Garns

A simple Sudoku-solver named after Howard Garns, the creator of Number Place which became later known as Sudoku. You can provide it an input file containing the starting position of a Sudoku puzzle. By default, garns outputs the solution into stdout.

Getting started

To get started, build the project.

go build -o garns main.go

Solving puzzles

The command-line interface takes a file containing the puzzle as input. The puzzle must be nine lines of nine character. Each known number in the puzzle must be given as is in the input. Each unknown place can be either a dot (.) or a zero (0).

To solve a puzzle from an input file, run the solve command and the --file options to specify the input file.

garns solve -f path/to/input.txt
