ruby-1.9

问题 This question already has answers here : Does C1 code coverage analysis exist for Ruby? [closed] (5 answers) Closed last year . Is there any tool for C1 or C2 code coverage for Ruby (1.9)? SimpleCov supports only C0, but maybe there is another tool. I'm aware that a similar question has been asked here, but it was a couple years ago and I hope that something has changed. 回答1: No, currently there is no tool that does that. There is also no technical limitation that avoids one to implement it,

问题 I have a Sinatra application (http://analyzethis.espace-technologies.com) that does the following Retrieve an HTML page (via net/http) Create a Nokogiri document from the response.body Extract some info and send it back in the response. The response should be UTF-8 encoded So I came to the problem while trying to read sites that use windows-1256 encodings like www.filfan.com or www.masrawy.com. The problem is the result of the encoding conversion is not correct though no errors are thrown.

问题 How can I set the encoding of a file when using a File#open ? 回答1: Here's an example that outputs a file in the UTF-16LE encoding: open("data.txt", "w:UTF-16LE") Ruby looks at the encoding of the string you are writing, and transcodes as necessary. Here's a very detailed blog post describing mechanics with excellent examples (see the section called "The Default External and Internal Encodings"). 回答2: That blog also has a bunch of great information about character encoding with Ruby, including

问题 Suppose you have a string like "€foo\xA0" , encoded UTF-8, Is there a way to remove invalid byte sequences from this string? ( so you get "€foo" ) In ruby-1.8 you could use Iconv.iconv('UTF-8//IGNORE', 'UTF-8', "€foo\xA0") but that is now deprecated. "€foo\xA0".encode('UTF-8') doesn't do anything, since it is already UTF-8. I tried: "€foo\xA0".force_encoding('BINARY').encode('UTF-8', :undef => :replace, :replace => '') which yields "foo" But that also loses the valid multibyte character € 回答1

问题 I have a script that iterates using ObjectSpace#each_object with no args. Then it prints how many instances exist for each class. I realized that some classes redefine the #class instance method, so I had to find another way to get the actual class; Let's say it's stored in variable "klass" , and klass === object is true. In Ruby 1.8 I could do this, assuming Object wasn't monkeypatched: Object.instance_method(:class).bind(object).call This worked for ActiveSupport::Duration instances: # Ruby

问题 I found a similar post here but I can't solve the problem anyway. I got this /home/fra/siti/Pensiero/db/seeds.rb:32: invalid multibyte char (US-ASCII) /home/fra/siti/Pensiero/db/seeds.rb:32: invalid multibyte char (US-ASCII) /home/fra/siti/Pensiero/db/seeds.rb:32: syntax error, unexpected $end, expecting ')' ... ed il valore della vita, si è malati", :user_id => 1, :cat... The problem is into this string :body => "Nel momento in cui ci si chiede il significato ed il valore della vita, si è

问题 I am new to Ruby. I have a below code in my controller. Desired Behaviour :- I want to display validation error string to my views on edit page. So I am putting those errors in a variable. When validation fails then I want to use that variable in my edit method, so that I can display that on my edit page view. Observed behaviour :- There is a variable @vpinerr in create method. I wan to use that variable in edit method. I have tried to use the class variable (@@vpinerr) and initialized it

问题 The documentation says: enum#each_with_object :- Iterates the given block for each element with an arbitrary object, obj, and returns obj enum#with_object:- Iterates the given block for each element with an arbitrary object, obj, and returns obj But when I tried the below on the both constructs, one gave me the output as expected but the others didn't. So I suspect there is a difference between those two constructs. Using each_with_object %w(foo bar).each_with_object({}) { |str, hsh| hsh[str]
