harness

Warning: This tool is a work in progress. It has severe limitations. I'm working on this project in conjunction with another, extracting pieces of functionality that can belong in this package, able to be reused.

Quickly helps setup an opinionated CLI harness.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     harness:
       github: Willamin/harness
   

2. Run shards install

Usage

require "harness"

class MyApp::Cli < Harness::Cli
  @[Harness::Subcommand]
  def version
    STDOUT.puts("myapp 1.0.0")
  end
end

Create a subclass of the type Harness::Cli. This will get you setup with a harness for subcommand-style CLIs. To add a subcommand, write a method with the name of the subcommand and add the annotation @[Harness::Subcommand]. This tells the harness to listen for this subcommand.
