CLI Rack

Lightweight set of tools for creating pretty-looking CLI applications in Python. This library tends to simplify and unify the approach to structuring CLI related code. At the moment it covers:

• Managing terminal output - verbosity levels, colored output, logger configuration
• Parsing arguments
• Modular application design - each module could extend argument parser with own command
• Modules discovery - scanning packages to find cli extension modules
• Module availability support - module might declare a method to verify if environment is suitable (e.g. all dependencies are present). If not, module will be automatically excluded from CLI interface
• Sync and Async execution manager

More details and documentation is here: https://github.com/corvis/cli-rack

Quick examples

Using unified CLI output:

from cli_rack import CLI

CLI.setup()

CLI.print_info("This is just a message to user")
CLI.print_warn("This is a warning")
CLI.print_error("This is an error message")
CLI.print_error(ValueError("This is an exception"))
CLI.print_data("This text comes to STDOUT, not STDERR")
