DeepTry

Welcome to deep_try.

I will add a new method to any object, that works like try(:my_method), but with an arbitrary long list of methods.

Add this line to your application's Gemfile:

gem 'deep_try'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install deep_try

With any object use deep_try as follows

    object.deep_try(:class, :name, :to_s) # replace object with your object

This is identical to calling

    object.class.name.to_s

but without failing. If any of the methods return nil or don't exist, then nil is returned as if

    object&.class&.name&.to_s

would have been called.

If you have an array of methods in correct order, let's say

    methods = ["method_1", "method_2", "method_3"]

then use deep_try

    object.deep_try(*methods)

which has the same effect like

    object.method_1&.method_2&.method_3
