ExceptionUtilities

Utilities for handling exceptions.

Installation

Add this line to your application's Gemfile:

gem 'exception_utilities'

And then execute:

$ bundle

Or install it yourself as:

$ gem install exception_utilities

Usage

Ignoring specific exceptions

Use exceptions_ignoring_eval:

require 'exception_utilities/kernel'

exceptions_ignoring_eval(LoadError) do
  require 'foo'
end

Rescue exceptions having specific message

Use exceptions_with_message:

require 'exception_utilities/kernel'

begin
  SomeModel.create!
rescue exceptions_with_message(/\Bfoo_bar_id\B/, ActiveRecord::RecordNotFound)
  Rails.logger.debug([$!.message, *$!.backtrace].join("\n"))
end

Creating exception matcher

Use exception_matcher:

require 'exception_utilities/kernel'

begin
  # some routine
rescue exception_matcher {|exc| exc.count <=1 }
  # ignore
rescue exception_matcher {|exc| exc.count > 1 }
  raise
end
