ruby-core #113792
Issue #19718 has been updated by Dan0042 (Daniel DeLorme). It's a nifty idea, but `-0uCODEPOINT` means that the `-u` option is forever reserved for this usage which no one will ever really use I think, because `-0` is meant to be used like xargs `-0` option (ex: `find . -print0 | ruby -0ne 'p $_.chomp'`) and I can't imagine why anyone would use anything other than NUL. Although I would love to be shown wrong. `-0:separator` doesn't have that downside. ---------------------------------------- Feature #19718: Extend `-0` option https://bugs.ruby-lang.org/issues/19718#change-103438 * Author: nobu (Nobuyoshi Nakada) * Status: Open * Priority: Normal ---------------------------------------- Recently I learned that Perl's `-0` option is extended to accept a hexadecimal Unicode codepoint. However it uses `-0x`, and since `-x` is used for shebang and cd, it would cause a backward incompatibility if we will incorporate it as it is. So I propose that `-0uCODEPOINT` instead. This can be extended to comma- or colon-separated codepoint list. Also, another idea is `-0:sepaerator` which specifies the separator as-is. Considering many of modern shells provide escaped string form (e.g., `$'\uHHHH'), this may be a more modern answer, except for NUL cannot be represented. https://github.com/ruby/ruby/pull/7914 -- 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/
