Week 3 Day 11

It's Hammertime

We are talking about the Rubygem Thor, of course.

What We Did

Thor is a RubyGem that is used to replace rake, sake, and rubigen. However, that is not how Bundler uses it.

We focused on the Command Line Interface (CLI) aspect of Thor.

Yesterday, we created a new gem by following the now dated RailsCast

Today, we added Thor to our gem to build a command-line interface by reading What is Thor and Building your tools with Thor

For example, we would be creating a command to run our gem like rails new would create a Rails app or running bundle install would install the rubygems you need to run your app.

How to Run Your Unpublished Gem

According to Andre Arko, there are 3 ways to run it.

• ruby -I lib bin/gem_command_name

• bundle exec bin/gem_command_name

• bundle exec gem_command_name

What We Learned from our Boo Boo’s?

Initially, Joyce couldn't get bundle exec bin/gem_command_name to work because the bin/gem_command_name file was missing the shebang #!/usr/bin/env ruby at the very top of the file.

For the last command, we couldn't get bundle excec gem_command_name to work and we don't know why.
