Method: Im::Loader::Config#on_load

Defined in:
lib/im/loader/config.rb

#on_load(cpath = :ANY, &block) ⇒ Object

Configure a block to be invoked once a certain constant path is loaded. Supports multiple callbacks, and if there are many, they are executed in the order in which they were defined.

loader.on_load("SomeApiClient") do |klass, _abspath|
  klass.endpoint = "https://api.dev"
end

Can also be configured for any constant loaded:

loader.on_load do |cpath, value, abspath|
  # ...
end

Raises:

  • (TypeError)
