This gem is for printing hyperlinks in supported terminal emulators. It is a simple wrapper that abstracts the ANSI characters usually required to achieve this, which are annoying to type out. Check out the gist that inspired this gem at: https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda

RubyBreaker is a dynamic type documentation/checking tool for Ruby. It dynamically instruments code, monitors objects during execution, performs dynamic type checking, and generates type documentation based on the profiled information. RubyBreaker helps Ruby programs "break" out of obscurities and convolutions by auto-documenting type information.

Pronto runner for Sorbet, a static type checker for Ruby

Return a variable if it's present (and optionally of the right type), otherwise a default or nil. Adds a top level demand() method, which replaces long lines of repetitive code to check for nil?/present?/empty?, etc., hard-to-read ternary operators (?:) and if statements. A block can also be specified, which only runs (with the variable) if the checks pass.

Custom form field_tag of range-slider with text_field type selector. You can either choose from drop down or enter your own value and the slider will auto-adjust or you can use the slider to adjust values. This all through on form field f.slide_selector.

A puppet-lint plugin to check for classes and defined types that contain names beginning with a digit.

a Rails gem that allows you to validate a URL entered in a form. It validates if the URL exists by hitting it with a HEAD request. The improved version includes retries for common patterns when the head request is refused before giving a failure notice. It also looks up a SITE_URL constant to the user agent in the headers. Also has the option to also check that the URL returns content of a specified type.

strong_csv is a type checker for a CSV file. It lets developers declare types for each column to ensure all cells are satisfied with desired types.

Allows for easy YAML parsing and type checking, as well as generators

rubber-c-binder allows a rubyish means of generating bindings for C libraries, including (but not limited to) GObject based libraries. It allows C code to be written in the context of a ruby style class/method layout and eases type checking and conversion between Ruby & C datatypes.

yae provides a simple enum class (enumerated type) implementation (Yae::Enum) that can be used to abstract a set of values. It also provides methods to check values existence in the enum and to iterate over its contents.

Allows you check if an object match a class expression. It is typically used to check the type of method paraameters. It is an alternative to using Ruby-3 .rbs files but with a different syntax and only dynamic checks Typically you'll include the Constrain module and use #constrain to check the type of method parameters: include Constrain # f takes a String and an array of Integer objects. Raise a Constrain::Error # if parameters doesn't have the expected types def f(a, b) constrain a, String constrain b, [Integer] end Constrain works with ruby-2 (and maybe ruby-3)

TypedOperation is a command pattern implementation where inputs can be defined with runtime type checks. Operations can be partially applied.

Have 3-state radiobuttons instead of a 2-state checkbox for your Boolean columns which can store NULL. This gem: 1. Provides a custom Formtastic input type `:tristate_radio` which renders 3 radios (“Yes”, “No”, “Unset”) instead of a checkbox (only where you put it). 2. Teaches Rails recognize `"null"` and `"nil"` param values as `nil` 3. Encourages you to add translations for ActiveAdmin “status tag” so that `nil` be correctly translated as “Unset” instead of “False”. Does not change controls, you need to turn it on via `as: :tristate_radio` option.

Platform Agnostic SEcurity TOkens are a specification for secure stateless tokens. This is an implementation of PASETO tokens, and the PASERK key management extensions, in ruby, with runtime static type checking provided by Sorbet.

The suckysockets gem provides the user with the opportunity to check whether a power adapter is needed when travelling from one country to another. 1. How to install the gem gem install suckysockets 2. How to use it To run the program just type 'suckysockets' in the command line. You will be asked in which country you currently live. Please type the country name and press 'enter'. Next you need to enter your destination country and press 'enter' again. Then you receive the result telling you whether or nor you need an adapter travelling from you current country to the destination country. Three outcomes are possible: - an adapter is not needed. That is the case when all plugs common in your country of living fit all of the sockets in your destination country. - an adapter is definetely needed. That is the case when none of the plugs in your home country fit any of the sockets in your destination country. - an adapter is needed in certain cases: when some of your home country plugs fit some of the sockets, but some plugs don't. In that case you will get a detailed response telling you for which particular cases an adapter is needed.

In most cases Ruby doesn't need templated classes, nor any other system of generics, because it isn't statically type checked. However, sometimes we need to automatically generate multiple similar classes, either because of poor design or because of external necessities. For example, to define a GraphQL schema with GraphQL Ruby (https://graphql-ruby.org/) we need to define a distinct class for each type. Since GraphQL is statically type checked but doesn't provide generics, if we need a set of similar but distinct types we're left to define them one by one.

A modern modular service object toolkit for Rails, that respects database transactions and adds type checks to returned values.
