CLI
A small command line interface library for quickly building cli apps.
Usage
Add this to your Gemfile:
gem 'avalanche-cli', :git => 'git://github.com/avalanche123/cli.git'
Build a single command script:
#!/usr/bin/env ruby
require 'bundler/setup'
require 'avalanche/cli'
cmd = Avalanche::CLI::Command.new('hello [options] NAME', {
:title => ['--title TITLE', String, 'Desired title']
}, Proc.new do |opts, args|
raise "NAME is required" if args.empty?
puts "Hello, #{opts[:title]} #{args.first}!".gsub(/\s+/, " ")
end)
cmd.run(ARGV)Build a cli application with many subcommands:
#!/usr/bin/env ruby
require 'bundler/setup'
require 'avalanche/cli'
app = Avalanche::CLI::Application.new('app', '0.1.0')
app.command('hello [options] NAME', "Says Hello", {
:title => ['--title TITLE', String, 'Desired title']
}, Proc.new do |opts, args|
raise "NAME is required" if args.empty?
puts "Hello, #{opts[:title]} #{args.first}!".gsub(/\s+/, " ")
end)
app.run(ARGV)Check it:
