Creating a Digital Garden CLI with Rust by Chris Biscardi

• README-driven planning for a Digital Garden CLI in Rust
• Initialize a new Cargo binary crate in a new package
• Rename the default Cargo binary to be different than the package name
• Using the todo macro to typecheck unwritten code that will be implemented in the future
• Using color_eyre and distributed tracing to yield better error messages to the user
• Setting up git-like subcommands using structopt
• Documenting and writing helptext for Structopt CLI commands and flags
• Integration testing Cargo binaries with assert_cmd
• Matching structopt commands and using Rust values after move
• Creating a library crate to support a Rust binary crate in the same package
• Adding support for global flags that apply for all subcommands with structopt
• Passing control to the user's favorite editor (such as VSCode) from the CLI
• Using the Option type in Rust to pick from multiple values that might not exist
• Prompting the user for input with rprompt and loop
• Checking for file existence with PathBuf to ensure unique filenames
• Using owo_colors Extension Traits to colorize terminal output
• Using assert_fs and predicates to integration test with a real temporary file system
• Abstracting test utilities inside integration test files
