Issue #16495 has been updated by mdalessio (Mike Dalessio). It may be interesting to note that the Prism parser has adopted a style guide for error messages, which avoids using the mixed quotes, and uses backticks around token literals to render well in markdown. https://github.com/ruby/prism/blob/main/src/diagnostic.c ---------------------------------------- Feature #16495: Inconsistent quotes in error messages https://bugs.ruby-lang.org/issues/16495#change-105959 * 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/
