  • Is Spring hard compared to Ruby on Rails?

    - by johnny
    If I have no to little experience in either of them, but know enough Java and Ruby to be comfortable, is one framework harder to learn than the other? Is one easier to use for the beginner on these? I know it is hard to answer. Just looking for general thoughts on it.

  • Ruby: Allowing a module to have settings

    - by JP
    If I'm building a library in ruby, what's the best way to allow users of the library to set module-wide settings that will be available to all sub classes etc of the library? A good example would be if I'm writing a library for posting to a webservice: TheService::File.upload("myfile.txt") # Uploads anonymously TheService::Settings.login("myuser","mypass") # Or any other similar way of doing this TheService::File.upload("myfile.txt") # Uploads as 'myuser' The idea would be that unless TheService::Settings.logout is called then all TheService operations would be conducted under myuser's account. Any ideas?

  • Ruby hash value truthiness and symbols

    - by John Topley
    Could somebody please explain why the variable named foo remains true in the code below, even though it's set to false when the method is called? And why the symbol version behaves as expected? def test(options = {}) foo = options[:foo] || true bar = options[:bar] || :true puts "foo is #{foo}, bar is #{bar}" end >> test(:foo => false, :bar => :false) foo is true, bar is false I've only tried this using Ruby 1.8.7.

  • Getting a substring in Ruby by x number of chars

    - by wotaskd
    I'm trying to produce some Ruby code that will take a string and return a new one, with a number x number of characters removed from its end - these can be actual letters, numbers, spaces etc. Ex: given the following string a_string = "a1wer4zx" I need a simple way to get the same string, minus - say - the 3 last digits. In the case above, that would be "a1wer". The way I'm doing it right now seems very convoluted: an_array = a_string.split(//,(a_string.length-2)) an_array.pop new_string = an_array.join Any ideas?

    - by turri
    I need to run multiple background threads in a thread pool with timeout. The scheme is something like: #!/usr/bin/env ruby require 'thread' def foo(&block) bar(block) end def bar(block) Thread.abort_on_exception=true @main = Thread.new { block.call } end foo { sleep 1 puts 'test' } Why if i run that i get no output? (and no sleep wait?)

  • ruby sortby 3rd element in a multidimential array npot working properly

    - by Steven
    Hi, I'm using ruby to sort an array where each element in the array is another array. I have this: Data = Data.SortBy { |Info| info[3] } example data in this column: 3.1 2 5.65 -1 0.4 -9.43 -10.87 -2.3 It should sort this into: 5.65 3.1 2 0.4 -1 -2.3 -9.43 -10.87 But it comes out like this: 5.65 3.1 2 0.4 -1 -10.87 -2.3 -9.43 It's only comparing the first char of the float... not the whole number?

  • rb_str_modify() equivalent in the Ruby language

    - by Hagbard
    I was trying to add a method to the String class. This method should mutate the current string (of course it would be possible to write a not mutating version but I'd prefer the mutating one). I had no idea how to do this and after some googling I found the method rb_str_modify which makes a given string mutable. That's exactly what I need but I couldn't find an equivalent in the Ruby language. Did I miss something or is there really no possibility in the language itself?

  • Replace all "&gt;"(>) which are inside <code> tags

    - by Micke
    How can i replace all &gt; with > and &lt; with < inside a <code> tag with ruby? For example: <code>&lt;script&gt;alert('I steal cookies');&lt;/script&gt;</code> With: <code><script>alert('I steal cookies);<script><code> The reason for this is because the h() method escapes all the < and > Thanks, Micke

  • Why do users have to enter a 7-digit twitter PIN to grant my application access?

    - by Tony
    I am implementing some ruby on rails code tweet stuff for my users. I am creating the proper oauth link...something like http://twitter.com/oauth/authorize?oauth_token=y2RkuftYAEkbEuIF7zKMuzWN30O2XxM8U9j0egtzKv But after my test account grants access to twitter, it pulls up a page saying "You've successfully granted access to . Simply return to and enter the following PIN to complete the process. 1234567" I have no idea where the user should enter this PIN and why they have to do that. I don't think this should be a necessary step. Twitter should be redirecting the user to the callback URL I provided in the application settings. Does anyone know why this is happening? UPDATE I found this article that states I need to send my users to this URL (note "authenticate" instead of "authorize"): http://twitter.com/oauth/authenticate?oauth_token=y2RkuftYAEkbEuIF7zKMuzWN30O2XxM8U9j0egtzKv I made the change but Twitter redirects the user to the authorize path after he clicks "Allow" which then gives him the 7 digit PIN again!
