Status changed from Open to Closed Fixed by commit:2bde7919a0a8302c344e9bb9ddc217958fcbd3c7 ---------------------------------------- Bug #16506: Documentation for `Module#const_souce_location` is wrong https://bugs.ruby-lang.org/issues/16506#change-84042 * Author: sawa (Tsuyoshi Sawada) * Status: Closed * Priority: Normal * Assignee: * Target version: * ruby -v: 2.7 * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN ---------------------------------------- https://ruby-doc.org/core-2.7.0/Module.html#method-i-const_source_location says: > Returns the Ruby source filename and line number containing **first** definition of constant specified. It should be: > Returns the Ruby source filename and line number containing the **last** definition (the effective definition) of the constant specified. It also has an example line: ```ruby p Object.const_source_location('A') # => ["test.rb", 1] -- note it is first entry, not "continuation" ``` but that may give the impression that the first-ness is due to the nature of this method. The reason `["test.rb", 1]` is returned instead of `["test.rb", 14]` is because the constant is created at line 1, and is only reopened/modified in line 14. Perhaps, this line can be changed to: ```ruby p Object.const_source_location('A') # => ["test.rb", 1] -- note 'A' is created in line 1, and is only reopened/modified in "continuation" ``` Adding something like this may make it clear that it is the last definition that is returned: ```ruby D = 'D1' D = 'D2' D = 'D3' ... Object.const_source_location('D') # => returns the location that corresponds to 'D3' -- https://bugs.ruby-lang.org/ Unsubscribe:
