ruby-2.0

I see this a lot and haven't figured out a graceful solution. If user input contains invalid byte sequences, I need to be able to have it not raise an exception. For example: # @raw_response comes from user and contains invalid UTF-8 # for example: @raw_response = "\xBF" regex.match(@raw_response) ArgumentError: invalid byte sequence in UTF-8 Numerous similar questions have been asked and the result appears to be encoding or force encoding the string. Neither of these work for me however: regex.match(@raw_response.force_encoding("UTF-8")) ArgumentError: invalid byte sequence in UTF-8 or regex

With this regex: regex1 = /\z/ the following strings match: "hello" =~ regex1 # => 5 "こんにちは" =~ regex1 # => 5 but with these regexes: regex2 = /#$/?\z/ regex3 = /\n?\z/ they show difference: "hello" =~ regex2 # => 5 "hello" =~ regex3 # => 5 "こんにちは" =~ regex2 # => nil "こんにちは" =~ regex3 # => nil What is interfering? The string encoding is UTF-8, and the OS is Linux (i.e., $/ is "\n" ). Are the multibyte characters interfering with $/ ? How? The problem you reported is definitely a bug of the Regexp of RUBY_VERSION #=> "2.0.0" but already existing in previous 1.9 when the encoding allow multi

I am creating a test application using following versions of rails, ruby and mongoid. rails 4 beta ruby 2.0.0 mongoid 3.1.2 My GemFile looks like this gem 'rails', '4.0.0.beta1' ruby '2.0.0' gem 'mongoid', '~> 3.1.2' gem 'bson_ext' But when i run bundle on console I get following error.

why ruby is prepends '\' character while I am trying to run below code. It is happening with only '#$' It is happening with all ruby version. puts '#$' => '\#$' or '#$' => '\#$' or 'mypassord#$123' => 'mypassord\#$123' Please share you experience here. Is it a ruby problem or anything? No it is not a ruby problem. It is your problem. Since #$foo can be interpreted as interpolation of the global variable $foo , it is necessary to escape the # character. That is why there is a backslash. To be more precise, there is no possibility of interpolation with the string "#$" ( $ is an invalid global

I am trying to install SASS on Windows 8 x64, but still getting errors, even when my firewall is switched off. I make this command: C:\Ruby200-x64\bin>gem install sass (or C:\Ruby200-x64\bin>ruby -S gem install sass) I get this response: ERROR: Could not find a valid gem 'sass' (>= 0), here is why: Unable to download data from http://rubygems.org/ - Errno::EACCES: Per mission denied - connect(2) (http://rubygems.org/latest_specs.4.8.gz) Does anybody know how to solve this problem, please? This is work for me. Try this... gem source -a http://rubygems.org/ answer y to the question "Do you want

Enumerable#lazy relies on your enumerable providing an #each method. If your enumerable doesn't have an #each method you can't use #lazy . Now Kernel#enum_for and #to_enum provide the flexibility to specify an enumeration method other than #each : Kernel#enum_for(method = :each, *args) But #enum_for and friends always construct plain (non-lazy) enumerators, never Enumerator::Lazy . I see that Enumerator in Ruby 1.9.3 offers this similar form of #new: Enumerator#new(obj, method = :each, *args) Unfortunately that constructor has been completely removed in Ruby 2.0. Also I don't think it was ever

I'm using ruby 2.0.0-p195 on OSX. pry-debugger does not work (step/continue/next all appear to work like continue ). Is there a pry debugging gem that works with ruby 2.0? update: pry-debugger and pry-byebug both appear to work with with ruby 2.0.0-p195 in a simple project. I have some other conflict that is causing both to fail when using binding.pry in tests... update: pry-byebug is working for me with the latest ruby 2.0 release, 2.0.0-p247, with pry-byebug 1.1.1 & byebug 1.5.0 pry-byebug 1.1.1+ works with ruby 2.0.0-p247. It's a fork of pry-debugger & works with ruby 2.0+ only. gem 'pry
