  • format string (postcode) in ruby

    - by noddy
    I need to re-format a list of UK postcodes and have started with the following to strip whitespace and capitalize: postcode.upcase.gsub(/\s/,'') I now need to change the postcode so the new postcode will be in a format that will match the following regexp: ^([A-PR-UWYZ0-9][A-HK-Y0-9][AEHMNPRTVXY0-9]?[ABEHMNPRVWXY0-9]? {1,2}[0-9][ABD-HJLN-UW-Z]{2}|GIR 0AA)$ I would be grateful of any assistance.

  • Advanced Array Sorting in Ruby

    - by Ruby Beginner
    I'm currently working on a project in ruby, and I hit a wall on how I should proceed. In the project I'm using Dir.glob to search a directory and all of its subdirectories for certain file types and placing them into an arrays. The type of files I'm working with all have the same file name and are differentiated by their extensions. For example, txt_files = Dir.glob("**/*.txt") doc_files = Dir.glob("**/*.doc") rtf_files = Dir.glob("**/*.rtf") Would return something similar to, FILECON.txt ASSORTED.txt FIRST.txt FILECON.doc ASSORTED.doc FIRST.doc FILECON.rtf ASSORTED.rtf FIRST.rtf So, the question I have is how I could break down these arrays efficiently (dealing with thousands of files) and placing all files with the same filename into an array. The new array would look like, FILECON.txt FILECON.doc FILECON.rtf ASSORTED.txt ASSORTED.doc ASSORTED.rtf etc. etc. I'm not even sure if glob would be the correct way to do this (all the files with the same file name are in the same folders). Any help would be greatly appreciated!

  • Perl vs Python: implementation of algorithms to deal with advanced data structures

    - by user350571
    I'm learning perl and everytime I search for perl stuff in the internet I get some random page with people saying that perl should die because code written in it looks like a lesson in steganography. Then they say that python is clean and stuff like that. Now, I know that those comparisons are always stupid and made by fellows that feel that languages are a extension of their boring personality so, let me ask instead: can you give me the implementation of a widely known algorithm to deal with a data structure like red-black trees in both languages so I can compare?

  • "Decompile" Javascript function? *ADVANCED*

    - by caesar2k
    [1] Ok, I don't even know how to call this, to be honest. So let me get some semi-pseudo code, to show what I'm trying to do. I'm using jquery to get an already existing script declared inside the page, inside a createDocument() element, from an AJAX call. GM_xmlhttprequest({ ... load:function(r){ var doc = document_from_string(r.responseText); script_content = $('body script:regex(html, local_xw_sig)', doc).html(); var scriptEl = document.createElement('script'); scriptEl.type = 'text/javascript'; scriptEl.innerHTML = script_content; // good till here (function(sc){ eval(sc.innerHTML); // not exactly like this, but you get the idea, errors alert('wont get here ' + local_xw_sig); // local_xw_sig is a global "var" inside the source })(scriptEl); } }); so far so good, the script indeed contains the source from the entire script block. Now, inside this "script_content", there are auto executing functions, like $(document).ready(function(){...}) that, everything I "eval" the innerHTML, it executes this code, halting my encapsulated script. like variables that doesn't exist, etc removing certain parts of the script using regex isn't really an option... what I really wanted is to "walk" inside the function. like do a (completely fictional): script = eval("function(){" + script_content + "};"); alert(script['local_xw_sig']); // a03ucc34095cw3495 is there any way to 'disassemble' the function, and be able to reach the "var"s inside of it? like this function: function hello(){ var message = "hello"; } alert(hello.message); // message = var inside the function is it possible at all? or I will have to hack my way using regex? ;P [2] also, is there any way I can access javascript inside a document created with "createDocument"?

  • Advanced Rails Routing of short URL's and usernames off of root url

    - by Michael Waxman
    I want to have username URL's and Base 58 short URL's to resources both off of the root url like this: http://mydomain.com/username #=> goes to given user http://mydomain.com/a3x9 #=> goes to given story I am aware of the possibilities of a user names conflicting with short urls, and I have a workaround, but what I can't figure out is the best way to set this up in rails. Can I do it in rails routes? Should I do something with a piece of Rack middleware? Should I set up a routing controller? Please let me know the best way to do this. Thanks so much!

  • Retactoring advanced has_many example

    - by atmorell
    Hello, My user model has three relations for the same message model, and is using raw SQL :/ Is there a better more rails way to achieve the same result? Could the foreign key be changed dynamically? e.g User.messages.sent (foreign key = author_id) and User.messages.received (foreign key = recipient ) I have been trying to move some of the logic into scopes in the message model, but the user.id is not available from the message model... Any thoughts? Table layout: create_table "messages", :force => true do |t| t.string "subject" t.text "body" t.datetime "created_at" t.datetime "updated_at" t.integer "author_id" t.integer "recipient_id" t.boolean "author_deleted", :default => false t.boolean "recipient_deleted", :default => false end This is my relations for my user model: has_many :messages_received, :foreign_key => "recipient_id", :class_name => "Message", :conditions => ['recipient_deleted = ?', false] has_many :messages_sent, :foreign_key => "author_id", :class_name => "Message", :conditions => ['author_deleted = ?', false] has_many :messages_deleted, :class_name => "Message", :finder_sql => 'SELECT * FROM Messages WHERE author_id = #{self.id} AND author_deleted = true OR recipient_id = #{self.id} AND recipient_deleted = true' Best regards.

  • Finding duplicate values in a SQL table - ADVANCED

    - by Alex
    It's easy to find duplicates with one field SELECT name, COUNT(email) FROM users GROUP BY email HAVING ( COUNT(email) > 1 ) So if we have a table ID NAME EMAIL 1 John [email protected] 2 Sam [email protected] 3 Tom [email protected] 4 Bob [email protected] 5 Tom [email protected] This query will give us John, Sam, Tom, Tom because they all have the same e-mails. But what I want, is to get duplicates with the same e-mails and names. I want to get Tom, Tom. I made a mistake, and allowed to insert duplicate name and e-mail values. Now I need to remove/change the duplicates. But I need to find them first.

  • Hibernate advanced select

    - by Marcus
    We want to get a row from a table using Hibernate a la: select max(id) from mytable where date = <date> Then select * from mytable where id = <max_id> We are currently using Hibernate to map mytable to Java domain objects. I know how to load the domain object based on an id. So I could just do #1 using JDBC and then load the domain object using Hibernate the "normal" way. But.. is there a way to do this with one single Hibernate logical query?

  • Please recommend PDU SMS format code or library for .NET or C++

    - by Pavel Radzivilovsky
    I have been searching a lot for a chunk of code, or a library to format SMS messages in PDU format and had little luck. They were either huge monsters with terrific dependencies on everything way above my requirements and a very obscure interface, totally not justifying the straight-forward, although rather complex encoding. Being on the edge of creating a NIH, my question is - have encountered the same problem and how have you solved it?

  • Drupal: Template Files, Modules and Content Types for Advanced Theme

    - by theandym
    Intro I am in the process of trying to convert my first HTML/CSS design into a theme for Drupal. I have used ModX for quite a few designs and appreciate the ability to create different page templates and custom variables to be assigned to those templates. However I seem to be having some issues making the transition. The site I am working on theming in Drupal is for a real estate agent. Each page/section will have a different set of content associated with it and will need to display only that content. For example, there will be a page for current listings, each of which will be formatted by a custom content type. However, when I call the content on the home page (or on other pages) I do not want to see this listing data. Layout The layout of the site and the regions associated with each page/section is as follows: Home Spotlight Featured 1 Featured 2 About Spotlight Bios - Profiles of each agent (each will be a node with name, contact info, pic, etc) listed on the page; multiple nodes listed Sidebar Listings Spotlight Listings - Profiles of properties (each will be a node with locations, basic info, pic, etc) listed on the page; multiple nodes listed Sidebar Services Spotlight Content - general paragraph text area Sidebar News/Blog News/Blog Items - List of stories with summaries and links to full article Sidebar Each page/section will use the same header and footer. Issue I have done some reading on Drupal, custom content types (and CCK), Views, and Pathauto. However I have not been able to get a clear picture of how to put it all together to accomplish what I am attempting. What I really would like to know is which modules to use, how best to use them, which elements I need to use where, and what template files I should be using to theme the elements I need to use. Any help or reference to useful resources would be much appreciated.

  • What is the best way to format a date in JSON for Mongo DB storage

    - by Poul
    I have a date with a time. I'm using ruby, but the language shouldn't matter. d = "2010-04-01 13:00:00" What is the best way to format this date for Mongo DB? By 'best' I mean, is there a certain format I could use where Mongo would recognize it as a date and might give me more-advanced filtering optons? ie: If formatted correctly, could I ask Mongo to return all records whose month is '04'? Thanks!

  • Advanced command line argument parsing in Java?

    - by Bishop87
    Does anyone have any java examples for parsing a series of command line arguements in a robust way? I'm looking to be able to handle something like: java myapp [-l language] [-d int] [-f file1 file2 file3] I want to do this in a robust way so I can provide logical error messages to the user if they mistake a command line-option. Some of these options I'd like to make optional, etc, etc. Also, the -f file list should be able to handle a list of files. Is there some library out there to assist me in handling this?

  • iPhone Pong Advanced Deflection Angle

    - by CherryBun
    Hi, I am currently developing a simple Pong game for the iPhone. Currently using CGRectIntersectsRect for the collision detection and as for the deflection of the ball when it hits the paddle, I just multiply the ball velocity with -1 (therefore reversing the direction of the ball). What I am trying to do is to make it so that when the ball hits the paddle, it checks whether how far is the ball from the center of the paddle, and increases the deflection angle the further the ball is away from the center of the paddle. (E.g. In this case, the ball will be deflected back at 90 degrees no matter where it came from, as long as it hits the center of the paddle) How am I suppose to do that? Any help would be greatly appreciated. Thank you.
