Call a rubygem's binary executable from inside my rails applications?

问题

I know that bundler makes a gems executables available using the bundle exec command. I want to understand how I can call these executables from inside a controller action or model class method? I don't see anything about this in the Bundler doco.

回答1:

Executables are ruby scripts sitting in the bin directory of the gems and their behavior depend on each gem. They are wrappers around the gems classes/APIs: simply dig into the source code of the gems you target and mimic the behavior of their CLIs.
