# 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:
```python
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")
```
