HasseGameLib is (currently) a one-man project of making a library for making programming CLI-Games a little bit easier. It has some functions for drawing to the CLI, making savefiles and reading them and it also has a keylistener. It is currently linux-only, I'm planning on making a windows version.
ConsoleFx is an .NET framework for easily developing command-line interface (CLI) applications. It automates most of the work involved in creating a CLI application, like command line argument parsing, error handling and validations. ConsoleFx supports both fluent and declarative (using attributes) programming models.
With ConsoleFx, you can say goodbye to lengthy cumbersome code to parse your command-line arguments.
