This is a fun project which I have mainly used to teach myself Go programming.
The puzzle files in the data folder are from: https://github.com/mikix/nonogram-db
Each puzzle file is a YAML file which contains the puzzle definition. The required format should be clear from an examination of any one of the puzzle files in the data directory.
Compile the code, and then run the executable, pointing it to a puzzle file. See the data directory for examples.
nonogo --puzzle=./data/burning.nonogram.yaml --debug=true|false
