Stan Lo 12b7c129bf [ruby/irb] Gracefully handle missing command argument 
(https://github.com/ruby/irb/pull/473)

* Handle file loading commands' argument error gracefully

Currently, if users don't provide an argument to `source`,
`irb_load`, and `irb_require`, IRB raises `ArgumentError` with full
stacktrace. This is confusing because it looks similar to when IRB has
internal issues. The message also isn't helpful on helping users avoid
the error.

So in this commit, I add a new `CommandArgumentError` for commands to
raise explicitly when users' input doesn't satisfy a command's argument
requirement.

* Gracefully handle `fg` command's argument requirement

What is Ruby?

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

  • Simple Syntax
  • Normal Object-oriented Features (e.g. class, method calls)
  • Advanced Object-oriented Features (e.g. mix-in, singleton-method)
  • Operator Overloading
  • Exception Handling
  • Iterators and Closures
  • Garbage Collection
  • Dynamic Loading of Object Files (on some architectures)
  • Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/maintainers.rdoc#label-Platform+Maintainers

How to get Ruby with Git

For a complete list of ways to install Ruby, including using third-party tools like rvm, see:
