From: "naruse (Yui NARUSE) via ruby-core" Date: 2024-02-02T03:22:36+00:00 Subject: [ruby-core:116554] [Ruby master Bug#20094] Inline while loop behavior changed unexpectedly in 3.3.0 Issue #20094 has been updated by naruse (Yui NARUSE). Backport changed from 3.0: UNKNOWN, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: REQUIRED to 3.0: UNKNOWN, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONE ruby_3_3 119d447d42d4645ac919ee53f3ec294deaa7c59b merged revision(s) bc002971b6ad483dbf69b8a275c44412bb6ab954. ---------------------------------------- Bug #20094: Inline while loop behavior changed unexpectedly in 3.3.0 https://bugs.ruby-lang.org/issues/20094#change-106572 * Author: sisyphus_cg (Sisyphus CG) * Status: Closed * Priority: Normal * ruby -v: 3.3.0 * Backport: 3.0: UNKNOWN, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONE ---------------------------------------- The behavior of the inline while loop has changed in 3.3.0. This unexpectedly broke my code and I couldn't find anything in the changelog about it so reporting it as a bug. In ruby <= 3.2: ``` ruby (p 1) while false # nothing (p 1; p 2) while false # nothing ``` In ruby 3.3: ``` ruby (p 1) while false # 1 (p 1; p 2) while false # 1 2 ``` Essentially, if the left hand side looks like a statement, now it is treated as a do-while loop. In ruby 3.2 and less this only happened with explicit use of `begin` and `end`. -- 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/
