Sudoku

Simple sudoku for the terminal using ncurses and written in C.

Building

Simply run:

git clone https://github.com/8dcc/sudoku
cd sudoku

# For the game itself
make sudoku.out

# From a simple text solver
make solver.out

# Or both at once
make

If you don't want the game to show colors (for ncurses) simply comment this line in src/game/globals.h.

If you don't want the solver program to show colors (for example for some windows terminals or for redirecting the output) simply comment this line in src/solver/defines.h.

/*
 * Comment this line if you don't want colors!
 * Will not print with colors if not defined, useful for redirecting the output of
 * the command.
 */
#define USE_COLOR

Playing the game

Simply run:

$ ./sudoku.out --help
Usage:
    ./sudoku.out            - Run with default difficulty.
    ./sudoku.out <number>   - Where number is the number of cells that are going to be filled. [1-80]

Using the solver

The solver program will try to read from the filename specified as argument, or stdin if none. The program checks if stdin is a piped file or command output (only on linux) and prints the usage if not.

$ ./solver.out filename.txt
...

$ ./solver.out < filename.txt
...

$ cat filename.txt | ./solver.out
...

$ ./solver.out      # Will only check for pipes on linux
Usage:
    ./solver.out file.txt
    ./solver.out < file.txt
