Tryout [![Build Status](https://secure.travis-ci.org/endel/tryout.png)](http://travis-ci.org/endel/tryout)

===

Allows you to do dirty stuff without messing up your code base.

Background

---

I've found myself using begin/rescue/retry through HTTP requests frequently, due

timeout, weird stuff caused by a messed up third-party service, or even due

internet connectivity lost.

How to use

---

    value = Tryout.try { RestClient.get('http://www.google.com') }.retry(3)

**if/unless**: call any method on the result of the `try` block.

    value = Tryout.try { RestClient.get('http://www.google.com') }.retry(3, :if => :empty?)

    value = Tryout.try { RestClient.get('http://www.google.com') }.retry(3, :unless => :present?)

**block**: the result of the `try` block will be passed as argument for the second one.

Is up to you when the result is considered invalid.

    value = Tryout.try { RestClient.get('http://www.google.com') }.retry(3) do |invalid|

      # Invalidate when response have length lesser than 100

      invalid.length < 100

    end
