implementing yield from func() functionality by modifying yield *func() behavior

Ruby utility to pull US treasury bond yields from www.treas.gov website.

Extends standard Enumerator with a "enumerate_yields" method. Just add a one-liner piece of code to your yield method and your method can be called with or without a block. Recursion and some meta-magic greatly reduce coding.

Linefeed turns a push-style byte stream, of any chunk size, into individually yielded lines.

pressletter is a tool for solving Letterpress puzzles. Using the `pressletter` binary like this: $ pressletter eiptctbntymeiphoxvitkmzib The argument is a list of all the letters on a pressletter board and will yield an ordered list (from longest to shorted) of all legal words that can be made with the provided letters.

Tools to manipulate blat files from the command line. Uses the Bio::Blat object from BioRuby, but the parser has been modified to avoid reading the whole psl file, it yields just the current entry and it is up to the consumer to decide to store it or not." s.email = "ricardo.ramirez-gonzalez@tgac.ac.uk"

Consider the noble bamboo. This peculiar member of the Poaceae family has been known to grow to extraordinary lengths without yielding to (mostly) any obstacles. Not unlike bamboo, the i18n translations of a Rails app will continue to grow. As a tenacious stalk of bamboo breaks through a slab of sidewalk, so too will long translations break a UI. I18n:Bamboo monkey patches the Rails I18n module and will force all calls to I18n.translate (I18n.t) and I18n.localize (I18n.l) to return the longest translated or localized value from all available_locales. For obvious reasons, this gem is intended to be used for development purposes only to aid in UI and internationalization/localization testing.

* http://rubysideshow.rubyforge.org/irb_callbacks == DESCRIPTION: This gem adds callbacks to irb, intended for you to override at your discretion. == FEATURES: irb's control flow looks like this: loop: * prompt * eval * output This gem adds three callbacks to each phase. module IRB: * self.before_prompt * self.around_prompt (call yield) * self.after_prompt * self.before_eval * self.around_eval (call yield) * self.after_eval * self.before_output * self.around_output (call yield) * self.after_output == SYNOPSIS: # Here's my ~/.irbrc file (which is run at irb startup) require 'rubygems' require 'irb_callbacks' require 'benchmark' # This little snippet will time each command run via the console. module IRB def self.around_eval(&block) @timing = Benchmark.realtime do block.call end end def self.after_output puts "=> #{'%.3f' % @timing} seconds" end end # And a sample irb session: $ irb irb(main):001:0> 1_000_000.times { |x| x + 1 } => 1000000 => 0.330 seconds == CAVEATS: The three around_* callbacks all require you to call the block that's passed in. If you don't do it, undefined behavior may occur. == INSTALL: * sudo gem install irb_callbacks == LICENSE: (The MIT License) Copyright (c) 2008 Mike Judge Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the 'Software'), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

== Devise::Revokable A module for Devise[http://github.com/plataformatec/devise] This gem was created by "borrowing" heavily from Devise::Invitable[http://github.com/scambra/devise_invitable] It exists to extend Devise to provide the basis for what is essentially the reverse of the standard <tt>confirmable</tt> module. Where <tt>confirmable</tt> sends an email and awaits a response, before confirming a new registration, <tt>revokable</tt> allows immediate access and sends an email which provides a link to "revoke" the account if it was created fraudulently. This is useful if you want to lower the barrier to entry to creating accounts, and clearly, if account security isn't a concern. Note that tests are non-existent. Use freely but at your own risk. === Configuring It works like normal Devise modules. Add the <tt>:revokable</tt> module to the declaration. # in user.rb devise :revokable # plus other devise modules If the user who received the revocation email follows the provided link and confirms revocation, the account will effectively be "revoked" and inactive, unable to log in. Additionally, you may want to override <tt>#revoke!</tt> to perfom additional revocation on the account, e.g. deleting posts made, resetting personal information, etc. The super method yields to a block for this purpose. # in user.rb def revoke! super do self.some_method_that_resets_me! end end That's about the extent of it. As with typical devise modules you can override the mailers and views with your own. Additionally you can define the module accessor <tt>@@mailer</tt> on the module with a proc to handle your mail if you need to. This proc is yielded two arguments, the method name (e.g. :revocation_instructions), and the affected resource. # in config/initializers/devise_revokable.rb require 'devise_revokable' require 'my_mailer' DeviseRevokable.mailer = proc {|method_name, resource| MyMailer.send(:method_name, resource) }

QA Robusta is an automation framework easing pain points away from automation test case writers. How is pain relieved? * Elements, such as links, buttons, and other html objects are defined in one location. This ensures over time the user won't have definitions spread out throughout different layers of code requiring time consuming updates if the application under test is modified. * Well defined flows allows the user to have a common means for navigating and controlling interactions with the application under test. This takes all logic out of test classes and yields in higher more modular code re-use. * When an application requiring testing has the elements and flows implemented less code savy resources can easily add new test cases once trained on how to access the flows and elements. * When ever a link or button is clicked a screen shot is taken * Results are available under site/results directory in html format. Report includes the rdoc on a per test class method along with any screen shots taken. Example report: https://cyberconnect.biz/opensource/demo_results.html * Transparent remote Unix command execution leading to well defined interfaces for common task. For example, one may have a class defined specifically for RemoteUnixNetwork. This class would have methods such as, assign_ip, ifup, ifdown, etc. This class then would be able to perform these task on any remote Unix machine. * Executes the same on Windows or Linux/Unix environments. Developers have the freedom to develop on the platform of choice. * Mechanize extension: Allows the user to define a web application's page elements in a YAML format and provide navigation paths accessing the YAML structure to interact with the web application. Users can also perform direct http.post or any other mechanize functionality when defining state-full interfaces to hit a web application without going through a browser.

# COM # COM is an object-oriented wrapper around WIN32OLE. COM makes it easy to add behavior to WIN32OLE objects, making them easier to work with from Ruby. ## Usage ## Using COM is rather straightforward. There’s basically four concepts to keep track of: 1. COM objects 2. Instantiable COM objects 3. COM events 4. COM errors Let’s look at each concept separately, using the following example as a base. module Word end class Word::Application < COM::Instantiable def without_interaction with_properties('displayalerts' => Word::WdAlertsNone){ yield } end def documents Word::Documents.new(com.documents) end def quit(saving = Word::WdDoNotSaveChanges, *args) com.quit saving, *args end end ### COM Objects ### A COM::Object is a wrapper around a COM object. It provides error specialization, which is discussed later and a few utility methods. You typically use it to wrap COM objects that are returned by COM methods. If we take the example given in the introduction, Word::Documents is a good candidate: class Word::Documents < COM::Object DefaultOpenOptions = { 'confirmconversions' => false, 'readonly' => true, 'addtorecentfiles' => false, 'visible' => false }.freeze def open(path, options = {}) options = DefaultOpenOptions.merge(options) options['filename'] = Pathname(path).to_com Word::Document.new(com.open(options)) end end Here we override the #open method to be a bit easier to use, providing sane defaults for COM interaction. Worth noting is the use of the #com method to access the actual COM object to invoke the #open method on it. Also note that Word::Document is also a COM::Object. COM::Object provides a convenience method called #with_properties, which is used in the #without_interaction method above. It lets you set properties on the COM::Object during the duration of a block, restoring them after it exits (successfully or with an error). ### Instantiable COM Objects ### Instantiable COM objects are COM objects that we can connect to and that can be created. The Word::Application object can, for example, be created. Instantiable COM objects should inherit from COM::Instantiable. Instantiable COM objects can be told what program ID to use, whether or not to allow connecting to an already running object, and to load its associated constants upon creation. The program ID is used to determine what instantiable COM object to connect to. By default the name of the COM::Instantiable class’ name is used, taking the last two double-colon-separated components and joining them with a dot. For Word::Application, the program ID is “Word.Application”. The program ID can be set by using the .program_id method: class IDontCare::ForConventions < COM::Instantiable program_id 'Word.Application' end The program ID can be accessed with the same method: Word::Application.program_id # ⇒ 'Word.Application' Connecting to an already running COM object is not done by default, but is sometimes desirable: the COM object might take a long time to create, or some common state needs to be accessed. If the default for a certain instantiable COM object should be to connect, this can be done using the .connect method: class Word::Application < COM::Instantiable connect end If no running COM object is available, then a new COM object will be created in its stead. Whether or not a class uses the connection method can be queried with the .connect? method: Word::Application.connect? # ⇒ true Whether or not to load constants associated with an instantiable COM object is set with the .constants method: class Word::Application < COM::Instantiable constants true end and can similarly be checked: Word::Application.constants? # ⇒ true Constants are loaded by default. When an instance of the instantiable COM object is created, a check is run to see if constants should be loaded and whether or not they already have been loaded. If they should be loaded and they haven’t already been loaded, they’re, you guessed it, loaded. The constants are added to the module containing the COM::Instantiable. Thus, for Word::Application, the Word module will contain all the constants. Whether or not the constants have already been loaded can be checked with .constants_loaded?: Word::Application.constants_loaded # ⇒ false That concludes the class-level methods. Let’s begin with the #connected? method among the instance-level methods. This method queries whether or not this instance connected to an already running COM object: Word::Application.new.connected? # ⇒ false This can be very important in determining how shutdown of a COM object should be done. If you connected to an already COM object it might be foolish to shut it down if someone else is using it. The #initialize method takes a couple of options: * connect: whether or not to connect to a running instance * constants: whether or not to load constants These options will, when given, override the class-level defaults. ### Events ### COM events are easily dealt with: class Word::Application < COM::Instantiable def initialize(options = {}) super @events = COM::Events.new(com, 'ApplicationEvents', 'OnQuit') end def quit(saving = Word::WdDoNotSaveChanges, *args) @events.observe('OnQuit', proc{ com.quit saving, *args }) do yield if block_given? end end end To tell you the truth this API sucks and will most likely be rewritten. The reason that it is the way it is is that WIN32OLE, which COM wraps, sucks. It’s event API is horrid and the implementation is buggy. It will keep every registered event block in memory for ever, freeing neither the blocks nor the COM objects that yield the events. ### Errors ### All errors generated by COM methods descend from COM::Error, except for those cases where a Ruby error already exists. The following HRESULT error codes are turned into Ruby errors: HRESULT Error Code | Error Class -------------------|------------ 0x80004001 | NotImplementedError 0x80020005 | TypeError 0x80020006 | NoMethodError 0x8002000e | ArgumentError 0x800401e4 | ArgumentError There are also a couple of other HRESULT error codes that are turned into more specific errors than COM::Error: HRESULT Error Code | Error Class -------------------|------------ 0x80020003 | MemberNotFoundError 0x800401e3 | OperationUnavailableError Finally, when a method results in any other error, a COM::MethodInvocationError will be raised, which can be queried for the specifics, specifically #message, #method, #server, #code, #hresult_code, and #hresult_message. ### Pathname ### The Pathname object receives an additional method, #to_com. This method is useful for when you want to pass a Pathname object to a COM method. Simply call #to_com to turn it into a String of the right encoding for COM: Word::Application.new.documents.open(Pathname('a.docx').to_com) # ⇒ Word::Document ## Installation ## Install COM with % gem install com ## License ## You may use, copy and redistribute this library under the same [terms][1] as Ruby itself.
