A Common .ruby-version File For Ruby Projects

A Common .ruby-version File For Ruby Projects

Background

I've been using this technique in most of my Ruby projects lately where Ruby versions are required:

  • Create .rbenv-version containing the target Ruby using a definition name defined in ruby-build (example below). These strings are a proper subset of RVM Ruby string names so far...
  • Create .rvmrc (with rvm --create --rvmrc "1.9.3@myapp") and edit the environment_id= line to fetch the Ruby version from .rbenv-version (example below).

Today I learned about another Ruby manager, rbfu, where the author is using a similar technique with .rbfu-version.

capybara date select step definition for cucumber
# capybara step definition for a quick and dirty date select
# For example:
# When I select "May 7, 2010" as the post "published_on" date
When /^I select "([^"]*)" as the (.+) "([^"]*)" date$/ do |date, model, selector|
date = Date.parse(date)
select(date.year.to_s, :from => "#{model}[#{selector}(1i)]")
select(date.strftime("%B"), :from => "#{model}[#{selector}(2i)]")
select(date.day.to_s, :from => "#{model}[#{selector}(3i)]")
end
