Crate Clap

Setup Steps 🔗

An example of project where this was used is zola_chrono but I want to stop including the logging level as part of it and defer to using environment variables as already supported by env_logger.

• Add dependency

  cargo add clap -F derive,cargo,wrap_help
  

• Copy cli.rs and add and remove as needed
• Copy from main.rs as needed
• Testing

  #[cfg(test)]
  mod tests {
  
      #[test]
      fn verify_cli() {
          // Source: https://docs.rs/clap/latest/clap/_derive/_tutorial/index.html#testing
          // My understanding it reports most development errors without additional effort
          use clap::CommandFactory;
          super::Cli::command().debug_assert()
      }
  }
