A terminal-based Sudoku game built with ncurses, featuring interactive play and PDF/PNG export.
nudoku is a Sudoku game designed for the terminal, built using the ncurses library. It allows users to play Sudoku interactively with a keyboard-driven interface and can export puzzles to PDF or PNG formats for offline use. The project solves the need for a lightweight, command-line-based puzzle game that doesn't require a graphical desktop environment.
Terminal users, Linux/Unix enthusiasts, and developers who enjoy command-line applications or want a distraction-free puzzle game. It's also suitable for those needing to generate Sudoku puzzles for printing or sharing.
Developers choose nudoku for its minimal dependencies, efficient ncurses interface, and flexibility in puzzle generation and export. It stands out as a straightforward, open-source alternative to graphical Sudoku games, with the added benefit of scriptable output options.

Uses ncurses for a full interactive GUI in the terminal, enabling keyboard-driven gameplay without graphical dependencies, as shown in the README's installation and usage.
Supports exporting puzzles to PDF or PNG formats via optional Cairo integration, with commands like `nudoku -p riddle.pdf` for batch generation, detailed in the usage section.
Includes gettext-based translations with community contributions, managed through the `po/LINGUAS` file and LANGUAGE environment variable, as explained in the I18n section.
Can be compiled with debug output using `-DDEBUG` flag, aiding development and troubleshooting, as mentioned in the install instructions.
Export features require Cairo, adding an extra dependency and configuration step like `./configure --enable-cairo`, which complicates setup for casual users.
Reliant on ncurses, so it lacks graphical enhancements and cannot be used outside terminal environments, limiting appeal for modern UI seekers.
Installing from source involves steps like autoreconf and configure, as per the README, which may be less convenient than one-click installers for non-developers.
