Resolvable
Resolve your successful and failed actions.
Installation
Add this line to your application’s Gemfile:
ruby
gem 'resolvable'
And then execute:
$ bundle
Or install it yourself as:
$ gem install resolvable
Usage
```ruby class SendDelicateMessage include Resolvable
def perform_the_delicate_send! begin perform_the_delicate_send success! rescue => e failure! end end end
delicate_sender = SendDelicateMessage.new delicate_sender.perform_the_delicate_send!
if delicate_sender.success? # yay else # boo end ```
OpenStructShim
Maybe you have a lot of open structs hanging around in your codebase, and you want to start to migrate those:
```ruby class DelicateResult < Resolvable::OpenStructShim; end
begin perform_the_delicate_send return DelicateResult.new(:success? => true) rescue => e return DelicateResult.new(:success? => false, :important_context => “It failed”) end ```
Or maybe you already subclassed OpenStruct in a weird and interesting way, and you want to migrate those, too:
```ruby class Success < Resolvable::OpenStructShim automatic :success! end
class Failure < Resolvable::OpenStructShim automatic :failure! end
begin perform_the_delicate_send return Success.new(:important_context => “It worked”) rescue => e return Failure.new(:important_context => “It failed”) end
``` ## Development
After checking out the repo, run bin/setup
to install dependencies. Then, run rake spec
to run the tests. You can also run bin/console
for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install
. To release a new version, update the version number in version.rb
, and then run bundle exec rake release
, which will create a git tag for the version, push git commits and tags, and push the .gem
file to rubygems.org.
