Introduce Real-Time Configuration Validation in `pace setup config`

[simonsan]

Overview

While the pace craft setup command has significantly improved the onboarding experience, there's an opportunity to enhance it further by introducing real-time validation for user inputs. This feature aims to ensure that all configuration values provided by users during the setup process are validated on-the-fly, minimizing common configuration errors and streamlining the setup experience.

Objectives

• Enhance User Experience: Provide immediate feedback on configuration inputs to help users correct errors in real-time.
• Reduce Setup Time: Decrease the time users spend on setup by preventing configuration mistakes that require reconfiguration.
• Improve Reliability: Increase the reliability of the pace setup process by ensuring only valid configurations are saved.

Proposed Enhancements

1. Real-Time Input Validation

   • Implement input validation logic that checks user inputs as they are entered during the setup process.
   • Provide immediate feedback to users if the input is invalid, along with helpful error messages or suggestions for correction.
   • Use validator crate

2. Extended Configuration Options

   • Expand the pace setup config command to include prompts for additional configuration values, enhancing customization options for users.
   • Ensure each new configuration option includes specific validation rules based on expected input formats, value ranges, or other criteria.

3. Validation Framework Integration

   • Integrate or develop a validation framework capable of handling various types of inputs and validation rules.
   • Allow for easy extension of the validation framework to support future configuration options.

Request for Comments (RFC)

I invite all contributors, especially those with experience in CLI tools and user input validation, to provide their feedback and suggestions on:

• Best practices for implementing real-time validation in command-line interfaces.
• Ideas for additional configuration options that could benefit from real-time validation.
• Recommendations for existing Rust crates or libraries that facilitate input validation and error handling.

Conclusion

By introducing real-time validation for configuration inputs in the pace setup config command, we aim to make the onboarding process even smoother and more user-friendly. This enhancement will not only save users time by preventing common mistakes but also strengthen the overall reliability of the pace configuration process.
