Type checking and type casting of parameters for Action Pack

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

Sorbet's runtime type checking component

RDL is a gem that adds types and contracts to Ruby. RDL includes extensive support for specifying method types, which can either be enforced as contracts or statically checked.

Flags is a framework for Ruby which allows the definition of command-line flags, which are parsed in and can be accessed smartly from within your Ruby code. This framework allows for numerous different flag types, and takes care of the process of type conversion and flag validation (type and value checking).

== Description A Rack compatible JSON-RPC2 server domain specific language (DSL) - allows JSONRPC APIs to be defined as mountable Rack applications with inline documentation, authentication and type checking. e.g. class Calculator < JSONRPC2::Interface title "JSON-RPC2 Calculator" introduction "This interface allows basic maths calculations via JSON-RPC2" auth_with JSONRPC2::BasicAuth.new({'user' => 'secretword'}) section 'Simple Ops' do desc 'Multiply two numbers' param 'a', 'Number', 'a' param 'b', 'Number', 'b' result 'Number', 'a * b' def mul args args['a'] * args['b'] end desc 'Add numbers' example "Calculate 1 + 1 = 2", :params => { 'a' => 1, 'b' => 1}, :result => 2 param 'a', 'Number', 'First number' param 'b', 'Number', 'Second number' optional 'c', 'Number', 'Third number' result 'Number', 'a + b + c' def sum args val = args['a'] + args['b'] val += args['c'] if args['c'] val end end end

Normally Rails/Rack only checks the '_method' parameter in POST requests, but JSONP requests are always GETs. This railtie enables the '_method' check for all request types, including GET.

MooseX is an extension of Ruby object DSL. The main goal of MooseX is to make Ruby Object Oriented programming easier, more consistent, and less tedious. With MooseX you can think more about what you want to do and less about the mechanics of OOP. It is a port of Moose/Moo from Perl to Ruby world, providing method delegation, type check, traits, monads, plugins, lazy attributes, aspects and much more.

A gem that provides DSL for serialization of plain old Ruby objects to JSON in a declarative style by defining a `schema`. It also provides a trivial type checking in the runtime before serialization.

# Rake::ToolkitProgram Create toolkit programs easily with `Rake` and `OptionParser` syntax. Bash completions and usage help are baked in. ## Installation Add this line to your application's Gemfile: ```ruby gem 'rake-toolkit_program' ``` And then execute: $ bundle Or install it yourself as: $ gem install rake-toolkit_program ## Quickstart * Shebang it up (in a file named `awesome_tool.rb`) ```ruby #!/usr/bin/env ruby ``` * Require the library ```ruby require 'rake/toolkit_program' ``` * Make your life easier ```ruby Program = Rake::ToolkitProgram ``` * Define your command tasks ```ruby Program.command_tasks do desc "Build it" task 'build' do # Ruby code here end desc "Test it" task 'test' => ['build'] do # Rake syntax ↑↑↑↑↑↑↑ for dependencies # Ruby code here end end ``` You can use `Program.args` in your tasks to access the other arguments on the command line. For argument parsing integrated into the help provided by the program, see the use of `Rake::Task(Rake::ToolkitProgram::TaskExt)#parse_args` below. * Wire the mainline ```ruby Program.run(on_error: :exit_program!) if $0 == __FILE__ ``` * In the shell, prepare to run the program (UNIX/Linux systems only) ```console $ chmod +x awesome_tool.rb $ ./awesome_tool.rb --install-completions Completions installed in /home/rtweeks/.bashrc Source /home/rtweeks/.bash-complete/awesome_tool.rb-completions for immediate availability. $ source /home/rtweeks/.bash-complete/awesome_tool.rb-completions ``` * Ask for help ```console $ ./awesome_tool.rb help *** ./awesome_tool.rb Toolkit Program *** . . . ``` ## Usage Let's look at a short sample toolkit program -- put this in `awesome.rb`: ```ruby #!/usr/bin/env ruby require 'rake/toolkit_program' require 'ostruct' ToolkitProgram = Rake::ToolkitProgram ToolkitProgram.title = "My Awesome Toolkit of Awesome" ToolkitProgram.command_tasks do desc <<-END_DESC.dedent Fooing myself I'm not sure what I'm doing, but I'm definitely fooing! END_DESC task :foo do a = ToolkitProgram.args puts "I'm fooed#{' on a ' if a.implement}#{a.implement}" end.parse_args(into: OpenStruct.new) do |parser, args| parser.no_positional_args! parser.on('-i', '--implement IMPLEMENT', 'An implement on which to be fooed') do |val| args.implement = val end end end if __FILE__ == $0 ToolkitProgram.run(on_error: :exit_program!) end ``` Make sure to `chmod +x awesome.rb`! What does this support? $ ./awesome.rb foo I'm fooed $ ./awesome.rb --help *** My Awesome Toolkit of Awesome *** Usage: ./awesome.rb COMMAND [OPTION ...] Avaliable options vary depending on the command given. For details of a particular command, use: ./awesome.rb help COMMAND Commands: foo Fooing myself help Show a list of commands or details of one command Use help COMMAND to get more help on a specific command. $ ./awesome.rb help foo *** My Awesome Toolkit of Awesome *** Usage: ./awesome.rb foo [OPTION ...] Fooing myself I'm not sure what I'm doing, but I'm definitely fooing! Options: -i, --implement IMPLEMENT An implement on which to be fooed $ ./awesome.rb --install-completions Completions installed in /home/rtweeks/.bashrc Source /home/rtweeks/.bash-complete/awesome.rb-completions for immediate availability. $ source /home/rtweeks/.bash-complete/awesome.rb-completions $ ./awesome.rb <tab><tab> foo help $ ./awesome.rb f<tab> ↳ ./awesome.rb foo $ ./awesome.rb foo <tab> ↳ ./awesome.rb foo -- $ ./awesome.rb foo --<tab><tab> --help --implement $ ./awesome.rb foo --i<tab> ↳ ./awesome.rb foo --implement $ ./awesome.rb foo --implement <tab><tab> --help awesome.rb $ ./awesome.rb foo --implement spoon I'm fooed on a spoon ### Defining Toolkit Commands Just define tasks in the block of `Rake::ToolkitProgram.command_tasks` with `task` (i.e. `Rake::DSL#task`). If `desc` is used to provide a description, the task will become visible in help and completions. When a command task is initially defined, positional arguments to the command are available as an `Array` through `Rake::ToolkitProgram.args`. ### Option Parsing This gem extends `Rake::Task` with a `#parse_args` method that creates a `Rake::ToolkitProgram::CommandOptionParser` (derived from the standard library's `OptionParser`) and an argument accumulator and `yield`s them to its block. * The arguments accumulated through the `Rake::ToolkitProgram::CommandOptionParser` are available to the task in `Rake::ToolkitProgram.args`, replacing the normal `Array` of positional arguments. * Use the `into:` keyword of `#parse_args` to provide a custom argument accumulator object for the associated command. The default argument accumulator constructor can be defined with `Rake::ToolkitProgram.default_parsed_args`. Without either of these, the default accumulator is a `Hash`. * Options defined using `OptionParser#on` (or any of the variants) will print in the help for the associated command. ### Positional Arguments Accessing positional arguments given after the command name depends on whether or not `Rake::Task(Rake::ToolkitProgram::TaskExt)#parse_args` has been called on the command task. If this method is not called, positional arguments will be an `Array` accessible through `Rake::ToolkitProgram.args`. When `Rake::Task(Rake::ToolkitProgram::TaskExt)#parse_args` is used: * `Rake::ToolkitProgram::CommandOptionParser#capture_positionals` can be used to define how positional arguments are accumulated. * If the argument accumulator is a `Hash`, the default (without calling this method) is to assign the `Array` of positional arguments to the `nil` key of the `Hash`. * For other types of accumulators, the positional arguments are only accessible if `Rake::ToolkitProgram::CommandOptionParser#capture_positionals` is used to define how they are captured. * If a block is given to this method, the block of the method will receive the `Array` of positional arguments. If it is passed an argument value, that value is used as the key under which to store the positional arguments if the argument accumulator is a `Hash`. * `Rake::ToolkitProgram::CommandOptionParser#expect_positional_cardinality` can be used to set a rule for the count of positional arguments. This will affect the _usage_ presented in the help for the associated command. * `Rake::ToolkitProgram::CommandOptionParser#map_positional_args` may be used to transform (or otherwise process) positional arguments one at a time and in the context of options and/or arguments appearing earlier on the command line. ### Convenience Methods * `Rake::Task(Rake::ToolkitProgram::TaskExt)#prohibit_args` is a quick way, for commands that accept no options or positional arguments, to declare this so the help and bash completions reflect this. It is equivalent to using `#parse_args` and telling the parser `parser.expect_positional_cardinality(0)`. * `Rake::ToolkitProgram::CommandOptionParser#no_positional_args!` is a shortcut for calling `#expect_positional_cardinality(0)` on the same object. * `Rake::Task(Rake::ToolkitProgram::TaskExt)#invalid_args!` and `Rake::ToolkitProgram::CommandOptionParser#invalid_args!` are convenient ways to raise `Rake::ToolkitProgram::InvalidCommandLine` with a message. ## OptionParser in Rubies Before and After v2.4 The `OptionParser` class was extended in Ruby 2.4 to simplify capturing options into a `Hash` or other container implementing `#[]=` in a similar way. This gem supports that, but it means that behavior varies somewhat between the pre-2.4 era and the 2.4+ era. To have consistent behavior across that version change, the recommendation is to use a `Struct`, `OpenStruct`, or custom class to hold program options rather than `Hash`. ## Development After checking out the repo, run `bin/setup` to install dependencies. You can also run `bin/console` for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). To run the tests, use `rake`, `rake test`, or `rspec spec`. Tests can only be run on systems that support `Kernel#fork`, as this is used to present a pristine and isolated environment for setting up the tool. If run using Ruby 2.3 or earlier, some tests will be pending because functionality expects Ruby 2.4's `OptionParser`. ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/PayTrace/rake-toolkit_program.

A type coercion lib works with Sorbet's static type checker and type definitions; raises an error if the coercion fails.

A new check for puppet-lint that validates that all parameters are typed.

Enums, properties, generics, structured objects and runtime type checking.

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.

A puppet-lint plugin to check that Optional class/defined type parameters don't default to anything other than `undef`.

Type checking for Ruby methods.

Yadriggy builds the abstract syntax tree (AST) of a method, checks its syntax and types, and runs it. When checking the syntax and types, it is treated as the code written in a domain specific language (DSL). It also provide simple DSLs for computation offloading from Ruby to C, Python, etc.

Built to support all types of checkout integration between Akatus and your application

This gem allows you to check the Content-Type of any HTTP-accessible asset.

Makes sure users don't accidentally create an account for the wrong e-mail address. Because 'gmial' isn't actually what they meant to type. Similarly, 'yaho.com', or the strange-but-true '.c0m'. Not even making that one up. If you're concerned about false-positives, it's super-easy to check. There's only a single method. Also, it's fully-tested.
