Changes: |
|||
ShowPuzzle gets call only after a word is inserted in the grid. |
|||
Added a check if unixdict.txt was found. |
|||
Made FilePuzzle print to the file. |
|||
If enough words are found but there where still spaces, fill them with random letters. |
|||
FILLED was not set to FALSE every time Initialize was called. |
|||
Set all integer to (U)long. |

![Task](http://static.miraheze.org/rosettacodewiki/thumb/b/ba/Rcode-button-task-crushed.png/64px-Rcode-button-task-crushed.png)
You are encouraged to solve this task according to the task description, using any language you may know.
A word search puzzle typically consists of a grid of letters in which words are hidden.
There are many varieties of word search puzzles. For the task at hand we will use a rectangular grid in which the words may be placed horizontally, vertically, or diagonally. The words may also be spelled backwards.
The words may overlap but are not allowed to zigzag, or wrap around.
- Task
Create a 10 by 10 word search and fill it using words from the unixdict. Use only words that are longer than 2, and contain no non-alphabetic characters.
The cells not used by the hidden words should contain the message: Rosetta Code, read from left to right, top to bottom. These letters should be somewhat evenly distributed over the grid, not clumped together. The message should be in upper case, the hidden words in lower case. All cells should either contain letters from the hidden words or from the message.
Pack a minimum of 25 words into the grid.
Print the resulting grid and the solutions.
- Example
0 1 2 3 4 5 6 7 8 9 0 n a y r y R e l m f 1 y O r e t s g n a g 2 t n e d i S k y h E 3 n o t n c p c w t T 4 a l s u u n T m a x 5 r o k p a r i s h h 6 a A c f p a e a c C 7 u b u t t t O l u n 8 g y h w a D h p m u 9 m i r p E h o g a n parish (3,5)(8,5) gangster (9,1)(2,1) paucity (4,6)(4,0) guaranty (0,8)(0,1) prim (3,9)(0,9) huckster (2,8)(2,1) plasm (7,8)(7,4) fancy (3,6)(7,2) hogan (5,9)(9,9) nolo (1,2)(1,5) under (3,4)(3,0) chatham (8,6)(8,0) ate (4,8)(6,6) nun (9,7)(9,9) butt (1,7)(4,7) hawk (9,5)(6,2) why (3,8)(1,8) ryan (3,0)(0,0) fay (9,0)(7,2) much (8,8)(8,5) tar (5,7)(5,5) elm (6,0)(8,0) max (7,4)(9,4) pup (5,3)(3,5) mph (8,8)(6,8)

Changes: ShowPuzzle gets call only after a word is inserted in the grid. Added a check if unixdict.txt was found. Made FilePuzzle print to the file. If enough words are found but there where still spaces, fill them with random letters. FILLED was not set to FALSE every time Initialize was called. Set all integer to (U)long.

Notes:
While the result is square, we flatten our intermediate results to simplify the code.
dirs
are index offsets within the flattened grid for each of the eight cardinal directions.
lims
is, for each cardinal direction, and for each grid position, how long of a word can fit.
dnms
are names for each of the cardinal directions.
words
are the viable words from unixdict, and fill
is what we're going to leave in the puzzle for spaces not occupied by any of those words (and this could be made into a parameter).
grid
is our working copy of the text of the word search puzzle.
inds
are the indices into grid - we will use these as the starting positions when we place the words.
patience
is a guard variable, to avoid problems with infinite loops if we arbitrarily place words in a non-viable fashion.
key
lists the words we are placing, and where we placed them.
inuse
marks location+directions which already have a word (to prevent short words such as sal from being placed as prefixes of longer words such as sale).
Once we have these, we go into a loop where:
word
is picked arbitrarily from the viable words from unixdict.
dir
is picked arbitrarily from one of our eight cardinal directions.
offs
are places where we might place the word (initially limited only by geometry, but we then constrain this based on what's already been placed).
cool
marks where our word can be placed in unoccupied spaces (and also will be used later to count how many new spaces will be occupied by the word we pick.
sel
marks where our word can be placed such that it does not conflict with existing words.
If this leaves us with any way to place the word, we pick one of them as off
and combine the starting location with dir in loc
to see if a word has already been placed there and if we're good, we place the word and update our key. (It's extremely rare that loc matches an inuse location, so just ignoring that word works just fine).
Otherwise, we check if we're getting impatient (in which case we scrap the entire thing and start over).
Once we're done, we reshape our grid so it's square and attach the key. Here, puz
is the grid formatted for display (with a space between each column, and a numeric key for each row and column).
