Results for empty-functions

Super basic gem for defining a javascript debug function that works in development and does nothing in production. Defines the debug function as an empty function in production for your enjoyment.

A function that splits a string into an Array of stripped, non-empty lines: Strip_Lines(" test \n \n test ")

With ActsAsTaggableOn, you could tag a single model on several contexts, such as skills, interests, and awards. It also provides other advanced functionality. This fork changes the behavior of tagged_with. It will return empty scope on empty or nil tag list.

Enumerator abstraction layer that emulates certain array functionality (methods like empty?, slice, shift and more) by using a small cache and other tricks without loading all the data from the enumerator at the same time.

Parse and generate Portable Action Notation (PAN) strings for representing atomic actions in abstract strategy board games including chess, shogi, xiangqi, and others. PAN provides an intuitive operator-based syntax with six core operators: "-" (move to empty square), "+" (capture), "~" (special moves with side effects), "*" (drop to board), "." (drop with capture), and "=" (in-place transformation), plus "..." (pass turn). Supports coordinates via CELL specification and piece identifiers via EPIN specification. Handles transformations ("e7-e8=Q"), enhanced/diminished states ("+R", "-P"), and style derivation markers ("K'"). Provides comprehensive validation, immutable action objects, and functional API design. Examples: "e2-e4" (move), "d1+f3" (capture), "e1~g1" (castling), "P*e5" (drop), "e7-e8=Q" (promotion), "..." (pass), "+d4" (static capture), "e4=+P" (modify).

# Excel to Code [](https://travis-ci.org/tamc/excel_to_code) excel_to_c - roughly translate some Excel files into C. excel_to_ruby - roughly translate some Excel files into Ruby. This allows spreadsheets to be: 1. Embedded in other programs, such as web servers, or optimisers 2. Without depending on any Microsoft code For example, running [these commands](examples/simple/compile.sh) turns [this spreadsheet](examples/simple/simple.xlsx) into [this Ruby code](examples/simple/ruby/simple.rb) or [this C code](examples/simple/c/simple.c). # Install Requires Ruby. Install by: gem install excel_to_code # Run To just have a go: excel_to_c <excel_file_name> This will produce a file called excelspreadsheet.c For a more complex spreadsheet: excel_to_c --compile --run-tests --settable <name of input worksheet> --prune-except <name of output worksheet> <excel file name> See the full list of options: excel_to_c --help # Gotchas, limitations and bugs 0. No custom functions, no macros for generating results 1. Results are cached. So you must call reset(), then set values, then read values. 2. It must be possible to replace INDIRECT and OFFSET formula with standard references at compile time (e.g., INDIRECT("A"&"1") is fine, INDIRECT(userInput&"3") is not. 3. Doesn't implement all functions. [See which functions are implemented](docs/Which_functions_are_implemented.md). 4. Doesn't implement references that involve range unions and lists (but does implement standard ranges) 5. Sometimes gives cells as being empty, when excel would give the cell as having a numeric value of zero 6. The generated C version does not multithread and will give bad results if you try. 7. The generated code uses floating point, rather than fully precise arithmetic, so results can differ slightly. 8. The generated code uses the sprintf approach to rounding (even-odd) rather than excel's 0.5 rounds away from zero. 9. Ranges like this: Sheet1!A10:Sheet1!B20 and 3D ranges don't work.

LCN (Location Condition Notation) provides a rule-agnostic format for describing location conditions in abstract strategy board games. This gem implements the LCN Specification v1.0.0 with a modern Ruby interface featuring immutable condition objects and functional programming principles. LCN enables standardized representation of environmental constraints on board locations using reserved keywords ("empty", "enemy") and QPI piece identifiers with CELL coordinate system integration. Perfect for movement validation, pre-condition checking, constraint evaluation, and rule-agnostic game logic requiring precise location state requirements across multiple game types and traditions.

GQLite is a Rust-language library, with a C interface, that implements a small, fast, self-contained, high-reliability, full-featured, Graph Query database engine. GQLite support multiple database backends, such as SQLite and redb. This enable to achieve high performance and for application to combine Graph queries with traditional SQL queries. GQLite source code is license under the [MIT License](LICENSE) and is free to everyone to use for any purpose. The official repositories contains bindings/APIs for C, C++, Python, Ruby and Crystal. The library is still in its early stage, but it is now fully functional. Development effort has now slowed down and new features are added on a by-need basis. It supports a subset of OpenCypher, with some ISO GQL extensions. Example of use -------------- ```ruby require 'gqlite' begin # Create a database on the file "test.db" connection = GQLite::Connection.new filename: "test.db" # Execute a simple query to create a node and return all the nodes value = connection.execute_oc_query("CREATE () MATCH (n) RETURN n") # Print the result if value.nil? puts "Empty results" else puts "Results are #{value.to_s}" end rescue GQLite::Error => ex # Report any error puts "An error has occured: #{ex.message}" end ``` The documentation for the GQL query language can found in [OpenCypher](https://auksys.org/documentation/5/libraries/gqlite/opencypher/) and for the [API](https://auksys.org/documentation/5/libraries/gqlite/api/).

# Fresh::Auth This gem makes it really, REALLY easy to use the Freshbooks API. It couldn't be easier. With only 3 functions you'll ever need to use, and only 2 required configuration values, it can't get any easier. ## Installation Add this line to your application's Gemfile: gem 'fresh-auth' And then execute: $ bundle Or install it yourself as: $ gem install fresh-auth ## Usage ### Configuration: You must define your Freshbooks subdomain and your OAuth Secret in your application code before using Fresh::Auth. For Ruby on Rails apps, a new file at config/initializers/fresh-auth.rb would be appropriate. Your configuration file should look like this (you fill in the three empty strings): Fresh::Auth.configure do |config| # The part of your login url between 'http://' and '.freshbooks.com' config.url.subdomain = "" # Under 'My Account' (on the top right when you're logged into Freshbooks) # -> 'Freshbooks API' -> 'OAuth Developer Access' -> 'OAuth Secret' # You'll need to request this from Freshbooks initially. config.oauth_secret = "" # Optional. Any string of your choice. Be creative or check out http://www.thebitmill.com/tools/password.html config.nonce_salt = "" end Fear not: If you try to use Fresh::Auth without configuring it first, an exception will be thrown that clearly describes the problem. ### Public API: There are two modules in this API: Fresh::Auth::Authentication and Fresh::Auth::Api #### Fresh::Auth::Authentication This module authenticates you with Freshbooks, storing the authentication in an array called `session`. This integrates seamlessly with Ruby on Rails' controller environment. If you're using some framework other than Ruby on Rails, make sure to define session in your class before including the Authentication module. This isn't recommended because your class will also need to define other objects called `params` and `request` and implement a `redirect_to` method. It gets complicated. Better leave it to Rails to handle this for you. The only public function of this module is AuthenticateWithFreshbooks. To use it, just add the following line of code to your controller: ` include Fresh::Auth::Authentication ` Then, the following line of code authenticates with Freshbooks from any method in your controller: ` AuthenticateWithFreshbooks() ` Note that, after authenticating with Freshbooks, the user will be redirected back to the same path using HTTP GET, so make sure the resource supports HTTP GET and that in the business logic executed on GET, AuthenticateWihFreshbooks() is called. #### Fresh::Auth::Api Once you've authenticated, you want to send XML requests to Freshbooks. The first step is preparing the XML with Fresh::Auth::Api.GenerateXml, which you'll supply with a block that defines all the nested XML that you want in your request. GenerateXml also takes two arguments before the block: the class and method that you want to call. First, in your controller: `include Fresh::Auth::Api` Then, in some method in that controller: my_xml = GenerateXml :invoice, :update do |xml| xml.client_id 20 xml.status 'sent' xml.notes 'Pick up the car by 5' xml.terms 'Cash only' xml.lines { xml.line { xml.name 'catalytic converter' xml.quantity 1 xml.unit_cost 450 xml.type 'Item' } xml.line { xml.name 'labor' xml.quantity 1 xml.unit_cost 60 xml.type 'Time' } } end Ok, you created the XML. Now you want to send it. Sounds pretty complicated, right? Not at all! Ready? Let's go! `_response = PostToFreshbooksApi my_xml` Now, are you wondering what's in `_response`? I'll tell you shortly, but before we discuss that, we have to know about the exception that PostToFreshbooksApi might raise. It raises a detailed error message if the response status is not 'ok'. Makes sense, right? Now, you still want to know what's in `_response`? Oh, nothing fancy. Just a Nokogiri XML object, representing the root element of the xml response. Could this get any easier? ## Contributing 1. Fork it 2. Create your feature branch (`git checkout -b my-new-feature`) 3. Commit your changes (`git commit -am 'Added some feature'`) 4. Push to the branch (`git push origin my-new-feature`) 5. Create new Pull Request

Running bundle exec rspec ./spec should show all tests passing. To clean up the autogenerated Makefile and the compiled objects: cd ext/ make realclean If you need to regenerate the ruby interface functions `heyes_wrap.cxx`, run: cd swig/ swig -c++ -ruby heyes.i mv heyes_wrap.cxx ../ext If you are just trying to run the tests: rake build gem install pkg/castar-0.0.1.gem builds the gem and installs it to your local machine. gem which castar tells you where it is. You can then cd to that directory and run the tests as above (but since you're not in a git repo you can't commit them). I followed the instructions [here](https://github.com/radar/guides/blob/master/gem-development.md) for using Bundler to create the gem. ## INSTALL: * gem install castar ## LICENSE: (The MIT License)

Value Value is a library for defining immutable value objects in Ruby. A value object is an object whose equality to other objects is determined by its value, not its identity, think dates and amounts of money. A value object should also be immutable, as you don’t want the date “2013-04-22” itself to change but the current date to change from “2013-04-22” to “2013-04-23”. That is, you don’t want entries in a calendar for 2013-04-22 to move to 2013-04-23 simply because the current date changes from 2013-04-22 to 2013-04-23. A value object consists of one or more attributes stored in instance variables. Value sets up an #initialize method for you that let’s you set these attributes, as, value objects being immutable, this’ll be your only chance to do so. Value also adds equality checks ‹#==› and ‹#eql?› (which are themselves equivalent), a ‹#hash› method, a nice ‹#inspect› method, and a protected attribute reader for each attribute. You may of course add any additional methods that your value object will benefit from. That’s basically all there’s too it. Let’s now look at using the Value library. § Usage You create value object class by invoking ‹#Value› inside the class (module) you wish to make into a value object class. Let’s create a class that represent points on a plane: class Point Value :x, :y end A ‹Point› is thus a value object consisting of two sub-values ‹x› and ‹y› (the coordinates). Just from invoking ‹#Value›, a ‹Point› object will have a constructor that takes two arguments to set instance variables ‹@x› and ‹@y›, equality checks ‹#==› and ‹#eql?› (which are the same), a ‹#hash› method, a nice ‹#inspect› method, and two protected attribute readers ‹#x› and ‹#y›. We can thus already creat ‹Point›s: origo = Point.new(0, 0) The default of making the attribute readers protected is often good practice, but for a ‹Point› it probably makes sense to be able to access its coordinates: class Point public(*attributes) end This’ll make all attributes of ‹Point› public. You can of course choose to only make certain attributes public: class Point public :x end Note that this public is standard Ruby functionality. Adding a method to ‹Point› is of course also possible and very much Rubyish: class Point def distance(other) Math.sqrt((other.x - x)**2 + (other.y - y)**2) end end For some value object classes you might want to support optional attributes. This is done by providing a default value for the attribute, like so: class Money Value :amount, [:currency, :USD] end Here, the ‹currency› attribute will default to ‹:USD›. You can create ‹Money› via dollars = Money.new(2) but also kronor = Money.new(2, :SEK) All required attributes must come before any optional attributes. Splat attributes are also supported: class List Value :'*elements' end empty = List.new suits = List.new(:spades, :hearts, :diamonds, :clubs) Splat attributes are optional. Finally, block attributes are also available: class Block Value :'&block' end block = Block.new{ |e| e * 2 } Block attributes are optional. Comparison beyond ‹#==› is possible by specifingy the ‹:comparable› option to ‹#Value›, listing one or more attributes that should be included in the comparison: class Vector Value :a, :b, :comparable => :a end Note that equality (‹#==› and ‹#eql?›) is always defined based on all attributes, regardless of arguments to ‹:comparable›. Here we say that comparisons between ‹Vector›s should be made between the values of the ‹a› attribute only. We can also make comparisons between all attributes of a value object: class Vector Value :a, :b, :comparable => true end To sum things up, let’s use all possible arguments to ‹#Value› at once: class Method Value :file, :line, [:name, 'unnamed'], :'*args', :'&block', :comparable => [:file, :line] end A ‹Method› consists of file and line information, a possible name, some arguments, possibly a block, and is comparable on the file and line on which they appear.
