Issue #19544 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Closed Fixed at commit:ac8a16237c727ae2a1446ef6dc810d0e750971fb. ---------------------------------------- Bug #19544: Custom quotes inconsistency https://bugs.ruby-lang.org/issues/19544#change-103812 * Author: hurricup (Alexandr Evstigneev) * Status: Closed * Priority: Normal * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- According to `parse_percent` in `parse.y`: For `%` we should be able use ascii non alphanumeric delimiters. But, `p % jim beam ;` does not work. Presumably because of some look-ahead distincting `%` from percent-string starter. Seems it is the same for any `\s` after `%` For the explicit `%` construction, with type specifier `%[QqWwIisrx]` we should be able to use non-alphanumeric ascii characters, which includes `\s`. But: This works: ``` p %s jim beam ``` And this does not: ``` p %w jim\ beam ``` with unterminated list error. First seems unavoidable, but second looks like obvious error of finding terminating `\n` -- 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/
