Ruby – How to tell bundler where the Gemfile is

bundlerruby

I'm trying to run a Ruby script from cron.

The script uses Bundler to manage gem dependencies. Since cron does not run in $PWD I get a 'Could not locate Gemfile' error from Bundler everytime, which makes sense since Gemfile is not in the currrent path when running from cron.

Is there a way to tell Bundler to use a Gemfile not in the current path?

The best thing to do would be to cd into the directory in question in your cron. You could also use the BUNDLE_GEMFILE environment variable to point at the Gemfile. Please let us know if you have any problems with BUNDLE_GEMFILE.

Ruby – How to write a switch statement in Ruby

Ruby uses the case expression instead.

case x
when 1..5
  "It's between 1 and 5"
when 6
  "It's 6"
when "foo", "bar"
  "It's either foo or bar"
when String
  "You passed a string"
else
  "You gave me #{x} -- I have no idea what to do with that."
end

Ruby compares the object in the when clause with the object in the case clause using the === operator. For example, 1..5 === x, and not x === 1..5.

This allows for sophisticated when clauses as seen above. Ranges, classes and all sorts of things can be tested for rather than just equality.

Unlike switch statements in many other languages, Ruby’s case does not have fall-through, so there is no need to end each when with a break. You can also specify multiple matches in a single when clause like when "foo", "bar".
