instead use tuidoku instead.

Simple ncurses program to play sudoku in the terminal written entirely in C++

Fill in all the missing squares with no repeating digits in the column, row or box. Use hjkl, wasd or arrow keys to navigate around the board. Press i or p to enter input mode or pencil mode respectively. You can also toggle between the two modes by pressing escape. To go to a specific box on the board type g followed by the column number then the row number. For example, to go to column 4, row 2 type g42. Press c to check the puzzle for any wrong inputs, mistakes turn red and correct inputs turn blue. Press c again to remove the colors. This game supports up to 3 pencil marks per box. To remove a mistake or the most recent pencil mark press your spacebar in their respective modes. To remove a specific pencil mark enter that number in the box when in pencil mode.

You can pass the max number of empty boxes in the generated board by passing any integer greater than 0 as an argument.
To change the text on the right from hjkl to wasd pass the argument -w or --wasd.
This program is able to parse opensudoku and sdm files for puzzles. Pass --opensudoku or --sdm followed by the filename to parse the file.

clone this repository then compile using g++ or clang++

git clone https://github.com/flyingpeakock/Console_sudoku.git
cd Console_sudoku/
g++ -O3 -pthread ./src/*.cpp -lncursesw -o console_sudoku

git clone https://github.com/flyingpeakock/Console_sudoku.git
cd Console_sudoku/
clang++ -O3 -pthread -std=c++11 -stdlib=libc++ ./src/*.cpp -lncursesw -o console_sudoku

This program is also located on the arch user repository.

yay -S console_sudoku

-lncursesw flag is required to link ncurses.h
-O3 is recommended to speed up puzzle generation but is not required.

To run this program from any directory move the generated console_sudoku file to anywhere in your $PATH.

cp console_sudoku ~/.local/bin/console_sudoku

If the compiler cannot find ncurses.h you need to make sure that ncurses is installed. If you cannot find ncurses in your package manager it might be called something like libcurses or curses instead. If it still doesn't work use the -lncurses flag instead of -lncursesw when compiling.

You can use the Generator files and Solver files to generate or solve sudoku puzzles, some C++ experience is recommended but not required if you don't mind learning a little.

To solve an unsolved puzzle create a Solver object and pass the unsolved puzzle to the constructor. The unsolved puzzle can be an int**, int[9][9] or a 9x9 std::array. Solve the puzzle by calling the solve method on the Solver object. To get the solved puzzle call the getGrid method on the object, this method returns a 9x9 std::array. To check if the supplied puzzle generates a unique solution the method isUnique may be called, this returns a boolean.

The generator uses Solver to build and check uniqueness of puzzles, To create a puzzle create a Generator object. To get the unsolved puzzle call the method getGrid. To get the solved puzzle call the method getSolution.
