Read the documentation https://ruby-doc.org/core-2.7.0/Module.html#method-i-autoload: >autoload(module, filename) ��� nilclick to toggle source Registers filename to be loaded (using Kernel::require) the first time that module (which may be a String or a symbol) is accessed in the namespace of mod. Your `foo.rb:1` registers the file to be read when a potential constant named `:Bar` is met. Your `foo.rb:3` calls a constant `Bar` for the first time, at which point the file `./bar` is read and `Bar` is defined. ---------------------------------------- Bug #16764: Module.const_source_location does not work on autoloaded constants https://bugs.ruby-lang.org/issues/16764#change-84947 * Author: exterm (Philip M��ller) * Status: Open * Priority: Normal * ruby -v: ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin19] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN ---------------------------------------- As we found when trying out `const_source_location` on a Rails project, it breaks when used on autoloaded constants. Example: ``` $ cat foo.rb autoload :Bar, './bar' Bar puts Module.const_source_location("Bar") ``` Returns `foo.rb:3`, when it should return `bar.rb:1`. -- https://bugs.ruby-lang.org/ Unsubscribe:
