Ruby Gem Command Line Tool

Question

I am trying to create a ruby gem command line . I use the bundler to create the gem and set the gem in place. He created the necessary directories. I was also able to verify that if I require my Gem, I can use the methods inside it. I am trying to get a part of the command line to work now and cannot seem to make it work. I want to be able to do something like

gemname command

Similar to how rspec works:

rspec test/whatever.rb

Any help on how to execute through the command line would be great.

, , :

• #!/usr/bin/env ruby ( /bin).
• chmod +x filname,
• ARGV[0] ARGV[0]
• s.executables << 'your_file' gemspec

Answer 4

I understood this at least for my specific problem. I just need to call the bin command directly instead of this git ls loop. The top one works for the bottom for no reason.

spec.executables = ["toolshed"]

vs

spec.executables = `git ls-files -- bin/*`.split("\n").map{ |f| File.basename(f) }
