NAME
xtriangles - Triangles X widget
SYNOPSIS
/usr/games/xtriangles [-geometry
[{width}][x{height}][{+-}{xoff}[{+-}{yoff}]]] [-display
[{host}]:[{vs}]] [-{foreground|fg} <color>] [-{back-
ground|bg} <color>] [-{border|bd} <color>] [-tile <color>]
[-{size <int>] [-username {string}]
DESCRIPTION
This is basically no harder than the 15 puzzle. The 15
puzzle was originally made around 1879 (the 14-15 puzzle
of Sam Loyd was made soon after). T. R. Dawson in Origi-
nal Puzzles has a similar puzzle with 4 diamond- and 6
triangular-shaped pieces.
FEATURES
Click "mouse-left" button to move a tile. Clicks on
spaces or clicks tiles that are not in line with the two
spaces will not move the tiles. Notice one can move more
than one tile at a time by clicking on the tile farthest
from the spaces but in line with the spaces.
Click "mouse-right" button, or press "R" or "r" keys, to
randomize the puzzle. One must double click on "mouse-
right" if the puzzle is being worked on.
Press "I" or "i" keys to increase the number of tiles.
Press "D" or "d" keys to decrease the number of tiles.
"S" or "s" keys reserved for the auto-solver (unimple-
mented).
Press "U" or "u" keys to undo move.
Press "G" or "g" keys to get a saved puzzle.
Press "W" or "w" keys to write or save a puzzle.
Press "Q", "q", or "CTRL-C" keys to kill program.
Use the key pad, "R" keys, or arrow keys to move without
the mouse.
Key pad is defined for Triangles as:
7 9 Upper Left, Upper Right
^
4< >6 Left, Right
v
1 3 Bottom Left, Bottom Right
The title is in the following format (non-motif version):
xtriangles: <size> @ (<Number of moves>/{<Record
number of moves> <username>|"NEVER noaccess"}) -
<Comment>
If there is no record of the current puzzle, it displays
"NEVER noaccess".
OPTIONS
-geometry {+|-}X{+|-}Y
This option sets the initial position of the tri-
angles window (resource name "geometry").
-display host:dpy
This option specifies the X server to contact.
-{foreground|fg} color
This option specifies the foreground of the trian-
gles window (resource name "foreground").
-{background|bg} color
This option specifies the background of the trian-

-{border|bd} color
This option specifies the border color of the

derColor").
-tile color
This option specifies the tile color of the trian-

-size <<int>>
This option allows you to change the number of
triangles in a row (resource name "sizeA").
-username string
This option specifies the user name for any
records made or else it will get your login name
(resource name "userName").
SAVE FORMAT
The format is not standard. The reason for this is that
this is simple and I do not know what the standard is.
size: 1-16 <number of tiles in a row of the same
orientation as the puzzle>
moves: 0-MAXINT <total number of moves>
startingPosition: <array of tile positions where 0
is the empty space for the UP triangle and -1 is
the empty space for the DOWN triangle>
This is then followed by the moves, starting from 1.
move #: <direction>
Direction is represented as 0 upper right, 1 right, 2
lower right, 3 lower left, 4 left, and 5 upper left.
Caution: the program may crash on corrupted input.
