• What does @@variable mean in Ruby?

  - by Andrew

  What are Ruby variables preceded with double at signs (@@)? My understanding of a variable preceded with an at sign is that it is an instance variable, like this in PHP: PHP version class Person { public $name; public function setName($name) { $this->name = $name; } public function getName() { return $this->name; } } Ruby equivalent class Person def set_name(name) @name = name end def get_name() @name end end What does the double at sign @@ mean, and how does it differ from a single at sign?

• Why would Silverlight be crashing in Release but not in Debug mode?

  - by Edward Tanguay

  I have a Silverlight App that has worked well in Debug and Release modes for weeks. It still works well in Debug mode. However, now when I run it in Release mode, it starts, shows me the screen, loads the data, then hangs, and the browser (Firefox) closes automatically. I've tried other browsers and each of them crashes, Chrome says "The Silverlight Plug-In has crashed" for instance. Here are the last lines of Output that I get: 'firefox.exe' (Silverlight): Loaded 'System.Windows.Controls' 'firefox.exe' (Silverlight): Loaded 'System.Windows.Controls.Toolkit' 'firefox.exe' (Silverlight): Loaded 'C:\Program Files\Microsoft Silverlight\4.0.50524.0\en-US\mscorlib.debug.resources.dll' 'firefox.exe' (Silverlight): Loaded 'C:\Program Files\Microsoft Silverlight\4.0.50524.0\en-US\System.Windows.debug.resources.dll' The program '[1120] firefox.exe: Silverlight' has exited with code -2147023895 (0x800703e9). How can I get more information about what is happening at the point of crash in Release mode that is not happening in Debug mode?

• Which Language Next? Python? Ruby? [closed]

  - by Ryan Craig

  I am a beginning Webmaster (relatively), with 2+ years of php experience. I also have some java training and a bit of .net. My company is now close to redeveloping the website that I work on, which is coded primarily in php, but has some poorly-written .net in part as well (it's confusing and ill-planned, but I didn't make any of those decisions. Can anyone say action-oriented .net and JScript?). So, I'm trying to decide which language I should learn next to quickly develop a new site. I will probably just redevelop it at first in php because I'm very comfortable with it. However, I'd like to migrate in the next year to something newer and more forward-thinking. This being said, .net is out of the question a little bit. We need cheap developers who are fast and can get pages up quickly. In this part of the country, part-time .net developers are hard to find. So, we need something that will be pretty standard in the next few years, but we have some .net SOAP 1.1 APIs that we use on our actual service (separate from the corporate website), that we will need to integrate part of the site with. Developing with php and SOAP is much more difficult than doing the same thing. So, I may have to develop the API collaborative part in .net just to be easy, and then I'd like to use something else that is fast, flexible, forward thinking, and will be relatively standard and easy to find developers for. So, any ideas? Python and Django? Ruby on Rails? Another framework? Thanks for your thoughts. Sorry, I know this was long, but it's all very convoluted and confusing so I needed to be slightly long-winded.

• vim + Ruby on Rails: how do you bounce among those 4-5 files you're currently working on?

  - by glitch

  I'm just starting to get familiar with vim, and I'd like to use it as my primary Rails development tool. As a Visual Studio and RubyMine user, I find a lot of stuff to be missing from the barebones vim installation, and therefore I went ahead and attempted to soup it up with plugins such as: rails.vim tcomment ruby-vim NERDtree and a couple of others. The issue is that I still don't quite get the average work-flow of using vim as one's Rails IDE. In RubyMine (again, similarly to Visual Studio) I have a series of tabs always open, containing the main files I'm switching among, and I additionally use NERDtree to open files from the folder structure. I tried opening them as new tabs, but the tab system in vim is just a lot more awkward than that in real IDEs. (I haven't seen vim pros in action, but I imagine that they'd not be relying on tabs, but using numerous splits instead, keeping at least a couple of files per split and switching between them with CTRL + ^. Is that the case?) So, at the end of the day, how do I really squeeze the most from vim if I want to be able to quickly access several files at once? Thank you!

• Ruby (on Rails) && PHP - two great things that work great together???

  - by pedalpete

  I've done very little work with Ruby, and have an app I've written in PHP. I would like to add some functionality which is available in open sourced Ruby code. I could either try to translate the Ruby to PHP, or try mixing the two. Though I think the mixing part would be somewhat silly. I believe my options are to either mix ruby with php, or translate the ruby code into php. Anybody have any suggestions on this, or other ideas? I am not really interested in converting my entire app into Ruby just so I can get this feature (I saw Derek Sivers post about that which convinced me. http://www.oreillynet.com/ruby/blog/2007/09/7%5Freasons%5Fi%5Fswitched%5Fback%5Fto%5Fp%5F1.html)

• How can install sqlite-ruby on linux when sqlite3 is not in /usr/local ?

  - by Charles

  I am trying to install sqlite3 and sqlite-ruby (ruby 1.8.6) on a linux box where I do not have root. I downloaded the sqlite3 source, binaries, and shared library and placed them all in a directory called sqlite3 I then try to install sqlite-ruby using gem install sqlite-ruby --with-sqlite-dir=the_path_sqlite/sqlite3 but I keep getting the error... checking for main() in -lsqlite... no checking for sqlite.h... no * extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=/data/scratch/bettbra/common/packages/ruby-1.8.6/bin/ruby --with-sqlite-dir --with-sqlite-include --without-sqlite-include=${sqlite-dir}/include --with-sqlite-lib --without-sqlite-lib=${sqlite-dir}/lib --with-sqlitelib --without-sqlitelib

  Hi, I start to using cassandra and I want to index my db with sphinx.

• Ruby Shoes packager including Shoes in the app

  - by user206481

  I can't seem to get the Ruby Shoes packager to correctly create an exe with Shoes included. I'm using the Raisins release (0.r1134), with the pack.rb replaced from github. The exe's the packager makes are all 70-80K files (they obviously don't include shoes or ruby). These exe's will run on my XP machine that already has Shoes on it. but when I copy them to another laptop they start a "Shoes is downloading" dialog that does nothing and then goes away. I need to make standalone Windows exe's, and my understanding was that the "Yes, I want Shoes included" option in the packager would do that. Did I misunderstand the intent? Is there a way to make this work? Hope so, because I love Shoes. As most women do. Hmm... maybe Shoes was _why's attempt at getting more women into programming as well as kids...but I digress. The other threads I've found here imply this will work: http://stackoverflow.com/questions/1390721/problem-in-ruby-shoes-packaging http://stackoverflow.com/questions/363218/shoes-packager-problem

• search and replace with ruby regex

  - by randombits

  I have a text blob field in a MySQL column that contains HTML. I have to change some of the markup, so I figured I'll do it in a ruby script. Ruby is irrelevant here, but it would be nice to see an answer with it. The markup looks like the following: <h5>foo</h5> <table> <tbody> </tbody> </table> <h5>bar</h5> <table> <tbody> </tbody> </table> <h5>meow</h5> <table> <tbody> </tbody> </table> I need to change just the first <h5>foo</h5> block of each text to <h2>something_else</h2> while leaving the rest of the string alone. Can't seem to get the proper PCRE regex, using Ruby.

• Strange \n in base64 encoded string in Ruby

  - by intellidiot

  The inbuilt Base64 library in Ruby is adding some '\n's. I'm unable to find out the reason. For this special example: irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'base64' => true irb(main):003:0> str = "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" => "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" irb(main):004:0> Base64.encode64(str) => "MTExMC0tYWQ2Y2EwYjA2ZTFmYmViN2U2NTE4YTA0MThhNzNhNmUwNGE2NzA1\nNA==\n" The \n's are at the last and 6th position from end. The decoder (Base64.decode64) returns back the old string perfectly. Strange thing is, these \n's don't add any value to the encoded string. When I remove the newlines from the output string, the decoder decodes it again perfectly. irb(main):005:0> Base64.decode64(Base64.encode64(str).gsub("\n", '')) == str => true More of this, I used an another JS library to produce the base64 encoded output of the same input string, the output comes without the \n's. Is this a bug or anything else? Has anybody faced this issue before? FYI, $ ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

• Ruby custom class to and from YAML;

  - by Sanarothe

  Hi. I'm having trouble deserializing a ruby class that I wrote to YAML. Where I want to be I want to be able to pass one object around as a full 'question' which includes the question text, some possible answers (For multi. choice) and the correct answer. One module (The encoder) takes input, builds a 'question' class out of it and appends it to the question pool. Another module reads a question pool and builds an array of 'question' objects. Where I am currently Sample Question Pool --- | --- !ruby/object:MultiQ a: "no" answer: "no" b: "no" c: "no" d: "no" text: "yes?" Encoder dump to YAML file. Object is a MultiQ filled up with input. (See below.) def dump(file, object) File.open(file, 'a') do |out| YAML.dump(object.to_yaml, out) end object = nil end MultiQ Class definition class MultiQ attr_accessor :text, :answer, :a, :b, :c, :d def initialize(text, answer, a, b, c, d) @text = text @answer = answer @a = a @b = b @c = c @d = d end end The decoder (I've been trying different things, so what's here wasn't my first or best guess. But I'm at a loss and the documentation doesn't really explain things thoroughly enough.) File.open( "test_set.yaml" ) do |yf| YAML.load_documents( yf ) { |item| new = YAML.object_maker( MultiQ, item) puts new } end Questions you can answer How do I achieve my goal? What methods should I use, between parsing, loading files or documents, to successfully deserialize a Ruby class? I've already looked over the YAML Rdoc, and I didn't absorb very much, so please don't just link me to it. What other methods would you suggest using? Is there a better way to store questions like this? Should I be using document db, relational db, xml? Some other format?

• What is Ruby's analog to Python Metaclasses?

  - by Sean Copenhaver

  Python has the idea of metaclasses that, if I understand correctly, allow you to modify an object of a class at the moment of construction. You are not modifying the class, but instead the object that is to be created then initialized. Python (at least as of 3.0 I believe) also has the idea of class decorators. Again if I understand correctly, class decorators allow the modifying of the class definition at the moment it is being declared. Now I believe there is an equivalent feature or features to the class decorator in Ruby, but I'm currently unaware of something equivalent to metaclasses. I'm sure you can easily pump any Ruby object through some functions and do what you will to it, but is there a feature in the language that sets that up like metaclasses do? So again, Does Ruby have something similar to Python's metaclasses? Edit I was off on the metaclasses for Python. A metaclass and a class decorator do very similar things it appears. They both modify the class when it is defined but in different manners. Hopefully a Python guru will come in and explain better on these features in Python. But a class or the parent of a class can implement a __new__(cls[,..]) function that does customize the construction of the object before it is initialized with __init__(self[,..]).

• ruby on rails: undefined method "version_requirements' when attempting to start server after new install

• ruby comma operator and step question

  - by ryan_m

  so, i'm trying to learn ruby by doing some project euler questions, and i've run into a couple things i can't explain, and the comma ?operator? is in the middle of both. i haven't been able to find good documentation for this, maybe i'm just not using the google as I should, but good ruby documentation seems a little sparse . . . 1: how do you describe how this is working? the first snippet is the ruby code i don't understand, the second is the code i wrote that does the same thing only after painstakingly tracing the first: #what is this doing? cur, nxt = nxt, cur + nxt #this, apparently, but how to describe the above? nxt = cur + nxt cur = nxt - cur 2: in the following example, how do you describe what the line with 'step' is doing? from what i can gather, the step command works like (range).step(step_size), but this seems to be doing (starting_point).step(ending_point, step_size). Am i right with this assumption? where do i find good doc of this? #/usr/share/doc/ruby1.9.1-examples/examples/sieve.rb # sieve of Eratosthenes max = Integer(ARGV.shift || 100) sieve = [] for i in 2 .. max sieve[i] = i end for i in 2 .. Math.sqrt(max) next unless sieve[i] (i*i).step(max, i) do |j| sieve[j] = nil end end puts sieve.compact.join(", ")

• Ruby Design Problem for SQL Bulk Inserter

  - by crunchyt

  This is a Ruby design problem. How can I make a reusable flat file parser that can perform different data scrubbing operations per call, return the emitted results from each scrubbing operation to the caller and perform bulk SQL insertions? Now, before anyone gets narky/concerned, I have written this code already in a very unDRY fashion. Which is why I am asking any Ruby rockstars our there for some assitance. Basically, everytime I want to perform this logic, I create two nested loops, with custom processing in between, buffer each processed line to an array, and output to the DB as a bulk insert when the buffer size limit is reached. Although I have written lots of helpers, the main pattern is being copy pasted everytime. Not very DRY! Here is a Ruby/Pseudo code example of what I am repeating. lines_from_file.each do |line| line.match(/some regex/).each do |sub_str| # Process substring into useful format # EG1: Simple gsub() call # EG2: Custom function call to do complex scrubbing # and matching, emitting results to array # EG3: Loop to match opening/closing/nested brackets # or other delimiters and emit results to array end # Add processed lines to a buffer as SQL insert statement @buffer << PREPARED INSERT STATEMENT # Flush buffer when "buffer size limit reached" or "end of file" if sql_buffer_full || last_line_reached @dbc.insert(SQL INSERTS FROM BUFFER) @buffer = nil end end I am familiar with Proc/Lambda functions. However, because I want to pass two separate procs to the one function, I am not sure how to proceed. I have some idea about how to solve this, but I would really like to see what the real Rubyists suggest? Over to you. Thanks in advance :D

• Ruby : UTF-8 IO

  - by subtenante

  I use ruby 1.8.7. I try to parse some text files containing greek sentences, encoded in UTF-8. (I can't much paste here sample files, because they are subject to copyright. Really just some greek text encoded in UTF-8.) I want, for each file, to parse the file, extract all the words, and make a list of each new word found in this file. All that saved to one big index file. Here is my code : #!/usr/bin/ruby -KU def prepare_line(l) l.gsub(/^\s*[ST]\d+\s*:\s*|\s+$|\(\d+\)\s*/u, "") end def tokenize(l) l.split /['·.;!:\s]+/u end $dict = {} $cpt = 0 $out = File.new 'out.txt', 'w' def lesson(file) $cpt = $cpt + 1 file.readlines.each do |l| $out.puts l l = prepare_line l tokenize(l).each do |t| unless $dict[t] $dict[t] = $cpt $out.puts " #{t}\n" end end end end Dir.new('etc/').each do |filename| f = File.new("etc/#{filename}") unless File.directory? f lesson f end end Here is part of my output : ?@???†?†?????????? ?...[snip very long hangul/hanzi mishmash]... ????????†? ???N2 : ?e?te?? (2) µ???µa (Note that the puts l part seems to work fine, at the end of the given output line.) Any idea what is wrong with my code ? (General comments about ruby idioms I could use are very welcome, I'm really a beginner.)

• A scripting engine for Ruby?

  - by Earlz

  Hello, I am creating a Ruby On Rails website, and for one part it needs to be dynamic so that (sorta) trusted users can make parts of the website work differently. For this, I need a scripting language. In a sort of similar project in ASP.Net, I wrote my own scripting language/DSL. I can not use that source code(written at work) though, and I don't want to make another scripting language if I don't have to. So, what choices do I have? The scripting must be locked down and not be able to crash my server or anything. I'd really like if I could use Ruby as the scripting language, but it's not strictly necessary. Also, this scripting part will be called on almost every request for the website, sometimes more than once. So, speed is a factor. I looked at the RubyLuaBridge but it is Alpha status and seems dead. What choices for a scripting language do I have in a Ruby project? Also, I will have full control over where this project is deployed(root access), so there are no real limits..

• Ruby core documentation quality

  - by karatedog

  I'm relatively new to Ruby and have limited time therefore I try out simple things. Recently I needed to create a file and because I'm lazy as hell, I run to Google. The result: File.open(local_filename, 'w') {|f| f.write(doc) } Shame on me, it is very straightforward, should have done it myself. Then I wanted to check what ruby magic the File class' methods offer or if there's any 'simplification' when invoking those methods, so I headed for the documentation here, and checked for the File class. 1.8.6 documentation presents me with "ftools.rb: Extra tools for the File class" under 'File' class, which is not what I'm looking for. 1.8.7 documentation seems OK for 'File' class, there are a plethora of methods. Except 'open'. 1.9 documentation finally shows me the 'open' method. And I had an almost same tour with Net::HTTP. Do I exaggerate when I think good old Turbo Pascal's 7.0 documentation was better organized than Ruby documentation is right now? Is there any other source for the uninitiated to collect knowledge? Or is it possible that I just tumbled into a documentation hole and the rest are super-brilliant-five-star organized? Thanks

• Ruby integer to string key

  - by Gene

  A system I'm building needs to convert non-negative Ruby integers into shortest-possible UTF-8 string values. The only requirement on the strings is that their lexicographic order be identical to the natural order on integers. What's the best Ruby way to do this? We can assume the integers are 32 bits and the sign bit is 0. This is successful: (i >> 24).chr + ((i >> 16) & 0xff).chr + ((i >> 8) & 0xff).chr + (i & 0xff).chr But it appears to be 1) garbage-intense and 2) ugly. I've also looked at pack solutions, but these don't seem portable due to byte order. FWIW, the application is Redis hash field names. Building keys may be a performance bottleneck, but probably not. This question is mostly about the "Ruby way".

• Upgrading to Ubuntu 11.04 failed

  - by Rupert

  Today Ubuntu asked me to upgrade to 11.04. The installation went completely fine until right at the end when the following packages failed: install-info ubuntu-standard The installer hung so I had to shut it down manually. Ubuntu still works fine but it says that the upgrade didn't work properly so I am hesitant to restart it until I have resolved the problem in case I can't get back in. I am running Ubuntu inside the latest version of Virtual Box and was previously running version 10.10. I have tried installing install-info manually with apt-get but I get the following error: Unhandled exception: [#<SystemStackError: stack level too deep>] /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:842:in `block in <class:Autotest>': undefined method `backtrace' for [#<SystemStackError: stack level too deep>]:Array (NoMethodError) from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:828:in `[]' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:828:in `block in hook' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:828:in `each' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:828:in `any?' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:828:in `hook' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:344:in `rescue in run' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:320:in `run' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/lib/autotest.rb:241:in `run' from /usr/local/ruby/lib/ruby/gems/1.9.1/gems/ZenTest-4.5.0/bin/autotest:6:in `<top (required)>' from /usr/local/ruby/bin/autotest:19:in `load' from /usr/local/ruby/bin/autotest:19:in `<main>' dpkg: error processing install-info (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of info: info depends on install-info; however: Package install-info is not configured yet. dpkg: error processing info (--configure): dependency problems - leaving unconfigured dpkg: dependency problems prevent configuration of ubuntu-standard: ubuntu-standard depends on info; however: Package info is not configured yet. dpkg: error processing ubuntu-standard (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates it's a follow-up error from a previous failure.
