file extension methods

elliottcable (elliott cable) — Sat, 17 May 2008 02:08:39 GMT

Allows you to use file extensions as methods



class File

  # Feel free to add more here, as you need them.

  Extensions = %r=^(txt|rb|markdown|textile|haml|sass|css|html|xhtml)$=i

  

  module Extension

    def method_missing(meth, *args)

      if Extensions =~ meth.to_s

        [self, '.', meth.to_s].join

      else

        super

      end # if

    end # method_missing

  end # Extension

end # File



class Symbol

  include File::Extension

end

class String

  include File::Extension

end



'myfile'.html

# => "myfile.html"



:a_file.rb

# => "a_file.rb"

CSS true centering

elliottcable (elliott cable) — Wed, 19 Mar 2008 07:30:22 GMT

This will truely center something in CSS. Not tested in IE, knowing IE, it will burn in flames.



#center-me { /* There can be only one Centerlander! */

  height: 100%;

  display: table !important;

  margin: auto;

}



#center-me > * {

  display: table-cell !important; /* Don't touch me! I MEAN IT! DON- ... don't touch me. Really, don't touch me. */

  vertical-align: middle !important;

}





  I'm centered!

quote-delineated tag sets

elliottcable (elliott cable) — Thu, 13 Mar 2008 21:16:57 GMT

snippet to surround a tag with “smart quotes” if it contains any odd characters. i.e. to display tags entered in a flickr-like style (space separated except inside quotes)



tag.gsub(/^/,'“').gsub(/$/,'”') if tag[0].match(/[^A-Za-z0-9\-_.]/)

abbr formatting

elliottcable (elliott cable) — Thu, 13 Mar 2008 21:13:51 GMT

haml (easily transformed to css) snippet to format abbrs in a proper manner - you can still type them in ALL CAPS, but they will be displayed in Titlecase and small-caps. If you're using this, you're probably also using a custom face via @font-face, so you might want to explicitly declare the small-caps and lowercase variants of the typeface - the browser often fucks up auto-small-caps.

also, not tested in internet explorer. nothing I write is.



abbr

  :display inline-block

  :text-transform lowercase

  :font-variant small-caps

  

  &:first-letter

    :text-transform uppercase

[ruby] plugin structure

elliottcable (elliott cable) — Thu, 21 Feb 2008 06:42:15 GMT

plugin structure sorta thing. Use inherited to concatenate all plugins to a library in a Plugins constant in said library.



class Library

  Plugins = []

  

  def initialize#(...)

    Plugins.each do |plugin|

      # Here you can run a certain class method or grab some data from each class

    end

  end

  

  # ...

end



class LibraryPlugin

  # ...

  

  def self.inherited(sub); Library::Plugins << sub; end

end



class LibraryFooer < LibraryPlugin

  

end

class LibraryBarer < LibraryPlugin

  

end

Library::Plugins.inspect #=> [LibraryFooer, LibraryBarer]

[Ruby] Script/bot to send MediaWiki Recent Changes over UDP to a Campfire room

elliottcable (elliott cable) — Sat, 26 Jan 2008 14:29:08 GMT

Requires the Tinder gem, and PHP on the server running MediaWiki must be compiled with --enable-sockets. The computer running the bot will also have to be open to the web - it can't be behind a firewall.

First, add this code to your MediaWiki LocalSettings.php, replacing the IP address with the IP of the server/computer running the bot, and the port to whatever you want to use (probably something above 40,000, but it's up to you):



$wgRC2UDPAddress = '69.178.6.244';

$wgRC2UDPPort = '41895';

$wgRC2UDPPrefix = "";

Now, you can run the bot! This is extremely hackish, because the retarded collective-mailing-list-coding system of the MediaWiki repos has somehow managed to code IRC color codes directly into their exported strings (at least with MediaWiki 1.2alpha, which is what I'm running right now).
You'll need to replace the new tinder definition with your subdomain on Campfire, the username and password with ones for the bot account you've created on your campfire room, and the room name with the room you want the updates to be sent to.



require 'rubygems'

require 'tinder'

require 'socket'

puts 'Dependencies loaded...'



campfire = Tinder::Campfire.new 'subdomain'

campfire.login 'email@domain.com', 'password'

exit unless room = campfire.find_room_by_name('Case Sensitive Room Name')

puts 'Campfire logged in...'



server = UDPSocket.new

exit unless server.bind('0.0.0.0', 41895)

puts 'Socket listening...'



loop do

  msg = server.recv(2048).gsub(/\003[\d]{0,2}/,'').chomp

  print "sending to room: #{msg.inspect}..."

  exit unless room.speak msg.to_s

  puts ' sent!'

end

ruby: random alphanumeric string

elliottcable (elliott cable) — Mon, 21 Jan 2008 09:03:01 GMT

generate random alphanumeric string 'size' characters long

size = 8; (1..size).map{([*('a'..'z')]+[*('A'..'Z')]+[*(1..9)].map{|n|n.to_s}).instance_eval{self[rand(self.size)]}}.join

Ruby dictionary username generation

elliottcable (elliott cable) — Thu, 13 Sep 2007 13:57:59 GMT

Generate a new random name from dictionary words.



DICT_PATH = '/usr/share/dict/words'

DICT_SIZE = 234936



def self.generated_name words = 2, length = 23

  name = 'a'*(length+1)

  while name.length > length

    name = (1..words).map{%x[sed -n '#{rand(DICT_SIZE)} {p;q;}' '#{DICT_PATH}'].chomp.capitalize}.join

  end

end
