Issue #16495 has been updated by mame (Yusuke Endoh). I prototyped it: https://github.com/ruby/ruby/pull/9608 Still need to update prism and ruby/spec. For information in impact assessment: this change made 140 tests fail in `make test-all`. Many of them examined error messages, which could be fixed by simply updating the expected regular expression. But there were some non-trivial effects, e.g., irb converts the error message from `` `top (required)' `` to `` `<main>' ``, so this conversion code is also updated. ---------------------------------------- Feature #16495: Inconsistent quotes in error messages https://bugs.ruby-lang.org/issues/16495#change-106337 * Author: Kolano (Kenneth Kolano) * Status: Open * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- Error messages use inconsistent pairs of quotes, for instance: ``` -e:1:in `<main>': undefined local variable or method `foo' for main:Object (NameError) ``` where a back tick is used on the left-hand side, and a single quote is used on the right. The same quotes should be used on either side of the elements being quoted. -- https://bugs.ruby-lang.org/
