From: tad.a.digger@... Date: 2017-12-03T11:07:55+00:00 Subject: [ruby-core:84064] [Ruby trunk Feature#12275] String unescape Issue #12275 has been updated by tad (Tadashi Saito). A few days ago, I attended at Ruby developers' meeting. We concluded that the implementation is immature, so I need to improve in several points before commit. * Encoding of a `undump`ed string which including `\uXXXX` before `undump` should be UTF-8 automatically * '"...".force_encoding("...")' form should be parsed * `self` must be wrapped with double quotes * We need strict handling to clarify the spec Improvements must be done in a week or so, then I'll require code reviewing. After that, I'll mention to the 2.5 release manager, naruse, to get approval to check in. \# Yes, I have to hurry...! ---------------------------------------- Feature #12275: String unescape https://bugs.ruby-lang.org/issues/12275#change-68152 * Author: asnow (Andrew Bolshov) * Status: Assigned * Priority: Normal * Assignee: tad (Tadashi Saito) * 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 ---Files-------------------------------- benchmark.rb (193 Bytes) v1.patch (8.95 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
