Commonly used Ruby utility functions related to reflection.
| Branch | Status |
|---|---|
| Release |    |

Features
Functions include:
- get_bound_instance_method(instance:, method_name:)
- get_class_constant(instance:)
- call(callback, params = nil)
- has_parameter?(proc, parameter_index, parameter)
- has_parameters?(proc, parameters)
- assert_parameters(proc, parameters)
- non_default_methods(class_or_instance)
- module CreateClassMethodsUponInclude (more: http://lifeinacubicleblog.com/2017/06/26/ruby-how-to-use-self-included-meaningfully)
For usage and examples for each of them take a look at the unit tests.
Another approach would be to include this functionality into classes where its needed. It may be more elegant however moving this functionality into a separate utility class decouples the logic and removes dependency from those classes.
Installation
Add this line to your application's Gemfile:
gem 'reflection_utils'
And then execute:
$ bundle
Or install it yourself as:
$ gem install reflection_utils
Usage
require 'reflection_utils'
# ...

I can only tailor this project to fit use-cases I know about - which are usually my own ones. If you find that this might be the right direction to solve your problem too but you find that it's suboptimal or lacks features don't hesitate to contact me.
