sbg - StructOpt-driven Boilerplate Generator

You give this a yaml spec and it generates boilerplate code for you, which compiles if you give it Cargo.toml with these contents:

toml [dependencies] pretty_env_logger = "0.2" serde_derive = "1" structopt = "0.2" log = "0.4"

I am aware that there is a macro to do this (in clap), but what the heck! Also, this is not flexible, and only supports a tiny subset of what structopt/clap supports.

The first time [steved] mentioned the idea to me, I felt "meh!", but once you get to nested subcommands, it becomes unwieldy the code you gotta write to handle that. He even went as far as writing the code (not public), but unsatisfied by the notation, I wrote this implementation. My actual inspiration though is I wanted something that'd also generate [warp] boilerplate, together with the [reqwest] code which generates it (which also exists, but is also not public).

Would be nice to fix

• check "type" actually has valid Rust types
• check "name" does not have spaces
• disallow having both "args" and "nested" (results in build failure), or support it (which would be useful for subcommands that share some options)
• when "type" is not specified, assume bool
• ensure no args have same name (results in build failure)
• support > 1 positional args

Installation

Assuming you have the Rust toolchain installed):

cargo install sbg
