Issue #16495 has been updated by mame (Yusuke Endoh). Let me add a little to the matz's decision. At the dev meeting, he said that we will replace with a single quote, not only the backticks for `NameError#message`, but also the ones for other exception messages (e.g., ``no superclass method `foo'``) and the ones surrounding the names of methods in the backtrace (e.g., ``from test.rb:2:in `foo'``). Matz also wants to experiment with #19117 as well, and I am writing an experimental patch for that. If this is also applied, each line of the backtrace will be ``` before: from test.rb:9:in `foo' after : from test.rb:9:in `Kernel#p' ``` We recognize that both this ticket and #19117 are not small incompatibilities, so if they actually change, it would be nice to change them both at once. ---------------------------------------- Feature #16495: Inconsistent quotes in error messages https://bugs.ruby-lang.org/issues/16495#change-106334 * 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/
