From: "nobu (Nobuyoshi Nakada) via ruby-core" Date: 2023-07-26T23:32:53+00:00 Subject: [ruby-core:114299] [Ruby master Bug#19786] Data::define() does not work as documented Issue #19786 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Closed Backport changed from 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN to 3.0: DONTNEED, 3.1: DONTNEED, 3.2: REQUIRED It was fixed at commit:cada537040743cbe49aac6740816d648ca0d3fb6. To be backported. ---------------------------------------- Bug #19786: Data::define() does not work as documented https://bugs.ruby-lang.org/issues/19786#change-103997 * Author: thyresias (Thierry Lambert) * Status: Closed * Priority: Normal * ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x64-mingw-ucrt] * Backport: 3.0: DONTNEED, 3.1: DONTNEED, 3.2: REQUIRED ---------------------------------------- Not sure if this is a bug or a feature. RDoc documentation for Data::define: > define(name, *symbols) ��� class > define(*symbols) ��� class > > Defines a new Data class. > If the first argument is a string, the class is stored in Data:: constant. ```ruby M1 = Data.define('Measure', :amount, :unit) p M1 #=> M1 p M1.members #=> [:Measure, :amount, :unit] S1 = Struct.new('Measure', :amount, :unit) p S1 #=> Struct::Measure p S1.members #=> [:amount, :unit] ``` Unlike `Struct.new`, `Data.define` does not accept a name as first argument: it converts it to a symbol, and therefore a member. There is no trace of `Data::Measure` in the example above, while we do have `Struct::Measure`. -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
