level.

Values other than the default and 0 don't work particularly well. This
uses the usleep library function.

Boolean Compile-time option   Default value         Description
USE_ATTR                      (automatic)           Try to use attributes.
USE_COLOR                     (automatic)           Enable color support.
USE_PALETTE                   1 (except under       Enable support for
                                 slang)             color palette manipulation.
USE_KEYPAD                    (automatic)           Try to use the keypad.
USE_ACS                       1                     Use your terminal's
                                                    altcharset translations by
                                                    default.
USE_RAW                       0                     Output untranslated CP437
                                                    character graphics by
                                                    default.

The preceding options affect which curses features MyMan uses. MyMan
was developed using ncurses, primarily under GNU/Linux. It should be
fairly portable to other operating systems and other SysV-like curses
implementations. A partial port to old BSD curses has been completed,
and uses the FIONREAD ioctl to simulate nodelay(). A port to old VMS
curses has also been completed bypassing getch() and using raw QIO.

Options with automatic default values will be enabled if your curses
implementation seems to support them. Support is verified by checking
for relevant #defines; if your curses implementation doesn't provide
the relevant #defines, the default value will likely be wrong. This
guessing process is pessimistic, meaning that features are more likely
to be erroneously disabled than erroneously enabled.

Boolean Compile-time option   Default               Description
SWAPDOTS                      0                     Use 'o' for power pellets
                                                    and ACS_BULLET for dots.
                                                    (useful for vt100/latin-1
                                                     terminals and emulations)

This compile-time option can be modified on the command-line or at run-time.

Boolean Compile-time option   Default               Description
COLORIZE                      1                     Try to use color.
                                                    (somewhat slower than
                                                     monochrome)

This compile-time option can be modified on the command-line, and
toggled at run-time using 'c', provided USE_COLOR is non-zero.

Compile-time option           Default value       Description
TILEFILE                      "chr/chr5x2.txt"    File containing maze tiles.

A tile file contains a dimension specifier followed by some tiles. The
dimension specifier is of the form WxH, where W and H are decimal
integers corresponding to the width and height of the tiles. This may
optionally be followed by ~F, where F is a flag bitmap written as a
decimal integer. The flag bits defined so far are "2", which indicates
invertable bitmap tiles, and "4", which indicates that all
non-inverted wall parts should have their background color set. The
line may optionally end with tile file arguments ' arg1=value1
arg2=value2 ...'.

Tile Argument           Description
ABOUT                   Textual description of this tile file
NOTE                    Additional notes for this tile file
FIXME                   Known problems with this tile file

Each maze tile is described as follows:
XX~Y <- two-digit hex code; corresponds roughly to CP437 character code.
   ^___ optional: '~' followed by 1-digit hex code; corresponds to color.
:cccc...cc <- ':' followed by W characters; further characters ignored.
(repeated H times)
Blank lines are ignored.

Hex codes with special meaning:

20(' '),FF: walkable tile
2E('.'),F9: edible dot
6F('o'),FE: power pellet
3D('='),3A(':'),F0,FF: door (to ghost house)
7E('~'): secret door in horizontal wall
6C('l'): secret door in vertical wall
3C('<'),AE: zap left to matching right zap
3E('>'),AF: zap right to matching left zap
76('v'): zap down to matching up zap
5E('^'): zap up to matching down zap
10,11,18-1B,1E,1F,2B('+'),2D('-'),7C('|'),B3-DA,F0: walls

Compile-time option       Default value          Description
SPRITEFILE                "spr/spr7x3.txt"       File containing sprites.

A sprite file contains a dimension specifier followed by some
frames. The dimension specifier is of the form WxH, where W and H are
decimal integers corresponding to the width and height of sprite
frames.  This may optionally be followed by ~F, where F is a flag
bitmap written as a decimal integer. The only flag bit currently
defined is "1", which indicates that ghost eyes are invisible. The
line may optionally end with sprite file arguments ' arg1=value1
arg2=value2 ...'.

Note that ghost eyes are always visible while a ghost is returning
home (after being eaten.) Setting the "1" flag bit is a good idea if
your ghost eye sprite totally obsures your "mean" ghost sprite.

The sprite frame format is similar to the maze tile format, with the
following differences: a literal NUL (ASCII 0) in the description is
treated as a transparent character, and the hex codes are as follows:

00-07: level indicators (fruit, keys, etc.)
08-09: "mean" ghost body animation
0a: ghost eyes looking up
0b: ghost eyes looking left
0c: ghost eyes looking down
0d: ghost eyes looking right
0e-0f: "scared" ghost animation
10-13: MyMan walking up animation
14-17: MyMan walking left animation
18-1b: MyMan dying animation

Compile-time option           Default value         Description
MAZEFILE                      "lvl/maze.txt"        Maze description file.

The maze description file starts with a line containing 'N WxH' or 'N
WxH~F' and optional maze arguments ' arg1=value1 arg2=value2 ...', and
the remaining lines are an ASCII picture of the maze. If present, F is
a flag bitmap written as a decimal integer. The flag bits defined so
far are "1", which indicates that maze changes only occur at game
intermissions, "2", which indicates whether to repeat the FLIP_TO maze
after showing the last maze, and "4", which indicates that wall color
choice should be based on wall thickness, rather than whether a wall
edge or a filled wall section is being drawn.

NOTE: The Python program scripts/asc2txt.py can be used to
      automatically convert plain-ASCII ".asc" mazes to UTF-8 ".txt"
      mazes. The output of scripts/asc2txt.py often needs some manual
      cleanup.
