What is the difference between the bundle & bundler commands?
What is the difference between bundle &
The executables bundle & bundler have the same functionality and therefore can be used interchangeably. You can see in the bundler/exe directory that the bundler executable just loads the bundle executable. It seems to me that the bundle command is more commonly used than the bundler command.
The commands bundle & bundle install also have the same functionality. bundle uses Thor, and bundle's default task is install. Also, bundle i does the same thing as bundle install because bundle's task i is mapped (aliased) to install.
That's a GREAT question. :-) Ruby tends to follow the Perl programming motto: "There's more than one way to do it." I tend to prefer the Zen of Python principle: "There should be one—and preferably only one—obvious way to do it." I think the latter principle caters to the principle of least astonishment and tends to help keep things simple. Overall however, I still tend to prefer to program in Ruby (especially when building HTTP-based RESTful APIs, for which I use Rack). I think Ruby is simple, elegant, and readable. Perhaps Ruby would be even better if it took on Python's stance regarding this issue.
