Issue #12275 has been updated by tad (Tadashi Saito). Thank you for your comments. > I think rather than using true/false to distinguish single and double quotes, it would be better to have a keyword parameter, such as quotes: :single (and quotes: :double, but that would be default). I think we can forget about arguments (i.e. additional quotes), because current implementation never uses `eval()` internally. My `String#undump` takes no argument just like: ~~~ruby '"\u00FC"'.undump #=> "" ~~~ I'll write detailed specs when I submit a patch. Basically I focused to does inverse of `String#dump`. > Also, please think about encodings. Some people may want all non-ASCII characters escaped, but others may not want that at all. Unfortunately, I couldn't understand your concern. I think we're discussing about unescaping/undumping, not escaping. Note that `String#dump` already escapes all of non-ASCII characters, so I'm trying to unescape them all with `undump`. ---------------------------------------- Feature #12275: String unescape https://bugs.ruby-lang.org/issues/12275#change-67913 * Author: asnow (Andrew Bolshov) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- I think it will be usefull to have function that convert input string as it was written in prime qouted string or in double qouted string. It's part of metaprogramming. Example: ~~~ ruby class String # Create new string like it will be writed in qoutes. Optional argument define type of qouting used: true - prime qoute, false - double qoute. Default is double qoute. def unescape prime = false eval( prime ? "'#{self}'" : "\"#{self}\"" ) end end "\\\t".unescape # => "\t" ~~~ Other requests: http://www.rubydoc.info/github/ronin-ruby/ronin-support/String:unescape http://stackoverflow.com/questions/4265928/how-do-i-unescape-c-style-escape-sequences-from-ruby http://stackoverflow.com/questions/8639642/best-way-to-escape-and-unescape-strings-in-ruby Realized http://www.rubydoc.info/github/ronin-ruby/ronin-support/String:unescape -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request / ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
