cling

[ALPHA] cling is a Rust framework that simplifies building command-line programs using clap.rs.

High-level direction

• Support both async and sync Rust command-line applications and don't tie to specific async runtime.
• Promote specific design patterns with limited escape hatches.
• Creates CLIs that follow design best practices by default:
  • Support for configuration
  • Logging
  • Unit testable commands
  • Propagates errors to main with sane default printer
  • Translates Result::Err to non-zero exit codes
  • Support for building REPLs
  • Do we want to support non-derive clap as well? No!
